INSTALL THE DUCTWORK
DUCTED HOODS ONLY
CAUTION: To reduce the risk of fire,
use only metal ductwork.
1. Decide where the ductwork will run
between the hood and the outside.
Fig. 6.
2. A straight, short duct run will allow
the hood to perform most efficiently.
3. Long duct runs, elbows, and transi-
tions will reduce the performance of
the hood. Use as few of them as pos-
sible. Larger ducting may be required
for best performance with longer duct
runs.
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.
