into the fan. With some combinations of fan and
shutter, a portion of the opening may be blocked
by the platform. This will not effect the efficiency of
the fan. Fasten the platform to the joists and new
framing. (See fig. 2).
STEP 7. Center the plenum on the platform and
toe nail it in place. NOTE: WHEN TOE NAILING
PLENUM TO PLATFORM MAKE CERTAIN THAT THE
SIDES OF THE PLENUM REMAIN STRAIGHT AND
SQUARE OR THE FAN WILL NOT FIT PROPERLY.
STEP 8. To prevent Attic Air from entering the
plenum, tape all of the joints of the new framing,
platform and plenum with duct tape or aluminum
foil tape.

STEP 9. Place the fan on the plenum making sure
that the rubber isolation mount is in place between
the fan and plenum. DO NOT REPLACE SCREWS.
This is to permit the fan to “float” on the rubber
mount which helps reduce noise. (See fig. 4).
STEP 10. Install the flush mounted ceiling shutter
into the ceiling opening using the screws provided.
Caution should be taken not to effect the free
operating action of the shutter. (See figs. 3 & 4).
