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 make an external air intake
in the room, it is possible to make the external
hole in an adjacent room as long as it perma-
nently connects via passage grille (Fig. 19 - C =
Container, G = Grille, S = Damper).

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.
If one or more extraction fans (extrac-
tor hoods) are present and operating
in the installation room, combustion
malfunctions may occur due to lack of
combustion air.
