Ducting
The ducting used must be fire retardant 125mm (5”)
in diameter. If possible duct through the wall at
the rear of the canopy or wall cabinet. For the
best performance use the shortest possible
duct run and the minimum number of bends.
Where flexible ducting is fitted 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 efficiency of
the hood could be impaired.
A flange spigot of a 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 flue must be of the room
sealed or balanced flue type.
If other types of flue or appliances are
fitted ensure that there is an adequate
supply of air to the room.
The cooker hood ducting (extraction
version) must never be connected to
central heating flues, radiators or water
heaters etc.
