3. Installation
PNEG-1425 50" Galvanized Butterfly Fan 11
Installation of the Fan on a Vertical Plane
1. Position the fan in front of the opening from the inside of the building. Using a minimum of two (2)
people, lift fan housing into the opening.
2. Because of the design and operation of the butterfly flaps it is necessary to mount the fan
vertical regardless of the angle of the wall to which it is mounted. In order to accomplish this it is
recommended that a level be positioned vertical on the housing and shims (furring strips can be
used) be placed behind either the top or bottom mounting flanges until the fan is fully vertical.
(See Figure 3C.) Once you confirm the fan is setting vertical in the opening, fasten flanges to the
rough opening framework with the wood mounting screws provided. Failure to complete this step
can result in insufficient closure of the butterfly flaps. The fan housing should now be flush and level
inside of the framing.

Lifting Hazard. Single person lift could cause injury. Use two (2) or more people
or a mechanical lifting device to lift/move heavy equipment.
NOTE: Fan must be vertical.
