MOUNTING STRUCTURE: CONCRETE
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!
ATTENTION
The following instructions are merely a recommendation for hanging the Yellow Jacket
®
from the building
structure. You must consult a structural engineer to determine the best method for mounting your fan.
Big Ass Fans is not responsible for installing the fan in concrete or to a flat surface. Consult a structural
engineer to determine if the flat surface is suitable for mounting the fan.
Yellow Jacket can be hung from a concrete ceiling using the Yoke Washer Assembly Kit.
Adhere to the below recommendations and guidelines when mounting Yellow Jacket to concrete.
• Big Ass Fans does not supply angle irons or anchor bolts. Select mounting hardware that is of sucient strength
to support the weight of the fan. Big Ass Fans recommends using 1/4” Dia. Hilti Kwik Bolt 3 Mechanical Anchors
with a minimum embedment depth of 1-1/8”.
• Avoid placing the anchors near concrete edges. Refer to the anchor manufacturer’s specifications for strength
reduction guidelines near edges.
• Ensure anchor spacing satisfies the anchor manufacturer’s specifications. If there are existing anchors in close
proximity to the new anchors, ensure that the spacing requirements of the existing anchors are satisfied.
• If anchoring the fan to reinforced concrete beams, verify the location and depth of the reinforcing steel by using
a non-destructive testing method, such as using the HILTI Ferrodetector, to avoid damaging the steel.
• If anchoring the fan to a concrete slab through fluted metal decking, check the anchor manufacturer’s
specifications for anchor placement limitations. Flute spacing may require a longer angle iron bracket to span
across the flute spacing. Do not connect all the anchors to one flute. A minimum of two flutes must be used.
• Verify that the concrete is at least the minimum thickness required by the anchor manufacturer.
• Avoid installing the fan in locations with the following characteristics: Exposed reinforcing steel; spalling or
chipping; cracks; or discoloration of concrete (i.e., rust stains) or eorescence. Also avoid locations that have a
hollow sounding response if tapped lightly with a hammer.
