Assembly and Installation
The following procedure explains how to assemble and
install roof curbs provided by Trane. An attachment
specific to your roof curb is shipped with your Trane-
ordered roof curb. See typical exploded view and parts list
in Figure 22, p. 15 and Tabl e 4, p. 16. In order to properly
locate the duct supports (if required) and external piping
cabinet (if ordered), it is recommended that you have a
copy of the as-built curb drawings from the submittal
package. For specialty or field-fabricated roof curbs please
see the section entitled “Specialty Roof Curbs,” p. 12 for
important information.

WARNING
Risk of Roof Collapsing!
Failure to ensure proper structural roof support could
cause the roof to collapse, which could result in death
or serious injury and property damage. Confirm with a
structural engineer that the roof structure is strong
enough to support the combined weight of the roof
curb and the unit. Refer to “Dimensions and Weights,”
p. 7 for typical curb weights.
