Does My Pilot Light Always Stay Lit?

When should I light my fireplace pilot light each year?

🔥 The short, practical answer

Light your pilot light when you’re ready to start using the fireplace consistently for fall/winter. Keeping it lit during the season keeps the system warm, dry, and ready to ignite instantly.

🧭 Why timing matters

• Moisture control: A lit pilot keeps the firebox slightly warm, preventing condensation and corrosion inside the gas valve and burner orifices.
  
  
• Reliability: The thermocouple/thermopile stays warm and powered, so the main burner responds instantly when you flip the switch.
  
  
• Ease of use: If you wait until the first cold night, you may find the pilot won’t stay lit due to dust, moisture, or a cold thermocouple.
  
  

🕰️ Seasonal rule of thumb

• Fall → Light it When nights start dipping into the 40s/50s and you know you’ll want the fireplace soon.
  
  
• Winter → Keep it lit Manufacturers often recommend leaving it on throughout the heating season for reliability.
  
  
• Spring/Summer → Turn it off If you want to save a few dollars in gas, shut it down when you’re done for the season.
  
  

🛑 Safety reminder

If your pilot won’t stay lit, or you smell gas, stop and troubleshoot or call a pro. Pilot‑light failures are the #1 gas‑fireplace service call.
