Align upper support frame with holes in ceiling. Mount
the upper support frame to the ceiling using four "A"
screws (for sheet rock only). Make sure that the upper
support frame is securely fastened to the joist or
support in the ceiling. Attach support frame to ceiling
using anchors recommended for your type of ceiling:
• Sheet rock ceiling: Attach support frame to ceiling
joists or stud blockings if possible. If ceiling joists or
stud blockings are not available, it is required to build
a supporting structure behind the sheet rock for best
weight support.
Concrete ceiling: Use concrete sleeve anchor.
•
Wood ceiling: Use at least 4" long wood screws.
•
Position the support frame extensions at the inside
corners of the support frames, adjust and mark each
support frame extension as necessary to achieve the
proper height for the range hood to be set away from
the cook top.
Fasten the support frame extension onto the lower
support frame using four "B" bolts and "C" nuts as it is
shown in Figure 3. Repeat this step for rest of the
support frame extensions. IMPORTANT: Always use first
and second holes on the support frame extensions.
Calculate the height of the duct tube and extend
approximately 6 inches longer than required, connect
the upper end of the duct tube to the vent system.
Position the lower support frame with support frame
extensions to the upper support frame, fasten each
extension with four "B" bolts and "C" nuts as shown in
Figure 3.
