13. OPERATION DURING TRANSITION PERIODS

During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it
can happen that the combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently
and increase the air for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning
(growing up of the flames) and the stabilization of the draught.
Then, check that all openings for the cleaning and the connections to the stack are air-tight.

14. MAINTENANCE AND CARE

14.1.

CLEANING OF THE FLUE

During normal use, the fireplace is not damaged in any way.
The appliance should be completely cleaned at least once a year or every time it is needed (in case of bad working
and low yield). An excessive deposit of soot can cause problems in the discharge of the smokes, as well as fire in the
flue. The cleaning must be carried out exclusively with cold equipment.
This operation should be carried out by a chimney sweeper who can simultaneously perform an audit of the flue
(checking of possible deposits). During the cleaning, it is necessary to remove from the appliance the ash drawer
(Picture 20 A), the grating (Picture 20 B) and the smokes deflector (Picture 20 C) to ease the fall of the soot.
To extract the deflector, it is sufficient to lift it from the rear and extract it from the front.
Once the cleaning has been completed, the same has to be positioned back in its seat.
CAUTION: The lack of the deflector causes a strong depression, with a too fast combustion, an excessive
consumption of wood with related overheating of the appliance.
14.2.

CLEANING OF THE GLASS

Thanks to a specific entry of the secondary air the building of deposit on the glass of the door is slowed down in a
remarkable way. However the building of this deposit cannot be avoided with the use of solid fuels such as humid
wood, and this is not to be considered as a defect of the appliance.
IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold appliance to
avoid the explosion of the same. For the cleaning, it is possible to use specific products or a
wet newspaper paper ball passed in the ash to rub the glass itself.
The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air
regulator, enough draught of the chimney-flue and the presence of combustion air are the essential elements for the
optimal functioning of the appliance and for the cleaning of the glass.
BREAK OF GLASSES:
Considering that the glasses are manufactured in glass-ceramic and resistant to heat shock up to 750 °C,
they are not subject to thermal shocks. Their break can be caused only by mechanic shocks (bumps or
violent closure of the door, etc.). Therefore, their replacement is not included in the warranty.
14.3.

CLEANING OF THE ASH

All the appliances are equipped with a hearth grating and
an ash drawer for the collection of the ashes (Picture 20
A).
It is suggested to empty periodically the ash drawer and
to avoid it fills completely in order not to overheat the
grating. Moreover, it is suggested to leave always 3-4 cm
of ash in the hearth.
The ashes removed from the hearth have to be stored in
a container made of fire-resistant material equipped with
an air-tight cover.
The container has to be placed on a fire-resistant floor,
far from flammable materials up to the switching off and
complete cooling.
Check the external air intake, by cleaning it, at least once
a year.
The stack must be regularly swept by the chimney
sweeper.
Let your chimney sweeper in charge of your area check
the regular installation of the appliance, the connection to the stack and the aeration.
