7.8 Exhaust Gas Outlet Pipe Materials
SAFETY
INSTRUCTIONS
For Canadian installations, plastic exhaust gas outlet
piping must comply with CAN/CGA B149.1 and be
certified to the Standard For Type BH Gas Venting
Systems, ULC-S636. Components of this listed system
must not be interchanged with other vent systems
or unlisted pipes or fittings. All plastic components
and specified primers and glues must be from a single
system manufacturer and must not be intermixed with
another system manufacturer’s products.
All units come factory installed with 4 inch polypropylene
(PP) venting. A polypropylene to PVC adapter is included
with each unit to enable the use of PVC exhaust gas outlet
pipe. The maximum allowable venting distances are the
same regardless of vent material selected.
The materials listed in the tables below outline the acceptable
exhaust gas outlet pipe materials:

*Note: Use of cellular core PVC (ASTM F891), cellular core CPVC, or Radel
(polyphenylsulfone) in nonmetallic venting systems is prohibited. Covering
non-metallic vent pipe and fittings with thermal insulation is prohibited.
**Note: The components (pipe, fittings, primers, and glues) must
be from a single manufacturer; do not interchange. Follow the vent
manufacturer’s certified instructions.
SAFETY
INSTRUCTIONS
Do not use cellular foam core pipe to vent exhaust
gases.
This water heater has a built-in exhaust gas outlet temperature
control that limits the exhaust gas temperature to a maximum
of 149°F (65°C) for PVC pipe. In commercial applications
which require higher water temperatures, exhaust gas
temperature can reach 190°F (88°C) and require materials
such as polypropylene (PP), stainless steel (SS), or CPVC.
If the temperature approaches the upper limit, the burner
will turn off automatically to protect the vent pipe. Once the
exhaust gas temperature has dropped to a normal operating
level, the unit will automatically restart.
If the inlet/return water temperature will exceed 150°F
(66°C), do not use PVC pipe. Follow the display prompts
to set the maximum water temperature for the exhaust gas
outlet pipe material being used.
7.9 Air Intake Inlet Pipe Vent Materials
The air intake inlet pipe can be of any plastic or metal vent
material available. ABS, PVC, polypropylene, galvanized steel,
and/or flexible corrugated ducting are all examples. When
using a corrugated material, ensure there is no inadvertent
crimping or blockage to the air intake inlet pipe.
Refer to the table below for a list of approved materials.

Note: In addition to these charts, it is recommended to
consult the most recent edition of ANSI Z223.1/NFPA 54 or
CAN/CGA B149.1, as well as all applicable local codes and
regulations when selecting vent pipe materials.
