Before installation, it is important
to read the information given on the
following pages as well as the
"Appliance dimensions" and the
"Warning and Safety instructions" at
the beginning of this booklet. This is
particularly crucial when using the
cooker hood at the same time as a
heating appliance that relies on
oxygen from the same room, which
could result in the build-up of toxic
fumes.
It is essential that the "Warning and
Safety" instructions are observed.
The cooker hood should be installed
according to local and national
building regulations. Seek approval
from the building inspector where
necessary.
Use smooth or flexible ducting made
from approved non-flammable
materials for exhaust 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 most efficient air
extraction with the lowest noise
levels, 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
section must not be smaller than the
cross sectional area of the exhaust
connection.
Connection for air extraction
– The exhaust ducting should be as
short and straight as possible.
– Only use wide radius bends.
– The exhaust duct must not be kinked
or compressed.
– Ensure that all connections are
strong and airtight.
Remember that any constriction of
the air flow will reduce extraction
performance and increase operating
noise.
If the exhaust is ducted through an
outside wall, a telescopic wall vent or
a roof vent (available as an optional
accessory) is recommended.
If the exhaust air is to be ducted into
a vent flue, the ducting must be
directed in the flow direction of the
flue.
When ducting is horizontal it must be
laid to slope away at at least 1 cm
per metre. This is to ensure that
condensate cannot drain back into
the appliance.
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
