triplet specified in this manual (see technical data).
important for small children, elderly or infirm persons: As is the case with all
heating devices, it is expedient that you attach a protective guard - (change
fixture to guard) for these groups of persons, as the view pane and the
cladding parts of the stove can become extremely hot Caution: Risk of burn
injuries!
Never leave these groups of persons unattended near the stove when a
fire is burning or has just been extinguished! The stove should never be
operated for an extended period of time unattended.

OUR STOVES ARE TESTED IN ACCORDANCE WITH DIN EN 13240. DECLA-
RATION OF PERFORMANCE IS AVAILABLE AND CAN BE VIEWED AT WWW.
SPARTHERM.COM
These stoves have self-closing combustion chamber doors which means the
doors are only opened when the fireplace has to be serviced (e.g., to clean
the combustion chamber or add more fuel). For safety reasons, the closing
mechanism must not be tampered with; furthermore, any such action would
render the warranty and operating licence null and void. The guarantee and
operating licence are also rendered invalid if the customer modified the
technology of any other area of the stove.

2.3.3 ASSEMBLY OF THE HEAT STORAGE MASS
ambiente a3/a3 RLU/a4/a4 RLU
Storage stones can only be fitted or retrofitted to the ambiente a3 and a4
models.
If the ambiente a3 or a4 is ordered with storage stones, the front stone
and supporting plate are already fitted at the factory. For weight reasons,
the other storage stones are assembled on site. Stoves are supplied with
a rear flue gas connection as standard, unless otherwise specified at the
time of ordering.
To install the storage stones, start by removing the cover. Note that
the stove should not yet be connected to the chimney when doing this.
13
ambiente a4 with top flue gas
connection:
Start by placing the six tall stones in
position to form a ring. These have
a recessed handle on the inside to
facilitate assembly. Now place the
three shallow stones in position to
form a ring and replace the lid (Fig.
6c).
ambiente a4 with side flue gas
connection:
Start by placing the two small stones
under the flue gas elbow pipe, and
then place the four tall stones in
position. These have a recessed
handle on the inside to facilitate
assembly. Now place the two shal-
low stones in position and replace
the lid (Fig. 6d)
Fitting the front stone:
(Only if retro fitting storage stones). Firstly fit the front stone (A). Next, fit
the supporting plate (B) (Fig. 6a).

Controlling the heat output to the storage
system:
(ambiente a3 and a4)
The heat output to the storage stones can be
controlled via the adjustment lever (Fig. 6e). If
the adjustment lever is moved to the ‘+’ posi-
tion, the convective heat is transmitted directly
from the stove to the room. The room will warm
up faster at this setting. If the adjustment lever
is set to the ‘-’ position, the convective heat
will remain in the storage stones for longer.
The heat is stored in the stove and slowly released to the room after the fire
has gone out. The stove will continue to provide a cosy warmth even when
the fire has gone out.
ambiente a5
The ambiente a5 stove can be optionally fitted with storage stones for pro-
longed heat storage.
Proceed as follows to fit the stones: In order to fit
storage stones to the ambiente a5 stove, the first step is to remove the
stove top lid (Fig. 7a).
Now push the ‘front’ storage stone (WxHxD 310 mm x 285 mm x 30 mm)
into the front locating slot (Fig. 7b). Next, place the two ‘back’ storage
stones (WxHxD 250 mm x 390 mm x 30 mm) in the locating slot at the rear
of the body (Fig. 7c). Place the ‘top’ storage stones (Fig. 7d - 7h) on the top
plate of the stove body, according to whether the stove has a top or rear
flue gas connection. This example shows a rear flue gas connection. After
putting the storage stones in position, replace the stove top lid (Fig. 7i - 7j).

The Magnetherm storage stone filling is supplied separately with the ambi-
ente a6 with a heat accumulator attachment for weight reasons. To fill the
heat storage mass firstly remove the top lid of the stove and then the two
attachment lids. Then slowly and carefully fill the Magnatherm filling in the
heat accumulator attachment. It must be ensured that no stones are in the
central flue dome! Upon completion, replace both attachment lids and the
top plate.

2.4 COMBUSTION AIR SUPPLY
The combustion air supply can be provided in various ways as described in
sections 2.4.1 Non-room air sealed operation (RLA), 2.4.2 Room air sealed
operation (RLU) and 2.4.3 Separate combustion air supply.
2.4.1 NON-ROOM AIR SEALED OPERATION (RLA)
Your ambiente a1/a2/a3/a4/a4H2O/a5/a6/a6 H2O/a7/a8 stove draws the air
it needs for combustion from the room where it is installed (non-room air
sealed operation). An adequate supply of fresh air must be ensured in the
room where the stove is installed (for further details refer to the heating
systems regulations for the country concerned, DIN 18896, the technical
rules, etc.). The fresh air supply must be checked by the installer and the
operator. When operating several fireplaces in a single room or linked space
, ensure that sufficient air is available for complete combustion! It is possi-
ble that there is not a sufficient supply of fresh air if the windows and doors
are sealed (e.g., in combination with energy saving measures). As a result,
the ventilation of the stove can be affected. This can adversely affect your
well-being and, potentially, your safety. If necessary, an additional air supply
can be provided by fitting an air inlet near the stove or by fitting a combustion air
intake pipe which connects with the external air (see page 16), or with a well
ventilated room (not the room where the stove is installed). In particular, ensure
that the necessary combustion air pipes are open during the operation of the
fireplace insert. Simultaneous operation with a ventilation system (e.g. extractor
hood, bathroom fan, etc.) in the same room or connected space can adversely
affect the function of the fireplace (to the point of smoke or flue gas accumulat-
ing in the living room, despite the combustion chamber door being closed). It is
therefore prohibited to operate appliances of this kind simultaneously with a stove
without first taking appropriate precautionary measures.
2.4.2 ROOM AIR SEALED OPERATION (RLU)
The RLU stoves have been developed for combination with domestic ventila-
tion systems for a vacuum of up to 8 Pa in the room in which they are installed
and can be operated without additional safety measures. For room air sealed
operation the combustion air must be guided via tight lines from outside or
conveyed to the system via an air-exhaust system. To this end, the combustion
air channel must be permanently tightly connected to the combustion air noz-
zle (rear/side/bottom connection) of the stove.
Upon connecting a RLU stove to the combustion air line, the information
from the German Association of Stove and Hot-Air Heating Systems (TROL
technical rules), DIN 18896 etc. must be observed. Sufficient dimensioning
in particular must be ensured.
Country-specific and local fire safety regulations must be observed! Make
sure that the pipelines are always tight.
2.4.3 SEPARATE COMBUSTION AIR SUPPLY
It is possible to provide the stove with a separate combustion air supply. The separate
combustion air connection is located at the rear of the appliance or below it. The
nozzle is ready-assembled. The stove covering can be opened up for the purpose.
When connecting a pipe connection to the combustion air connection nozzle, the
combustion air is supplied to the stove from outside or from other rooms, e.g., the
cellar. When connecting up the stove to a combustion air pipe, the requirements of
TROL (technical rules), DIN 18896, etc. must be observed and applied.
In particular, sufficient dimensioning of the pipes must be ensured! If using
a rotary base, a permanently flexible connection must be made! The rotat-
ing action must not be restricted.
Chapter 2
17
Combustion air intakes and pipes must not be obstructed or closed unless special
safety devices are fitted to ensure that the stove can only be operated when the
closing system is open. The cross-section must not be narrowed by a fastening or a
grille. This measure is not necessary with air/exhaust chimneys. If the combustion air
pipe has to be routed out of the building, a shut-off device must be fitted. The position
of the shut-off device must be identifiable from outside. In the case of an external
connection the pipe should be insulated, as condensate may form. Also, when fitting
the pipe it should be ensured that no water or other substances can enter the stove
and that any condensate can drain away outside.
According to the relevant provisions, combustion air lines that bridge firewalls in
buildings with more than two full storeys must be constructed such that
fire and smoke cannot spread to other storeys or fire lobbies. Country-specific and
local fire safety regulations must be observed!
Special instructions for the ambiente a1 and a2
With a combustion air connection with SQC (Spartherm Quick Coupling), the stove is
to be connected as follows.
The stove installation site must be fitted with a supply channel / bore as per the
technical instructions. When mounted directly on the wall, the combustion air and
flue gas connection must be level. The stove is supplied with the mounted SQC and
turned out feet. In this state, the nozzle is in the air and not in contact with the floor.
As such, the stove can be transported with the usual aids (e.g., hand truck).

