2-INSTALLATION
The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case,
always observe the domestic regulations in force.
PELLETS
Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The
compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or
binders.
The market oers dierent types of pellets with characteristics that vary according to the wood mixtures used. The most common
diameter on the market is 6 mm (although 8 mm diameter is available too) with a length, on average, of between 3 and 40 mm. A good
quality pellet has a density of between 600 and 750 or more kg/metres cubed and a water content that accounts for 5 to 8% of its weight.
Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner
combustion than that of fossil fuels.
Good-quality wood has a caloric value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets is 4.9
kW/kg. To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually supplied in 15 kg
bags, therefore, storing them is very convenient.
Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.
The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber must
be cleaned.
The main quality certications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2
according to ISO 17225-2 (ex EN 14961). These certications include, for example, ENPlus, DINplus, Ö-Norm M7135, and in particular,
guarantee the following characteristics:
• caloric value: 4.6 ÷ 5.3 kWh/kg.
• Moisture content: ≤ 10% of the weight.
• Percentage of ash: max 1.2% of the weight (A1 less than 0.7%).
• Diameter: 6±1/8±1 mm.
• Length: 3÷40 mm.
• Content: 100% untreated wood without the addition of binding substances (max 5% bark).
• Packaging: in sacks made from ecologically compatible or biologically decomposing material.
The company strongly recommends using certied fuel for its products (ENplus, DINplus, Ö-Norm M7135).
Poor quality pellets or others that do not comply with the characteristics specied previously may compromise the
operation of your product and can therefore render the guarantee and product liability invalid.

FOREWORD
The installation position must be chosen according to the room, to the smoke extraction system, to the chimney ue. Check with local
authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the
ue or the chimney cap. The manufacturer declines all responsibility in the event of installations that do not comply with the laws in
force, incorrect room air exchange, electrical connection non-compliant with the standards and inappropriate use of the appliance. The
installation must be carried out by a qualied technician, who must issue a declaration of conformity of the system to the purchaser and
will assume full responsibility for nal installation and consequent good operation of the product.
In particular one must ensure that:
• there is a suitable combustion air inlet and smoke outlet in compliance with the type of product installed
• other stoves or devices installed do not cause depression in the room where the product is installed (for sealed appliances only, a
maximum of 15 Pa of depression in the room is allowed)
• when the product is switched on there is no reux of smoke in the room
• fumes extraction takes place in total safety (sizing, smoke seal, distances from ammable materials..).
We especially recommend to check the data tags of the ue for the safety distances that must be observed in presence
of combustible materials and the type of insulating material to be used. These indications must be followed strictly to
prevent serious harm to people and the integrity of the home. The installation of the appliance must ensure easy access to
clean the appliance itself, the smoke outlet pipes and the ue. It is forbidden to install the stove in rooms with a re hazard.
Installation in studio ats, bedrooms and bathrooms is only allowed with sealed or closed appliances equipped with
suitable combustion air ducting directly outside. Always maintain adequate distance and protection in order to prevent
the product from coming into contact with water.
In the event there are several appliances installed, the external air inlet must be sized accordingly.
MINIMUM DISTANCES
It is recommended to install the stove detached from any walls and/or furniture, with a minimum clearance to allow eective aeration
of the appliance and a good distribution of heat in the room. Comply with the distances from ammable or heat-sensitive objects (sofas,
furniture, wood panelling, etc.) as specied below. The frontal distance from ammable materials must be at least as specied in the
product’s technical data table.
If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly.
If the oor is made of wood, it is recommended to t a oor protection sheet in compliance with the Standards in
force in the country of installation.

If the oor is made of combustible material, it is recommended to use protection made of non-combustible material (steel, glass...) that
also protects the front from falling combusted material during cleaning operations.
The appliance must be installed on a oor with adequate load capacity.
If the existing construction does not meet this requirement, one must take appropriate measures (for example a load distribution plate).

MAINTENANCE
The ue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising
the ecient functioning of the heater and, if large build-ups accumulate, can catch re. The ue and chimneypot must be cleaned and
checked by a qualied chimney sweep at least once a year. Once the inspection/maintenance has been performed, request a written
report that the system is safe.
Cleaning is critical to the safety of the system
CHIMNEY
The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7.
The area of the opening for smoke extraction must be at least double the cross-section of the smoke duct/ue system, and arranged so
that smoke extraction is ensured even in strong wind. The chimney must prevent rain, snow or animals from entering the chimney. The
height of outow into the atmosphere
must be beyond the reux zone
created by the shape of the roof or any
obstacles near the outlet (see Figures
2-3-4-5-6).

