1, Decide where the ductwork will run between
the hood and the outside.

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
stee! ductwork to cap and work back towards
hood location. Use duct tape to seaI the joints
between ductwork sections.
