WARNING
!
The ceiling must be able to hold at least 265 lb weight, and the thickness of the ceiling must be at least 1¼".
4. INSTALL CEILING SUPPORT
1. Modify ceiling stucture at hood location. Install 2 x 4 cross framing between
ceiling joists using dimensions shown (
Fig. 1
). Make sure framing does not
interfere with electrical outlet box opening in ceiling mounting plate.
2. Finish ceiling surface. Be sure to mark the location of the ceiling joists and
cross framing. Bring house wiring through finished ceiling.
3. Remove cover from electrical outlet box on ceiling mounting plate. Install a UL
approved wire clamp (not included) on top of mounting plate. Run house wiring
through wire clamp into electrical outlet box. Tighten the wire clamp to secure
house wiring cable to mounting plate/electrical box.
4. Place the included installation template sheet on the ceiling and drill 12 holes in
the ceiling (
Fig. 2
). Refer to installation template side marked “front” to position
the mounting plate at the desired hood location. Secure mounting plate to the
ceiling using (12) M6 x 40 mm mounting screws. Make sure screws are driven
into the center of the framing for maximum strength.
NOTE: For a concrete ceiling, use the 8 included concrete bolts (evenly
distributed).
