Installing your Cooker Hood
5
Your new Cooker Hood can be installed either
for recirculation or extraction through an
outside wall. (All fitting supplied)
Installation for Recirculation:
If it is not possible to exhaust to the outside,
the hood can be used to filter and recirculate
the air (Fig.1).
Your hood can be fitted with a carbon filter
(optional extra) to remove odours (for fitting,
see page 11).
The carbon (charcoal) filter can then be fitted.
NOTE: The hood is more efficient in the
exhaust mode, therefore this position
should be selected during the warmer
months of the year when no heating is
being used. When the room is being
heated, if the recirculation position is
selected heat will not be wasted.
To obtain the best performance it is
advisable to switch on the hood a few
minutes before you start cooking and leave
it running approximately 15 minutes after
finishing.
Installation for Extraction:
This method is recommended if at all possible.
Fumes and grease laden air are drawn into the
underside of the hood and expelled outside
the kitchen. The air can be expelled either
upwards through a ventilating shaft (Fig.2) or
directly through a wall to the outside (Fig.3).
Ducting will be required if the Cooker Hood is
mounted away from the outside vent.
IMPORTANT: The exhaust air must not be
expelled through a smoke or waste-gas
chimney which is in use or through a shaft
used for ventilating rooms or into the
cavity of a cavity wall.
If the room contains a flued fuel burning
appliance, such as a gas or oil fired central
heating boiler, which is not of the ‘Balanced
Flue’ type, you should make sure that there
is adequate air inlet into the room at all
times so that fumes from the boiler are not
drawn back into the room by the Cooker
Hood.
NOTE: All installations must comply with
local authorities and building regulation
requirements for the discharge of exhaust
air into the atmosphere.
