How to Light a Pilot Gas Water Heater

Gas water heaters are a popular choice for many homeowners due to their efficiency, reliability, and cost-effectiveness. However, when the pilot light goes out, it can be frustrating and challenging to relight it. In this article, we will provide a step-by-step guide on how to light a pilot gas water heater.

Understanding the Pilot Light

Before we dive into the steps, it’s essential to understand what the pilot light is and its purpose. The pilot light is a small flame that ignites the main burner, which in turn heats the water in the tank. The pilot light is usually located at the bottom of the water heater and is connected to a thermocouple, which helps to regulate the temperature.

Step-by-Step Instructions to Light the Pilot

1. Turn off the gas supply: Before attempting to relight the pilot, turn off the gas supply to the water heater by locating the shut-off valve and turning it clockwise. This will prevent any accidental ignition of the pilot light.
2. Open the access panel: Locate the access panel on the front of the water heater and remove it. This will give you access to the pilot light and burner assembly.
3. Locate the pilot light: Look for the pilot light orifice, which is usually a small hole at the bottom of the water heater. This is where the pilot flame will emerge.
4. Turn the pilot knob: Locate the pilot knob, which is usually located on the side of the water heater. Turn the knob counterclockwise until it stops. This will allow gas to flow to the pilot light.
5. Light the pilot: Use a lighter or matches to light the pilot light. Hold the flame to the pilot orifice for about 10-15 seconds, or until the pilot light is burning steadily.
6. Adjust the pilot flame: Once the pilot light is lit, adjust the flame to the recommended height. This is usually specified in the user manual or on the side of the water heater.
7. Turn the pilot knob back: Once the pilot light is adjusted, turn the pilot knob clockwise until it stops. This will stop the flow of gas to the pilot light.
8. Check the thermocouple: Make sure the thermocouple is securely attached to the pilot light and is not blocked by any debris.

Tips and Tricks

• Use a lighter or matches: Avoid using a flashlight or other open flame, as this can create a fire hazard.
• Keep the area well-ventilated: Make sure the area around the water heater is well-ventilated to prevent the buildup of carbon monoxide.
• Check the gas supply: Before attempting to relight the pilot, make sure the gas supply is turned on.
• Check the user manual: Consult the user manual for specific instructions on how to light the pilot light on your particular water heater model.

Troubleshooting Common Issues

• Pilot light won’t stay lit: Check the thermocouple to make sure it’s securely attached and not blocked by any debris. Also, check the pilot knob to make sure it’s not loose.
• Pilot light is too small: Adjust the pilot knob counterclockwise to increase the flow of gas to the pilot light.
• Pilot light is too large: Adjust the pilot knob clockwise to decrease the flow of gas to the pilot light.

Safety Precautions

• Never touch the pilot light: The pilot light is extremely hot and can cause serious burns.
• Keep children and pets away: Make sure children and pets are kept away from the water heater while it’s in operation.
• Never use a blowtorch or other open flame: This can create a fire hazard and damage the water heater.

Conclusion

Lighting a pilot gas water heater may seem like a daunting task, but by following these simple steps, you can relight the pilot and get your water heater up and running again. Remember to always follow safety precautions and consult the user manual for specific instructions on how to light the pilot light on your particular water heater model.
