Roof Curb and Ductwork
The roof curbs for W_HE casings 2 through 9 units consists
of a "full perimeter" enclosure to support the unit.
Before installing any roof curb:
1. Verify that it is the correct curb for the unit,
2. Verify that it includes the necessary gaskets and
hardware,
3. Verify that the purposed installation location provides
the required clearance for proper operation.
4. Insure that the curb is level and square. The top surface
of the curb must be true to assure an adequate curb-to-
unit seal.
Step-by-step curb assembly and installation instructions
ship with each Trane accessory roof curb kit. Refer to the
applicable sections in the current edition of RT-SVN14*-EN
for W_HE casings 2 through 9. Follow the instructions
carefully to assure proper fit-up when the unit is set into
place.
Note:
To assure proper condensate flow during
operation, the unit (and curb) must be as level as
possible. The maximum slope allowable for
rooftop unit applications is 4" end-to-end and 2"
side-to-side excluding WSHE. Units with steam
coils (WSHE's) must be set level!
If the unit is elevated, a field constructed catwalk around
the unit is strongly recommended to provide easy access
for unit maintenance and service.
Recommendations for installing the Supply and Return Air
ductwork joining the roof curb are included in the curb
instruction booklet. Curb ductwork must be fabricated and
installed by the installing contractor before the unit is set
into place.
Note:
For sound considerations, cut only the holes in the
roof deck for the ductwork penetrations. Do not cut
out the entire roof deck within the curb perimeter.
Trane's Engineering Bulletin RT-PRB022-EN provides
additional information concerning duct design and sound
reduction.
