POLYPROPYLENE INSTALLATIONS
The water heater has been approved to be installed with
Polypropylene vent material as shown in Table 5 and Table 6. The
approved application of single wall, non-flexible, non-concentric
Polypropylene vent material is offered by two specific manufacturers
(Centrotherm ECO Systems and DuraVent Polypropylene. These
listed products must be installed by following the vent manufacturer’s
instructions. Refer to “Table 7” on Page 26 to determine the maximum
pipe length and number of elbows that can be used.
Insulation should not be used on Polypropylene venting materials.
The use of insulation will cause increased vent wall temperatures,
which could result in vent pipe failure.
Use only the adapters and vent system listed in Tables below. DO
NOT mix vent systems of different types or manufacturers. Failure
to comply could result in severe personal injury, death, or substantial
property damage.

Polypropylene vent systems do not use cement to connect the pipe
and elbow sections but use a push together gasket seal method.
Do not attempt to connect Polypropylene with sealant cement. All
vent connections MUST be secured by the vent manufacturer’s joint
connector. The installer must use a specific vent starter adapter at
the flue connection. The adapter is supplied by the vent manufacturer
to adapt to its vent system.
In order to be in full compliance with ULC-S636 and to meet the
requirements of the water heater manufacturer, you must use the
metal joint connector rings, available from the Polypropylene vent
manufacturer, to stiffen the joints of 2”, and 3” diameter pipes.