EXTERNAL AIR INLET
It is mandatory to provide an adequate external air intake that supplies the combustion air required for the product to work properly. The
ow of air between the outside and the installation room may be direct, through an inlet in an external wall of the room; or indirect, via
air intake from adjoining rooms and connecting permanently with the installation room (see Figure 9 b). Adjoining areas may not include
sleeping areas, garages or general areas with a re hazard. During installation one must check the minimum clearances required for air
intake from outside. Take into account the presence of doors and windows that could interfere with the proper ow of air to the stove (see
diagram below).
The air inlet must have a minimum net total area of 80 cm2: the surface must be increased accordingly if there are other active generators
(for example: electric fan for stale air extraction, hood, other stoves, etc.), which could cause a depression in the room. Make sure that,
with all appliances on, the pressure drop between the room and the outside does not exceed the value of 4 Pa (also for Oyster appliances
if the combustion air has not been suitably ducted outside). If necessary increase the intake section of the air inlet, which must be made
at oor level and always protected with a bird-proof outer protection grid and in such a way that it cannot be obstructed by any object.
It is possible to connect the air required for
combustion directly to the outside air inlet,
with a pipe of at least Ø50mm, with maximum
length of 3linear metres; each pipe bend shall be
considered equivalent to a linear metre. To attach
the pipe see the back of the stove.
For stoves installed in studio ats, bedrooms and
bathrooms (where allowed), it is mandatory to
connect the combustion air outside. In particular
for sealed stoves the connection must be sealed
in order not to compromise the overall sealed
characteristic of the system.

Use smoke ducts with a diameter of 80mm or 100mm depending on the type of system, with silicone gaskets or similar gaskets that can
withstand the high operating temperatures of the appliance (min. T200 class P1). The use of exible metal tubes in bre cement
or aluminium is prohibited. For direction changes, we always recommend the use of a T joint with an inspection cap allowing
easy access for cleaning the tubes. Always ensure that the inspection cap is replaced and hermetically sealed with the seal in tact after
cleaning.
It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from overhead cowling. It is prohibited to
extract the products of combustion directly through the wall, whether into indoor spaces or outdoors.
The smoke duct must be a minimum distance of 400 mm from ammable or heat-sensitive structures.

15-LOADING THE PELLETS
Technical Dept. - All rights reserved - Reproduction is prohibited
LOADING THE PELLETS
Fuel is loaded through the upper part of the stove by lifting the hatch.
Pour the pellets in slowly so that it is deposited at the bottom of the hopper.
If loading pellets when the stove is running, open the door of the tank using the stove mitten that comes with the
stove itself.
When loading, do not let the pellet bag come into contact with hot surfaces.
Never remove the protection grid inside the hopper.
No other type of fuel other than pellets is to be inserted into the hopper, in compliance with above-mentioned
specications. Store the spare fuel at an adequate safe distance.
Do not pour pellets directly onto the brazier but only into the hopper.
When the appliance is running and when it is turned o, most of the stove surfaces are very hot (door, handle, glass,
smoke outlet pipes, etc.). Therefore it is recommended to avoid coming into contact with these parts.

