Curb installations must comply with local codes and should follow the established guidelines of the National Roofing 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. The installing contractor is responsible for
field 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 sufficient 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, flashing, and general roofing 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 after
unit placement
is not recommended.
See the manual shipped with the roof curb for assembly and installation instructions.
