DUCTWORK ARRANGEMENT
The downdraft vent is shipped with the
discharge outlet on the left side. It can be
changed to the right side to avoid interference
in routing the ductwork.
• To change the ductwork to the right side,
remove the screws holding the outlet panel to
the bottom of the vent.
• Remove and rotate the panel and fasten with
screws.
• The blower can be mounted in the cabinet or
under the floor. The blower will fit between floor
joists on 16
″
centers.
PLAN THE DUCTWORK
Prepare ductwork to vent to outdoors:
• Use the shortest and straightest duct run
possible.
• Duct run should not exceed equivalent length
of 150 feet. Refer to “Duct Fittings” chart to
calculate equivalent length for various duct
configurations.
• This downdraft blower system is designed for
use with 3

″
x 10
″
ductwork. It can be
transitioned to 6
″
round.
• Ductwork MUST be vented to the outside.
Never vent into a crawl space, attic or other
enclosed space.
