aCCESSOrIES
The heating of the environment is made by irradiation: through the panoramic glass and the external hot surfaces of the stove, the heat is
radiated into the environment. The device is equipped with registers of primary and secondary air by which it is adjusted the combustion air.
a - SECONDary air register
Over the door of the hearth there is the secondary air control.
This regulator must be open (the lever must be moved to the right), especially for wood combustion, so that unburnt carbon undergoes
a post-combustion (see chapter NORMAL OPERATION).
Through this register it is possible to adjust the power of the stove. Leaving it slightly open, according to the flue of the chimney, it is
possible to keep the glass clean.
B - PrIMary air register Picture 6
With the thermostat placed on the back of the right side of the stove, it is adjusted the passage of air through the ash drawer and the grate
in the fuel direction. The primary air is necessary for the combustion process. The ash drawer must be regularly emptied, so that the ash
does not obstruct the primary air entry. Through the primary air the fire is also kept alive.
During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns fast and the
stove may overheat. For the correct arrangement (see paragraph NORMAL OPERATION).
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

Lighting Operation :
Open the secondary air register (a), primary air register (B), open the ignition control (C), light up the fire.
The openings for air (primary and secondary) must be opened together just a little (you must open the eventual butterfly valve placed on
the pipe of smokes exhaust). See chapter LIGHTING.
After about 10 minutes, when the fire is lighted, close the thermostat (B) and the ignition control (C) and adjust the combustion course
with the controls (a).
Load The fuel:
Before opening the hearth door, open the ignition control (C), load the fuel, close the door and after about 5 or 10 minutes close the
control (C). IMPOrTaNT: we suggest you to open the door very slowly, to avoid the exit of smokes.
WarNING: When fuel is added onto the embers in the absence of a flame, a considerable amount of fumes may develop. Should
this happen, an explosive mixture of gas and air may form, and in extreme cases an explosion may occur. For safety reasons it is
advisable to perform a new lighting procedure with the use of small strips.
