Extraction of combustion air from outside
In this case, a possible alternative may be:
• to channel the combustion air using a coaxial
exhaust pipe to expel the flue gases and extract
the air (Fig. 7 - A, B = Air inlet, C, D = Flue gas
outlet); in this case it is not necessary to create
a classic air intake in the room;
• to connect the combustion air inlet of the ap-
pliance to the air intake using a special pipe
(Fig. 8).

Extraction of combustion air in the room
Create the air inlet on the wall (Fig. 9 - PA = Air
Inlet), and allow the appliance to take air into the
room.
If the rear wall of the appliance is an external wall,
make a hole for the intake of combustion air at a
height of about 20-30 cm from the ground, re-
specting the dimension indications given on the
technical data sheet at the end of the booklet.
A non-closable permanent aeration grid must
be placed externally; in areas that are particularly
windy and exposed to weathering, provide rain
and wind protection.
Ensure that the air intake is positioned so that it
won't be accidentally obstructed.
If it is impossible to create an external air intake
in the wall behind the appliance (non-perimeter
wall), a hole must be made in an external wall of
the room where the appliance is positioned.
If it is not possible to create the fresh air intake in
the room, an external hole can be created in an
adjacent room provided it is permanently inter-
connected by means of a transfer grille.
It is forbidden to take combustion air from ga-
rages, warehouses of combustible material or
places with activities at risk of fire.
If there are other heating appliances in the room,
the combustion air inlets must guarantee the
necessary volume of air for the correct operation
of all devices.
