Curb installations must comply with local codes and should follow the established guidelines of the National Roong
Contractors Association.
Proper unit installation requires that the roof curb be rmly 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. The installing contractor is responsible for
eld assembly, squaring, leveling, and mounting on the roof structure. All required hardware necessary for the assembly of the
sheet metal curb is included in the curb accessory package.
• Determine sucient structural support before locating and mounting the curb and package unit.
• Duct-work 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 include duct connection frames to be assembled with the curb. Cantilevered-type
curbs are not available from the factory.
• Contractor furnishes curb insulation, cant strips, ashing, and general roong material.
• Support curbs on parallel sides with roof members. To prevent damage to the unit, the roof members cannot penetrate
supply and return duct openings.
Note: The unit and curb accessories are designed to allow vertical duct installation before unit placement. Duct installation
