Mounting Structure: I-Beam
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 mounting. 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: It is not recommended to mount a Big Ass Fan to a fabricated I-beam. Do not direct mount the fan to an I-beam.
The I-beam on which the fan will mount must be part of the existing building structure.
CAUTION: Install the spacers only if the thickness of the I-beam flange exceeds 3/8” (1 cm). The mounting holes on the
spacer are closer to one edge than the other. Make sure this edge of the spacer is facing the I-beam.
CAUTION: Before beginning installation, confirm that you have the appropriate mount for your roof pitch.
WARNING: Ensure there are no persons below the fan unit during installation!
1. Measure I-beam width
Measure the flange width of the I-beam from which the fan will be hung. Select the upper yoke mounting holes that match the flange
width of the I-beam.
