WHERE TO INSTALL YOUR FAN
Before beginning installation, check that the building structure and fan location meet Big Ass Solutions’ safety
guidelines by confirming the below requirements.
☐ Fans mounted on fabricated I-beams, which are common in steel buildings, could cause the beam to flex and
the fan to move significantly during operation. If this flexing causes a clearance problem, we suggest installing
the I-Beam Stabilizer Kit. Contact Customer Service for more information.
☐ The fan’s lateral movement must be secured using guy wires if the fan’s extension tube is 4 ft (1.2 m) or longer
or if the mounting structure requires it. If the fan is close to any building fixtures it is recommended to secure
the fan with guy wires as a safety measure.
☐ The fan must be installed so that it is plumb to the ground
☐ All fan parts must be ≥ 2 ft (61 cm) from all obstructions. The fan installation area must be free of obstructions
such as lights, cables, sprinklers, or other building structure components.
☐ The fan must be installed so that it is ≥ 10 ft (3 m) above the finished floor.
Clearance guidelines
If your fan application does not meet these requirements, contact Customer Service to discuss alternative
installations or other fan options.
General clearance
☐ Multiple fans must be spaced at a center-to-center distance that is no less than 2.5x the fan diameter.
☐ The fan must be installed so that it is ≥ 10 ft (3 m) above the finished floor.
Ceiling clearance
The fans must be installed at the distance listed below according to your fan size. The distance of the fan from the
ceiling should be measured from the top of the winglets to the ceiling.
Fan Diameter Distance from Ceiling
8–14 ft (2.4–4.3 m) 5 ft (1.5 m) *
16–18 ft (4.9–5.5 m) 6 ft (1.8 m) *
20–24 ft (6.1–7.3 m) 7 ft (2.1 m) *
*If your fan includes Powerfoil Plus winglets, add 1 ft (30 cm) to the distance to the ceiling.