Installation on underside of stove for a7 and a8:
Stand the stove on the floor above the combustion air connection. Now
carefully lift off the stove covering. (Fig. 10a). Next, unscrew the screw
cap. (Fig. 10b). Connect the combustion air nozzle to the flexible, extensible
combustion air line installed on site. If the combustion air connection is rigid
at floor level, the separate combustion air nozzle supplied must be pushed
into the connection to form an airtight seal.
Installation at rear of stove for a7:
Start by unscrewing the screw cap (Fig. 10c). Now fit the combustion air
nozzle (Fig. 10d). Lastly, connect the combustion air nozzle with the com-
bustion air line.
2.5 FIRE PROTECTION
General information about fire protection
Stoves are heating systems and are subject to regulations and essential fire precau-
tions. The fire precautions and minimum distances should be borne in mind when
selecting the installation location for the stove. A minimum distance of 5 cm
from the rear wall must always be maintained. Greater distances should be
allowed for reasons of safety and fire prevention in the case of walls that
need to be protected or combustible building components.
The table that follows shows the distances that must be maintained according to the
type of stove and the installation situation on site. Use the drawings (Figs. 12-14) to
help you determine your particular installation situation and note the distances that
must be maintained.
Note the fire precautions when installing the stove. Ask your local chimney
sweep for advice.

Their structure and materials enable non-combustible mounting walls not in need
of protection to be permanently exposed to temperatures above 85°C.
Combustible mounting walls in need of protection (e.g. stud partition construction)
must be protected from temperatures above 85°C.
The mounting walls should be assessed before installing the stove. If the nature of the
mounting wall cannot be identified with certainty, a specialist (such as the chimney
sweep) should be consulted.
According to DIN 4102-1, wallpaper used as a wall covering is not considered a
combustible building component and does not require any special precautions.
Please note that the underlying structure of wallpaper (e.g., stud partition construc-
tion) may well be combustible or in need of protection and the relevant precautions
must be taken.
Please note that the minimum distances indicated from rear walls and side walls
need to be adapted for rotating stoves.
It is important to observe the minimum distance from the chimney connecting piece
to combustible building components („2.7 Connecting pieces“ on page 22).
There must be no combustible objects within a radius of 50 cm above the stove.
Floor coverings near the stove
Floors made from combustible materials in front of the combustion chamber door must
be protected by a covering of non-combustible materials. This covering should extend
at least 50 cm in front of the stove and at least 30 cm at each side (Figs. 12-14 point
D) (measuring from the combustion chamber door or viewing pane).
No combustible objects (furniture, curtains, decorations, etc.) may be placed within the
area of direct radiant heat of the combustion chamber door or inspection glass. That
distance can be reduced to 40 cm if a fire screen ventilated on both sides is placed
between the fireplace and any combustible objects.
Determining the radiation area
To determine the radiation area of the stove, place a measuring device (yard stick,
measuring tape) on the surface of the front pane and measure the central point of the
stove past the door pillar. There must be no combustible components or components
in need of protection in the resulting angle and within the side clearance.
Minimum distances from nearby building components
The distances indicated in the table below must be observed, according to your stove’s
viewing pane arrangement (see sketches below) and the nature of the mounting walls.
In the stove installation example shown in Fig. 12-14 if dimension B is observed and
dimension E measured on site is less than the value indicated, then it is not necessary
to allow for the radiant area with respect to the side walls. However, if the side wall
is longer than dimension E, it must be decided on site whether this wall needs to be
protected. The position of the radiant area can be altered if necessary by increasing
dimension A or dimension B. The handover inspection of your stove before commission-
ing is performed by the chimney sweep responsible. The chimney sweep can/should
also advise prior to installation about installation conditions on site, and can provide
advice on how to install the stove properly.

2.6 SHUT-OFF DEVICES
Flue gas systems must be created as per the technical rules of the German Association
of Stove and Hot-Air Heating Systems (TROL). Stoves may have a shut-off device in
the vent. These devices must not be self-closing and must not be positioned such as
to prevent or hinder the inspection and cleaning of connecting pipework. The position
of the shut-off device must be visible from the outside, e.g., from the position of the
operating handle. Shut-off devices may only be installed in the exhaust manifold or
collecting pipe, the flue gas pipe stub or the pipeline connecting piece.
2.7 CONNECTING PIECES
Your stove is connected to the chimney by 150 or 160 mm diameter connecting pieces
made from steel sheet at least 2 mm thick. These must comply with DIN 1298 or DIN
EN 1856-2 and they must be connected to the chimney in accordance with DIN 18160
or the regulations that apply in the country concerned.
It is important to ensure that the flue gas pipe takes the shortest possible route upwards
towards the chimney. The number of bends in the flue gas pipe should be kept to a
minimum. Ensure that the flue is stable/robust; where appropriate, the flue may need
to be secured with brackets. If the flue leads through a combustible wall or is located
close to any combustible components, the flue is to be insulated according to the
respective regulations.
The connecting line must always be mounted in such a manner that it is possible
to clean the connecting line at any time. This must be ensured through a sufficient
number of cleaning openings.
If the ambiente a1/a2/a3/a4 RLA is designed to rotate, the connecting piping should
be installed in such a way that the fastening is not compromised. The flue gas pipe
must not turn when the stove rotates. Depending on the information provided by the
flue gas pipe manufacturer, the minimum distance from the chimney connecting piece
to combustible components may increase the distance between the stove and com-
bustible building components. The minimum distances from combustible components
stated in this Manual refer to the stove, and should be adapted if necessary (see „2.5
Fire protection“ on page 19).
In the case of top flue gas routing, please note that a cleaning hatch must be provided
above the flue gas nozzle.

prior to installation.
The connections are labelled and must not be used for other purposes! In
particular, the integral safety device (safety heat exchanger) should not be
used to heat water. an installation template can be downloaded from the
dealer login section. The installation template is only valid in combi-
nation with the flexible connection kit! Alternatively, we can supply a

