Vent Pipe Material

This heater is certifi ed to be installed using Schedule 40
PVC or CPVC or polypropylene plastic vent material for
the exhaust. All jurisdictions in Canada require that the
material used to exhaust combustion products is approved
to ULC S636. The combustion air intake material may be
PVC, ABS, CPVC or polypropylene. Check local codes
to determine which materials are allowed in your area
and only use approved material. All venting material and
components must be joined with the approved primer/
cleaner and solvent cement. Do not cement the venting
system to the heater.
Note: Plastic pipe and fi ttings are available through most
plumbing suppliers. Always check the marking on the pipe
to make sure you are using the correct material.

Vent Pipe Installation

The following guidelines should be followed when installing
the air intake and exhaust vent system:
•
•
•
•
•
The combustion air intake and exhaust vent system and
termination may be installed in one of the following type
terminations:
1. Horizontal (2 Pipe) (air intake and exhaust vent)
2. Vertical (2 Pipe) (air intake and exhaust vent)
3. Concentric Vent Termination (horizontal/side wall
4. Concentric Vent Termination (vertical/roof installation).
This water heater has been design certified by CSA
International for use with the specifi ed (CSA) listed plastic
vent pipe.
Do not use solvent cement to connect the exhaust vent
system to the blower. Use the rubber coupling and gear
clamps instead. This connection must be removable to
service the heater. All other joints in the air intake and
exhaust vent systems must be properly cemented.

Venting should be as direct as possible with a minimum
number of pipe fi ttings.
Vent diameter must not be reduced unless specifi cally
noted in the installation instructions.
Support all horizontal pipe runs every 1.2m (4') and all
vertical pipe runs every 1.52m (5') or according to local
codes or venting manufacturer's instructions.
Vents run through unconditioned spaces where
below freezing temperatures are expected, are not
recommended.
Vents run through unconditioned spaces inside a
building may result in the condensation of fl ue gases
during the winter season. The rubber coupling joined to
the blower includes a nipple with a cap. In installations
such as this connect a condensation trap to this nipple.

• Primers and cements are
extremely flammable, and must
not be stored or used near heat
or open flame.
• Also, use only in a well venti-
lated area.
• Cans of cement and primer should
be closed at all times when not in
use to prevent evaporation of
chemicals and hardening of cement.
• They are also very flammable and
should be kept away from heat or
flame.
