MOUNTING STRUCTURE: COLUMN

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. 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 your responsibility to comply with all local and national codes and regulations regarding

mounting procedures and installation height!

The safety cable must be installed if mounting the fan to a column.

Yellow Jacket

can be mounted to a column that is part of the existing building structure. The following instructions

are merely a recommendation for mounting the Yellow Jacket on a column. Consult a structural engineer to

determine the best method for mounting your fan.

1. Prepare angle irons

Note: All hardware (including angle irons) 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.

Cut each angle iron to the appropriate length using the width of the column, round or ﬂanged (ﬂange or open-

ﬂange side), as a reference.

Drill a Ø9/16” hole on each end of the angle iron 3/4” (1.9 cm) from the edge of the column. Refer to the table and

illustration below. Repeat the above process on all angle irons.
