INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only
metal ductwork.
1. Decide where the ductwork will run be-
tween the hood and the outside. Fig. 6.
2. A straight, short duct run will allow the hood
to perform most efficiently.
3. Long duct runs, elbows, and transitions will
reduce the performance of the hood. Use
as few of them as possible. Larger ducting
may be required for best performance with
longer duct runs.
4. Install a roof or wall cap. Connect round
metal ductwork to cap and work back to-
wards hood location. Use duct tape to seal
the joints between ductwork sections.
INSTALL SUPPORT FRAME BRACKET
1. At the ceiling, mark center of desired range hood location.
2. Secure 2x4" cross framing around hood center. See Fig. 7 for dimensions.
Note: Framing must be firmly secured to support weight of hood. If joists
are cut, frame in using the same size lumber.
3. After framing, finish the ceiling surface. Mark center locations of joists and cross
framing on the interior side of the ceiling surface.
4. Using the installation template (supplied with installation instructions), align
template with joist and cross framing marks on the ceiling. Secure the template.
Note: Be sure the "control panel" marking on template faces the desired
direction before cutting.
5. Transfer location of support frame bracket mounting holes, duct and electrical
openings from template onto the ceiling.
6. Cut openings in ceiling surface and mount the support frame bracket with (4)
hex head lag bolts and washers. Fig. 8.
