Extraction (Ducted)
The cooker hood is more effective when installed in the
extraction mode (ducted to the outside).
Venting kits may be purchased through your local John
Lewis store, and must be evacuated through an outside
vent of ø125 (5ins) or ø150mm (6ins).
The ducting used must be manufactured from fire
retardent material conforming to the relevant British
Standard or DIN 4102-B1.
When the cooker hood is ducted to the outside
the charcoal filter must be removed.
Fitting the Ducting
• Fit the ø150mm (6ins) ducting to the spigot on top of
the hood body as illustrated.
• When using ø125mm (5ins) ducting fit item 9 and 10
on to the spigot on the top of the hood body as illus-
trated.
• For the best performance use the shortest possible run
of ducting and we recommend the use of rigid pipe in
preference to flexible hose as this will improve the flow
of air while reducing turbulence, which causes noise and
a loss of performance.
• 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 ducting when fitted in the extraction mode
must never be connected to central heating flues, radiators
or water heaters.
• Lift up the frame, fit the frame slots onto the screws
up to the slot end positions.
• Tighten the two screws and fasten the other two screws
provided with the hood.
Before tightening the screws completely it is possible to adjust
the frame by turning it. Make sure that the screws do not
come out of their seats in the slotted holes.

stand the weight of the hood and any stresses
caused by the occasional side thrust applied to
the device.
On completion, check that the base is stable,
even if the frame is subjected to bending.
