INSTALL THE DUCTWORK
(DUCTED HOODS ONLY)
!
WARNING: 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 sections.
