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.
– 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 effi-
cient.
Only reduce the diameter of the duct-
ing 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.
– Where ducting is horizontal it must
be laid to slope away at at least
1 cm per metre.
This is to ensure that condensate can-
not 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.
