8 Step-by-Step Guide on How to Light a Pilot Light on a Propane Furnace

Step 1: Locate the Pilot Light and Gas Valve

The first step in lighting the pilot light on your propane furnace is to locate both the pilot light and the gas valve. Typically, the pilot light can be found near the bottom of the furnace, often behind a small access panel. Ensure the area is well-lit with your flashlight to help you see clearly.

The gas valve, which controls the flow of propane to the pilot light, is usually situated adjacent to the pilot assembly. It may be labeled with instructions such as “On,” “Off,” or “Pilot.” Familiarizing yourself with these components is essential before proceeding to the next steps, as it sets the foundation for safely lighting the pilot light.

Step 2: Turn Off the Gas Supply

Once you have located the pilot light and gas valve, the next crucial step is to turn off the gas supply. This is an important safety precaution to prevent any gas from leaking while you work on relighting the pilot light. To do this, simply rotate the gas valve to the “Off” position. You may notice that the valve has a specific marking indicating “Off.”

Ensure that it is completely turned off before proceeding. Wait for a few minutes to allow any residual gas to disperse, which further enhances safety. Once you are confident that the gas is completely shut off, you can move on to the next step in the process.

Step 3: Remove the Access Panel

After ensuring that the gas supply is turned off and any residual gas has dispersed, the next step is to remove the access panel that covers the pilot light and the burner assembly.

Remove the Access Panel

This panel is typically secured with screws or clips, which may require a screwdriver or your fingers to detach. Carefully take off the panel and set it aside in a safe place to avoid losing any hardware.

Inspect the area for any signs of dirt or debris, as a clean surface will make lighting the pilot light easier. Once the access panel is removed, you will have a clear view of the pilot light and gas assembly, allowing you to proceed with the lighting process.

Step 4: Prepare the Pilot Light for Lighting

Before attempting to light the pilot light, it is essential to ensure that it is ready for ignition. Using a small brush or compressed air, gently clean any dust or debris around the pilot light and burner assembly. Additionally, check that the pilot light tube is free from any blockages or obstructions.

Once you have cleared the area and confirmed everything is in good condition, carefully move on to lighting the pilot light.

Step 5: Locate and Identify the Pilot Light Valve 

With the access panel removed and the pilot light area prepared, the next step is to locate and identify the pilot light valve. This valve is a critical component that regulates the flow of gas, specifically to the pilot light.

Look for a small valve typically situated near the pilot assembly, which may be integrated with or adjacent to the gas valve you encountered earlier. The pilot light valve may be labeled distinctly, often marked with “Pilot” or a similar term to signify its purpose.

It is important to ensure that you have accurate identification of this valve before proceeding, as it will allow for a safe and proper lighting process. Once located, ensure that the pilot light valve is set to the “Pilot” position, which is essential for allowing gas to flow to the pilot light when you attempt to ignite it.

Step 6: Light the Pilot Light

Now that everything is in place, it’s time to light the pilot light. Using your long-stemmed lighter or matches, carefully ignite the flame at the tip of the pilot light tube. Once lit, continue holding down on the reset button while keeping the flame steady for about 30 seconds. This allows enough time for gas to flow and reach the pilot light, establishing a steady flame.

If the pilot light does not stay lit after releasing the reset button, repeat this step until it remains continuously lit without assistance.

Step 7: Bring Back the Access Panel and Turn On the Gas Supply

Once your pilot light is successfully ignited and remains lit without assistance, you can now bring back the access panel and secure it in place. Return any screws or clips, making sure they are tightly fastened to ensure safe operation.

With the access panel secured, it is time to turn the gas supply back on. Simply rotate the gas valve to the “On” position and wait for a few minutes before proceeding. This allows enough time for gas pressure to build up, ensuring that everything is functioning correctly before turning on your furnace.

Step 8: Test Your Furnace

After following all previous steps successfully and safely lighting your pilot light, it’s time to test your furnace. Turn on your thermostat and set it to a higher temperature than the current room temperature. If everything is working correctly, your furnace should turn on, and warm air should start blowing through your vents.

However, if you encounter any issues with your furnace not turning on or producing heat, it may be a sign of a more significant problem that requires professional assistance. In this case, consult a licensed technician for further diagnosis and repair.

Following these steps on how to light a pilot light on a propane furnace properly will ensure safe and efficient lighting of your pilot light on a propane furnace. Remember to always prioritize safety by wearing protective gear and following all manufacturer’s guidelines for maintenance and operation.

Test Your Furnace

Regularly inspecting and maintaining your furnace can also prevent future issues and extend its lifespan, saving you time and money in the long run.
