How to Light Your Furnace Safely and Effectively: 1 Minute to a Warm Home with These Easy Steps

Lighting your furnace safely and effectively is crucial for both comfort and security in your home. The process can vary slightly depending on the type and age of your furnace—older models may have a standing pilot light, while newer furnaces often use electronic ignition. Regardless of the system, it’s important to follow safety precautions and manufacturer instructions to prevent accidents. Here’s how you can light your furnace and ensure it operates efficiently:

1. Turn Off the Gas and Power: Before you do anything, make sure the furnace’s power switch and the gas valve are turned off. Allow any residual gas to dissipate for a few minutes to prevent ignition hazards.
2. Locate the Pilot Light or Ignition System: Open the access panel to find the pilot light assembly or the electronic ignition. Make sure your furnace's thermostat is set to the lowest temperature.
3. Refer to the Manufacturer’s Instructions: Each furnace model has specific lighting instructions. Read the label on your furnace or the user manual carefully.
4. Lighting the Pilot (for Manual/Pilot Light Models):
5. Turn the gas control knob to “pilot.”
6. Hold down the reset button and use a long lighter or match to ignite the pilot.
7. Keep the button pressed for 30 seconds, then slowly release. The pilot should stay lit.
8. If the pilot does not stay lit, wait a few minutes and repeat. If it still doesn’t light, call a professional.
9. Electronic Ignition: For furnaces with electronic ignition, simply turn on the furnace following the manufacturer’s guidelines. The system will automatically ignite when needed.
10. Turn On Gas and Power: Once the pilot is burning or the ignition system is ready, restore power and set the gas valve to “on.” Adjust the thermostat to the desired setting.
11. Observe Operation: Watch the furnace for a few cycles to ensure the burners ignite smoothly and the system is working efficiently.
