How to Fill a Butane Torch
Small butane torches can emit flames with temperatures starting at about 1,260 degrees C. (hand held torch image by Tammy Mobley from

Butane torches come in handy for a variety of uses, including starting a fire while camping, lighting candles, caramelising sugar when cooking and making jewellery. You can purchase torches with refill cylinders or disposable torches, and torches come in a variety of shapes and sizes. Refilling a butane torch is much like refilling a butane lighter. When you fill a butane torch, a flint or a piezoelectric ignition spark ignites the butane-gas vapour. The flames can reach temperatures of at least 1,260 degrees C.

  1. 1

    Turn your torch upside down. Although butane torches come in a variety of styles, most have the fuel refill valve located on the bottom of the lighter. The valve looks like a small, round hole. Depress the fuel refill valve using a pen or a small screwdriver. Drain out any fuel it may contain. This also releases any compressed air the tank may have.

  2. 2

    Shut off the fuel flow by turning the flame adjustment screw clockwise, using a small screwdriver. You will usually find this flathead screw located near the fuel refill valve hole, on the bottom of the torch lighter.

  3. 3

    Press the fuel can into the torch with the fuel-can nozzle pointing down. Do not pump the fuel can. It may take a few minutes for the torch to fill.

  4. 4

    Set the torch down and wait until it reaches room temperature before using it. The fuel comes out cold when you refill the torch.

  5. 5

    Turn the fuel flow back on by turning the flame-adjustment screw counter-clockwise a half turn. Try to light your torch. If it does not work, turn the screw in increments of quarter turns until it lights.

Tips and warnings

  • If you have a butane torch lighter, refill it faster by placing the torch lighter in a freezer for a few minutes. Cold lighters refill faster.
  • If you have problems getting your torch to ignite, blow into it to remove any dirt or dust. You also can use compressed air from an office-supply store to blow out dust particles.
  • Use only triple-refined butane fuel. Cheaper butane fuel contains impurities that can clog your torch.
  • Keep butane and butane torches away from children
  • Drain your butane torch away from flames
