Roof Exhauster Placement
The figure shown is the recommended roof exhauster placement on the 135' bin. A Z-shape reinforcement
piece (CRP-6447) is sent with 135' roofs with exhausters. The reinforcement piece should be placed
roughly 28.00" from the middle of the upper roof beam splice. That dimension is taken from the upper
face of the Z-reinforcement piece. The second from the top hole of the roof exhauster support angle should
be line up with the C1 Z-collar. Two (2) 3/8" diameter holes should be drilled through the roof panel and
into the C1 Z-collar on each side of the exhauster housing. The exhauster should be fastened with 5/16"
hardware. Next the Z-reinforcement part should be placed under the lowest hole on the roof exhauster
support angle. The Z-reinforcement (CRP-6447) should be bolted to the roof beam and bolted to the
exhauster support angles. Four (4) holes will need to be drilled through the roof beams, Z-reinforcement
and roof panel to attach with 5/16" hardware. NOTE: Caulking will be needed at any locations of drilling
or cutting of the roof panels.
Also included is tubing for bracing the roof exhauster housing to the roof panels. Bracing angle and
location is determined by the installer. Care needs to be taken not to interfere with any other equipment
on the roof.
