Install Mounting Bracket - Broan Best K3139 Manual De Instrucciones

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
BRACKET
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 bracket to be secured to the
framing within the dimensions shown.
2. After wall surface is finished, secure mount-
ing bracket to framing using dimensions
shown.
INSTALL THE
HOOD
1. Hang the hood from the
bracket through the
rectangular cut-out on
the back of the hood. Cut-
out is larger than the
bracket to allow for
horizontal adjustment.
The bottom of the hood
should be 24" to 30"
above the
surface.
2. Secure the hood with
mounting screws. Use
drywall anchors, provided, if wall studs or framing are not available.