O is 1041862.
2.8.2 BASIC REQUIREMENTS FOR INSTALLATION
The ambiente a4H
2
O/a6 H
2
O should only be installed in systems with a ther-
mostatic safety device to DIN 4751 or DIN EN 12828. The connecting pipes
to the heating system should always be laid in such a way that they can be
disconnected (e.g. screwed connection).
Before using the stove for the first time, both the heating components (heat-
ing system) and the water components (thermal discharge safety device,
safety heat exchanger) must be filled and vented. After the filling process,
check all hydraulic connections for leaks.
Operation without a water-side connection results in irreparable
damage and invalidates any warranty claims!
A type-tested safety valve (coded H) with a threshold pressure of max. 3.0 bar
should be fitted in the flow pipe immediately next to the a4H
2
O/a6 H
2
O. No
shut-off devices must be integrated into the system between the safety valve
and the ambiente a4H
2
O/a6 H
2
O. This could render the safety device inoperable.
Moreover, all necessary safety devices must be integrated in the entire system
in such a manner that safe operation is ensured. A separate safety valve must
also be installed, if such a safety valve is installed at a different point in the
entire system (comply with TRD 721!).
The installation and operating instructions for the heating components / addi-
tional components included in the system must be read and observed when
installing the stove!
2.8.3 THERMAL DISCHARGE SAFETY DEVICE (TDS)
As the ambiente a4H
2
O/a6 H
2
O heating system cannot be quickly switched
off automatically, the water heat exchanger must be fitted with a thermal
discharge safety device according to DIN 4751 Part 2 or DIN EN 12828. A
safety device (safety heat exchanger) to prevent overheating is integrated into
the ambiente a4H
2
O/a6 H
2
O for this purpose. This safety device must not be
used to heat water.
The thermal discharge safety device is not pre-assembled to protect it during
transport and installation. It will be found inside the firebox at delivery and
should be fitted to the correspondingly labelled connection. After that, the
capillary and adapter should be screwed on to the thermal discharge safety
device. This has been tested and approved for a minimum water throughput
of 900 L/h.
The following instructions must always be complied with for the installation, so
Sample image of an

that the safety device can function:
At the cold water inlet, a flow pressure of at least 2 bar must be available.
This pressure must be constantly ensured. That means, for example, that
a domestic water supply which is dependent on the mains voltage is not
permissible.
A minimum water flow of approx. 900 L/h must be ensured. It must not be
possible to shut off this supply.
It must be ensured that cold water (5-20°) is always available. That does
not include the domestic water supply.
The thermal discharge safety device integrated in the heating system will
open the cold water inlet at a boiler temperature of approx. 95°C!
All safety-relevant components must be integrated in the system in such a
manner that function and leak-tightness can be checked at any time. The
discharge of the thermal discharge safety device must be designed in such a
manner that a check (e.g. via a drain with siphon) can take place at any time.
The cold water pipe should be flushed through before first using the system.
This will flush out any dirt that could interfere with the closing of the thermal
discharge safety device. The instructions and information provided by the
manufacturer of the thermal discharge safety device must be observed.
2.8.4 THERMAL PUMP CONTROL OF THE ambiente a4
H2O / a6 H2O
A thermostatic switch is located in the bottom compartment for optimum
control of the circulating pump. This ensures that the circulating pump will
start up only when the water reaches the specified temperature (>60°C).
It is possible for the pump to be controlled via the boiler control system or
similar devices if the switch-on temperature of the pump is between 60°C
and 68°C.
The maximum contact rating of the factory-fitted pump thermostat is
approx. 16 (4) A with a 250 V AC system.
The thermostat is factory-set to a temperature of approx. 62°C. The circu-
lating pump or the load unit will thus be switched on or off if the temperature
reaches or drops below the specified water temperature of approx. 60°C in
the ambiente a4 H2O’s water heat exchanger. As an option, the temperature
can be adjusted by the installation contractor if circumstances demand. This
is done by removing the top cover, according to the thermostat version. The
temperature range can be altered after removing the cover.
Please note: At water temperatures below 60°C there is a greater risk of
falling below the dew point. This can cause tarry soot to form. Also, cleaning
becomes necessary much more often. We therefore recommend setting the
temperature at which the pump switches on to a minimum of 60°C and a
maximum of 68°C.
2.8.5 ELECTRICAL CONNECTION
The entire electrical installation of the individual components of the heating
system must only be executed by an authorised specialised company. All
electrical installations are to be carried out as per the VDE regulations (e.g.
VDE 0105, VDE 0116, VDE 0100, etc.) and the technical connection condi-
tions of the local power company.
The only work required on the ambiente a4H2O/a6 H2O is the electrical
installation of the thermostat for the temperature riser pump (see page
28) and connection to the domestic electricity supply. The tempera-
ture-resistant connecting lead is approx. 3.0 m long and is already con-
nected up inside the thermostat.

The functioning of the thermostatic switch can be checked before using it
for the first time with hot water (e.g., from a kettle) and a thermometer. Note
that the cover panel has to be removed in order to do this.
2.8.6 INTEGRATION IN A HEATING SYSTEM
Please note: The ambiente a4H2O/a6 H2O must only be installed in an
overall system after detailed planning of the overall heating system in
accordance with the relevant rules of technology and the safety stand-
ards. Proper configuration of the pumps, fittings, pipeline, buffer tank
and the safety components, is the responsibility of the planning firm
and/or of the company in charge of installation. For heating lines, we
recommend a minimum nominal copper pipe diameter of 22 x 1.0 mm,
or 3/4" for steel pipe. For cold water pipes a nominal pipe size (cop-
per pipe) of 15x1.0 and a flow pressure of 2.0 bar are sufficient for
safe operation. Possible variant for integration into a heating system.

However, dimensioning of this pipework must be carried out by the special-
ist company in charge , taking due account of on-site conditions.
The ambiente a4H
2
O/a6 H
2
O can be integrated with reference to Figure 18a
and 18b.
A buffer tank must be included. The buffer tank volume should be
calculated according to BImSchV 1 and 2. This specifies that at least 55
litres of buffer tank volume must be provided per kW water output.
For the ambiente a4H2O that means: 5.7 kW x 55L/kW = 341L.
For the ambiente a6 H2O that means: 4.9 kW x 55L/kW = 269 L.
As this is not a standard size available on the market, the next largest buffer
tank with a capacity of 500 litres should be selected.
The following sample calculation can be helpful for dimensioning the buffer
ambiente a4 H2O
Fig. 18a
ambiente a4 H2O/RLU
Chapter 2
Fig. 18b
ambiente a6 H2O

tank:
The following assumptions have been made:
Size of the buffer tank: 500 l (approx. 500 kg water)
Initial water temperature in buffer tank: 40°C
Final water temperature in buffer tank: 70°C
Temperature differential 30°C (corresponds to 30 K)
No heat is drawn from the tank while it is being heated by the
ambiente a4H2O/a6 H2O!
Thus the heat required to heat 500 litres of water in a tank from 40°C to
70°C is 62,805 kJ (= 62,805 kWs) (disregarding any losses or heat drawn
within the system). That corresponds to approx. 17.4 kWh.
Assuming that the ambiente a4 H2O has an average output of approx. 5.4
kW it will take about 3.2 hours to heat up the entire tank (500 L). This
calculation is based on heating up the entire volume in the tank uniformly.
In an efficiently designed heating system the hot water is stored in layers
in the buffer tank, e.g. in a stratified storage system. That way, hot water is
available after heating up for only a short time and heat is available for use
shortly after circulation starts in the ambiente a4 H2O. Only surplus energy
not needed for heating is then stored in the buffer tank.
On very cold winter days an ambiente a4 H2O may sometimes be in oper-
ation for about 12 hours. The quantity of heat thus produced then corre-
sponds theoretically to 65 kWh. That quantity of heat would heat approx.
1,900 litres (from 40°C to 70°C). As a rule, though, heat is always drawn
off in such a situation and so overheating of the buffer tank (> 90°C) will
not occur.
2.8.7 RETURN FLOW TEMPERATURE RISER
As a general rule, the ambiente a4 H2O/a6 H2O may only be operated with
a return flow temperature riser. In operation, the supply flow temperature
should be at least 65°C and the return temperature at least 60°C. In order
to ensure that these temperatures are guaranteed, a circulation pump /
return flow temperature riser are to be installed in such a way that they
will only start-up when the temperature has reached 62°C. To reduce the
danger of overshooting the dew point, a “controllable” return flow riser
is generally to be installed. This involves capturing the control variable,
which corresponds to the effective return temperature at the entry to the
water heat exchanger, and adjusting it to the desired value.
We recommend the use of the load return riser type LTC 200 from the
company ESBE, which is optionally available, or a comparable return riser.
The use of other solutions (e.g. a four-way mixer) has not proved successful
in practice and is, therefore, not recommended.
We cannot accept any liability nor provide guarantee cover for any mal-
functions (sooting, deposits, etc.) or corrosion damage to the water heat
exchanger or chimney etc. that are due to a missing or non-effective return
riser.
3. OPERATING INSTRUCTIONS
Read these installation and operating instructions through carefully before
installing or operating your stove. Make sure all objects are removed from
the firebox and the ash pan (except for the firebox lining). Ask your special-
ist dealer to explain to you how to operate the stove and how it functions.
National and European standards and local regulations must be observed
when operating this fireplace.

