STEP 2 INSTALL THE DUCTWORK

• The downdraft blower system is designed for use
with 3-1/4" x 10" ductwork. It can be transitioned to 6"
round.
• Ductwork MUST be vented to the outside – never in a
crawl space, attic or other enclosed space.
• 6" PVC duct should be used when installing under a
concrete slab.
Note: Local building code must be followed for
installation in specifying approved type and schedule
of PVC duct used.
Air
Flow
• DO NOT USE flexible plastic ducting.
• Always use appropriate roof or wall cap with
damper. Laundry type wall caps should never be
used.
• Use the straightest duct run possible.
• For satisfactory performance the duct run should not
exceed 150 ft. or its equivalent length when bends or
various fittings are used. Refer to the table of equiva-
lent lengths to calculate your installation.
• Install ductwork so the piece of duct nearest the
downdraft unit slots INTO the next piece of the duct.
Secure the joints with self-tapping screws and apply
duct tape around the joints to ensure an airtight seal.
