The stove is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
1A - PRIMARY air register (Picture 6 at page 41)
With the primary air control (movable valve), which is found below the hearth door 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 re 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(see chapter NORMAL OPERATION).
2A - SECONDARY air register (Picture 6 at page 41)
On the inferior part and on the over part of the door there is the secondary air control. Also this register must be opened (then moved
to the right), especially for wood 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 ue of the chimney, it is
possible to keep the glass clean.
The adjustment of the registers necessary to reach the rated caloric yield is the following one:

6. 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 38 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.
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).
6.1. 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 38) .
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 39).
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.