16-FIRST START-UP
GENERAL PRECAUTIONS
Remove any objects that may burn from the brazier (manual, various adhesive labels or any polystyrene).
Check that the brazier is positioned correctly and rests properly on the base.
LIGHT THE APPLIANCE THE FIRST TIME WITHOUT THE CLADDING, SO THAT THE PRODUCT’S
PAINT CAN DRY, AND TO PREVENT IRREPARABLY DAMAGING THE CLADDING ITSELF.
The rst start-up may not be successful as the feed screw is empty and does not always manage to load the required
amount of pellets in time to light the ame.
ELIMINATE THE ALARM CONDITION OF A FAILED START-UP BY POSITIONING THE OF THE EMERGENCY PANEL TO OFF FOR
ABOUT 20 SECONDS AND BRINGING SELECTOR “D” BACK TO THE REMOTE POSITION. REMOVE THE PELLET LEFT IN THE
BRAZIER AND REPEAT THE START-UP. (SEE “SAFETY DEVICES/ALARMS” PARAGRAPH)
Switch-on/o from the emergency panel
If the remote control is faulty or the batteries are at, the product can be operated in safe mode via the rear emergency panel.
In this conguration, the stove can only operate in manual mode and with the possibility to choose between 3 power levels.
• SWITCHING THE STOVE ON WITHOUT THE REMOTE CONTROL
To switch the stove on move selector “D” to the ON position. The RED LED goes o upon start-up, while the GREEN LED starts to ash until
the start-up stage is complete. Once the product is in steady state, the GREEN LED remains on.
• CHOOSING THE POWER WITHOUT THE REMOTE CONTROL
One can choose between 3 heating powers:
MIN-MED-MAX (selector “E”)
The MINIMUM power corresponds to the 1
st
power;
The MEDIUM power corresponds to the 3
rd
power;
The MAXIMUM power corresponds to the 5
th
power;

16-FIRST START-UP
Technical Dept. - All rights reserved - Reproduction is prohibited
• SWITCHING THE STOVE OFF WITHOUT THE REMOTE CONTROL
To switch the stove o move selector “D” to the “OFF” position.
Once the remote control is restored, remember to set selector “D” back to the “REMOTE” position, otherwise the
product will ignore the remote control commands.
If the ame fails to ignite despite a regular supply of pellets, check the slignment of the brazier, which must rest snugly into its
seating. If no anomaly is found during this inspection, there may be a problem with the product components or installation may not be
correct.
REMOVE THE PELLETS FROM THE BRAZIER AND CONTACT AN AUTHORISED TECHNICIAN.
Please ensure the brazier is clear of ALL pellets and ash build up following any failed ignitions. Failure to clear out
the brazier prior to resetting may result in further failed ignitions or in certain conditions an explosive ignition.
It is good practice to ensure eective ventilation in the room during the initial start-up, as the boiler will emit some
smoke and smell of paint.
Do not stand close to the stove and, as mentioned, air the room. The smoke and smell of paint will disappear after about an hour of
operation, however, they are not harmful in any case.
The boiler will be subject to expansion and contraction during the lighting and cooling down stages, and may therefore make slight
creaking noises.
This is absolutely normal as the structure is made of laminated steel and must not be considered a defect.
DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!! THE PRODUCT NEEDS SOME RUNNING-IN TIME.
It is extremely important to make sure the boiler does not reach high temperatures straight away, but to increase the temperature
gradually using low power at rst.
This will prevent damaging the ceramic or serpentine stone tiles, the welds and the steel structure.
Do not touch the product during the rst lighting, as it is during this phase that the paint sets. If you touch the paint,
you may expose the steel surface.
If necessary, touch up the paint with the spray can of the specic colour.

REMOTE CONTROL OPERATION
General rules
By pressing key A for 1” the product is switched on and o. Key C is used to make all changes. Key E is used to conrm the changes. By
pressing key B one selects the product operating mode. Via key D one browses the FAN and SLEEP setting. Whichever the mode is, press
key A briey (or leave the keypad idle for 7”) to go back to the initial display.
INITIAL SETTINGS
Setting the time
Both with the remote control on and o, by pressing keys B+E at the same time for 3” one accesses the time/day setting mode.
The hour digits will start to ash; they can be changed with key C. By pressing key E the changes are conrmed.At this point the minutes
digits will start to ash.
Follow the same modify/conrm procedure, one will then go onto the time display mode (12h or 24h) and nally
the day will start to ash. Conrm this data to exit the settings.
NOTE: each time the remote control is powered, the time is reset and the display automatically enters the time setting mode.
°C – °F setting
Only with the stove switched o, by pressing key B for 5” one changes the unit of measure of the temperature, from Celsius to Fahrenheit
and vice versa.
SETTING THE OPERATING MODE
With the remote control switched on, key B allows to set one of the 4 product operating modes. Figure 1-2-3-4 displays the 4 basic
displays, respectively: Manual, Automatic, Timer and Eco mode.
MANUAL Mode (MAN)
In this mode one can set the ame power manually (5 levels - act directly on key C to change). Figure 1
AUTOMATIC Mode (AUTO)
In this mode one can set the desired room temperature, and the stove will modulate the ame power automatically to reach the
temperature. Figure 2
If a fan is AUTOMATICALLY set, its speed depends on the power that is running the stove:
In the case of power level 1: V=1
In the case of power level 2: V=2
In the case of power level 3: V=3
In the case of power level 4: V=3
In the case of power level 5: V=3

