Light a water heater by waiting for gas to dissipate, turning the control knob to pilot, igniting the flame, holding the control knob pressed in for one minute and turning the knob to the on position. Never attempt to light a gas appliance if you smell gas in the area.Continue Reading
Move the gas switch to the off position. Wait at least five minutes after turning the unit off before attempting to light the heater.
The unit has a safety valve that prevents gas from flowing until the thermocouple is hot. Press the control knob in toward the tank or press the red bypass button on the module when you are ready to light the flame.
Unless your water heater has a piezoelectric starter, you need a long barbecue lighter to ignite the flame. Once the bypass valve is pressed, quickly move the lighter through the port to light the pilot or press the start button.
Continue holding the knob or button in position for a full minute to allow the pilot to heat the thermocouple. If you release the knob before it is hot, the unit extinguishes the flame.
Release the knob, and turn it to the on position. If the water in the tank is below temperature, the larger burner lights immediately when you turn the knob.
