How to Light a Wall Furnace Pilot?
Introduction
Lighting a wall furnace pilot can be a daunting task, especially for those who are new to furnace operation. However, with a few simple steps and understanding the basics, you’ll be able to light the pilot successfully. In this article, we’ll take you through the process, highlighting the key steps, and providing tips and advice to ensure a smooth ignition.
Understanding the Basics
Before we dive into the steps, it’s essential to understand the fundamental components of a wall furnace pilot. A pilot light is a small flame or spark that ignites the main burner, providing a continuous heat source. A wall furnace pilot typically consists of:
- Control Valve: Regulates gas flow to the pilot assembly
- Pilot Assembly: Includes the orifice, pilot jet, and ignition electrode
- Thermocouple: A temperature-sensing device that maintains the pilot flame

Step 1: Ensure Safety Measures
Before attempting to light the pilot, ensure your safety:
- Switch off the power: Electric furnaces: turn off the main power switch.
- Gas furnaces: close the gas shutoff valve.
- Wear protective gear: gloves, safety glasses
Step 2: Clean the Pilot Area
Clean the pilot assembly and surrounding area to:
- Remove debris and dust
- Dampen the pilot tube (if applicable) to prevent gas leaks
- Check for cracked or damaged components
Step 3: Set the Control Valve
Adjust the control valve to:
- Minimum setting: prevent excessive gas flow
- Turn the valve slightly counterclockwise
Step 4: Light the Pilot
There are two methods to light a wall furnace pilot:
Method 1: Using a Lighter
- Hold the flame of a lighter (not a match) on the pilot jet for:
- 5-10 seconds for Natural Gas
- 10-15 seconds for Propane
- Wait for ignition: you’ll see the pilot light flicker on
- Adjust the control valve: clockwise until the pilot flame stabilizes
Method 2: Using an Electrode
- Remove any debris from the ignition electrode
- Hold a metal object (screwdriver, etc.) against the electrode
- Gently touch the electrode to the pilot assembly
- Wait for ignition: you’ll see the pilot light flicker on
- Adjust the control valve: clockwise until the pilot flame stabilizes
Step 5: Confirm the Pilot Flame
Verify the pilot flame is steady, blue, and unchanged. If:
- Flame appears weak or yellow: adjust the control valve: counterclockwise or clockwise as needed
- Flame is faulty or nonexistent: troubleshoot the pilot assembly, thermocouple, or control valve before attempting to relight the pilot
Tips and Troubleshooting
Common Issues:
• Pilot won’t light: check for pilot tube blockages, weak gas supply, or cracked components
• Flame keeps going out: adjust the control valve or check for leaks
• Flame is erratic: check the thermocouple or pilot assembly
Best Practices:
• Regularly maintain your wall furnace: clean filters, inspect gas lines, and check safety devices
• Consider upgrading to a low-maintenance pilot system (e.g., electronic pilot ignition)
Conclusion
Lighting a wall furnace pilot may seem intimidating at first, but by following these steps and understanding the basics, you’ll be able to do it efficiently and safely. Remember to prioritize safety, clean the pilot area, and take your time when adjusting the control valve. With this guide, you’ll be well on your way to successfully lighting your wall furnace pilot.