a guard should be fitted to protect the above persons because both the
glass door and the stove cover panels can become very hot in use. Dan-
ger of burn injuries! Never leave these groups of persons unattended
near the stove when a fire is burning or has just been extinguished!
Make these individuals aware of these risks.
Never place any combustible objects on the exposed surfaces or cover
panels of the stove. Never dry washing on the stove. Racks for drying
washing should always be placed outside the radiant area of the stove.
Burning fuel releases thermal energy which heats up the various parts
of the stove, such as the surfaces, the door, the door handle and con-
trol handle, the viewing pane, the flue ducts, etc. Do not attempt to
touch these components without adequate protection (i.e. heat-resistant
gloves).
The enclosed heat protection glove is exclusively designed for
operating the operating handle and the “cold hand”. The glove
is not fire-proof!
The stove must always be operated with the firebox door closed. The
door should always be kept closed, even when the stove is cold. The
only times the door should be opened are when lighting the stove, when
putting on more wood or when cleaning the stove.
Do not modify the stove in any way. In particular, no parts that have not
been expressly approved by Spartherm shall be placed in the firebox
or in the flue gas or combustion air paths. Any modification to the fire-
place without such express approval will void the warranty and operating
permit.
Extractor hoods, ventilators, etc. used at the same time as fireplaces in
the same room or in an adjoining room may interfere with the correct
functioning of the stove (smoke may even escape into the living room).
Such ventilation systems should never be operated at the same time as
the stove unless appropriate precautions are taken (see 2.4.2 Non-room
air sealed operation).
When operating several fireplaces in a single room or linked space,
ensure that sufficient air is available for complete combustion!
This is a temporary fireplace thus, longer continuous burning is not
achieved by piling up the fire repeatedly. Continuous burning without piling
up the fire in-between cannot be achieved even through withdrawal of
the combustion air and is not permitted. A longer heating period can be
achieved by the appropriate addition of more fuel.
Do not place any combustible materials in the lower compartment of the
stove cover.
For a4 H2O /a4 H2O RLU only: Due to the low flue gas temperatures, the
chimney system must not be sensitive to moisture.

3.2 S-THERMATIK MINI
Supply voltage: 230V AC / 24V DC
(via wall plug transformer)
Power consumption during operation approx. 10 VA
Power consumption in "Stand-by": ca. 6 VA
Protection class: III (safety extra-low voltage)
Degree of protection: IP 50
The S-Thermatik Mini combustion control is pre-set to your stove used
ex-factory. Changes to the control parameters must only be carried out by
an installer / stove fitter or the customer services. Please note the service
instructions supplied!
3.2.1 INITIAL COMMISSIONING OF THE S-THERMATIK
MINI
In order to guarantee an optimum and trouble-free operation of the fire-
place, the door contact switch must be kept free from dirt and grime.
Before opening the combustion chamber door, make sure that the selector
switch points to AUTOMATIC when the combustion air control is switched
on. In automatic mode the control is activated from the stand-by by open-
ing the combustion chamber door. Now the actuator motor runs the dosing
facility for the combustion air to the position OPEN. The firewood is put in
place and ignited (also see 4. Combustion), the combustion chamber door
is closed. The combustion air is set and controlled automatically via the
actuator motor on the basis of the flue gas temperature measured.
If the flue gas temperature is still below 50°C after 10 minutes (after closing
the combustion chamber door), the combustion air is closed again by the
control without further signals. The air adjustment lever moves to the left.
Heat-up error: The flue gas temperature increases above 50°C but the pre-
set minimum temperature for starting the control is not reached: If the
flue gas temperature drops below 50°C again, the combustion air supply
is closed after another 15 minutes An audible signal sounds. Reasons for a
heat-up error could be that not enough, too much, too large or fuel that is
too moist has been added, or the water heat exchanger pipes are blocked.
If there is a heat-up error and the flue gas temperature continues to
increase, the combustion air supply is throttled depending on the flue gas
temperature. Thus, the primary air (flows via the ash grate in the firebox) is
closed first and then the secondary air is reduced (differential combustion
air setting). In doing so, the combustion air lever moves from the right
approximately to the middle in steps. In the further course of combustion
and when the flue gas temperature drops, the combustion air quantity is
reduced further.
In doing so, the combustion air lever moves from the middle further to the
left.
Once the flue gas temperature has dropped far enough so that only embers
are in the combustion chamber, you are prompted to add fuel by an audible
tone. If the audible tone is not desired, this can be switched off. After the
signal, you have approx. 10 minutes to add more fuel without having to use a
firelighter. If fuel is added and the combustion chamber door is opened, the
control opens the combustion air supply completely to 100% again. In doing
so, the air control lever moves back completely to the right again.
If no fuel is added after the flue gas temperature has dropped even further,
the combustion air is closed to a minimum. After the period of maintaining
Chapter 3
31
the embers, the combustion chamber can be ventilated by opening the com-
bustion air for three minutes. This function allows the ember bed to reduce
further. After the venting process, the combustion air
is closed completely (0%) and the control shifts to standby mode (control
display off).
The correct operation of the S-Thermatik mini combustion control is indi-
cated by a maintenance-free signal lamp that is mounted behind the fire
symbol in the bottom flap and is displayed by the moving air adjustment
lever.
If the air adjustment lever does not move after opening the combus-
tion chamber door, the S-Thermatik Mini must be switched to man-
ual mode by hand using the mechanical unlocking device (rocker
switch). The selector switch is located in the supply air box and can be
seen when the front cover of the stove is opened. The combustion air
can be adjusted by hand via the air adjustment lever. Further details
on manual setting can be found in 4.1.1 Combustion air regulation.
The fireplace insert must never be put into operation with the
combustion air supply (combustion air lever all the way to the left)
closed!
Heat-up errors and the prompt for adding fuel are indicated by an audible
signal. The acoustic signal can be switched off using the rocker switched
mounted on the control housing.
3.2.2 FUNCTIONAL TESTING OF THE S-THERMATIK MINI
When commissioning the control each time (inserting the wall plug transformer
into the socket or when shifting the selector switch from manual to automatic),
this carries out a self test when the combustion chamber door is closed. In doing
so, the air adjustment lever moves from the left to the right and after a rest period
of max. 1 minute, back to the left again. The air adjustment lever only moves to
the left if the door contact and the flue gas temperature sensor are functional. The
self test should be carried out when the combustion chamber is cold. When the
combustion chamber is hot, the air adjustment lever does not move completely to
the left, it takes the respective position according to the current flue gas tempera-
ture. After this self test, the control shifts to stand-by mode with cold stoves and
"waits" until the combustion chamber door is opened.
Perform self-test:
Move the selector switch to manual
Insert the wall plug transformer into the socket
Position the air adjustment lever in the middle by hand (about 50%)
Move the selector switch to automatic
Chapter 3

The LED must light up and air adjustment lever must move to the right.
If the lever firstly moves to the left, swap over the white and red wires on the
control.
The air adjustment lever must move to the right after max. 1 minute.
If not, swap the blue and brown wires on the control with each other and
repeat the self test
Open the combustion chamber door, the air control lever must move to the
right.
End of the self test. Now you can fire-up the oven. If no fire is started, approx.
10 minutes after closing the door, the air adjustment lever moves back to the
left to 0%.
3.3 FUNCTIONING OF THE ROTARY BASE
A rotary base can only be used with the ambiente a1/a2/a3/a4 models with top
flue gas connection and must be specified when ordering. The base enables the
stove to be rotated 180°, i.e. 90° to the left and 90° to the right (Fig. 20a).

