Installing the Ductwork: Use galvanized
or aluminum duct in 6” round or 3-1/4” x
10” size, or combination of both. PVC duct
or locally approved piping should be used
if installing under a poured concrete slab.
Local building code must be followed in
specifying type and schedule of all duct used.
Note: Ductwork must be vented to outside.
Do not vent into a wall, ceiling, crawlspace,
attic or any concealed space. Always use
an appropriate roof or wall cap with damper.
Laundry-type wall caps should never
be used. For maximum efficiency use the
shortest and straightest duct run possible,
with as few fittings as possible.
For satisfactory
performance the duct run
should not exceed 100 feet equivalent length.
Refer to the table of equivalent lengths
(shown in installation instructions) for
various duct configurations.
