Extraction of combustion air in the room
Create the air intake on the wall ( Fig. 23 and Fig. 24 -
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,
make a hole for the intake of combustion air at a
height of about 20-30 cm from the ground, observing
the dimensions on the technical data sheet in section
"4.3 Technical features" on page 67 .
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 interconnected by
means of a transfer grille.
It is forbidden to take combustion air from garages,
warehouses of combustible material or places with
activities at risk of fire.
If there are other heating or extraction
appliances in the installation room,
combustion malfunctions may occur
due to a lack of combustion air.
The combustion air intakes must there-
fore be sized correctly, in order to ensure
the necessary supply of air for the cor-
rect operation of all devices.