MANUAL POWER FUNCTION
this function allows you to set the power of the ame from a minimum of 1 to a maximum of 5. The power levels correspond to a dierent
value of fuel consumption, setting 5 heats the room in less time and setting 1 can keep the room temperature stable for a longer period of
time. The set ame is automatically set to a minimum when the set temperature value is reached.
if the bars are all full, the stove is on ame power 5
if only one bar is full, the stove is on ame power 1
If the ventilation is MANUALLY set, the function which limits the maximum power of the stove according to the ventilation is enabled.
COMFORT AIR (2 FANS): maximum power level = total of the levels of ventilation/2.
AIR: maximum power level = twice the total of the levels of ventilation
Even if the power limit is enabled, the display on the remote control does not consider the power limit for ventilation eect.

TIMER Mode (TIMER)
Select this operating mode to switch the product on and o automatically, according to 6 customised time slots (P1 – P6). The following
can be set for each time slot:
• Switch-on time
• Switch-o time
• Desired room temperature in the time slot
• Days of the week in which the time slot is active
When the stove is switched on (manually via key A or automatically via a time slot) the product works in the
automatic mode described above. A time slot appears automatically when it is active (P1 in gure 3) and the desired temperature is
changed according to the value set in the time slot. However, the user can always modify this value as desired and in real time.
Refer to the relevant paragraph to learn how to set the time slots.
ECO Mode (ECO)
This mode is activated/disabled with the remote control switched on by pressing key B for 5”.
ECO is an automatic mode with the only dierence that if the set temperature is reached and remains so for the following 20 minutes
(despite ame modulation), the product switches o and remains on stand-by until the room temperature drops 2 degrees below the
desired temperature (and in any case for at least 5 minutes from the last shutdown). The product is then switched on again. Figure 4
If the room is not suciently insulated, ame modulation does not allow the set temperature to stay satised for 20 consecutive minutes
and the product will not switch o.
NOTE: It is recommended to use the ECO mode only in well-insulated rooms in order to prevent start-up and shutdown
from occurring within short periods of time.
The remote control remains on even when the product is o when in ECO mode, in order to indicate that this shutdown is only
temporary. Obviously, if the product is switched o via key A, ECO mode is exited and the product remains o.
Up to 6 automatic start-up and shutdown time slots (E1 – E6) can also be set in ECO mode, which are independent
from those of TIMER mode (P1 – P6). If they have been activated, TIMER-ECO appears on the display (gure 5) permanently, even if the
remote control is switched o.
Refer to the relevant paragraph to learn how to set the time slots.
NOTE: If the remote control is switched o due to TIMER, ECO cannot be restarted until the user intervenes (key A) or
when the next valid time slot starts. Combined use of TIMER and ECO modes requires a good knowledge of the product
operating logic.

Room ventilation
Room ventilation can be adjusted as desired in all 4 operating modes described above (Manual, Automatic, Timer, Eco). Simply perform
this operation: from the basic display, press key D to access the VENTILATION adjustment mode (Fig. 6). Then press key C (arrows) to
set the desired ventilation by selecting one of the 5 levels available, independent from the ame level.
The “auto” option can also be selected, which automatically links the room ventilation speed to the ame level.
In short:
ame set on 1 > ventilation set on 1; ame set on 3 > ventilation set on 3; ame set on 5 > ventilation remains set on 3 (for silent
operation as it is in automatic mode).
The speed of each fan (identied with 1 or 2 above the level bars) in products with 2 fans (comfort air models) can be scrolled and set via
key D.
NOTE: In the event a replacement remote control is purchased, if you need to change the default setting, proceed as
follows: with the remote control switched on press buttons D + E at the same time for 10 seconds (until the ashing
number appears). Press key C to select 1 or 2 according to the product to which the remote control is to be paired, and
press E to exit.
IMPORTANT! Choosing the right number of fans can become a decisive factor to ensure the stove works correctly. Therefore
ensure an authorised technician conducts the settings.

