It is possible to get the combustion air directly from outside through a flexible tube fireproof NOT furnished (see chapter VENTILATION
HOOD OR ADJACENT LOCAL).

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;
• all the sections of the flue gas duct must be accessible to inspection;
• inspection openings must be provided for cleaning.
• 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. Picture 1
For a correct installation please respect the sections/lengths of the flue shown in the technical data table. By installations
with different dimensions the flue must be suitably sized in accordance with EN13384-1.
The draught created by your flue must be sufficient 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 difficulties 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 by UNI 10683 standard. 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 fixed openings on
the flue itself, for the connection of further different appliances (see chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE
FLUE).

CHIMNEY POT

The flue 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 flue
As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind
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 flue.
• Be built so as to prevent rain, snow or any foreign body entering the flue.
• Be easy to inspect, for any maintenance and cleaning operations.

CONNECTION TO THE CHIMNEY

Products with automatic door closing (type 1) must operate, for safety reasons, with the furnace door closed (except during the fuel loading
or ash removal phases).
Products with non-automatic door closing (type 2) must be connected to their own flue.
Operation with doors open is only allowed when supervised.
The connection pipe to the flue must be as short as possible, straight horizontal and positioned slightly in ascent, and watertight.
Connection must be carried out with stable and robust pipes,comply with all current standards and Regulations and to those envisioned by
the law, and be hermetically secured to the flue. The internal diameter of the connection pipe must correspond to the external diameter of
the appliance flue gas exhaust stub pipe (DIN 1298).
ATTENTION: as far as concern the realisation of the flue connection and flammable materials please follow the requirements
provided by UNI 10683 standard. The flue must be properly spaced from any flammable materials or fuels through a proper
insulation or an air cavity. Minimum distance safety 25 cm.
