Now take either your wood screws or bolts
depending on your set-up and screw all four
into the pilot holes and leave 1/4" of the
heads exposed.
Next install a UL or CSA listed strain relief
in the wiring box so that the screws can
be tightened after the chimney support is
attached to the ceiling.
Now lift the chimney support into it's nal
position and feed the electrical supply through
the strain relief.
Next position the chimney support so that
the large end of the keyhole slots are over
the ceiling attachment screws or bolts. Then
push the chimney support so that the bolts
are in the neck of the slots. Tighten all four
screws or bolts securely.
• 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.