SAFETY DEVICES
The product is tted with the following safety devices.
SMOKE TEMPERATURE PROBE
It detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset
value.
PELLET HOPPER TEMPERATURE PROBE
If the temperature exceeds the preset safety value, it immediately stops the product, which must cool down before the stove is restarted.
ELECTRICAL SAFETY
The product is protected against power surges by a general fuse located in the control panel on the back. Other fuses that protect the
electronic boards are found on the latter.
SMOKE FAN BREAKAGE
If the fan stops, the circuit board promptly blocks the supply of pellets and the alarm is displayed.
GEAR MOTOR BREAKAGE
If the gear motor stops, the product switches o and the relative alarm is signalled.
TEMPORARY POWER CUT
If a power cut occurs during operation, the product automatically sets itself in cooling mode when the power is restored and then it
restarts.
FAILED START-UP
If no ame lights during start-up, the product will go into alarm conditions.
TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED.
It is possible to relight the product and therefore restore the automatic operation of the probe only after having eliminated the cause of
the intervention of the safety system. This manual will help you understand which anomaly has occurred, and explain how to intervene
according to the alarm message displayed on the appliance.

Feed screw loading function
This function can only be activated when the stove is o and allows the pellets to be loaded into the loading system (feed screw). It can
be used each time the pellets nish in the hopper (see alarm A02). It is useful to prevent failed start-ups (alarm A01) due to the hopper
being empty.
Enable the function as follows:
• Set the rst selector to OFF
• Set the second selector to MED
• Make sure that OFF appears on the display because this function can only be activated with the stove completely cold (o) and the
selector set to OFF.
• Press the TEST key 3 times consecutively within 2 seconds
• “OnPlt” will appear on the display in two subsequent intervals.
• Press the TEST key once again when the pellets begin to fall into the brazier to end the FEED SCREW LOADING function or wait for

21-RECOMMENDATIONS FOR SAFE USE
ONLY CORRECT INSTALLATION AND APPROPRIATE MAINTENANCE AND CLEANING OF THE APPLIANCE CAN GUARANTEE
CORRECT OPERATION AND SAFE USE OF THE PRODUCT.
We would like to inform you that we are aware of cases of malfunctioning of domestic pellet-fuelled heating products, mainly due to
incorrect installation and use, as well as inadequate maintenance.
We would like to assure you that all of our products are extremely safe and certied according to European standards of reference. The
ignition system has been tested with the utmost attention to enhance ignition eciency and to prevent any type of problem, even in the
worst operating conditions. In any case, like for any other pellet-fuelled product, our appliances must be installed correctly and undergo
regular periodical cleaning and maintenance to guarantee safe operation. Our studies show us that malfunctioning is mainly due to the
combination of part or all of the following factors:
• Brazier holes obstructed or brazier deformed, due to lack of maintenance and conditions which can cause delayed ignitions,
generating an anomalous production of unburned gases.
• Insucient combustion air due to a reduced or clogged air inlet duct.
• Use of smoke ducts nonconforming to regulatory installation requirements, failing to guarantee an adequate draught.
• Partially clogged chimney, due to lack of maintenance, reducing the draught and making ignition dicult.
• End chimneypot nonconforming to the indications of the instruction manual, and therefore not suitable to prevent potential inverse
draught.
• This factor is crucial when the product is installed in especially windy areas, such as costal regions.
The combination of one or more of these factors could generate important malfunctioning conditions.
To keep this from occurring, it is fundamental to guarantee that the product is installed in compliance with standards in force.
Furthermore it is of the utmost importance to respect the following simple rules:
• Every time the brazier is removed for cleaning, it must always be put back properly in the work position before using the product,
completely removing any residual lth left on the support base.
• Pellets must never be loaded in the brazier manually, either before ignition or during operation.
• The accumulation of unburned pellets ensuing a failed ignition must be removed before repeating ignition. Also check that they are
fed correctly and that the combustion air inlet/smoke outlet are regular.
• If ignition fails repeatedly, immediately suspend use of the product and contact a qualied technician to check its operation.
Compliance with these indications is absolutely sucient to guarantee proper operation and to avoid any type of problems with the
product.
If the above-mentioned precautions are not taken, and during ignition the brazier is overloaded with pellets thus generating anomalous
smoke in the combustion chamber, carefully follow the indications below:
• Do not disconnect electrical power to the product for any reason whatsoever: this would stop the smoke extractor, releasing smoke
into the environment.
• Take the precaution of opening the windows to ventilate the installation room from any smoke in the environment (the chimney
might not work properly).
• Do not open the re door: this would compromise regular operation of the smoke extraction system to the chimney.
• Just switch the stove o by acting on the on-o button on the control panel (not the rear power supply socket button!) and move
away until smoke has completely evacuated.
• Before attempting re-ignition, clean the brazier and its air passage holes completely of all deposits and unburned pellets. Put the
brazier back in place, removing any residue from its support base. If ignition fails repeatedly, immediately suspend use of the product
and contact a qualied technician to check its operation and the chimney.

