POLYPROPYLENE INSTALLATIONS
The water heater has been approved to be installed with
Polypropylene vent material as shown in Tables 7 and 8.
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 6 on Page 23 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.
Installations must comply with applicable national, state,
and local codes. For Canadian installation, Polypropylene
vent must be listed as a ULC-S636 approved system. If
Polypropylene vent is not required by your local code, you
may use either PVC or CPVC pipes for your water heater that
allows non-metallic venting material installations.
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 UL 1738 or 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
3” and 4” diameter pipes.
