FIXING THE FRAME
• Loosen the two screws fastening the lower chim-
ney and remove this from the lower frame.
• Loosen the two screws fastening the upper chim-
ney and remove this from the upper frame.
If you wish to adjust the height of the frame, proceed
as follows:
• Unfasten the metric screws joining the two col-
umns, located at the sides of the frame.
• Adjust the frame to the height required, then re-
place all the screws removed as above.
• Insert the upper chimney stack from above, and
leave it running free on the frame.
• 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 provi-ded 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.
• The frame mountings must be secure to withstand
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.
