How to Relight a Gas Water Heater: Two Methods for Different
Method 1: Relighting a Water Heater with a Built-in Ignition Switch
1. This type of heater has an ignition button on the gas control valve, making relighting easier.
2. Turn Off the Gas. Locate the gas control knob (usually labeled "OFF," "PILOT," and "ON"). Turn it to the OFF position and wait 5 minutes to clear any lingering gas.
3. Remove the Metal Cover. Some models have a metal covering over the viewing window where you can see the pilot light. Remove this cover to gain visual access—do not open the entire access panel.
4. Set to Pilot Mode. Turn the gas control knob to PILOT. Press and hold the pilot button to allow gas to flow.
5. Ignite the Pilot. While holding the pilot button, press the red ignition switch multiple times until the pilot flame ignites. You should see a small blue flame through the viewing window.
6. Hold the Button. Keep holding the pilot button for 30-60 seconds to ensure the flame stays lit until the status light blinks. If the flame goes out, repeat the process.
7. Turn Gas Back On. Release the pilot button and turn the gas control knob to ON. The main burner should ignite within a few seconds.
8. Replace the Metal Cover. Secure the cover and adjust the temperature setting to your preference.
Method 2: Relighting a Water Heater with Manual Ignition
1. This type requires a long lighter or match to ignite the pilot manually.
2. Turn Off the Gas. Locate the gas control knob and turn it to OFF. Wait 5 minutes to clear any gas buildup.
3. Remove the Metal Access Panel. Some models require a Torx wrench to remove the metal access panel door. When removing the panel, check the gasket—if it’s worn out or damaged, replace it to prevent gas leaks.
4. Locate the Pilot Assembly. Inside, you’ll see the pilot assembly, which includes the pilot light, thermocouple, and burner.
5. Set to Pilot Mode. Turn the gas control knob to PILOT. Press and hold the pilot button to release gas.
6. Manually Light the Pilot. Use a long lighter or match to ignite the pilot light near the burner. You should see a small blue flame.
7. Hold the Button. Keep holding the pilot button for 30-60 seconds to ensure the flame stays lit. If the flame goes out, repeat the process.
8. Turn Gas Back On. Release the pilot button and turn the gas control knob to ON. The main burner should ignite.
9. Reattach the Access Panel. Secure the metal access panel using the Torx wrench, ensuring the gasket is intact. Adjust the temperature setting to your preference.
