INDIRECT AERATION
If the heater room cannot be aerated directly,
indirect ventilation can be used, taking the
air from a nearby room via an opening at the
foot of the door (fi gure 12-13).
This solution is possible however only if:
a) the nearby room has adequate direct ven-
tilation as foreseen for direct aeration;
b) the nearby room is not used as a bedro-
om;
c) the nearby room is not a common part of
the building and is not a room where there
is a fi re risk (such as a fuel store, a garage,
etc).
d) the nearby room has a correct direct aera-
tion and free air passage from one room
to the other is ensured

The ventilation of the near by premises is no
longer suffi cient to guarantee suitable venti-
lation to the premises in which the appliance
is installed, for example, for the installation
of a fl ue (see same point in direct ventilation.
