INSTRUCTIONS OF USE 17
3.
•
The first time the appliance is lit,
the fire should be gentle to allow the
parts of the appliance to dilate and dry.
Important: The first time it is lit up, the
appliance may give off smoke and strange
smells. This is not a cause for concern.
Open an outdoor window to ventilate the
room during the first few hours of
operation.
If you notice water around the
appliance, this is produced by the
condensation of the moisture in the wood
on lighting the fire. This condensation will
no longer appear when the appliance has
been lit three or four times and has
adapted to its flue. If it does not disappear,
then check the flue draught (length and
diameter of the flue, flue insulation,
airtightness) and the humidity of the wood
used.
3.4. Loading fuel
In order to load firewood, open the
firebox door gently, preventing the sudden
entry of air to the firebox so that smoke
does not enter the room that the appliance
is installed in.
Perform this operation with the glove to
prevent burns to the hands.
The maximum load height is 2 logs with
diameters of approx. 10 cm.
The minimum interval between loads
for nominal heat output is 60 minutes.
Always load with the nominal amount
(see table in section 1.1).
For minimum burning (e.g. at night), use
thicker logs.
When the firebox is loaded, close the
door.
Be careful when placing logs in the firebox
on appliances with vermiculite interiors.
Vermiculite is a fragile material and may
crack if knocked.
3.5. Operation
The appliance should be operated with
the door closed.
For safety reasons, never close all the
appliance’s combustion -air intakes.
Primary-air intake
By opening this inlet, air enters the
firebox via the firebox grille.
Secondary-air intake
By opening this inlet, air enters the
firebox via the top of the firebox door.
IMPORTANT : Keeping the secondary-air
intake open helps keep the door glass
cleaner for longer.
Double-combustion air intake
By opening this inlet, air enters the
combustion flame, making for more
efficient and less polluting combustion
because post-combustion takes place,
burning the particles which were not
burned in the first combustion. This
increases the performance of the appliance
and reduces emissions.
On Itaca models, the double-
combustion air intake is the same as the
secondary-air intake (both air intakes are
controlled through the same inlet at the
same time).
IMPORTANT: The appliance is exposed to
extreme changes in temperature and may,
as a result, make noises when in operation.
These noises are a natural result of
expansion/contraction of the parts which
