6.4 Combustion air

The appliance, during its operation, requires
combustion air.
The inflow of combustion air can be obtained in
the following ways:
• it can come directly from outside with direct
connection to the combustion chamber (Fig.
16).
• it can come from the installation room or suita-
ble adjacent rooms (Fig. 16)
Extraction of combustion air from outside
In this case it is possible to connect the combus-
tion air inlet of the appliance to the air inlet with
a suitable duct (Fig. 15).
Extraction of combustion air in the room
Create the air intake on the wall (Fig. 16 - PA =Air
Intake), and leave the appliance to withdraw the
room air, making sure to connect the section of
corrugated pipe on the air inlet pipe, if supplied,
fixing it with the strap and folding it slightly
downwards to prevent any resonance effects.

If the rear wall of the appliance is an external
wall, create a hole for the intake of combustion
air at a height off the ground of about 20-30 cm,
in accordance with the dimensional instructions
reported in the section "4.3 Technical features"
on page 55.
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
Fig. 15
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.
