How to Turn Pilot Light On Furnace?

Turning on the pilot light on your furnace is a crucial step to ensure your heating system is functioning properly. A pilot light is a small flame that ignites the main burner to provide heat to your home. In this article, we will guide you through the step-by-step process of turning on the pilot light on your furnace.

Before You Start

Before attempting to turn on the pilot light, make sure you have:

• A reliable gas supply
• A functional thermostat
• A properly installed furnace
• A clear understanding of the safety precautions involved

Step 1: Locate the Pilot Light Assembly

The pilot light assembly is usually located at the bottom of the furnace, near the gas valve. You may need to refer to your furnace’s user manual or look for a label on the furnace to find the exact location.

Step 2: Shut Off the Gas Supply

Important: Before attempting to turn on the pilot light, shut off the gas supply to the furnace. This is a critical safety precaution to prevent any accidental gas leaks or fires. You can usually find the gas shut-off valve near the furnace or on the gas line.

Step 3: Remove the Pilot Light Assembly

You will need to remove the pilot light assembly to access the pilot light. This may require a screwdriver or a wrench, depending on the type of assembly you have. Gently pull the assembly away from the furnace to access the pilot light.

Step 4: Clean the Pilot Light Assembly

Use a soft cloth or brush to clean the pilot light assembly and remove any debris or dust that may be obstructing the pilot light.

Step 5: Relight the Pilot Light

To relight the pilot light, follow these steps:

• Hold a lit match or lighter near the pilot light orifice (the small hole where the pilot light flame will appear).
• Turn the gas valve counterclockwise to allow gas to flow to the pilot light.
• Continue to hold the match or lighter near the orifice until the pilot light ignites.
• Once the pilot light is lit, turn the gas valve clockwise to shut off the gas supply.

Step 6: Adjust the Pilot Light

Use the adjustment screw or nut to adjust the pilot light flame to the recommended size. Refer to your furnace’s user manual for specific instructions on how to adjust the pilot light.

Step 7: Test the Pilot Light

Once the pilot light is lit and adjusted, test it by holding a lit match or lighter near the orifice. The pilot light should stay lit and not go out.

Troubleshooting Common Issues

• Pilot light won’t stay lit: Check the gas supply and ensure that it is turned on. Also, check the pilot light assembly for any blockages or debris.
• Pilot light is too high or too low: Adjust the pilot light assembly to ensure that the flame is at the correct height.
• Pilot light is not igniting: Check the gas valve and ensure that it is turned counterclockwise to allow gas to flow to the pilot light.

Safety Precautions

• Always shut off the gas supply to the furnace before attempting to turn on the pilot light.
• Use a lit match or lighter to relight the pilot light, as this is a safer option than using a flame from a lighter or match.
• Keep the pilot light assembly clean and free from debris to prevent any obstructions.
• Avoid touching any electrical components or wires near the pilot light assembly.

Conclusion

Turning on the pilot light on your furnace is a relatively simple process that requires some basic steps and safety precautions. By following the steps outlined in this article, you should be able to successfully turn on the pilot light and ensure that your heating system is functioning properly.
