Introduction

If you have an old furnace in your home, it’s important to know how to properly light it to ensure your comfort and safety during the colder months. While newer furnaces typically have electronic ignition systems, older models may still require manual lighting. In this article, we will provide you with a step-by-step guide on how to safely and effectively light an old furnace in the year 2023.

Gather the Necessary Tools and Materials

Before attempting to light your old furnace, gather the following tools and materials:

  • A flashlight
  • A long fireplace match or butane lighter
  • Protective gloves

Locate the Pilot Light

Start by locating the pilot light on your old furnace. It is usually located at the bottom of the furnace near the burner assembly. Use your flashlight to get a clear view of the area.

Turn Off the Gas

Prior to lighting the furnace, ensure that the gas supply is turned off. Locate the gas valve near the furnace and turn it to the “off” position. This will prevent any accidents or gas leaks during the lighting process.

Prepare for Lighting

Put on your protective gloves to shield your hands from any potential burns. Make sure there are no flammable materials near the furnace and ensure proper ventilation in the area.

Find the Pilot Light Control Knob

Locate the pilot light control knob on your furnace. It is usually labeled and can be found near the gas valve. Turn the knob to the “pilot” position.

Ignite the Pilot Light

Using your long fireplace match or butane lighter, carefully ignite the pilot light. Hold the flame near the pilot light assembly while slowly pushing down on the control knob. This will release a small amount of gas to ignite the pilot light.

Keep Holding the Control Knob

After igniting the pilot light, continue to hold down the control knob for about one minute. This allows the thermocouple to heat up and maintain the flame. If the pilot light goes out after releasing the control knob, repeat the process.

Switch to the “On” Position

Once the pilot light is stable, turn the control knob to the “on” position. This will allow the gas to flow to the main burner, providing heat to your home. Check that the burner ignites properly.

Test the Furnace

Now, test your furnace by adjusting the thermostat to the desired temperature. The main burner should ignite and start distributing warm air throughout your home. If the furnace fails to function properly, consult a professional HVAC technician.

Conclusion

Lighting an old furnace may seem daunting at first, but by following these step-by-step instructions, you can safely and effectively light your furnace in the year 2023. Remember to exercise caution, wear protective gloves, and seek professional help if needed. Stay warm and comfortable throughout the cold season!
