the standards in force. The air must be taken directly from
the outside, from an area far from sources of pollution.
The ventilation aperture must have the following
characteristics (fig.3A):
· total free cross section of passage of at least 6 cm² for
every kW of rated heating capacity of the appliance,
with a minimum of 100 cm² (the heating capacity is
indicated on the rating plate);
· it must be made in such a way that the aperture, both
on the inside and outside of the wall, cannot be
obstructed;
· it must be protected, e.g. with grills, wire mesh, etc. in
such a way that the above-mentioned free section is
not reduced;
· it must be situated as near to floor level as possible.

The air inflow may also be obtained from an adjoining
room, provided the latter is not a bedroom or a room where
there is a risk of fire, such as garages, mews, fuel stores,
etc. and is ventilated in compliance with the standards in
force. Air from the adjoining room to the one to be ventilated
may be made to freely pass through permanent apertures
with a cross section at least equal to that indicated above.
These apertures may also be obtained by increasing the
gap between the door and the floor (fig.3B).
