Important: To avoid the danger of
toxic fumes, please observe the
Warning and Safety instructions.
This is especially crucial when using
the cooker hood at the same time as
another heating appliance which
relies on air from the same room.
The cooker hood should be installed
according to local building
regulations. Seek approval from the
building inspector where necessary.
– Only use smooth pipes or flexible
hoses made from non-flammable
materials for the extraction ducting.
– When using an external motor, make
sure that the exhaust ducting is
sufficiently rigid. The external motor
can cause an underpressure which
could result in the exhaust ducting
distorting.
To achieve the greatest possible air
extraction with the lowest noise level,
please note the following:
– To ensure efficient air extraction, the
diameter of the exhaust ducting
should not be less than 150 mm.
– If flat ducting is being used, the
cross-sectional area must not be
smaller than the cross-sectional area
of the exhaust connection.
– The exhaust ducting should be as
short and straight as possible.
– Only use wide radius bends.
– The exhaust ducting should not be
kinked or compressed.
Connection for air extraction
– Ensure that all connections are
strong and airtight.
– Where ducting is horizontal, it must
be laid to slope away at at least 1 cm
per metre.
condensate cannot drain back into
the cooker hood.
– Only for ABLG 202: If the exhaust air
is to be ducted into the open air, the
installation of a telescopic wall vent
or roof vent (available as an optional
accessory) is recommended.
If the exhaust air is to be ducted into
a vent flue or chimney, the ducting
must be directed in the flow direction
of the flue or chimney.
Important
If the exhaust ducting is to run through
rooms, ceiling space etc. where there
may be great variations in temperature
between the different areas, the
problem of condensation will need to
be addressed. The exhaust ducting will
need to be suitably insulated.
This is to ensure that
