CARBON MONOXIDE POISONING
• Failure to properly seal the vent system could
cause flue products to enter the living space.
• (For flexible pipe for chimney)
Handle the flexible vent carefully.
Dropping, Crushing and Stacking may cause
damage, and may result in fires, property
damage or exposure to Carbon Monoxide.
WARNING
For flexible pipe for chimney
• During the installation, ambient temperatures
must be greater than 40 °F (5 °C). Afterwards,
installation site ambient temperature must
be greater than -4 °F (-20 °C). Flexible vent
pipe breakage may occur if these temperature
requirements are not observed.
• Only listed manufacture specified vent parts
may be used for this appliance. Refer to the
manufacture’s literature for detailed information.
NOTE
Covering non-metallic vent pipe and
fittings with thermal insulation is
prohibited.
For 2 in. flexible PP material
• Flex Vent 2 in. Conversion Kit (EZ2-CK) must
be used when using 2 in. flexible PP pipe for
vent pipe installation. Refer to the instructions
provided with Flex Vent 2 in. Conversion Kit for
additional detail.
• During the installation of Flex Vent 2 in. Kit
(EZ2FVK-1 and EZ2FVK-2), ambient temperatures
must be greater than 40°F (5°C). Afterwards,
installation site ambient temperature must be
greater than -4°F (-20°C). Flex vent pipe breakage
may occur if these temperature requirements are
not observed.
• Only listed manufacturer specified vent parts may
be used for this Water Heater.

• The Btu/h input of the Water Heater will be
reduced by up to 9% when maximum vent length.
• Use only solid PVC / CPVC (schedule 40) or PP
pipe.
• 2 in. or 3 in. schedule 80 pipe may also be used
on this Water Heater, however the Btu/h input of
the Water Heater will be reduced by up to 9%.
• Maintain the same vent pipe diameter from the
Water Heater flue to the termination.
• In Canada, plastic vent systems must be certified
to ULC S636. The components of the certified
vent system must not be interchanged with other
vent systems or unlisted pipe/fittings.
• In Canada, specified primers and glues of the ULC
S636 certified vent system must be from a single
system manufacturer and not intermixed with
other system manufacturer’s vent system parts.
