installation. Use a utility knife or sheetrock saw and

back from shutter opening. This is to accommodate
additional framing to support the joists that have
been cut. (See fig. 1).
STEP 3. Frame the opening using lumber EQUAL
TO THE EXISTING JOISTS. Attach the new framing to
the existing joists. Before fastening, make sure that
the existing joists that were cut DO NOT sag below
the uncut joists and new framing. (See fig. 2).
STEP 4. If additional framing or blocking is needed to
support the shutter, install it at this time. (See fig. 4).
STEP 5. Remove the two (2) screws that secure
the fan to the plenum. Pass the fan and plenum into
the attic through the framed opening in the ceiling
and set them aside at this time.
STEP 6. Build a platform to support the fan using
lumber, plywood or other material a minimum of

thick. The platform must be constructed so that
it supports all four sides of the fan, and should be
wide enough to prevent Attic Air from being drawn
LOCATION OF FAN: The most logical place to
locate your whole house fan is near the central part
of the house. Check attic area to be certain there
is a clearance space above the fan equal to the
diameter of the fan blade. Inspect the area where
the fan is to be installed. The area must be free of
electrical wiring and pipes.
CAUTION: DO NOT OPERATE THIS FAN UNTIL
