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 latest 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 gas control knob located on the thermostat must be turned to the “ON” position for the gas to be able to flow.

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

5.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
