Step 1: Prepare the Area
Before attempting to light the pilot light, make sure:
- Turn off the gas supply: Locate the gas shut-off valve and turn it clockwise to shut off the gas supply to the water heater.
- Ensure the area is well-ventilated: Open a window or turn on an exhaust fan to prevent the buildup of gas and carbon monoxide.
- Wear protective gear: Wear gloves and safety glasses to protect yourself from potential hazards.
Step 2: Identify the Pilot Light Assembly
Locate the pilot light assembly, which is usually a small metal tube with a knob or button. The assembly may be located at the bottom, side, or top of the water heater.
Step 3: Remove Any Obstructions
Remove any debris or sediment that may be blocking the pilot light assembly. Use a soft brush or cloth to clean the area.

Follow these steps to light the pilot light:
- Press the pilot light button: Press the pilot light button or knob to release the gas.
- Hold a lighter or match: Hold a lighter or match near the pilot light opening, making sure not to touch the flame to the pilot light assembly.
- Light the pilot light: Once the gas is released, ignite the pilot light with the flame. You should see a small, steady flame.
- Adjust the pilot light: Once lit, adjust the pilot light to ensure it’s centered and burning steadily.
Step 5: Check the Pilot Light
Verify the pilot light is:
- Lit: Check that the pilot light is burning steadily.
- Properly adjusted: Ensure the pilot light is centered and not leaning to one side.
- Not too high or too low: Adjust the pilot light if it’s too high or too low.
Common Issues and Troubleshooting
