Duc twork
Prepare the ductwork to vent to the outdoors.
• Plan the shortest and straightest route for venting exhaust
to the outdoors.
• The maximum permissible length for the duct run is 150 feet.
• Use metal ductwork only.
• The downdraft blower system is designed to use 3-1/4" x 10"
duct. It can be transitioned to 6" round.
• Install a wall cap or roof cap with damper at the exterior
opening. Order the wall cap and any transition needed
in advance.
Venting options
The downdraft vent is shipped with the discharge outlet
pointing straight down and can be changed to a left- or right-
side discharge. For even more flexibility, the entire blower and
mounting plate can be adjusted 3-1/2" to the left or right sides.
