Important: To avoid the danger of
toxic fumes, please observe the
Warning and Safety instructions.
This is especially crucial when using
the rangehood at the same time as
another heating appliance which
relies on air from the same room.
The rangehood should be installed
according to local and national
building regulations. Seek approval
from the building inspector where
necessary.
Connection for air extraction
– 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
can 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.
– Only use rigid ducting fixed into
place.
– If flat ducting is being used, the
cross-section must not be smaller
than the cross-section of the exhaust
connection.
If exhaust ducting with a diameter of
less than 150 mm, or if flat ducting
or highly flexible ducting is used, the
noise level of the rangehood will
increase and extraction will be less
efficient.
– All ducting, pipework and fittings
must be of non-flammable materials.
– 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.
– Ensure that all connections are
strong and airtight.
