INSTALLING THE
DUCTWORK: INTERNAL
BLOWER
NOTE: To reduce the risk of fi re, use only
metal ductwork.
1. Decide where the ductwork will run
between the hood and the outside.
2. A straight, short duct run using a minimum
6" round duct (10" round duct for the dual
blower) will allow the hood to perform most
effi ciently.
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 cap. Connect round metal
ductwork to cap and work back towards
hood location. Use duct tape to seal the
joints between ductwork sections (Fig.4).
5. The blower can be rotated according to the
air outlet location. See Fig. 5 and 6.