22-CLEANING
Technical Dept. - All rights reserved - Reproduction is prohibited
Only by properly servicing and cleaning the product is it possible to ensure its safety and correct operation.
CAUTION!
All the cleaning operations of all parts must be performed with the product completely cold and the plug
disconnected.
Disconnect the product from the 230V power supply before performing any maintenance operation.
The product requires little maintenance if used with certied good quality pellets.
DAILY OR WEEKLY CLEANING PERFORMED BY THE USER
Brazier cleaning
Before ignition, always clean the “T” brazier and remove any ash or incrustation from it that might obstruct the air ow holes, paying
attention to hot ash. In the case of ignition failure, or if fuel in the tank runs out, unburned pellets may accumulate in the brazier. Always
empty the residue in the brazier before each start-up. You may only use a vacuum cleaner to remove ash when it is completely
cold. In this case, use a suitable vacuum cleaner to remove small sized particles.
EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER
64
21-RECOMMENDATIONS FOR SAFE USE
REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE SAFE IGNITION AND OPTIMAL
OPERATION OF YOUR PELLET PRODUCT. IN CASE OF FAILED IGNITION AND AFTER ANY OTHER LOCK STATE OF THE
PRODUCT, IT IS ESSENTIAL TO EMPTY THE BRAZIER BEFORE EVERY RESTART.
For the brazier to be cleaned properly, remove it from its housing completely and thoroughly clean all the holes and the grate on the
bottom. If good quality pellets are used, you will normally only need to use a brush to restore the optimal operating conditions of the
component.
Ash pan cleaning
Remove and empty the “U” ash tray. Wipe away any residual ash before reinserting the pan. Your experience and the quality of the pellets
will determine the ash tray cleaning frequency. However, it is recommended not to exceed 2 or 3 days.
CLEANING THE GLASS
It is recommended to clean the ceramic glass with a dry brush, or if it is very dirty, spray a little specic detergent and clean with a cloth.
ATTENTION!
Do not use abrasive products and do not spray the glass cleaning product on the painted parts and on the door
gaskets (ceramic bre cord).
CLEANING THE AIR FILTER
A wire mesh air lter is found at the back of the stove, whose purpose is to prevent dirt entering the motor body and the internal sensor.
It is recommended to check that the lter is clean every 15/20 days. If needed remove u or the material that has deposited on it.
Inspection and cleaning are required more frequently if there are pets in the house.
Simply remove the lter to clean. To clean it use a brush or a damp cloth or compressed air. Set it back in place by simply pressing it
(interlocks).
The lter is made of metallic mesh and is soft and exible to the touch therefore, when cleaning, be careful not to
crush or damage it. In the event of breakage it must be replaced.
ATTENTION!
Never let the stove work without the air lter tted. MCZ cannot be held liable for any damage caused to the internal
components if this requirement is not complied with.

PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN
CLEANING THE HEAT EXCHANGER AND THE LOWER COMPARTMENT
Half-way through the winter season, but especially at the end, the compartment through which the exhaust smoke passes will need
to be cleaned.
This cleaning process is mandatory in order to facilitate the general removal of all combustion residue, before it becomes very dicult to
remove it due to the humidity compacting it over time.
CAUTION:
cleaning is mandatory to be performed at the end of the season by an authorised and skilled technician so that even
the seals can be replaced.
CLEANING THE EXCHANGER
Open the stove door, remove the brazier and the ash pan. Then remove the inside of the rebox starting from the two side pieces “M”
and “N”. Extract these parts by lifting them slightly upward and pulling them towards you. Then remove the back “L” following the same
procedure. Attention! Once the back “L” is removed, part P which is at the top and rests on part L tends to drop. Also remove this part and
clean any accumulated dirt. Remove the plate “O” by making it come out of the couplings and clean the walls of the rebox with a rigid rod
or a bottle brush so that the dirt falls into the lower compartment.
Once you have nished cleaning (including the upper exchanger, see following page) restore all disassembled parts.

CLEANING THE LOWER COMPARTMENT
At this point you can remove the four screws “k”, the plate “G” and the gasket “H” and then clean the lower compartment where all the dirt
deposits of the previous cleaning have accumulated. Even in this case, if necessary, replace the gasket “H”.
CLEANING THE SMOKE EXHAUST SYSTEM AND GENERAL CHECKS
Clean the smoke extractor system, especially around the “T” joints, elbows and any horizontal sections of the smoke duct.
For information on periodically cleaning the ue, contact a skilled chimney sweep.
Check the seal of the ceramic bre gaskets on the door of the stove. If necessary, order new replacement seals from the retailer or contact
an authorized service centre to carry out this task.
CAUTION:
The frequency with which the smoke outlet system is cleaned depends on the use of the boiler and the type of
installation.
We recommend relying on an authorised service centre for end-of-season cleaning and maintenance, as they will
carry out all of the previously mentioned work and inspect the stove components.

68
21-RECOMMENDATIONS FOR SAFE USE
PERIODICAL CHECK OF THE DOOR CLOSURE
Make sure the door closure ensures a correct sealing action (with the “paper sheet” test) and that when the door is closed, the closing block
(X in the gure) does not protrude from the sheet metal to which it is secured. For some products it will be necessary to disassemble the
cladding to be able to assess the anomalous protrusion of the block when the door is closed.
69
21-RECOMMENDATIONS FOR SAFE USE
Technical Dept. - All rights reserved - Reproduction is prohibited
END-OF-SEASON SHUTDOWN
At the end of each season, before switching the product o, it is recommended to remove all the pellets from the hopper with a vacuum
cleaner with a long pipe.
When not in use the appliance must be disconnected from the mains power supply. It is recommended to remove the
power cable for additional safety, especially in the presence of children.
The service fuse may have to be replaced if the control panel display does not switch on when the product is switched on again by pressing
the main switch on its side.
There is a fusebox on the side of the product, near the power socket. Open the fusebox cover with a screwdriver and replace the fuses if
necessary (3.15 A delayed) - seek assistance from an authorised and qualied technician.
CHECKING THE INTERNAL COMPONENTS
ATTENTION!
The internal electromechanical components must only be checked by qualied personnel whose technical expertise
includes combustion and electricity.
We recommend that an annual maintenance service is carried out with a scheduled service contract. This service is essentially a visual and

  • het signaal van de afstandsbediening wordt die opgepikt door de kachel zelf. Iemand een idee hoe op te lossen (de batterijen zijn nog goed). Gesteld op 6-4-2019 om 11:58

    • Ik begrijp uw vraag niet!
      Kunt u deze anders stellen aub, want het is toch logisch dat het signaal door de kachel ontvangen wordt!
      Wellicht bedoelt u dat de kachel het signaal niet goed ontvangt?

  • Zet aan de zijkant de kachel op off en medium.
    Controleer of off verschijnt
    Druk binnen 2 seconden 3x op testknop
    Display geeft aan: toevoer-schroef
    Als je de pellets hoort vallen druk dan op test
    en wacht tot deze toevoer - schroef verdwijnt ( kan 6 minuten duren)
    Schakel.de kachel weer in!

    • De kachel gaat in de eco modus pas uit als de gevraagde temperatuur gedurende 20 minuten na het bereiken van de gevraagde temperatuur nog niet is gedaald.

  • Mijn mcz stream gaat uit en dan na 20 minuten geeft hij weer pellets maar komt er geen vlam.
    Daarna kachel uitgezet en opnieuw opgestart.
    Heeft iemand de verklaring hiervoor?
