SECTION VI: VENTING
WARNING
The vent 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 was purchased, or the manufacturer listed on the rating plate 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 startup 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 this manual. 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
Risk of carbon monoxide poisoning or fire due to joint separation or pipe breakage.
This water heater must be properly vented and connected to an approved vent system in good condition.
DO NOT
operate water heater with the absence of an approved vent system. A clean and unobstructed vent system is
necessary to allow noxious fumes that could cause injury or loss of life to vent safely and will contribute toward
maintaining the water heater’s efficiency. The acceptance of the venting system is dependent upon full compliance with
these installation instructions.
Venting system
must not
pass through rated fire separations.
The venting system must be free to expand and contract. This venting system
must be
supported in accordance with
these instructions.
