Installing Roof Exhauster Assembly
The roof exhauster assembly replaces one of the roof flashing panels and allows for the roof exhauster to
be installed.
Before You Begin
IMPORTANT: Determine the location of the roof exhauster and remove the existing roof flashing panel at
this location. Install the peak-to-exhauster ladder kit next to the roof exhauster on the next
available rib. The location of the roof exhauster can vary. It should be installed in a location
that is free of obstructions, where it does not interfere with any other accessories on the
roof.
NOTE: The roof exhauster kit is shipped with additional parts. The following part numbers will not be used
on 40-series bins:
MIS-6703, MIS-6706, MIS-6707, MIS-6805, MIS-6810, MIS-6811, CRP-4793 and CRP-5262.
1. Before lifting the roof exhauster into place, apply strips of sealing caulk (F) along the ribs of each roof
panel and on each roof flashing as shown.
2. Use an appropriate lifting device and qualified personnel to hoist the roof exhauster assembly (D)
into place.
3. Install flange bolts (G) and flange nuts (E), securing the roof exhauster assembly (D) to the roof
panel.
NOTE: Do not tighten flange bolts until all components have been installed.
4. Apply a strip of sealing caulk (C) along the mating surface of the roof exhauster assembly (D) and
roof exhauster flashing (A).
NOTE: Roof exhauster flashing (A) must be bolted on the top surface of the exhauster mounting
plate.
5. Install flange bolts (B) and nuts (E), securing the roof exhauster flashing (A) to the roof exhauster
assembly (D).
6. Tighten all hardware to the recommended torque specification. See Bolt Torque Specifications, page
28 .
