If it is white, it means that the appliance is not properly adjusted or the wood is too wet; if instead the smoke is gray or
black, it signals that the combustion is not complete (it is necessary a greater quantity of secondary air).

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 stack is not damaged in any way.
The appliance should be completely cleaned at least once a year or every time it is needed. 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. During the
cleaning, it is necessary to remove from the appliance the ash drawer, the grating and the smokes deflector 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 inlet of secondary air, the accumulation of dirty sediments on the glass-door is reduced with
efficacy. Nevertheless this can never be avoided by using solid fuels ( particularly wet wood ) and it has not to be
understood as a defect of the appliance.
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.
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.
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.
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.

15. SUMMER TIME

After having performed the cleaning of the hearth, of the stack and of the flue, by removing completely the ash and
other possible residuals, close all hearth doors and related registers.
It is suggested to perform the flue cleaning at least once a year; in the meantime, verify the actual state of the door
seals, which do not assure the good operation of the appliance, if they are not completely integral (i.e. if they do not
adhere anymore to the door)! Therefore, it is necessary to replace them.
