Safe operaration is possible provided that
the underpressure in the room where the
burner is installed does not exceed 4 Pa
(0,04 mbar).
This can be achieved if combustion air can
flow through non- lockable openings, e.g.
in doors, windows and via the air-
intake/exhaust air wall box, or by the other
technical measures, such as reciprocal
interlocking. Etc…
If the air intake is inadequate there is a
risk of poisoning from combustion
gases which are drawn back into the
room.
An air-intake/exhaust air wall box by itself
is no guarantee that the limiting value will
not be exceeded.
Note: when assessing the overall
requirement, the combined ventilation
system for the entire household must be
taken into considertion. This rule does not
apply to the use of cooking appliances,
such as hobs and ovens.
If the exhaust air is going to be
discharged into the open, a telescopic
wall box should be fitted into the
outside wall.
