8. If lock-out occurs before main burner lights, turn switch to “OFF”,
wait five seconds and turn switch to “ON” position. This will
restart the ignition cycle. The first start-up of the heater may

2. Turn off the electrical power to the appliance.
3. Turn off gas supply.

120 Volt AC Option
Electric water heaters are designed to operate with a minimum

To energize the electric heating element, turn the switch to “ON”.
The switch is located behind the water heater door in the lower left
corner of the control housing. The water temperature will be
regulated by the thermostat.
