If the cooker hood is used at the
same time as a heating appliance
that relies on oxygen from the same
room, there is a risk in certain
circumstances of toxic fumes
building up.
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.
The cooker hood is fitted with an
exhaust connection of 150 mm.
Use smooth or flexible ducting made
from approved non-flammable
materials for exhaust ducting.
To achieve the most efficient air
extraction with the lowest noise levels,
please note the following:
– The cross-section of the exhaust
ducting must not be smaller than the
cross-section of the exhaust
connection (see "Appliance
dimensions").
– The exhaust ducting should be as
short and straight as possible.
– Only use wide radius bends.
– The exhaust ducting must not be
kinked or compressed. When
selecting the exhaust ducting, ensure
that it is rigid enough to retain its
shape during operation.
– Ensure that all connections are
strong and airtight.
Connection for air extraction
Any constriction of the airflow 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 flue, the ducting must be directed in
the flow direction of the flue.
Where 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 cooker hood.
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.