3.4 RATING PLATE
The rating plate can be found on your warranty certificate and on the
rear of your stove below the ash pan or in the lower flap. It includes
technical data and information. The rating plate must not be removed
as it confirms the testing of the device and is required for the accept-
ance procedure and annual inspections by the chimney sweep.

The water heat exchanger is operated using the H

O Hebel on the back of the
stove. This switches between the lighting-up/adding more fuel position and
the combustion position. The lever does not have an intermediate position.
Lighting up or combustion phase (Fig. 21 B) The lever is right at the bot-
tom. The flue gas is not routed through the heat exchanger. That allows the
chimney draught to develop as quickly and effectively as possible.
Combustion position (Fig. 21 A) The lever is right at
the top. All the flue gas will now be routed via the
water heat exchanger. Wait for the stove to heat
up fully, the fuel to catch light and embers to form
before moving the lever to this position. That nor-
mally takes about 15-20 minutes.

4.1 INITIAL COMMISSIONING
The stove must be assembled and installed by a specialist contractor. The
initial commissioning must only be executed by an expert employee of the
installation company. A certificate confirming proper installation and proper
adjustment / function of all control components and safety components
must be given to the owner / operator of the system (see „9.1 Commission-
ing protocol ambiente a1/a2/a3/a4/a5/a6/a7/a8“ on page 53).
When first putting your appliance into service, only start a moderate fire.
This enables you to avoid cracks in the firebox lining (which may still contain
residual humidity before the first firing). Slowly increase the heating power
to about 30% above nominal heat output by setting the fire 3 to 5 times to
give the corrosion coating applied to the surfaces time to 'burn in' properly
During this process, the paint can become slightly soft, do not place any
objects on the stove and do not touch the appliance. During this burning-in
process, an unpleasant yet harmless odour (sometimes accompanied by
the build-up of smoke) may be given off. It is therefore important to ensure
that the room is well ventilated during the burning-in process. Open all the
doors and windows to let fresh air in.
Please note that slight expansion or contraction noises may be heard as the
stove heats up or cools down. Such noises occur as the material expands at
high temperatures, and are not a cause for concern.
4.1.1 INITIAL COMMISSIONING OF THE ambiente
a4 H2O/a6 H2O
Commissioning must not take place until all the necessary components have
been connected up, all necessary safety devices have been integrated and
are operational, the water heat exchanger has been filled and the system has
been vented. It is not permissible to operate the system without water, when
only partly filled or with safety devices that are not operational. It may be
necessary to vent the water heat exchanger several times at commissioning.
The operator must also be given detailed instructions on the operation,
functioning and maintenance of the entire system including all additional
components. In addition, the measures for maintaining safe operation of the
system must be communicated to the owner. Briefing must be documented
in the commissioning protocol (see point 9 Commissioning protocol) The
installation and operating instructions must always be kept in the vicinity of
the ambiente a4 H2O/a6 H2O where they can be easily accessed.
Before commissioning it is important to check whether any objects are still
inside the firebox or in the ash pan. If so, remove them.
The stove is supplied with a ceramic fibre mat 3-5 mm thick on top of the
deflector plate of the firebox lining. This is needed to soak up any conden-
sate occurring the first three times the stove is lit. Before lighting the stove,
check that the mat is lying snugly on top of the chamotte deflector plate.
If the mat is not in position, condensate can drip on to the firebox lining,
leaving permanent stains. The fibre mat can be removed after the stove has
been lit 2 or 3 times.
Also, dirty condensate may leak from the bottom of the firebox and may
soil or damage the floor underneath the stove. An absorbent material should
therefore be placed under the stove the first few times it is used, until there
is no more condensate leakage.
Please note that slight expansion or contraction noises may be heard as the
stove heats up or cools down. Such noises occur as the material expands at
high temperatures, and are not a cause for concern.

4.2 COMBUSTION AIR REGULATION
Combustion air is regulated across an infinitely variable range using the
actuating lever located below the door (Fig. 23). Adjustment takes place
with the combustion chamber door closed!
Air supply open (A): For heating or for adding more firewood, move the
actuating lever fully to the right. The firebox will now be supplied with the
maximum amount of air for primary and for secondary combustion purposes.
On the ambiente a5 the air adjustment lever should be moved upwards. The
lever is located on the rear of the stove.
Throttled combustion (B): Adjustment lever roughly in the middle position.
The primary air supply is now closed off, so that the fire is not supplied
with too much air. The secondary air flows over the ceramic glass pane via
the airwash which minimises sooting-up of the glass. This is the normal
position during combustion. The exact position depends on local conditions
and can be adjusted by the operator according to how the stove is burning.
Air supply closed (C): Adjustment lever at the far left. In this position, no
combustion air is supplied to the firebox chamber of the stove. However,
do not shut down the air supply altogether until the fuel has burned away
completely. If the stove is not in operation, you should always close the air
supply.
On the ambiente a5 the air adjustment lever should be moved downwards.
The lever is located on the rear of the stove.

