end. Shim as required and secure curb before installing flashing. Flashing is
field supplied.
If Option CJ50 or CJ49 curb was ordered to arrive prior to the heater, it will be
identified by the following P/N's. Verify the appropriate P/N before installing the
curb.
Before placing the unit on the curb, apply 1/4" x 1-1/4" foam sealant tape to
both the top surface of the curb sides and the top surface of the perimeter of
the duct opening(s), being sure to make good butt joints at all corners.
Option CJ50 and CJ49 curbs should only be used for the Models and Sizes for
which they are designed. The supply duct panels are insulated so should not
be used in an installation that prohibits insulation in the supply duct.
