Venting
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
When installing the venting system, make sure to
follow all local codes or, in the absence of local
codes, CSA B149.1, Natural Gas and Propane Gas
Installation Code, in Canada, and/or the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, in the United
States. Never operate the water heater unless it is
properly ventilated to the outdoors and has adequate
air supply for proper operation. Failure to properly
install the venting system could result in property
damage, personal injury, or death.
According to the CSA B149.1, Natural Gas and
PropaneGasInstallationCode, plasticventingsystems
installed in Canada must be certified ‘‘STANDARD
FOR TYPE BH GAS VENTING SYSTEMS ULC
S636’’. Components of the certified venting system
must not beinterchangedwith otherventingsystems or
unlisted pipe/fittings. Plastic components and specified
primers and glues of the certified venting system must
be from a single venting system manufacturer and not
intermixed with other venting system manufacturer’s
venting system parts unless those are certified to
be used with this system. Plastic venting systems
shall also be installed such that the first three (3) feet
(91 cm) of pipe from the water heater outlet are readily
accessible for visual inspection.
IMPORTANT
The water might be vented using one of the following
options only:
• Three (3) inch (7.6 cm) or four (4) inch (10.2 cm)
schedule 40 PVC or CPVC, pipe and fittings.
•
Three (3) inch (7.6 cm) or four (4) inch (10.2 cm)
CentrothermTM polypropylene rigid pipe and fittings.
(InnoFlue®single-wallventsystem).

• Three (3) inch (7.6 cm) or four (4) inch (10.2 cm)
DuraVent®polypropylene rigid pipe and
fittings. (PolyPro®single-wall gas vent system).

Before installing the vent piping, make sure that the
venting system layout has been properly planned.
Verify that the location of the water heater respects
all clearances from combustible material, all venting
requirements (see Table 1), and that the vent terminal
will be installed as specified by all local codes or, in
the absence of local codes, CSA B149.1, Natural Gas
and Propane Installation Code, in Canada, and/or the
National Fuel Gas Code, ANSI Z223.1/NFPA 54, in
the United States (see Figure 11).
This water heater is equipped with a power venter that
evacuates the products of combustion to the outdoors.
All models are shipped from the factory with the power
venter already installed. This water heater must be
vented directly to the outdoors, either horizontally
through the wall or vertically through the roof. The
venting must not be attached to an existing chimney,
or in common with any other appliance, and must not
be insulated.

PVC or CPVC PIPES:
The PVC or CPVC pipe must be inserted directly into
the rubber transition fitting on the blower assembly
outlet (see Figure 9).
CENTROTHERM™ POLYPROPYLENE PIPE
