Installation Manual

27
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 specic vent starter
adapter at the ue 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 4” and 6” diameter pipes.
POLYPROPYLENE INSTALLATIONS
The water heaters covered by this manual have been approved to be
installed with Polypropylene vent material as shown in Table 8 and Table
9. The approved application of single wall, non-exible, non-concentric
Polypropylene vent material is offered by two specic 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 22 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.

AL29-4C® VENT INSTALLATIONS
(AL29-4C® is a registered trademark of Allegheny Technologies, Inc.)
The water heaters covered by this manual are approved to be installed with AL29-4C® stainless steel vent material using parts
from the manufacturers listed in Table 10 and Table 11 below. These listed systems must be installed using the vent manufacturer’s
instructions including their listed clearances to combustible and noncombustible materials. Refer to Table 7 on page 22 for the
maximum and minimum equivalent linear vent lengths and number of elbows that may be used. However, use Table 10 and Table 11
below to nd the appropriate equivalent linear vent lengths for the AL29-4C® elbows.
Note: The equivalent lengths of the AL29-4C® elbows are different than those from smooth walled plastic vents. Consult Table 10
and Table 11 for the correct equivalent linear vent lengths.
Listed vent systems composed of AL29-4C® must not mix parts from the different manufacturers. The joints of these products are
sealed by internal gaskets. Do not use any other type of sealant. When assembling these vent systems, follow the vent manufacturer’s
instructions for cleaning and lubricating the joints, if required. Each section must be locked together using the method supplied by
the vent manufacturer.
The water heaters covered by this manual are approved to be installed using the approved vent terminations shown in this manual.
This means that, the installer must use the adapter listed in Table 10 and Table 11 and a short piece of PVC pipe to complete the end
of the vent system with an approved termination. In Canada, the PVC pipe length must be listed to ULC636.
