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 to- wards 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 lag bolts provided (6x70mm) and four washers (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 hood: the side with the slot B corresponds to the controls side. Fig. 2.
