Extraction
The charcoal fi lter is not required in this mode
and should be removed.
Ducting
The ducting used must be Ø150mm (6ins), or
Ø125mm (5ins) in diameter.
If possible duct through the wall immediately
above the hood body.
For the best performance 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 recommenmded a maximum length of 3
metres, to be installed, to be reduced 1 metre for
o
each 90 bend installed in the ducting run.
If the distance is greater than 3 metres the
effi cency of the hood could be impaired.
The diameter of the ducting spigot on the top of
the hood body item 1 is Ø150mm (6").
When using Ø125mm (5") ducting it will be
necessary to install the ducting adapter item 9
to the Ø150mm (6") outlet on the top of the hood
body and the Ø120mm to 125mm ducting collar
item 10 (supplied).
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 adequate
supply of air to the room.
The cooker ducting (extraction mode)
must never be connected to central
heating fl ues, radiators or water heaters
etc.
Electrical Connection and Working
Test
Before fi tting the chimney to the canopy make the
electrical connection as described in the section
