Install the Ductwork

Use minimum 26 gauge galvanized or 24 gauge aluminum duct in 6″ round or 31⁄4″ x 10″ size, or a combination of both. PVC duct should be used if installing under a poured concrete slab. DO NOT use flexible plastic ducting.

■Always use an 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 if bends or other various fittings are used. Refer to table of equivalent lengths for various duct configurations.
