Lighting your gas fireplace pilot light is a simple process that anyone can master with a bit of patience. By following these clear steps, you can safely restore warmth to your living room and ensure your home stays comfortable throughout the colder months.
There is nothing quite like the cozy glow of a gas fireplace on a chilly evening. However, if your pilot light has gone out, that warmth quickly turns into a cold, dark fireplace. Many homeowners feel a bit nervous about dealing with gas appliances, but learning how to light fireplace pilot light is a manageable task if you follow the right safety procedures. Whether you are prepping for the first frost or troubleshooting a mid-winter outage, this guide will walk you through the process step by step.
Before we dive into the “how-to,” it is helpful to understand what is a gas fireplace. These units are designed for convenience and efficiency, but they do require a constant, small flame—the pilot—to ignite the main burner. When this light goes out, your fireplace becomes a decorative box until you reset the flame. Let us get your fire back up and running safely.
Key Takeaways
- Safety First: Always smell for gas before you attempt to ignite the pilot light to ensure there are no leaks.
- Locate the Controls: Every fireplace has a control knob that usually features “On,” “Off,” and “Pilot” settings.
- Wait for Air to Clear: If the unit has been off for a long time, give it a few minutes for fresh gas to reach the pilot assembly.
- Hold the Button: You must keep the pilot knob depressed long enough for the thermocouple to heat up and signal the valve to stay open.
- Know Your Model: Some fireplaces use an electronic ignition system, which requires a different approach than traditional standing pilots.
- Professional Help: If you smell gas or cannot get the pilot to stay lit, call a certified technician immediately.

Preparation and Safety Checks
Before you even touch the control knob, you must ensure the area is safe. Gas can be dangerous if handled incorrectly, so your first priority is to check for leaks. If you smell a strong, rotten-egg odor, do not attempt to light the pilot. Evacuate the house and call your utility company immediately.
Finding the Pilot Assembly
Most gas fireplaces hide the control valve behind a decorative panel, a bottom louvered grate, or a small door at the base of the unit. You might need to gently pull or lift this panel to see the control box. Once you open it, you will see a dial with labels like “Pilot,” “On,” and “Off,” along with a red or black igniter button. If you have been looking into how fireplace works, you likely already know that this pilot light is the heart of your system.
Step-by-Step Guide to Lighting the Pilot
Now that you have located your controls, it is time to light the pilot. Follow these steps carefully and stay patient. Sometimes it takes a few tries to clear air out of the gas lines.
1. Turn the Knob to “Pilot”
Ensure the main control knob is rotated to the “Pilot” position. This allows gas to flow only to the small pilot tube rather than the main burner. If there is a separate On/Off switch for the wall, make sure it is set to “Off” while you perform this task.
2. Press and Hold the Knob
Push the pilot knob inward. By holding it down, you are manually forcing gas into the pilot burner assembly. While holding it down, press the igniter button repeatedly. You should hear a clicking sound and see a small spark inside the pilot chamber. If you do not have an igniter button, you may need to use a long-reach fireplace lighter.
3. Maintain the Hold
Once you see the tiny blue flame flicker to life, do not let go of the knob yet! You must hold the knob down for about 30 to 60 seconds. This allows the thermocouple to get hot. The thermocouple is a small safety device that senses heat; once it is hot enough, it tells the gas valve to stay open automatically.
Troubleshooting Common Issues
Sometimes, the pilot light simply refuses to stay lit. This can be frustrating, but it is often caused by a few common, minor issues. If your light goes out the moment you release the knob, the thermocouple is likely not getting hot enough or may need to be cleaned.
Cleaning the Thermocouple
Over time, soot and carbon buildup can insulate the thermocouple, preventing it from sensing the flame correctly. Use a soft cloth or a very light-grit sandpaper to gently wipe the tip of the thermocouple. This small adjustment often fixes the problem instantly. Once cleaned, try the lighting process again from the start.
Checking for Drafts
If you are still struggling, remember that outdoor air could be blowing the pilot out. While it is good to know how to install fresh air intake for fireplace units to improve efficiency, a poorly sealed intake can sometimes create a draft that extinguishes a small pilot flame. Ensure the glass front of your fireplace is securely sealed to prevent these gusts from affecting the pilot.
When to Call a Professional
While lighting a pilot is usually a DIY project, there are times when you should leave it to the pros. If you have tried these steps several times and the pilot still will not stay lit, you might have a faulty thermocouple, a bad gas valve, or a clogged pilot orifice. Do not try to force or take apart the gas valve yourself, as this can lead to dangerous leaks.
Maintaining Your Fireplace Performance
Keeping your pilot light burning is just one part of fireplace maintenance. Regular cleaning and inspections will extend the life of your unit. Every season, check the burner holes for dust, clean the glass, and inspect the venting. A well-maintained fireplace is not only safer but also provides a more consistent, beautiful flame every time you turn it on.
Conclusion
Learning how to light fireplace pilot light is a valuable skill for any homeowner with a gas hearth. By following these steps—checking for gas odors, holding the button long enough for the thermocouple to heat up, and troubleshooting minor debris issues—you can keep your home warm and inviting. Remember, if you ever feel uncomfortable or smell something unusual, reach out to a professional. Enjoy the cozy comfort of your fireplace all season long!
Frequently Asked Questions
Why does my pilot light keep going out?
The most common reason is a dirty or faulty thermocouple, which prevents the gas valve from staying open. It could also be caused by a draft in the firebox or an issue with the gas pressure in your home.
How long should I hold the pilot knob down?
You should hold the knob down for at least 30 to 60 seconds after the pilot flame appears. This ensures the thermocouple is sufficiently heated to keep the gas flow active.
Can I use a regular lighter to light the pilot?
Yes, you can use a long-reach utility lighter if your fireplace igniter is broken or not sparking. Always be careful to keep your hand clear of the burner area once the flame is lit.
Is it safe to leave the pilot light on all summer?
It is generally safe, but many people turn it off during the summer to save on gas costs. However, keeping it on can help prevent rust and moisture buildup inside the burner assembly.
What if I smell gas while lighting the pilot?
Stop immediately, turn the control knob to the “Off” position, and leave the area. If the smell persists, leave your home and call the gas company or a licensed technician from a safe distance.
How often should I service my gas fireplace?
It is recommended to have a professional inspection once a year before the start of the heating season. This ensures all safety sensors are functioning and the internal components are free of debris.
