a. The ductwork can be attached directly to the factory-provided flanges around the unit's
supply and return air openings. Be sure to use flexible duct connections at the unit.
b. For "built-up" curbs supplied by others, gaskets must be installed around the curb perimeter
flange and the supply and return air opening flanges.
If a "built-up" curb is provided by others, keep in mind that these commercial rooftop units do
not have base pans in the condenser section.
If this is a REPLACEMENT UNIT keep in mind that the CURRENT DESIGN commercial rooftop
units do not have base pans in the condenser section.
Trane roof curbs are recommended. If using a non-Trane roof curb with right-angle return
airflow approaches to a return fan inlet, a rigid, solid flow baffle wall should be installed across
the full width of the roof curb return airflow path in the position shown in
reduce potential airflow disturbances at the return fan inlet that could contribute to unusual
return fan noise.
