How To Light Furnace Pilot

Do you ever get the feeling that you’re in the dark when it comes to furnace maintenance? Stuck with no idea of how to light a furnace pilot? Don’t worry – it just takes a little bit of knowledge and the right tools to get it done. Stay tuned to find out how to light a furnace pilot successfully!

Before you light or relight your furnace pilot, it’s important to understand how the system works. The pilot light is a small open flame that burns continuously to provide energy to the main burners, which keep the furnace functioning properly. Typically, it is lit manually using a match or lighter.

Safety Precautions for Lighting Your Pilot Light

  • Turn off the gas supply at the service panel.
  • Turn off the pilot light knob and wait at least five minutes for the gas to dissipate before attempting to light the pilot.
  • Wear protective clothing and avoid breathing in fumes.
  • Only use a match or lighter when necessary.

Steps for Successfully Lighting Your Pilot Light

  • Open the service panel and turn off the gas supply.
  • Turn the pilot light knob off and wait at least five minutes. Make sure to keep the area ventilated.
  • Hold a lit match or lighter near the pilot light opening and press the gas control knob for about one minute.
  • You should see a small flame and hear a slight hissing sound. Continue to press the knob until the flame stays lit.
  • Release the knob and wait a few minutes to ensure that the pilot light stays lit. If the pilot light wobbles or goes out, repeat the steps.

Troubleshooting Pilot Light Problems

If the pilot light won’t light or remain lit, you may need to check the thermocouple. The thermocouple is an electrical device that senses heat and usually shuts off the pilot light if it doesn’t detect enough heat. You may need to clean or replace the thermocouple to restore proper functioning. If the problem persists, it’s best to consult a qualified technician.

The Benefits of a Properly Lit Pilot Light

Ensuring your pilot light is lit properly can help to keep your furnace running efficiently and reduce the chances of a breakdown. A correctly functioning pilot light is essential to other components of your furnace such as the burners, as it provides heat to ignite the fuel. Additionally, a pilot light can provide peace of mind knowing that you and your family are safe and warm during cold winters.

Frequently Asked Questions

Q: What is the first step in lighting the furnace pilot?

A: Before starting any steps, make sure you have shut off the gas supply to the furnace. Then locate the gas ****, which is the valve that controls the flow of gas to the pilot and main burner. It should be located near the gas control valve or regulator.

Q: How do I adjust the gas ****?

A: Turn the knob or handle to the “off” position until it stops. Do not force the knob to turn. Once in the off position the knob should remain stationary.

Q: What should I do next?

A: Look for a small match stick-sized red button located near the gas ****. This is the pilot reset button and it will need to be pressed, holding it down for approximate 10-20 seconds. This will allow the gas to flow to the pilot.

Q: How do I light the pilot itself?

A: You’ll need to use a long-reach lighter like a fireplace lighter or a long match. Starting from the pilot valve, slowly hold the lighter over the pilot outlet. When the gas comes out of the pilot outlet, press the pilot reset button again. This will ignite the pilot flame and the pilot should stay lit.

In Conclusion

We hope that these steps have shown you how to light a furnace pilot quickly and easily. Remember, you should always follow the manufacturer’s instructions when dealing with gas-powered equipment and to contact a professional if something is not working as expected. Taking the time to properly maintain and care for your furnace will extend its useful life and save you money in the long run.
Lighting a furnace pilot is not something most homeowners do on a regular basis, but if your current furnace is not working, or you are replacing an old unit, you will need to be able to successfully light your furnace’s pilot.

Before beginning the actual pilot lighting process, take a few safety precautions. Make sure the furnace and the area near it is free of any debris and obstruction. Also, turn off the gas supply and remove the access panel on the furnace.

To start the pilot lighting process, locate the pilot light assembly. Following the manufacturer’s instructions carefully, locate the adjustable flame control knob. Most systems will require you to push it in and turn it counterclockwise. By moving the knob in this position, you will allow natural gas vapors to access the pilot light nozzle.

Once you feel that the knob is in the correct position, press and hold it down and slowly light the pilot light with a match or lighter. You need to hold it down continuously to allow the flame to ignite the gas. When you see a small blue flame, release the knob.

Adjust the flame by turning the knob in the clockwise direction. Once in position, you may hear a “click” indicating it has been set correctly.

Finally, replace the access panel and turn the gas supply back on, however keep in mind the pilot light is still on so you may need to wait a few minutes before activating the furnace.

Lighting a furnace pilot is not something to be taken lightly. If you have any doubts about your ability to do so correctly, always turn to a licensed professional. With a few tips, you’ll be able to safely light your furnace pilot and enjoy the warmth and comfort of your home to the fullest.
