Manual pilot lighting when the ignition button doesn't work

If your gas fireplace has no ignition button or the button is broken, you can light the pilot by hand using a long lighter or match. The process is straightforward: turn the control knob to the pilot position, hold a flame near the pilot burner opening while you press and hold the knob, and wait for the flame to catch. Once it does, keep holding the knob for 30 to 60 seconds so the thermocouple (a heat-sensing device) warms up enough to keep the gas flowing.

The key is understanding that you are not bypassing any safety system—you are straightforward providing the spark or flame that the button would normally provide. The thermocouple still does its job: if the pilot goes out, it shuts off the gas supply to prevent dangerous buildup.

Key Takeaways

  • A long lighter or long fireplace match works better than a regular match because it keeps your hand farther from the flame.
  • Turn the control knob to "Pilot" (not "On"), then hold the flame to the pilot burner opening while pressing the knob inward.
  • Keep holding the knob for 30 to 60 seconds after the pilot lights so the thermocouple heats up and locks in the flame.
  • If the pilot will not stay lit after you release the knob, the thermocouple may be failing and you should call a technician.

Gather the right tools before you start

You need a source of flame that reaches into the fireplace safely. A long lighter (the kind made for grills or fireplaces) is the easiest choice because the nozzle extends 6 to 8 inches, keeping your hand well back from the heat. A long fireplace match works too, though it is slower to light and burns down faster. Do not use a regular match or a short lighter—you will burn your fingers or hand.

Before you begin, make sure the fireplace is off and has cooled for at least 15 minutes. Open the fireplace door or access panel so you can see the pilot burner clearly. The pilot burner is a small opening, usually near the bottom of the firebox, with a tiny nozzle pointing upward or to the side.

The step-by-step process

Step 1: Locate the control knob. This is usually on the front of the fireplace or on a panel inside the door. It has positions marked "Off," "Pilot," and "On" (or sometimes "Ignition"). Turn it all the way to "Pilot."

Step 2: Press and hold the knob inward. Pushing the knob in opens the gas valve to the pilot burner. You must hold it down the entire time you are lighting and for 30 to 60 seconds afterward. If you release it too soon, the pilot will go out.

Step 3: Bring the flame to the pilot opening. Light your long lighter or match and hold the flame directly over or beside the pilot burner opening. The exact position depends on which way the nozzle points—look for where the gas is flowing out. The flame should ignite the gas within a few seconds.

Step 4: Hold the knob down while the pilot burns. Once the pilot is lit, keep pressing the knob inward for 30 to 60 seconds. This allows the thermocouple to heat up. You will see the pilot flame grow steadier and brighter as it warms.

Step 5: Release the knob slowly. After 30 to 60 seconds, carefully release the knob. The pilot should stay lit. If it goes out when ready, wait a minute and try again—sometimes the thermocouple needs a longer warm-up. If it keeps going out, the thermocouple is likely worn out.

Why the pilot goes out and what to do

If you light the pilot but it dies as soon as you release the knob, the thermocouple is not warming up enough to signal the gas valve to stay open. This happens when the thermocouple is dirty, bent, or failing. Try lighting it again and holding the knob for a full 60 seconds instead of 30. If it still does not hold, the thermocouple needs cleaning or replacement.

A thermocouple is a small metal rod that sits in the pilot flame. As it heats, it generates a tiny electrical signal that tells the gas valve "the pilot is burning, keep the gas on." If it is coated with dust or soot, it cannot heat properly. If it is bent so the flame does not touch it, it will not work. If it is straightforward old, it may have lost sensitivity.

You can try cleaning it yourself by gently wiping the tip with a dry cloth or soft brush, but if that does not work, you will need a technician to replace it. A failing thermocouple is not something to ignore—it is a safety device, and a fireplace without a working one should not be used.

Safety checks before you light

Before you attempt to light the pilot, smell the area around the fireplace. If you detect a strong gas odor, do not light anything. Turn off the control knob, open windows, and call your gas company or a technician. A gas smell means there is a leak somewhere in the system.

Make sure the fireplace has been off for at least 15 minutes before you start. This allows any residual gas to clear. If you smell gas but it is faint, wait longer and try again. Never light a pilot if you are unsure whether gas is flowing safely.

Keep your face and body back from the fireplace opening while you light the pilot. The flame should be small and contained, but it is still fire. Wear long sleeves if possible, and tie back long hair.

When to call a professional instead

If the pilot will not light at all after several attempts, or if it lights but the main burners will not turn on afterward, something is wrong with the gas line or the valve system. Do not keep trying—call a technician. Repeatedly attempting to light a pilot that will not stay lit can waste gas and create a safety hazard.

If you smell gas during or after lighting, turn off the fireplace when ready, open windows, and call your gas company's emergency line. Do not use the fireplace again until a professional has checked it.

If the control knob is cracked, stuck, or will not turn to the "Pilot" position, the valve itself may be damaged. A technician will need to inspect or replace it. This is not a repair you can do by hand.

Frequently Asked Questions

How long should I hold the knob down after the pilot lights?

Hold it for 30 to 60 seconds. The longer hold gives the thermocouple time to heat up and generate enough signal to keep the gas valve open. If 30 seconds is not enough and the pilot goes out, try 60 seconds next time.

Can I use a regular lighter or match instead of a long lighter?

You can use a regular match, but it is risky—your fingers will be very close to the flame and the match burns down quickly. A long lighter is much safer. Never use a short lighter; you will burn your hand.

What if the pilot lights but goes out when I turn the knob to "On"?

This usually means the thermocouple is not working properly. Try lighting the pilot again and holding the knob longer (up to 90 seconds) to give it more time to heat. If the problem continues, the thermocouple needs to be replaced by a technician.

Is it normal for the pilot to take a few seconds to light?

Yes. Gas takes a moment to flow and ignite. If it takes more than 10 seconds, or if it does not light at all after several tries, there may be a blockage in the pilot line or a problem with the gas supply.

Can I light the pilot if I smell a faint gas odor?

No. Any gas smell means there is a leak or buildup somewhere. Open windows, turn off the fireplace, and call your gas company or a technician before attempting to light anything.
