ventingsystem.
WARNING
The venting system must be properly installed. Failure to properly install the vent system could result in
property
damage, personal injury, or death.
DO NOT install damaged venting system components. If damage is evident then please contact the supplier
where
the water heater or venting system components were purchased for replacement parts.
Use only the vent terminals provided or factory authorized terminals for venting this water heater.
The water heater requires its own separate venting system. Do not connect the exhaust vent into an existing vent
pipe
or chimney.
All of the exhaust venting connections must be leak checked with a soap solution upon initial start-up of the
water
heater. Any leaks must be repaired before continuing operation of the water heater.
Do not terminate the venting where noise from the exhaust or intake will be objectionable. This includes
locations
close to or across from windows and doors. Avoid anchoring the vent and intake pipes directly to framed
walls, floors,
or ceilings unless rubber isolation pipe hangers are used. This prevents any vibrations from being
transmitted into the
living spaces.
Do not exceed the venting distances or the number of elbows listed in the instruction manual supplied with the
water
heater. Exceeding the maximum venting distances may cause the water heater to malfunction or cause
an unsafe
condition.
DO NOT operate this water heater until the venting installation is complete and the piping completed. Failure
to
complete installation before operation can result in property damage, personal injury, or death.

WARNING
DO NOT install Duravent Polypro venting components with any other manufacturer’s vent components.
Duravent
components must be used exclusively throughout the entire venting system from the water heater
coupling or vent
connection to the outside wall or ceiling near the vent terminal location.
This supplement is intended only for additional information for installing Duravent Polypro single wall venting system
and the instruction manual supplied with the water heater must be followed for the detailed information provided for
the
venting system installation.

WARNING
Use only water for lubricating the gaskets and pipe ends to allow easy insertion. DO NOT use any other kind of
lubricant, since deterioration of the gasket may result, which may allow dangerous flue gases to leak into the room.
If the vent pipe needs to be disassembled after the gasket has dried, wet the joint thoroughly to loosen the
connection.
