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. Larger ducting
may be required for best performance with
longer duct runs.
4. Install a roof or wall cap. Connect round
metal ductwork to cap and work back to-
wards hood location. Use duct tape to seal
the joints between ductwork sections.
INSTALL MOUNTING
BRACKETS
1. Construct wood wall framing that is flush
with interior surface of wall studs.Make
sure:
a) the framing is centered over installation
location.
b) the height of the framing will allow the
mounting brackets to be secured to
the framing within the dimensions
shown.
2. After wall surface is finished, secure mount-
ing brackets to framing using dimensions
shown.
