the stove is positioned.
If it is not possible to create the external air intake
in the room, an external hole can be created in
an adjacent room provided it communicates
permanently with a transit grille. (Fig. 5.4b - C =
Container, G = Grille, S = Damper)
The UNI 10683 standard prohibits the taking of
combustion air from garages, combustible material
warehouses or activities with the risk of fire.
If there are other heating appliances in the room,
the combustion air intakes must guarantee the
necessary volume of air for correct operation of all
the devices.
In the event that one or more extraction fans (suction
hoods) are present and functioning in the room
where the stove is located, combustion malfunctions
due to the lack of combustion air could occur.
12.5 Fume evacuation
The stove operates with the negative pressure in the
combustion chamber and so, it is essential to ensure
that the fume outlet is leak-proof.
The stove must be connected to its own exclusive fume
discharge system which can adequately disperse the
combustion products into the atmosphere.
The components that make up the smoke evacuation
system must be declared suitable for the specific
operating conditions and provided with CE marking.
It is mandatory to create a first vertical
section measuring at least 1.5 meters to
guarantee correct expulsion of the fumes.
It is advisable to make a maximum of 3 changes of
direction, in addition to that resulting from the rear
connection of the stove to the fireplace, using 45-90°
bends or T-fittings (Fig. 5.5a).
Always use a T-fitting with an inspection cap at
each horizontal and vertical variation of the flue gas
exhaust path.
On the first T, at the outlet of the stove's
fume exhaust, it is necessary to connect
a pipe at the bottom for the evacuation
of any condensation that may form in
the flue (Fig. 5.5b).
The horizontal sections must have a maximum length
of 2-3 m with an upward slope of 3-5% (Fig. 5.5a).
