INSTALL THE DUCTWORK
Only for Ducted configuration.
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. At hood location, install 2 X 4 cross framing
between ceiling joists using dimensions
shown.
2. Finish the ceiling surface. Be sure to mark
the location of the ceiling joists and cross
framing.
3. Only ductfree configuration:
remove the height adjustment slots from
the support frame and separate the upper
half from the lower half. Fix a 6" round steel
duct to the duct connector of the ductfree
plenum. Insert the ductfree plenum complete
with duct into the upper half of support frame
so that the air outlets match openings A of
the support frame. Now fix the ductfree
plenum with the four screws B. Fit the upper
