WARNING FIRE HAZARD
NEVER exhaust air or terminate duct work into spaces between walls, crawl spaces,
ceiling, attics or garages.
All exhaust must be ducted to the outside, unless using the recirculating option.
Use single wall rigid Metal ductwork only.
Fasten all connections with sheet metal screws and tape all joints w/ certified Silver
Tape or Duct Tape.
INSTALL THE DUCTWORK:
NOTE: 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 6" round metal ductwork to cap and work
back towards hood location. Use duct tape to seal the joints between ductwork
sections.
