Rheem GHE80SU Use & Care Manual page 27

The GHE80SS/SU, GHE100SS/SU, and GHE119SS/SU models have been certified to use polypropylene pipe for both the
intake and exhaust vent systems, but must use the current PVC vent terminations (including concentric vents). All poly-
propylene pipe and fittings listed in the tables below are ULC-S636 listed.

*Can also be BC instead of C. A lock ring should be used at every pipe/fitting connection.
**Connector rings should be used for all pipe/fitting connections.
The GHE80SS/SU, GHE100SS/SU, and GHE119SS/SU models can be vented using rigid polypropylene pipe, to the
same vent lengths called out in the current GHE manuals (AP14729-5 and AP18494). The overall vent length (pipe and
elbows) must fall within the allowable vent terminal configurations shown in the manuals. An adapter (see charts above)
will be needed to join the polypropylene pipe to the PVC pipe shipped with the units.
At the vent terminations, the polypropylene pipe will need to convert back to one of the allowable PVC termination
configurations currently used.
Page 28 shows what a complete vent set up would consist of for either the intake or exhaust vent system.
