This water heater incorporates a combustion shut off device that shuts the operation of the water heater
down if undesirable combustion conditions occur, such as the presence of flammable vapors or blockage of
the combustion air inlet openings. Please contact a Qualified Service Technician if this occurs.
CAUTION: For your safety DO NOT attempt repair of gas piping, gas control (thermostat), burners, vent connectors,
dampers, or other safety devices. Refer repairs to qualified service personnel.
Problem Possible Causes What To Do
Condensation
This usually happens when a
new heater is lled for the rst
time
 This is normal. After the water in the tank warms up, the
condensation will disappear. If, however, the condition
persists, examine the piping and ttings for possible leaks.
Refer to the "Condensation" information in the "Installing
the Water Heater" section of this manual.
