Danger of toxic fumes.
Please heed the "Warning and
Safety instructions" to avoid the
danger of toxic fumes.
The cooker hood should be in-
stalled according to local building
regulations. Seek approval from the
building inspector where necessary.
Connection for air extraction
– 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 125 mm.
The use of flat ducting also reduces
the air extraction efficiency.
The use of extraction ducting with a
diameter of less than 125 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 or flexible pipes
made from non-flammable materials
for extraction connection.
When ducting is horizontal it must be
laid to slope away at 1 cm per metre, to
ensure no condensate 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.
Connection for air extraction
– 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.
