INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only metal
ductwork.
1. Decide where the ductwork will run between
the hood and the outside.
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.
4. Install a roof or wall cap. Connect 6" round
metal ductwork to cap and work back to-
wards hood location. Use duct tape to seal
the joints between ductwork sections.
INSTALL SUPPORT SYSTEM
1. Assemble the upper half of support frame to
the upper bracket and fix it by means #4
screws (1/8x3/8”).
2. Fix the gasket on the ductwork hole.
3. At hood location, install 2 X 4 cross framing
between ceiling joists using dimensions
shown.
4. Finish the ceiling surface. Be sure to mark
the location of the ceiling joists and cross
framing.
5. Fix the bracket to the ceiling by means of the
4 screws (1/4x2-3/4”) with 4 washers
(
ø 1/4”).
6. Make sure screws are driven into center of
joists and framing for maximum strength.
