CAUTION: It is your responsibility to comply with all local and national codes and regulations regarding
mounting procedures and installation height!
CAUTION: The column on which the fan will be mounted must be verified as sucient to support the
weight of the fan.
Secure the wall/column supports to the column with the installer-supplied hardware listed below. Refer to the
appropriate illustration on the following page for your column mounting application.
Note: All hardware used to secure the wall/column mount supports is installer-supplied. Big Ass Fans cannot
provide specific installation details because of the wide variability of mounting surfaces, conditions, and fastening
methods. Consult a structural engineer to determine the required hardware. The table below provides a general
description of the hardware recommended for suggested column mounting applications.
Tighten the hardware to a torque sucient to support the weight of the fan, being careful not to deform the
column.
Note: The torque of the hardware depends on the grade of hardware and size of the fastener. The torque of the
nuts on the U-bolt is the responsibility of the installer, as this will vary by U-bolt size.
