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 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 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.
