How to Relight a Pilot Light on a Gas Fireplace

If your gas fireplace won't light, you might need to relight the pilot light. Following the right safety protocol is crucial when working with any gas appliance. This guide walks you through the relighting process step by step.
Important Safety Warning:
Before attempting to relight a pilot light on your gas fireplace, check for the smell of gas. If you detect any gas odor, leave your home immediately and call your gas company. Never attempt to light a pilot if you smell gas.
What You'll Need
You'll need a long lighter or fireplace match to relight your pilot light. Keep your fireplace owner's manual nearby if you have it. The manual shows the exact location of your pilot light and control valve.
Finding Your Pilot Light
Most gas fireplaces have the pilot light assembly near the bottom of the unit. Look for a small metal tube with a tiny opening at the end. You'll also find the gas control valve here, usually marked with "On," "Off," and "Pilot" settings.
Step-by-Step Pilot Relighting Instructions
1. Open the Fireplace
First, remove your fireplace's decorative front panel or screen. This gives you clear access to the pilot light assembly. Turn off your fireplace's gas valve and wait five minutes to let any remaining gas clear.
2. Set the Control Valve
Turn the control valve to the "Pilot" setting. This position allows just enough gas flow to light the pilot. Some models require you to press and hold the valve in this position.
3. Light the Pilot
While holding the valve in the pilot position, bring your lighter flame to the pilot light opening. Hold the valve down for about 30 seconds after the pilot lights. This heats the thermocouple and keeps the pilot lit when you release the valve.
4. Turn On the Control Valve
Once the pilot stays lit, turn the control valve to the "On" position. Replace the front panel or screen. Your fireplace should now work normally with its regular controls.
If the Pilot Won't Stay Lit
When a pilot light won't stay lit after several attempts, you likely have a bigger issue. Common problems include:
- Thermocouple Issues: The thermocouple monitors your pilot flame. If it's dirty or faulty, it won't keep the gas flowing to your pilot light.
- Gas Flow Problems: Dirty pilot openings or low gas pressure can prevent proper pilot light operation.
- Safety Control Failure: Modern gas fireplaces have several safety controls. If any fail, they might prevent the pilot from staying lit.
When to Call a Professional
Stop trying to light your pilot and call a fireplace expert if:
- The pilot won't stay lit after three attempts
- You hear unusual sounds
- You notice any gas smells
- Your fireplace shows signs of damage
- You feel uncomfortable with the process