4.3 HEATING UP / BURNING
Lighting your stove is very easy if you follow the instructions below. We recom-
mend combustion as above as this produces fewer emissions and smoke and thus
causes less soiling of the firebox and panes.
1. The stove must not be operated unless the firebox lining is correctly
installed.
2. Move the air adjustment lever to the firing up position (A) and open the
combustion chamber door (swivel open).
3. Place two split logs in the firebox and build a pile of kindling (soft wood
is best).
4. Place some standard firelighters on the pile to help light the fire. (Paper
is not recommended as it burns away too quickly and causes flying ash)
5. Never use spirit, petrol, oil or any other highly flammable liquids.
6. Now light the fire by lighting the
firelighters, and leave the combustion
chamber door open about 3-5 cm. The
fire should soon start burning strongly
and brightly.
7. Once the kindling is well alight you
can add some small hardwood split
logs or larger softwood logs, piling
them up on top.
8. Close the door once the logs are burning well. The air adjustment lever
remains in the far right position (air supply open) and it should stay in
that position for at least another 20-30 minutes to get the stove up to
operating temperature.
9. More information about how much wood to put on the fire can be found
in section Hourly wood consumption rate (4.2.2 Hourly wood consump-
tion rate).
10. Once all the wood has fully burned away, more wood can be added as
required (hardwood is ideal).
11. According to the weather conditions, move the air adjustment lever more
or less to the centre position. This always depends on experience and on
prevailing conditions on location.
12. Do not open the door forcefully or gases may enter your living room
through a suddenly produced negative pressure. At first, open the door
slowly and only a crack.
13. Putting fresh firewood onto hot embers you prevent the possible release
of smoke when the door is opened.
14. Never repeatedly put more than the recommended amount of wood onto
the fire.
15. If your chimney is drawing too strongly, the fire will blaze up even with
only a minimal secondary air supply. Move the air adjustment lever
slightly to find the best position for controlled combustion. Please
note: the further you slide the air controller towards 'Air supply closed',
the less air you are directing into the firebox. Ensure that you do not
restrict the airflow too far, causing the fire to go out (6.7. Controlling
heat output).
4.3.1 ADDING WOOD / END OF THE COMBUSTION
PROCESS
Wait for the wood to burn down to embers before adding more wood.
1. Move the air supply to the fully open position (position A)
2. Open the combustion chamber door very slowly (use the protective glove) to
avoid turbulence which can encourage smoke to leak out.
3. Place the firewood on the embers (bark facing upwards, cut ends to either
side. Make sure the air supply is open. The embers must not be starved of air).
4. Close the combustion chamber door (use protective glove!)
Chapter 4
37
5. Leave the air adjustment lever in the fully open position (far right) for about 2
to 5 minutes. Wait for all the new wood to catch light before altering the air
adjustment lever position again.
6. Then move the lever to the middle
position B.
The end of the burning process is achieved
when the wood has burned completely, and
no smoldering or incomplete combustion
can occur. Now the lever can be closed.
Always leave the air adjustment lever in the
closed position C when the stove is not in
use (see Fig. 23).
4.3.2 HOURLY WOOD CONSUMPTION RATE
In order to avoid damage due to over-heating (discolouration of the steel,
deformation, etc.) and to guarantee optimum performance over the lifetime
of the appliance, ensure that the stove is fuelled in the proper manner.
To prevent any risk of over-heating, make sure that the maximum heating
capacity is never exceeded.
The proper amount of wood feed per hour can be found in
„2.2 Technical data“ on page 6. The individual wood logs should be no
more than approx. 25 cm in circumference!
Please note: Increasing the wood feed beyond this amount may result in
overheating and damage to the stove. Wood pellets (briquettes) have a
higher heat output than hardwood. Hourly consumption when using pellets
should therefore be at least 20% lower than when burning logs.
The warranty will be voided in cases of damage due to overheating (exces-
sive hourly wood consumption).
4.4 CONTROLLING HEAT OUTPUT
Heat output is controlled by regulating the amount of fuel added. Do not try
to slow down combustion excessively by reducing the flow of inlet air. When
heating with wood, this causes incomplete combustion and therefore wastes
fuel and causes unnecessary levels of environmental pollution because
wood releases gases even if no flames are produced. This also increases
the soot deposits on the viewing panes! What is more, there is the risk of
deflagration (explosive ignition of the flue gases).
Ensure that the firebox door is always firmly closed to prevent combustion
being accelerated by the uncontrolled inflow of air. Your stove’s output also
depends on the chimney draught. This draught can be adversely affected
by the cross section of the chimney, or by environmental factors such as
strong winds etc.
4.5 ROOM HEATING CAPACITY / INDOOR CLIMATE
The room heating capability used to be quoted in accordance with the DIN
18893 standard (most recent edition being August 1987) so is no longer a
meaningful indicator for modern houses constructed after 1990. However,
the old room heating capacity value may still be of interest as a comparative
value or for use in the case of older structures pre-dating the 1977 thermal
insulation standard.
Chapter 4
38
burn away faster (with more flames). This will help to stabilise the chimney
draught To avoid resistance in the firebed, it should be carefully raked at
frequent intervals to remove the ash. The air supply can be reduced slightly
(middle position B) when the chimney draught has stabilised.
5. FUEL
Stoves may only be operated using fuels that correspond to the 1st BlmSchV
regulations. Only firewood (recommended residual moisture 20% or less) or
wood pellets according to DIN 51731 are permissible for use in stoves
Incidentally: A measuring device for determining the moisture of firewood does
not cost very much and quickly pays off.
Do not use any other fuels!
It follows from this that it is not permitted to burn:
Varnished or plastic-coated wood
Chipboard or wood that has been treated with wood preservatives
Wood originating from Europool palettes
Rubbish, household waste, old clothes
Paper, paper briquettes, cardboard
Coal, coal briquettes, brown coal
Damp wood (residual humidity > 20%)
Plastics / foam material of any sort
Any solid or liquid materials that contain no wood
It is prohibited to burn these or other inappropriate materials in your stove.
When burning other materials than the permitted fuels, firewood or wood bri-
quettes defined in DIN 51713, toxic gases can be formed that have an adverse
effect on the combustion process, and that may even cause explosions.

