54" Galvanized Slantwall Fan
3. Installation Specifications
Construct the opening frame to the correct size (63-3/4" L x 61-3/4" W) as illustrated in the
Figure 3A
.
Figure 3A
The framing must be able to support the weight of the fan assembly. Ensure the load-bearing portion of
the bottom sill is rigid and properly supported. Position the fan in front of the opening from the inside. Using
at least two (2) people, lift fan housing into the opening. Fasten flanges to framework with the wood
mounting screws provided. Check the fan for vertical position before screwing flanges down. The fan
housing should be flush and level inside of the framing.
IMPORTANT: When installing more than one fan, maintain a minimum of 13" between rough openings to
ensure clearance of cones outside the buildings. The cone’s largest diameter is 68" and
allowances must be made to keep the cones separated. If not sure of sufficient clearance,
contact your local dealer for more information.
