Prior to installation
The exhaust air is discharged upwards
through a ventilation shaft or directly
through the outside wall into the open.
D
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 ventilating 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 building
regulations).
Local authority regulations must be
observed when discharging air into smoke
or exhaust flues that are not otherwise in
use.
D
When the extractor hood is operated
in exhaust-air mode simultaneously with
a different burner which also makes use
of the same chimney
(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 operation 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
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 consideration. This rule does not
apply to the use of cooking appliances,
such as hobs and ovens.
Unrestricted operation is possible if the
extractor hood is used in recirculating
mode – with activated carbon filter.
If the exhaust air is going to be
discharged into the open,
a telescopic
wall box should be fitted into the outside
wall.
