Functioning in mid-seasons
To suck the air for fuelling and to dischar-
ge smoke, the CRISTAL hearth requires
draught from the chimney/flue. With the
increase of the external temperatures, the
draught decreases. Verify the chimney
draught before lighting the fire, in case
external temperatures are higher than
10°C.
If the draught is weak, initially ignite a
“starting” fire using small sized igniting
material. Once the correct chimney
draught is restored, you can introduce the
fuel.
Air flow in the room where the hearth is
installed
The TITANO PLUS hearth is able to work
regularly only if in the room where it is
installed there is sufficient air flow for the
fuelling. Provide a sufficient air flow befo-
re igniting the chimney.
The air power supply devices for fuelling
must not be altered.
Whenever the air volume results scarce
and the type of building in which the chim-
ney is installed particularly air sealed, it
will be necessary to install a supplementa-
ry air inlet of 150 cm² as previously said.
Igniting with cold hearth
1. Check that the ash bed is not too high.
Maximum height: 5 cm underneath the
hatch edge. If the ash bed becomes too
high, there is a danger that when opening
the hatch to add wood, fragments of coal
may fall out of the hearth.
2.Pull the regulating lever of the air valve
in the “switch on” position. Air for fuelling
will flow intensely to the wood in the
hearth, to rapidly reach good fuelling.
3. The wood must be placed in the hearth
without excessively crowding it. Place an
igniter between the wood logs, and ignite.
The igniters are practical aids to start the
fuelling.
Attention: very large wood logs do not
ignite properly in a cold hearth and free
noxious gasses. Never use material such
as petrol, alcohol and similar to ignite
the hearth!
4.At this point, close the hearths hatch and
supervise for a few minutes. Should the
fire go out, slowly open the hatch, allocate
another igniter between the wood logs and
re-ignite.
5. Should the fire not require further addi-
tion of wood, the moment the same fire is
exhausted, push the regulating lever of the
air valve in the “maintain fire” position.
Do not carry out such regulation during the
fuelling phase, in that, when the lever is in
the maintain fire position, the air flow for
fuelling results completely blocked.
Fuel and heating power
The fuelling has been optimised from a
technical point of view, both with regard to
the conception of the hearth and the respecti-
ve air power supply, and with regard to the
emissions.
We invite you to support our commitment in
favour of a clean environment by observing
the following indications with regard to the
use of fuelling materials which do not con-
tain, nor produce, noxious substances.
Only use natural and seasoned wood, or
wood briquettes, as fuel. Damp wood, freshly
cut or stored incorrectly has a high water con-
tent and therefore does not burn well, produ-
ces smoke but very little heat.
Only use burning wood with minimum two
years seasoning in an airy and dry room. In
such case, the water content will result lower
than 20% of the weight. In this way you will
save in fuelling material, as the seasoned
wood has a higher heating power.
Never use liquid fuel such as petrol, alcohol
or similar. Do not burn waste.
Radiation field
Do not place any fuel object inside the radia-
tion field of the glass hatch.
Initial start-up
The paint of the hearth is subject to the so cal-
led ageing until the working temperature is
reached for the first time.
This may cause unpleasant odours. In such
case, adequately air the room where the
hearth is installed. The phenomenon will
disappear after the first ignitions.
Danger of burns
The external surfaces of the TITANO PLUS
hearth, in particular the glassceramic panel,
heat up. Do not touch - danger of burns!
Children should be particularly warned.
However, children must be kept away from
the switched on hearth.
Air grills
Careful not to close or obstruct the hot air
outlets. This causes danger of overheating
inside the covering.
Hearth functioning with hatch open
In case of functioning with hatch open, the
hearth will have to be constantly kept under
control. Very hot coal may be projected outsi-
de the hearth.
Addition of fuel
The use of a protective glove is suggested to
“add wood”, in that, in case of prolonged use,
the handle may heat up.
Slowly open the hatch. In this way, the for-
ming of a vortex of leaking smoke is avoided.
When is it time to add wood? When the fuel
has almost turned to coal.
In case of sudden oxygen flow (for ex. due
to the opening of the hearths panel) the
“gasses still present” in the hearth and in
the eventual heat recovery surfaces, may
react violently with said atmospheric inco-
ming oxygen.
Power supply with hot hearth
With the glove provided, slowly lift the
hatchand add the desired amount of wood
in the hearth, placing it on the existing
coal. In this way, the wood will heat up
with the consequent expulsion, in the form
of steam, of the contained humidity. This
leads to a decrease of the temperature insi-
de the hearth. The volatile substances let
out at this point by the fuelling material,
require a sufficient air flow, so that this cri-
tical phase, from a technical point of view
of the emissions, can be rapidly carried out
and the required temperature can be rea-
ched for correct fuelling.
A further suggestion:
For the initial ignition of the hearth,
always use the smaller wood logs. These
rapidly burn and therefore bring the hearth
to the right temperature in less time. Use
the larger wood logs to re-power the
hearth.
Certain types of wood briquettes inflate
once they are in the hearth, meaning they
stretch under the heat and increase in volu-
me.
Always place the wood well inside the
hearth, nearly touching the rear wall of the
same, so that should it slide, it does not fall
in the hatch.
Removing the ash
You can remove the ash using a shovel or
with an ash sucker. Only place the ash in
non fuelling containers, bearing in mind
that the residual coal may re-ignite even
after more than 24 hours from last fuelling.
N.B. The seasoned wood has a heating
power of about 4 kWh/kg, whereas fresh
wood has a heating power of only 2
kWh/kg. Therefore, to obtain the same
heating power, double the fuel is required.

ATTENTION: If the hearth is powered

inadequate fuel, the risk of over-heating
may be incurred.
