Wood framing channels are mainly used in residential homes. Consult a structural engineer to ensure you have
selected the correct mounting method for your building structure.
WARNING: The fan can weigh up to 120 lbs (54.4 kg).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.

1. Identify mounting location

CAUTION: Do not install the fan from a single beam or a conduit box.
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 using the Wood Frame Mounting Hardware as shown. The
brackets should be pointing inward. Torque 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.
