Introduction: Gas heaters are a popular choice for providing warmth during the colder months. However, when the pilot light goes out, it can leave you in the cold. Knowing how to safely relight the pilot on a gas heater is essential to restore its functionality.
In this article, we will guide you through the step-by-step process of lighting the water heater pilot light on a gas heater, ensuring a warm and comfortable environment in your home.
Understanding the Pilot Light: The pilot light is a small, continuously burning flame that ignites the gas burner in a gas heater. It acts as the ignition source, responsible for heating the air that circulates throughout the heater. If the pilot light goes out, the heater will not function until it is successfully relit.

Step-by-Step Guide to Lighting the Pilot on a Gas Heater:
- Safety First: Before attempting to relight the pilot, ensure the gas valve on the heater is in the “off” position. Also, open nearby windows for ventilation, allowing any accumulated gas to dissipate.
- Locate the Pilot: Depending on the type of gas heater, the pilot can be found in different places. Look for a small access panel near the bottom of the heater. Open it to reveal the pilot assembly.
- Find the Controls: Inside the access panel, you will find the gas control knob or valve. Look for the “Off,” “Pilot,” and “On” positions. Set the control knob to the “Off” position and wait for a few minutes to allow any remaining gas to disperse.
- Prepare the Lighter: While waiting, make sure you have a long-reach lighter or fireplace match ready for ignition. These tools will help you light the pilot without risking your fingers.
- Set to Pilot: Once the waiting period is over, turn the gas control knob to the “Pilot” position. While holding the knob in this position, press the ignition button or lever (if available) to release gas to the pilot assembly.
- Ignite the Pilot: Use the long-reach lighter or match to ignite the gas at the pilot assembly. Carefully place the flame near the pilot burner while continuing to hold the gas control knob in the “Pilot” position. The pilot flame should ignite.
- Hold and Release: Keep holding the gas control knob in the “Pilot” position for about 30 seconds to allow the thermocouple to heat up. The thermocouple is a safety device that detects the presence of the pilot flame. Once the thermocouple is heated, release the gas control knob.
- Switch to “On”: Turn the gas control knob from the “Pilot” position to the “On” position. This will allow gas to flow to the main burner, which will now ignite and start heating your space.
Conclusion: Knowing how to safely light the pilot on a gas heater is a valuable skill that ensures you can restore warmth and comfort to your home. By following the step-by-step guide above, you can confidently relight the pilot and enjoy the benefits of a functional gas heater.
Remember to prioritize safety by following the recommended precautions, such as ensuring proper ventilation and using long-reach lighters or matches. Regularly inspecting and maintaining your gas heater will also contribute to its efficient and reliable performance. With these essential skills and knowledge, you can confidently tackle pilot light issues and keep your home cozy throughout the cold seasons.
