Electronic Control Display (Upper Control)

The Electronic Control Display panel used on this water heater provides an easy-to-read, eye level display for temperature adjustment, fault code diagnostics and recall, powered anode rod operation and setting the temperature scale for either Fahrenheit (°F) or Celsius (°C).

Gas Control Valve/Thermostat (Lower Control)

The gas control valve/thermostat is where the incoming gas supply is connected to the water heater. It is used in conjunction with the electronic control display to start or stop main burner operation. There is an On/Off switch located on the right-hand side of the control. The gas control valve/thermostat is energized by a 24 VAC power supply transformer and uses a temperature sensing probe to open or close the flow of gas to the main burner. The gas control valve has an inlet filter built into its body to prevent impurities in the gas system from contaminating the internal valves and a LED diagnostic light located in the lower right hand corner of the valve to display any micro-computer fault experienced by the control. On the bottom of the control is where electrical connections to the other component parts are attached along with the gas supply (manifold tube) to the main burner. The gas control/valve thermostat of this water heater is suitable for use on Natural gas only.
