Roof Curb Installation
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 roof-
ing 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.
