14 Mounting Method: Wood Frame
WARNING: The fan should not be installed unless the structure on which the fan is to be mounted is of sound
construction, undamaged, and capable of supporting the loads of the fan and its method of attachment. A structural
engineer should verify that the structure is adequate prior to fan installation. Verifying the stability of the mounting
structure is the sole responsibility of the customer and/or end user, and Big Ass Fans hereby expressly disclaims any
liability arising therefrom, or arising from the use of any materials or hardware other than those supplied by Big
Ass
Fans
or otherwise specified in these installation instructions.
CAUTION: Do not install the fan where it will be continuously subjected to external air forces, such as from high winds or
HVAC system. Big Ass Fans recommends installing the fan at least 2x the fan diameter (center of fan to equipment) away
from any HVAC discharge unit; however, it is the installer’s responsibility to verify the safe performance of the fan when
operated in the intended environment.
CAUTION: Do not install the fan from a single beam or a conduit box.
CAUTION: Ensure the mounting location will not expose the fan to direct contact with water unless the fan is labeled,
“Suitable for use in wet locations.”
1. Identify mounting location
Locate the area on the beams from which the fan will hang. Big Ass Fans recommends mounting the fan so that the airfoils are at least
10 ft (3 m) from the floor.
The center-to-center distance between the two beams between which the fan will hang cannot be greater than
24 in (61 cm).
2a. Fasten brackets (to vaulted ceiling beams)
Fasten the brackets to the roof structure mounting points at each end with the Mounting Hardware as shown. The brackets should be
pointing inward. Torque the bolts to
25 ft·lb (33.9 N·m)
.
Using a level and carpenter’s square, ensure the mounting brackets are level and the opposing holes are concentric.
