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 vapours 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 or
other safety devices. Refer repairs to qualified service personnel.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. VERIFY PROPER OPERATION AFTER SERVICING.
