CHAUFFAGE FRANCAIS Sannover Bedienungsanleitung Seite 22

Below the hearth door will be found an extractable ash-drawer with a closing door (Picture 9).
The heating of the environment is made by:
• Convection: (70%) the air passage through the double mantel of the stove releases heat into the environment;
• Irradiation (30%): through the panoramic glass and the external hot surfaces of the stove, the heat is radiated into the environment.
( see chapter CALCULATION OF THE THERMAL POWER).
The stove is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
A - PRIMARY air register (Picture 9)
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 for the combustion.
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. The register is open when the lever is completely pulled out. The
register is closed when the lever is introduced (see chapter NORMAL OPERATION).
B - SECONDARY air register (Picture 9)
Over the hearth door there is the secondary air register. Also this control must be opened, especially for wood combustion, so that
unburnt carbon does not undergo a post-combustion (see chapter NORMAL OPERATION).
C- TERTIARY air register (Picture 9)
Behind the stove there is the tertiary air. It is adjustable. Tertiary air is should be open all time. Flue gas emissions are reduced by
tertiary air.

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 flues 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.
The minimum section must be 4 dm2 (for example 20x20 cm) for appliances whose pipe dimensions are less than 200 mm, or 6.25
dm2 (for example 25x25 cm) for appliances with a diameter of more than 200 mm
The draught created by your flue must be sufcient but not excessive
A section of the flue which is too large can present a volume which is too large to heat and therefore cause operating difculties 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 flue connection and flammable materials please follow the requirements provided.
The flue must be at a suitably distance from flammable or combustible material using suitable insulation or an air space.
It is FORBIDDEN to pass system piping or air ducts inside the flue. It is also forbidden to create moveable or fxed openings on the flue
itself, for the connection of further different appliance.
