How to Light the Pilot on a Gas Furnace
Gas furnaces are a common heating solution in many homes, providing efficient and reliable warmth during the cold winter months. However, when the pilot light goes out, it can be frustrating and even unsafe. In this article, we will guide you on how to light the pilot on a gas furnace. Follow these steps to restore heat to your home quickly and safely.
Before You Start
Before attempting to light the pilot, make sure you have taken the necessary safety precautions:
- Turn off the power: Switch off the power to the furnace at the circuit breaker or fuse box to prevent any accidental startups.
- Make sure the furnace is cool: Ensure the furnace is completely cool before attempting to work on it.
- Wear protective gear: Put on safety glasses, a face mask, and gloves to protect yourself from dust, debris, and potentially hazardous gases.
Gather Essential Tools and Parts
Before starting the process, gather the following tools and parts:
- Pilot light igniter: This is usually located near the pilot light.
- Pilot light orifice: This is the small opening where the pilot light burns.
- Pilot light adjusting screw: This is used to adjust the pilot light’s flame height.
- Matches or a pilot light lighter: Use matches or a pilot light lighter to ignite the pilot.
- Furnace manual: Have the manufacturer’s manual handy for specific instructions and diagrams.
Step-by-Step Guide to Lighting the Pilot
Follow these steps to light the pilot on your gas furnace:
- Locate the pilot orifice: Find the pilot orifice, usually located at the bottom of the furnace or near the pilot light.
- Clear the orifice: Use a small brush or cloth to clean out any debris or dust that may be blocking the pilot light’s flow.
- Adjust the orifice: Use a screwdriver to adjust the orifice to the recommended setting specified in the furnace manual.
- Light the pilot: Hold a match or use a pilot light lighter near the pilot orifice to ignite the pilot. You may need to adjust the orifice a few times to get the pilot to light.
- Adjust the pilot flame: Use the pilot light adjusting screw to adjust the flame height to the recommended setting in the furnace manual.
- Check the pilot: Verify that the pilot is burning steadily and adjust the orifice or flame height as needed.
Troubleshooting Common Issues
If the pilot light does not stay lit, check the following common issues:
- Incorrect pilot orifice adjustment: Double-check the orifice setting and adjust as needed.
- Clogged or dirty pilot orifice: Clean out the orifice with a small brush or cloth.
- Malfunctioning pilot light igniter: Replace the igniter if it is not functioning properly.
- Incorrect pilot flame height: Adjust the flame height using the pilot light adjusting screw.
Additional Tips and Precautions
When working with gas furnaces, it is essential to follow these additional tips and precautions:
