How do You Light the Pilot on a Furnace?
Lighting the pilot on a furnace is a crucial step in ensuring that your heating system functions efficiently and safely. In this article, we will provide you with a step-by-step guide on how to light the pilot on a furnace.
Before You Begin
Before attempting to light the pilot, make sure you have the following:
- A clear understanding of the furnace’s lighting instructions
- The furnace’s manual
- A pair of gloves
- A flashlight or other light source
- A timer (optional)
Locating the Pilot
The first step in lighting the pilot is to locate it. The pilot is usually a small, removable plate or valve located near the burners. You can find the pilot by looking at the furnace’s control panel or consulting the manual. Make sure to turn off the power to the furnace before attempting to locate the pilot.
Step-by-Step Instructions
Step 1: Remove the Pilot Shield
To access the pilot, you need to remove the pilot shield or cover. This is usually a simple process that involves turning a screw or lifting a latch. Make sure to turn off the gas supply to the furnace before attempting to remove the shield.
Step 2: Turn On the Gas Supply
Turn the gas supply valve to the "pilot" position. This will allow gas to flow to the pilot.
Step 3: Light the Pilot
Hold a flame from a lighter or match to the pilot orifice. Make sure to hold the flame steady and avoid blowing it out. If the pilot does not light, try cleaning the pilot orifice with a cloth or brush.
Step 4: Adjust the Pilot
Once the pilot is lit, adjust it by turning the pilot adjuster clockwise or counterclockwise until the pilot is burning steadily.
Step 5: Light the Main Burner
Turn the gas supply valve to the "run" position and light the main burner. Make sure to light the main burner when the pilot is burning steadily.
