If installation requires double angle irons, i.e., span is greater than 8 ft (2.4 m), proceed to step 4b.
CAUTION: The angle irons must be fastened to the roof structure at each end.
Fasten the angle irons to the roof structure mounting points at each end with customer-supplied Grade 8 hardware as shown. Do not
tighten the hardware until the fan has been mounted to the angle irons. Note: Big Ass Fans recommends orienting the angle irons
so that the horizontal legs are facing each other. Refer to the illustration below.
