How to Lite a Pilot Light on a Furnace?
Having a properly functioning pilot light on your furnace is essential for safe and efficient heating. A pilot light is a small flame that ignites the main burner in your furnace, allowing it to produce heat. In this article, we will guide you through the process of lighting a pilot light on a furnace.
Why is it Important to Have a Properly Lit Pilot Light?
- A properly lit pilot light ensures that your furnace functions safely and efficiently.
- A faulty pilot light can cause the furnace to produce carbon monoxide, a deadly gas.
- Ignoring a faulty pilot light can lead to a loss of heat during the cold winter months.
Preparing to Light the Pilot Light
Before attempting to light the pilot light, ensure that you have:
- Turned off the power to the furnace: Switch off the electrical power to the furnace at the circuit breaker or fuse box.
- Set the thermostat to "Off": Ensure that the thermostat is set to "Off" to prevent the furnace from turning on during the lighting process.
- Removed any tripped or faulty circuit breakers: Check the circuit breaker panel for any tripped or faulty breakers and replace them if necessary.
- Checked the pilot light assembly: Make sure the pilot light assembly is free from debris and obstructions.
Lighting the Pilot Light
- Locate the Pilot Light Assembly: The pilot light assembly is usually located at the bottom of the furnace or on the side. It may be marked with a label indicating that it is the pilot light assembly.
- Remove the Pilot Light Shield: Gently pull away the pilot light shield or cover to access the pilot light.
- Turn the Pilot Light Valve: Locate the pilot light valve, usually marked "Pilot" or "Ignite". Turn it clockwise until it stops, then counterclockwise until it clicks. This will allow gas to flow to the pilot light.
- Press and Hold the Ignition Button: Press and hold the ignition button for approximately 30 seconds. This will allow the gas to flow to the pilot light and ignite the flame.
- Release the Ignition Button: Once the pilot light is lit, release the ignition button. The pilot light should continue to burn.
- Adjust the Pilot Light: Use the pilot light adjustment screw or screwdriver to adjust the flame height to the recommended level.
Troubleshooting Common Issues
- Pilot Light Won’t Stay Lit: Check for drafts, air leaks, or faulty thermocouples that may be extinguishing the pilot light.
- Pilot Light Fails to Ignite: Check the pilot light valve and ensure it is fully opened. Also, check for blockages or debris in the pilot light assembly.
Safety Precautions
- Be Careful with Open Flames: When lighting the pilot light, be careful not to touch any open flames with your bare skin.
- Keep the Area Clear: Ensure the area around the furnace is clear of any flammable materials.
- Wear Protective Gear: Wear safety goggles and gloves when working around the furnace to prevent accidental injuries.
Conclusion
Lighting a pilot light on a furnace may seem daunting, but by following the steps outlined in this article, you can do it safely and efficiently. Remember to turn off the power to the furnace, set the thermostat to "Off", and check for any tripped or faulty circuit breakers before attempting to light the pilot light. If you encounter any issues, refer to the troubleshooting section for guidance.
Additional Tips and Recommendations
- Regularly Inspect the Pilot Light: Regularly inspect the pilot light for any signs of wear or damage. Replace the pilot light assembly if necessary.
- Replace the Pilot Light Assembly Every 5-10 Years: It is recommended to replace the pilot light assembly every 5-10 years to ensure optimal furnace performance and safety.
- Consult a Professional If Necessary: If you are unsure or uncomfortable with any part of the process, consult a professional HVAC technician for assistance.
By following these steps and guidelines, you can ensure your pilot light is properly lit, and your furnace functions safely and efficiently.
