2. Remove housing temporarily, and pound nails partially into
joists at all four marked locations.
3. Hang housing from nails. Use measuring guides on corners of
housing to check if unit will be flush with finished ceiling. Pound
nails tight. For wide joist centers: A #8 x 3/8 self-tapping screw
can be used to join extended brackets together and create a
rigid mount. To ensure a noise-free mount, crimp the bracket
channels tightly around mounting brackets.
4. Snap the damper/duct connector onto housing. Make sure that
tabs on the duct connector lock in housing slots and that gravity
closes damper.
5. Install 4” round duct and extend duct to outside through a roof
or wall cap. Check damper to make sure that it opens freely.
Tape all duct connections to make them secure and air tight.
