How to Light a Kerosene Heater (Igniter)
This video shows how to light a Kero-World KC2404 heater. See our picks for the best portable kerosene heater here.
1. Read Instructions Manual
Always read the instruction manual before lighting your kerosene heater. Make sure it is assembled properly.
2. Fill Tank with Kerosene
The heater should be COOL when you fill it. Never fill a kerosene heater while it is still warm.
3. Open Hatch
Open the little window so you can see what is going on.
4. Adjust Wick
The wick is cylindrical and made out of cotton or fiberglass. It dips into the fuel tank and soaks up kerosene. There is usually a knob that adjusts the wick length. Use this to turn your wick to the very top.

5. Press Igniter
Hold the igniter until the wick is completely lit. (See below for instructions on how to light the wick manually.)
6. Stabilize Burner
Once the wick is lit, close the burner. You’ll need to move it back and forth a bit to make sure it is properly seated. If it isn’t seated correctly, the heater will make a nasty smoke and smell bad.
7. Close Hatch and Watch
You’ll need to keep an eye on the flame for at least 10 minutes. The flame will start to change height and get higher. As it does, you’ll need to use the knob to reduce the wick height.
Adjust the wick height, so the flame is ½ inch above the top of the burner. If the flame gets too high, you could have carbon monoxide gas and bad smells. If the flame is too low, you will get soot and bad smells.

- Turn up wick to high
