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.
• The frame mountings must be secure to with-
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.
• In all cases where the ceiling is not strong
enough at the suspension point, the installer
must provide strengthening using suitable
plates and backing pieces anchored to the
structurally sound parts.
Extraction
The cooker hood is more effective when used in the
extraction mode (ducted to the outside).
Venting kits may be purchased through your retailer
or DIY store, and must be ducted to an outside vent
of Ø125mm (5") or Ø150mm (6").
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 perform-
ance of the hood.
It is recommended a maximum length of 3 metres
with one bend, to be installed, to be reduced metre
for each 90o bend.
If a distance is greater than 3 metres the effi ciency of
the hood could be impaired.
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 fi lter must be removed.
