INSTALL THE DUCTWORK
(DUCTED INSTALLATION ONLY)
NOTE: To reduce the risk of fire, use only metal ductwork.
1. Decide where the ductwork will run between the hood and
the outside. (Fig. 1)
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 wall cap or roof cap (sold separately). Connect metal
ductwork to cap and work back towards the hood location. Use
2" metal foil duct tape to seal the joints between ductwork
sections.
OPTIONAL LINERS
For installations where the power module is less than 30"
above cook top, it is recommended that the power module be
mounted into a metal liner. This will allow easier cleaning and
provide protection to the cabinetry. Refer to table at right to find
the liner model corresponding to the cabinet style and width.
Visit www.broan.com or www.broan.ca to view specific model
information.
PREPARE THE CABINET
NOTES: A. The power module has to be installed inside the
cabinet, at minimum 1" from the rear wall. If
installing with one of the optional liners, use it as
a template to cut the hole in the bottom of the
cabinet.
B. The internal height of cabinet has to be minimum 16".
C. The hood should be mounted centered over the
cook top burners.
D. For cabinet without bottom, go to Alternate
mounting in INSTALL THE POWER MODULE
section on next page.
1. Cut a hole in the bottom of the cabinet, using the
dimensions shown (Fig. 2), or use the optional liner as a
template.
2. Secure 2 wood blocks having 2½" minimum height x 10¼"
long (not included) inside the cabinet, on left and right sides
of the hole, flush to the edges (Fig. 3).
3. Secure the optional liner (Fig. 4) using 4 mounting screws
(included with the liner).
