Installation
The GHE80SS/SU and GHE100SS/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 polypropylene
pipe and fittings listed in the tables below are ULC-S636 listed.
*Can also be BL instead of L. A lock ring should be used at every pipe/tting connection.
**Connector rings should be used for all pipe/tting connections.

TERMINALS
The GHE80SS/SU and 100SS/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.
