Extraction of combustion air in the room
Create the air intake on the wall (Fig. 18 and Fig.
19 - 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 res-
onance effects.

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,
respecting the dimension indications given on
the technical data sheet "4.3 Technical features"
on page 62.
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-
PA
rages, warehouses of combustible material or
places with activities at risk of fire.
