Connection for air extraction
Extraction connection should only
be carried out in accordance with
building regulations.
Danger of toxic fumes
Please heed the “Warning and
Safety” instructions to avoid the
danger of toxic fumes. Follow the
advice in the section ,,Warning and
Safety instructions“ very carefully.
The cooker hood should be in-
stalled acording to local regulations.
Seek approval from the buildings in-
spector where necessary.
Air extraction ducting
– 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 100 mm.
The use of flat ducting also reduces the
air extraction efficiency.
The use of extraction ducting with a
diameter of less than 100 mm and of
flat ducting increases the noise level
of the cooker hood.
– 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.
– When ducting is horizontal it must be
laid to slope away at a minimum of 1
cm per metre, to ensure no conden-
sate drains into the appliance.
– 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.
