Wall furnaces are an efficient and cost-effective way to heat your home in the chilly winter months. However, if you’re new to using a wall furnace, you may be unsure about how to properly light it. In this guide, we will walk you through the step-by-step process of lighting a wall furnace, ensuring you can enjoy a warm and cozy home.

Step 1: Safety First

Prior to lighting your wall furnace, it’s crucial to ensure your safety. Turn off all electrical power to the furnace and make sure there are no flammable materials nearby. Additionally, check for any gas leaks by using a gas leak detector or soapy water solution on the gas connections. If you detect a leak, immediately call a professional technician.

Step 2: Locate the Pilot Light

Next, locate the pilot light assembly on your wall furnace. It is usually located near the bottom of the unit and can be identified by a small knob or button labeled “Pilot” or “Light.” Take a moment to familiarize yourself with the different components of the pilot light assembly.

Step 3: Turn Off the Gas Valve

Before attempting to light the pilot light, ensure that the gas valve is in the “Off” position. This will prevent any gas from flowing while you are trying to ignite the pilot light. The gas valve is typically located near the bottom of the furnace and can be turned off by rotating it counterclockwise.

Step 4: Prepare to Light the Pilot Light

Once the gas valve is turned off, give the furnace a few minutes to allow any accumulated gas to dissipate. This will help prevent any potential hazards. While you wait, gather a long-reach lighter or a fireplace match and keep it within reach.

Step 5: Lighting the Pilot Light

Now it’s time to light the pilot light. Turn the gas valve to the “Pilot” position and press and hold the pilot button or knob. While holding it down, use the lighter or match to ignite the pilot light. Keep the button or knob depressed for about 30 seconds to allow the thermocouple to heat up.

Step 6: Test the Pilot Light

After holding the pilot button for the designated time, release it and observe the pilot light. It should remain lit. If the pilot light goes out, wait for a few minutes and repeat steps 5 and 6. If the pilot light still does not stay lit, there may be an issue with the thermocouple or gas supply, and a professional should be consulted.

Step 7: Turn On the Gas Valve

Once the pilot light is lit and stable, turn the gas valve back on by rotating it clockwise to the “On” position. This will allow gas to flow to the main burners of the wall furnace.

Step 8: Adjust the Temperature

You can now adjust the temperature on your wall furnace to your desired comfort level. Most wall furnaces have a thermostat or temperature control knob that allows you to set the desired temperature. Experiment with different settings to find the optimal temperature for your home.

Step 9: Maintenance Tips

Regular maintenance is key to ensuring the efficient and safe operation of your wall furnace. Schedule annual professional inspections and cleanings to keep your furnace in top condition. Additionally, replace the furnace filter as recommended by the manufacturer to maintain proper airflow.

Step 10: Enjoy a Warm and Cozy Home

With your wall furnace successfully lit and properly maintained, you can now enjoy a warm and cozy home throughout the winter season. Stay comfortable and save on energy costs by using your wall furnace efficiently.

Remember, if you ever encounter any issues or are unsure about any aspect of lighting or maintaining your wall furnace, it’s always best to consult a professional technician for assistance. Safety should always be the top priority when dealing with gas-powered appliances.
