Preparations of Ductwork and Location
NOTE: TO AVOID DAMAGE TO YOUR
HOOD, PREVENT DEBRIS FROM
ENTERING THE VENT OPENING.
- Decide the location of the venting pipe from
the hood to the outside. Refer to Figure 1.
- A straight, short venting run will allow the
hood to perform more efficiently.
- Try to avoid as many transitions, elbows,
and long run as possible. This may reduce
the performance of the hood.
- Temporarily wire the hood to test for proper
operation before installing.
-
Important: Peel any protective film off the hood
-
Use duct tape to seal the joints between pipe
sections.
Telescopic Stack Installation
1. Mark centerlines of cook top or range on
ceiling above. Use centerlines marked on
ceiling to position the mounting template
as shown in Figure 2.
2. Remove and save template. Cut and
remove ceiling drywall. Install 2” x 4” cross
framing lumber (not provided) between
ceiling joists. Refer to Figure 3. Consult a
professional if you have difficulty or your
installation is unique.
3. Finish the ceiling surface. Be sure to mark
the location of the ceiling joists and cross
framing, or replace the mounting template
in the position of the ceiling joists & cross
framing.
4. Attach the telescopic stack to the ceiling
and securely fasten to the joists and cross
framing with eight screws (provided) as
shown in Figure 3. Make sure screws are
driven into center of joists and cross
framing for maximum support.
5. Adjust the telescopic stack using reference
F calculated in Table 1 and measurements
on page 12. Tighten from the side with four
(4x8 mm) screws (provided) as shown in
Figure 3.
