How to Light an Old Furnace Pilot: A Step-by-Step Guide
Lighting an old furnace pilot can be a challenging task, but with the right guidance, you can do it successfully. In this article, we will provide a step-by-step guide on how to light an old furnace pilot, highlighting the most important points and providing tips and tricks to make the process easier.
Why is it Important to Light the Pilot Light?
Before we dive into the steps, it’s essential to understand why lighting the pilot light is crucial. The pilot light is responsible for igniting the main burner, which provides heat to your home. Without a properly lit pilot light, your furnace won’t be able to function, leaving you without heat during the cold winter months.
Preparation is Key
Before attempting to light the pilot light, make sure you have the following:
- A working flashlight (in case the pilot light is in a dark location)
- A screwdriver or wrench (depending on the type of pilot light valve)
- A matches or lighter
- A spare pilot light orifice (in case the existing one is clogged)
Step 1: Turn Off the Gas Supply
Important: Before attempting to light the pilot light, make sure the gas supply is turned off. This can be done by locating the shut-off valve and turning it clockwise. Verify that the valve is fully closed to ensure your safety.
Step 2: Remove the Pilot Light Assembly
Caution: Be careful when handling the pilot light assembly, as it may be hot. Use a wrench or screwdriver to remove the pilot light assembly from the furnace. Do not touch any electrical components.
Step 3: Clean the Pilot Light Orifice
Use a small brush or toothbrush to clean the pilot light orifice. Remove any debris or sediment that may be clogging the orifice.
Step 4: Light the Pilot Light
Hold the matches or lighter near the pilot light orifice and gently blow on the orifice to help the flame ignite. Keep the flame small and steady to ensure it doesn’t go out.
Step 5: Adjust the Pilot Light
Once the pilot light is lit, adjust the pilot light to the correct height. This is usually marked on the pilot light assembly. Make sure the pilot light is not too high or too low, as this can affect the furnace’s performance.
Step 6: Turn On the Gas Supply
Important: Once the pilot light is adjusted, turn on the gas supply by turning the shut-off valve counterclockwise. Verify that the valve is fully open to ensure the furnace is receiving the correct amount of gas.
Troubleshooting Tips
- If the pilot light doesn’t ignite, check the pilot light orifice for clogs and clean it accordingly.
- If the pilot light keeps going out, check the pilot light assembly for proper alignment and adjust it if necessary.
- If the furnace is not producing heat, check the thermostat setting and ensure it’s set to "heat" mode.
Safety Precautions
- Always turn off the gas supply before attempting to light the pilot light.
- Never touch any electrical components while working on the furnace.
- Make sure the area is well-ventilated to avoid inhaling any fumes.
- If you’re not comfortable with the process, consider hiring a professional HVAC technician.
Conclusion
Lighting an old furnace pilot may seem daunting, but by following these steps and taking the necessary precautions, you can do it successfully. Remember to always prioritize safety and follow the manufacturer’s instructions. If you’re unsure or uncomfortable with the process, it’s always best to consult a professional HVAC technician.
