How to Light the Pilot on a Water Heater

The water heater is what heats the water in the home. When you notice the water is not hot anymore, it is usually because the pilot light has gone out. The most common cause of the pilot light going out is drafts that enter the area where the pilot light is located. Lighting the pilot is easy to do after you learn how to do it properly and safely.

1. Turn the heat to the low temperature on the water heater. There should be a temperature knob on the exterior of the unit for the temperature.


2. Look for the metal access panel, which should be under the temperature knobs. Remove any screws, if necessary.


3. Use a flashlight to locate the knob that controls the gas. Turn the knob to the “off” position. Wait three minutes to allow the gas to clear the pipes. Gently blow through the access door to remove any remaining gas vapors.


4. Light a match. Turn the gas control knob and hold the match over the opening of the metal pilot light tube.


5. Press and hold the reset button on the gas control knob until the pilot light is lit. Continue to hold the button for one minute after the pilot light is lit.


6. Turn the gas control knob to the “on” position.


7. Replace the metal access panel and screws.


8. Turn the temperature knob to the temperature you desire. The most common temperature setting for the home is 120 degrees.
