INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only steel 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 8" round steel ductwork to cap and work back towards hood location. Use duct tape to seal the joints between ductwork sections.
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.Position upper half of support frame so that the support frame opening is on the short side of the hood.
4.Secure the upper half of support frame to joists and cross framing with four screws pro- vided. Make sure screws are driven into cen- ter of joists and framing for maximum strength.
5.Adjust the overall height of the support frame. Loosen and
