INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only
steel 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 8" round
steel ductwork to cap and work back towards
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. Position upper half of support frame so that
the support frame opening is on the short
side of the hood.
4. Secure the upper half of support frame to
joists and cross framing with four screws pro-
vided. Make sure screws are driven into cen-
ter of joists and framing for maximum
strength.
5. Adjust the overall height of the support frame.
Loosen and re-tighten the screws in the
height adjustment slots as necessary. Note
that the hood height is 10¼” and that the
bottom of the hood must be 24” min. and 30”
max. above the cooktop.
