Operating modes

Exhaust air mode. See M Figures.
The extractor-hood fan extracts the
kitchen vapours and conveys them
through the grease filters into the
atmosphere.
The grease filter absorbs the solid
particles in the kitchen vapours.
The kitchen ist kept almost free of
grease and odours.
The exhaust air is discharged upwards
through a ventilation shaft or directly
through the outside wall into the open.
Exhaust air should neither be directed
into a smoke or exhaust flue that is
currently used for other purposes, nor into
a shaft that is used for ventilation rooms in
which stoves or fireplaces are also
located.
Exhaust air may be discharged in
accordance with official and statutory
regulations only (e.g. national builing
regulations).
Local authority regulations must be
observed when discharging air into smoke
or exhaust air flues that are not otherwise
in use.
When the extractor hood is operated
in exhaust-air mode simultaneously
with a different burner (such as gas, oil
or coal-fired heaters, continuous-flow
heaters, hot-water boilers) care must be
taken to ensure that there is an
adequate supply of fresh air which will
be needed by the burner for combustion.
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.