Considerably bigger rooms can be heated with modern thermal insulation.
Direct room heating not including water heating
Precise descriptions of the terms 'favourable', 'less favourable' and 'unfa-
vourable' can be found in DIN 18893. Simply put, ‘favourable’ describes a
situation where the room has only one external wall and otherwise mainly
adjoins heated internal rooms, whereas ‘unfavourable’ refers to a room with
two external walls and adjoining unheated rooms.
The values indicated above refer to structures pre-dating the 1977 ther-
mal insulation standard. They represent a simplification which is valid for
room sizes up to 200 m³. DIN 18893 standard recommended a calcula-
tion according to DIN 4701 for rooms larger than 200 m³. Nowadays, an
estimate according to TR-OL is preferable or, in particular, the calculation
should be based on DIN 12831.
4.6 HEATING IN THE TRANSITIONAL PERIOD / UNFA-
VOURABLE WEATHER CONDITIONS
In the transitional period, when the outside temperature is above approx.
15°C, or during unfavourable weather conditions (down winds, etc.), disrup-
tion to the chimney draught may occur due to sudden rises in temperature,
with the result that the flue gases are not completely extracted. In these
circumstances a smaller amount of fuel should be placed in the stove and
the air adjustment lever should be moved to the maximum position (see „4.2
Combustion air regulation“ on page 35). The fuel in the stove will then
Chapters 4/5
39
Operating stoves with other than the approved fuels renders the warranty
invalid!
Use small pieces of wood to get the fire going. For firewood, use only split
wood that is not thicker than about 8 cm at its thickest point. The optimum
length of firewood is approximately 25 cm. Please do not add too much wood
at one time. Instead, it is better to add smaller quantities of wood at regular
intervals. When adding wood to the fire, the embers must not be completely
covered.
5.1 CO2 NEUTRALITY
Wood only releases as much carbon dioxide as it collected and trapped from
the air as a tree. It is irrelevant in this case whether the wood is burned or
rots in the forest – the carbon dioxide released always remains the same. A
closed natural carbon dioxide cycle is produced.
Conclusion: When burning wood, nature remains in balance. German Law
legislates for the sustainable management of forests. This obligation leads to
an increase in timber volumes, since the average increase in timber is 40%
greater than the amount of firewood and timber that is consumed.
5.1.1 WOOD STOR AG E
In general, it is recommended to store firewood for approx. 2-3 years, the
wood should be protected from dampness and well ventilated (e.g. under a
roof overhang on a side of the building protected from the weather). Wood
with moisture content < 20% will be achieved significantly quicker with opti-
mal storage.
Therefore, you should store your firewood already chopped because the bark
can prevent the moisture escaping from the wood. You should leave a distance
the width of a hand between the logs for good ventilation so that the air can
circulate properly and the moisture escaping from the wood can be taken away
by the air. A distance to the floor of approx. 20-30 cm should be maintained
underneath the stack of wood. Renewed absorption of moisture due to precip-
itation (e.g. rain or snow) should be avoided. Storing wood in garages, under
plastic sheets or in poorly ventilated cellars is not recommended because the
moisture present in the wood cannot escape properly.
5.2 YOUR CONTRIBUTION TO ENVIRONMENTAL
PROTECTION
Whether or not your stove burns in an environmentally-friendly way is very
much dependent on the choice of fuel and the manner, in which the fire is
operated. The following tips should help you operate your stove with mini-
mum harm to the environment:
Use as little wood containing resin as possible (fir, pine, spruce). These
types of wood cause soot to form on the window of your stove more
rapidly, and also cause more sparks. Therefore, for safety reasons, only
use deciduous woods (birch, beech, oak, fruit tree timber).
Chapter 5
40
Adapt the amounts of wood you add to the fire to suit your heating
requirements.
You can check that combustion in your stove is clean and relatively free of
pollutants in the following way:
The ash should be white. If the ash is dark, this indicates the presence of
residual carbon, which in turn indicates incomplete combustion.
The flue gas from the chimney stack should be virtually invisible (less
smoke means improved combustion).
The firebox lining in your stove should be bright after combustion, not
sooty.
Note: The fireplace must not be used as a waste incinerator! Furthermore,
this is a temporary fireplace thus, longer continuous burning is not achieved
by piling up the fire repeatedly. Continuous burning without piling up the fire
in-between cannot be achieved even through withdrawal of the combustion
air and is not permitted.
6. CLEANING AND CARE
The stove may only be cleaned when cold. Bear in mind that through clean-
ing, soiling of the setup room and the clothing worn can occur. We recom-
mend that you protect the area around the combustion chamber opening
against soiling with foil or with a cloth and that you also wear work clothes.
All the disassembled parts are to be assembled again after cleaning.
6.1 CLEANING OF FIREBOX / CLADDING PARTS
The stove, firebox, smoke collecting chamber with heating gas diverter,
combustion air system and the connecting pieces for the chimney must
be examined for deposits at regular intervals annually and possibly also
during and after each heating season and after cleaning the chimney
and, if necessary, cleaned (consult your stove dealer or local chimney
sweep). Deposits are to be removed using a hand brush and/or ash vac-
uum (specialist dealer). The chimney must be cleaned at regular inter-
vals by the chimney sweep. Furthermore, the stove should be inspected
annually by a specialist.
Flue gas diverter: Above the firebox, in the flue gas manifold, there is
also a flue gas diverter. This must be cleaned regularly. To this end, the
flue gas diverter can be removed. It must be lifted up, tilted and removed
through the firebox. Deposits on the diverter can be simply removed
using a handbrush.
Ash removal: Your stove is suitable for the combustion of dry wood which
should ideally burn in its own ash. Should, however, you prefer to remove
the ash from the firebox, open the stove door. Lift the grates out of the
firebox and, using a standard companion set, brush the ash into the ash
drawer below. Remove the drawer and dispose of the contents properly.
If your stove does not have an ash grate, the ash is to be removed from
the firebox using a companion set.
Note that the ash can keep the embers hot for up to 24 hours and longer!
Cleaning the ceramic glass pane: You can easily clean the glass panel
with a commercially available cleaning agent for fireplace glass.
Use dry cloth to wipe. No scouring.
Please do avoid that excess cleaning agent enters between door
frame and glass panel. This might cause the hardening of the sealing
compound between glass panel and door frame. A hardened sealing
Chapters 5/6
41
compound might lead to damages of door and glass.
Suitable cleaning agents for fireplace glass are available at your spe-
cialist dealer.
Painted surfaces and the cladding parts can be cleaned with a moist
cloth (do not use a microfibre cloth!) without cleaning agents.
Glass surfaces can be cleaned with a standard glass cleaner and a soft
cloth (do not use a microfibre cloth!) without cleaning agents.
Stainless steel surfaces can be cleaned with standard stainless steel
cleaning agents! Only use in the direction of the finish!
Natural stone surfaces can be cleaned with a wet cloth or suitable stand-
ard cleaning agents!
Ceramic surfaces can be cleaned with a wet cloth or suitable standard
cleaning agents!
Remove any dust on and below the stove regularly during the heating season
as dust particles can burn or char. This can cause dirt and odours in the room
and on the furnishings where the fire is installed.
6.2 FIREBOX LINING
In the heating-up phase it is normal for the lining to have a dark coating. After
reaching the operating temperature, the firebox lining burns freely. Cracks are
not grounds for a justified complaint. The lining is subjected to very high loads.
A tension or expansion crack is not a matter for concern nor is it a functional
fault. Nevertheless, broken and dislodged bits of firebox lining must be replaced.
If replacement chamotte is required, you can order this from your stove fitter

6.3 CHIMNEY FIRE
When burning wood (especially softwood), sparks can often be transferred
from the fireplace to the chimney This may ignite the soot in the chimney.
This rarely happens if the chimney is cleaned regularly by the chimney
sweep. The chimney catches fire. This can be recognized by flames that
blaze from the chimney opening, excessively flying sparks, smoke and
odours, as well as the chimney walls becoming progressively hotter. It
is important to act properly in such cases. You can alert the fire brigade
by dialling 999 (or 112 in Germany). The chimney sweep must also be
informed. Combustible objects should be located away from the chimney.

ambiente a8 Fig. 28
Chapter 6
44
Attention: Do not attempt to extinguish the fire with water before the fire
brigade arrives on the scene. Temperatures in a chimney fire can reach up
to 1300°C. Extinguishing water would immediately create steam. A 10-litre
bucket of water yields 17 cubic meters of steam. The enormous pressure
created as a result could cause the chimney to disintegrate. Once the chim-
ney fire has burnt itself out, the chimney must be examined by a specialist
for cracks or leakages and, if required, repaired accordingly.
6.4 MAINTENANCE
The door seal must be checked at regular intervals! If necessary replace the
seal (in the case of wear, cracks etc.).
The firebox lining is made of natural products and must thus be checked at
regular intervals. It is made of natural products that expand and contract
with every heating process. This can cause cracks to appear. The firebox lin-
ing will remain fully functional provided it is still in position and not broken.
A crack in the chamotte stone is thus not cause for complaint.
For proper functioning, annual maintenance of the stove by a specialist
(preferably before the heating season) is essential!
For non-room air sealed stoves the following also applies:
A proper door seal is of elementary importance for stoves with non-room air
sealed operation. Check the seal for visual features (pressure, wear, dents)
at least once per heating season and change immediately if damaged.
The fireplace must never be modified! Only original spare parts that have
been approved by the manufacturer may be used! If you have any questions,
please contact your specialist dealer.
6.4.1 LUBRICATION GUIDE FOR DOOR LOCKS WITH
SMARTCLOSE
Stove and fireplace inserts with SmartClose door locking mechanisms must
be lubricated at regular intervals to assure problem-free operation (once
per heating season).
For this purpose,
the scope of delivery of each fireplace
includes a tube of special stove lubri-
cation compound. This lubricating
compound is applied to facilitate ease
of movement of heavy fire doors, and
to prevent noise caused by opening
and closing the fire doors. The lubri-
cating compound must be applied at
least once a year to the spring connection
on the SmartClose and its associated roller. With fireplaces used frequently
or very frequently, it may be
necessary to shorten this
lubrication interval. Depend-
ing on the stove or type of
fireplace insert, the door lock
springs may be located below
and/or above or to the side
of the combustion chamber
door. In order to lubricate the
lock, you may use a standard
cotton swab as an aid.
To apply the lubricant
Chapter 6
Fig. 29a
Fig. 29b
45
compound, proceed as follows:
Open and secure the combustion chamber door. Apply a little lubricant
compound to the cotton swab and use it to coat the spring support (see Fig.
29b) on the door lock. Turn the locating roller on the body of the stove by
hand during this application process (see Fig. 29c).. Open and close the fire
door a few times and, if nec-
essary, apply the lubricant
compound once again.
Caution: Ensure that no
copper lubricant com-
pound makes contact
with cladding parts or
similar items! Remove
dirt and grime straightaway
with a cotton cloth. Never operate the equipment during intervening
periods.
6.4.2 MAINTENANCE OF THE WATER HEAT EXCHANGER
OF THE AMBIENTE A4 H2O / A6 H2O
The ambiente a4 H2O/a6 H2O must be maintained. The stove can only func-
tion at full efficiency if it is regularly and properly serviced. The technical
heating inspection and checking of all safety devices (thermal discharge
safety device etc.) is required yearly before the heating season. This
check must only be executed by a specialised company. We recommend
that you conclude a maintenance contract with your specialised company.
This guarantees that the annual safety inspection is reliably performed
before the heating season. The executed yearly safety inspections must be
documented!
6.4.3 VENTING THE WATER HEAT EXCHANGER OF
THE AMBIENTE A4 H2O / a6 H2O
The vent is located in the heating connection area, in the lower compart-
ment. The vent must be opened with a bleed key. A suitable container or
large towel should be kept at the ready to collect any water which leaks out.
A small tube can be attached to the vent. Upon opening the valve, water
firstly comes out of the vent line followed by air a few seconds later. Once
the air has escaped, the valve should be kept fully open for a further five
seconds.
The system must be vented:
Before and during initial commissioning.
Daily over the course of the following weeks until no more air escapes.
If sounds (air bubbles) can be heard in the heat exchanger.
If the pressure of the domestic water supply has been adjusted.
6.5 CLEANING THE WATER HEAT EXCHANGER OF THE
AMBIENTE a4 H
2
O / a6 H
2

