INSTALL THE DUCTWORK
IPB9IQ Series
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.
4. Install a roof or wall cap. Connect 10" round
metal ductwork to cap and work back
towards hood location. Use duct tape to
seal the joints between ductwork sections.
