Extraction
The charcoal fi lters are not required in
this mode and should be removed. To
do this reverse the procedure described
in Inserting the 'Charcoal Filters'.
Ducting
The ducting used must be fi re retardant
125mm (5") in diameter. If possible
duct through the wall at the rear of the
canopy or wall cabinet. For the best
per for man ce use the shortest possible
duct run and the minimum number
of bends. Where fl exible ducting is
fi tted it should not be turned through
very tight bends as this may impair
the performance of the hood. It is
recommended a maximum length of
3m, to be installed, to be reduced
1m for each 90° bend installed in the
ducting run. If the distance is greater
than 3m the effi ciency of the hood could
be impaired.
A ducting collar of 120-125 mm (5") is
supplied for attaching to ducting if you
are using the appliance in the extraction
mode.
If the room where the cooker hood
is to be used contains a fuel burning
appliance such as a central heating
boiler, then its fl ue must be of the
room sealed or balanced fl ue type.
If other types of fl ue or appliances are
fi tted ensure that there is an adequa-
te supply of air to the room.
The cooker hood ducting (extraction
version) must never be connected
to central heating fl ues, radiators or
water heaters etc.
