Reliance Water Heaters 606 Operating, Before The Water Heater Will Operate, Operation, All Models

Operating

This water heater is equipped with an electrically operated venting system and electronic control. For the burner to come on, the water heater thermostat must call for heat. Then the system will begin sequencing, each section prov- ing itself before gas is allowed to flow to the burner.

BEFORE THE WATER HEATER WILL OPERATE:

1.The control system must be connected to a grounded 110/120 volt power supply. The control system has an overall rating of 2 amps. The water heater must be securely and adequately grounded in accordance with local codes and with the current edition of the National Electrical Code ANSI/NFPA 70.

2.The ON/OFF toggle switch, located on the control box above the thermostat must be in the “ON” position for the electrical control system to operate allowing the gas portion to operate (ignite burner).

3.The venting manual reset switch must be in the closed position. See “Venting Manual Reset Switch” in the “For Your Information” section.

4.There is a non-resettable hi-limit switch in the thermo- stat, which must be good (closed) for the thermostat to be operated. See “High Temperature Shut Off System” in the “For Your Information” section.

OPERATION

When the thermostat calls for heat, gas is allowed to flow to a (N/O) pressure switch closing it. An electrical circuit is then made to the blower, turning it on. When the blower has achieved sufficient venting, the air pressure switch will close. A 120 volt circuit will be completed through the venting manual reset switch and on to the 120 volt gas valve. The 120 volt gas valve will open allowing gas to flow to the burner. The hot surface ignitor will establish a main burner flame.
