Curb installations must comply with local codes and should be done
in accordance with the established guidelines of the National Roof-
ing Contractors Association.
Proper unit installation requires that the roof curb be firmly and
permanently attached to the roof structure. Check for adequate
fastening method prior to setting the unit on the curb.
Full perimeter roof curbs are available from the factory and are
shipped unassembled. Field assembly, squaring, leveling and
mounting on the roof structure are the responsibility of the in-
stalling contractor. All required hardware necessary for the as-
sembly of the sheet metal curb is included in the curb accessory.

Sufficient structural support must be determined prior to
locating and mounting the curb and package unit.

Ductwork must be constructed using industry guidelines.
The duct work must be placed into the roof curb before
mounting the package unit. Our full perimeter curbs

Curb insulation, cant strips, flashing and general roofing
material are furnished by the contractor.
The curbs must be supported on parallel sides by roof members.
The roof members must not penetrate supply and return duct open-

NOTE: The unit and curb accessories are designed to allow vertical
duct installation before unit placement. Duct installation after unit
placement is not recommended.
