Tools needed

Big Ass Fans recommends gathering the following tools prior to beginning installation.

Mechanical installation

Standard wrench set

Standard socket set and ratchet

Torque wrench capable of 40 ft·lb (54.2 N·m)

Standard allen wrench set

To ensure the fan is properly mounted, the fan must always hang plumb to the ground and the yoke must be installed using the bolt

holes at the widest locations possible. To accommodate building structures on which the standard upper yoke does not allow the fan to

properly orient itself, the 90-Degree Offset mount should be purchased.

The example below shows one situation in which the 90-Degree Offset mount must be used so that the fan hangs plumb to the ground

and the widest stance for the upper yoke is ensured. If you are uncertain of your roof pitch or do not have the correct mount to properly

hang your fan, consult a structural engineer or contact Big Ass Fans Customer Service at 1-877-BIG-FANS.
