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 cooker is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
1A – PRIMARY AIR CONTROL (Picture 6 at page 62)
With the inferior air control, which is on the re door, it is adjusted the passage of primary air into the low part of the cooker, through
the drawer of ash 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 for the combustion. Through the primary air the re is also kept
alive. In order to open the air ow, the bar must be completely pulled out (when the bar is completely pushed to the back, the control is
closed). During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns too fast
and the cooker may overheat.
2A – SECONDARY AIR CONTROL (Picture 6 at page 62)
On the hearth door there is the secondary air register. This register must be totally moved to the right in order to open the control,
especially for wood combustion (see paragraph Table). The secondary air, passing between the double glass of the re door, heats itself
starting the double combustion and keeping at the same time the glass clean (with open register).
The control regulation necessary in order to obtain nominal caloric output is the following (see Cap. TECHNICAL DATA):

7. FLUE
Essential requirements for correct appliance operation:
the internal section must preferably be circular;
the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to heat, combustion
products and any condensation;
there must be no narrowing and vertical passages with deviations must not be greater than 45°;
if already used, it must be clean;
the technical data from the instruction manual must be respected;
If the ues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm.
For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.
A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.
The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel, rough
and porous internal surfaces. Picture 1 at page 59 shows some example solutions.
The minimum section must be 4 dm
2
(for example 20x20 cm) for appliances whose pipe dimensions are less than 200 mm, or 6.25
dm
2
(for example 25x25 cm) for appliances with a diameter of more than 200 mm.
The draught created by your ue must be sufcient but not excessive.
A section of the ue which is too large can present a volume which is too large to heat and therefore cause operating difculties for the
appliance; to avoid this, it is necessary to intubate the appliance for its entire height. A section which is too small causes a reduction in
draught.
ATTENTION: as far as concern the realisation of the ue connection and ammable materials please follow the requirements provided by
UNI 10683 standard. The ue must be at a suitably distance from ammable or combustible material using suitable insulation or
an air space.
It is FORBIDDEN to pass system piping or air ducts inside the ue. It is also forbidden to create moveable or xed openings on the ue
itself, for the connection of further different appliances (See chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE).
7.1. CHIMNEY POT
The ue draught depends on the suitability of the chimney pot.
It is therefore essential that, if built in a handcrafted way, the exit section is more than twice the internal section of the ue
(Picture 2 at page 59) .
As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind (Picture 3 at page 60).
The chimney pot must meet the following requirements:
Have an internal section equivalent to that of the chimney.
Have a useful exit section of double the internal section of the ue.
Be built so as to prevent rain, snow or any foreign body entering the ue.
Be easy to inspect, for any maintenance and cleaning operations.
