Danger of toxic fumes.
Please heed the "Warning and
Safety instructions" to avoid the dan-
ger of toxic fumes.
The cooker hood should be installed
according to local building regula-
tions. Seek approval from the build-
ing inspector where necessary.
– All ducting, pipework and fittings
must be of non-flammable material.
– The extraction ducting should be as
short and straight as possible.
– To ensure efficient air extraction the
diameter of the exhaust ducting
should not be less than 150 mm.
If exhaust ducting with a diameter of
less than 150 mm or flat ducting
were to be used, the noise level of
the cooker hood would increase and
extraction would be less efficient.
Only reduce the diameter of the
ducting if absolutely necessary, e.g.
where narrower ducting has already
been installed.
– Only use wide radius bends. Tight
bends reduce the air throughput of
the cooker hood.
– Only use smooth pipes or flexible
hoses made from non-flammable ma-
terials for extraction connection.

Connection for air extraction

– Where ducting is horizontal it must
be laid to slope away at at least 1 cm
per metre.
This is to ensure that condensate
cannot drain back into the cooker
hood.
– If the exhaust air is to be ducted into
the open air, the installation of a tele-
scopic wall vent is recommended.
– If the exhaust air is to be ducted into
a vent flue, the ducting must be di-
rected in the flow direction of the
flue.
