INSTALL THE DUCTWORK
(DUCTED HOODS ONLY)
! CAUTION: 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. 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
towards hood location. Use duct tape to seal the joints between ductwork sec-
tions.

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. Secure the support frame bracket to joists and cross framing with four screws
provided (6x70mm) and four washers (D. 6.4mm). Make sure screws are driven
into center of joists and framing for maximum strength. Be careful, because the
position of the bracket determines the final position of the apparatus: the side with
the slot B corresponds to the side opposite the controls. Fig. 5.
4. Fix the support frame to the support frame bracket with (4) 3.9x9.5mm mounting
screws. Fig. 6.
5. Adjust the overall height of the support frame. Loosen and re-tighten the 4 screws
in the height adjustment slots as necessary.
