How to Light a Furnace: A Step-by-Step Guide
f your furnace has been turned off for an extended period of time, it is important to follow these steps to ensure it is lit correctly and safely.
1. Check your furnace’s oil supply. If you have an oil-fired furnace, you will need to check the oil tank to make sure there is enough fuel for the furnace to operate.
2. Clean the furnace’s burner assembly. An accumulation of dust and debris on the burner can impede proper operation.
3. Place a clean rag over the open end of the oil line that leads to the burner assembly. This will catch any drips of oil that may occur when priming the system.
4. Open the valve that controls oil flow to the burner assembly and allow a small amount of oil to flow into the line.
5. Close the valve and remove the rag from the end of the oil line.
6. Press the reset button on the furnace’s control panel. The furnace’s blower should start and circulate air through the unit.
7. Observe the operation of the furnace for a few minutes to ensure it is running correctly before leaving it unattended.

Then, hold a lighted match near the furnace’s burner opening. If the burner lights, you can adjust the flame by turning the knob on the gas valve. If the burner doesn’t light, make sure there’s no debris blocking the opening and try again. If you still can’t get it to work, call a professional for help.

3. Use a long match or lighter to ignite the pilot light. Hold the flame to the pilot light for about 60 seconds to give it time to heat up and stay lit.
4. Once the pilot light is lit, you can release the button and turn on your furnace.
Why is My Furnace Not Lighting?
f your furnace isn’t lighting, the problem could be with the pilot light. The pilot light is a small flame that ignites the burner in your furnace. If the pilot light goes out, the burner won’t turn on and your furnace won’t heat your home.
There are a few reasons why the pilot light might go out. One possibility is that the pilot light tube is clogged. This can happen if the furnace hasn’t been used in a while and dust has collected in the tube. Another possibility is that there is a draft in the room where the furnace is located. This can happen if there are cracks in the walls or doors or if there is an exhaust fan in the room.
If you think the problem might be with the pilot light, you can try relighting it yourself. First, make sure that the gas valve is turned to “pilot” mode. Then, follow the lighting instructions that came with your furnace. If you can’t get the pilot light to stay lit, you should call a professional to service your furnace.

If the pilot light is still blowing out, there could be a draft in the room that’s causing the problem. To fix this, you can try relighting the pilot light while holding a piece of cardboard or another object over it to block the draft. Finally, if your furnace is old, the pilot light assembly may be worn out and need to be replaced.

4. Once you find the switch or knob, turn it to the “off” position and wait a few minutes. Then, turn it back to the “on” position and hold it down for about 60 seconds. You may hear a clicking sound when you do this.
