When determining fan spacing/fan layout, keep in mind that the fan requires ¼" clear space from the mounging
flange so the Shutter Clips have room to rotate, to allow the shutter to be removed and reinstalled in the fan without
interference. Also, the sides of the fan also require 3¾" clearance for the Wind Kit Bracket to be installed. If the
fans are to be installed side-by-side with the Wind Kit Brackets adjacent to each other, the minimum fan spacing is
98" Center-to-Center. See Figure Below.