Cleaning the water heat exchanger is absolutely necessary. Regularly and prop-
erly servicing allows the stove to function at full efficiency. Cleaning must always
be executed in cooled-down status!
Because the water heat exchanger directly cools down the flue gases and this
unavoidably results in deposits on the surfaces of the heat exchanger, these
surfaces must be cleaned with the integrated cleaning system on a regular basis.
The water heat exchanger should be cleaned once daily, or each time the
ash drawer is emptied, once it has cooled down. Regular operation of the
Chapter 6
Fig. 29c
46
cleaning system prevents the system from seizing.
If after the first cleaning operations, it is noticeable that little to no deposits were
removed, this means that you can extend the cleaning interval for your operating
conditions. If, on the other hand, heavy deposits are found during cleaning, then
cleaning must be carried out more frequently and the cleaning interval must be
shortened.
If the cleaning mechanism can only be operated with increased force after pro-
longed operation, this is an indication of disproportionate contamination of the
water heat exchanger. In this case, please check the moisture content of the fuel
(< 20 %) and make sure that the heating integration works properly (min return
temperature > 62°C). If you are not sure that these conditions have been com-
plied with, please contact your installer for heating installations. When inserting
the operating handle, ensure that it does not hit the painted edges! The soot
discharged by cleaning automatically falls onto the baffle plate in the combustion
chamber and should be cleaned off from there at least 2 times per season.
Cleaning process for a4 H
2
O:
The operating handle is included in delivery and must be inserted in the 20 mm
hole on the top left side of the unit when cleaning. Then actuate the operating
handle about 5 times up to the stop (20° angle of rotation). When inserting the
operating handle, ensure that the it does not hit the painted edges of the stove!
Cleaning process as of a6 H

The ambient temperature is above
about 15°C. The weather conditions
are unfavourable (e.g. fog). These
weather conditions occur most
frequently in spring and fall.
4.6 Fill the fireplace with a small amount of fuel and light it with the damper fully open (max. air flow).
There is a temperature inversion.
That means that the upper layers of

The combustion air controller is not
fully opened. 4.2 Move the air actuating lever into its far right-hand position.
The external combustion air line is
not free. 2.4.3 Clean the combustion air line.
Combustion air is too heavily restrict-
ed. This means that soot accumulates
quickly, within just half an hour. (it is
normal for operation of the system to
make the fireplace unit progressively
more dirty. When driving, a car win-
dow becomes dirty, too!)
-Check the position of the air lever and, if necessary, open up the combustion air flow rate fully to bring the
fireplace unit up to operating temperature.
The seating of a gasket is not perfect. - Check all seals, e.g. open the fire door and press the seal fully into the door profile.
The wood is not dry enough. 5. Measure the residual humidity in the wood used with a humidity detector. The recommended residual humidity
is 20% or less.
Not enough wood has been added. (an
insufficient amount of wood can result
in temperatures in the stove not being
high enough).
4.3.2 The proper amount of wood feed per hour for your tiled stove can be found in the technical data.
The chimney draught is too strong /
too weak. -Observe the situation. The draught characteristics can be affected by the prevailing weather pattern. If the glass
continues to soot up badly, inform your chimney sweep.

The wood too thick. 5.
Use small-sized timber to light the fire. For firewood, use only split wood that is not thicker than about 8 cm
at its thickest point. The optimum length of firewood is approximately 20 - 25 cm. In the case of prolonged
heating, do not add too much wood. Instead, it is better to add smaller quantities of wood.
A sufficient air supply is not assured. 4.2. For lighting the fire or adding more firewood, move the actuating lever fully to the right.
The ambient temperature is above

7. TROUBLESHOOTING
7.1 WATER HEAT EXCHANGER OF THE A4 H2O
Problem description Cause / solution:
Thermal discharge safety
device trips constantly (con-
stant water outflow through
the discharge).
The water heat exchanger
cannot dissipate heat to the
heating system.
The buffer tank is "full".
Warning: Remove heat from the heat storage mass
Check function and settings of the pump thermostat and the return
riser.
Set the pump one level higher (higher flow rate).
Circulation pump does not run. Is the power connection defective?
Vent the stove.
Check system pressure.
When initially used, water
leaks out of the base of the
system.
If the stove and heating installations are tested under pressure after
assembly, the water which leaks out is condensation from the fuel
and firebox lining. If more than 0.2 litres of water accumulate, the
heating system pressure must be checked.
Gurgling sounds in the
water heat exchanger. Air in
the system.
Check system pressure.
Ventilate system via the vent. For newly filled or topped up systems
it takes some time for all the air to collect. Often ventilating once
does not suffice.
Thermal discharge safety
device drips.
Flush the thermal discharge safety device by activating the red
button on the fitting.
Check the seat of the connection seals and the piston (see the
instructions on the thermal discharge safety device).
If necessary, integrate filter in the system upstream of the discharge
safety device (pay attention to the minimum flow rate!)
Radiators do not warm up.
Radiators which are not in
the installation room are
cold.
Close radiator thermostats when the set room temperature is
reached. The convection heat of the fireplace is distributed in the
air composite.
Depending on the configuration the heating system is sluggish. It
takes some time until the heating system dissipates its heat.
Have the heating system hydraulically calibrated.
Check heating circuit pump for function.
Increase fuel feed rate.
Problem description Cause / solution:
Increasing and faster con-
tamination of the firebox
lining and of the glass
ceramics.
The firebox lining no longer
burns free.
Fire can only be ignited with
difficulty
Remove deposits in the heat exchanger and in the connecting line
to the chimney.
Check that the pump thermostat is functioning correctly.
Pay attention to correct firing, wood feed quantity, wood moisture
content < 20%.
Correct the position of the air adjustment lever.
Check that the return riser is functioning correctly.
Rapid soiling of the flue
gas lines in the water heat
exchanger. Insufficient com-
bustion performance.
Check return riser.
Pay attention to correct firing, wood feed quantity, wood moisture
content < 20%.
Remove deposits in the heat exchanger and in the connecting line
to the chimney.
Check that the pump thermostat is functioning correctly.
