  • If the flame dial is still adjusted to the lowest setting after refilling the lighter.
  • While injecting fuel into the torch, it maybe that too much air has got trapped inside the fuel container of the torch.
  • You didn’t bleed the lighter properly before refueling it.

How do you refill a torch with butane?

Before refilling a torch with butane, you have to evacuate the existing butane. And use the right butane fuel in the correct way to refill the torch. Here is a step-by-step guide of butane torch refilling.

Things required

  • A running butane torch
  • A canister of a good quality butane (with metal fill tip nozzle)
  • A flat-blade screwdriver
  • A table or desk (this is optional. You can work on a concrete floor too).
  • Newspaper or cloth.

Additional requirements

  • Safety equipment (gloves, goggles, mask).
  • If you can’t afford safety equipment, hold the lighter and the canister away from your face.

Step 1 – Cool down the torch

First of all, cool down the torch at room temperature for at least 30 minutes or in the refrigerator for 5 minutes. If you immediately refill it just after the previous use, it will catch fire.

Step 2 – Prepare the workspace

Choose an open and well-ventilated place for evacuating and refilling a butane torch. And the working surface must be clean, dry, stable, and sturdy. Butane sprays everywhere when filling torch, so cover the surface with some newspaper or clothes before the task.

Step 3 – Turn the flame dial

Find out the flame-adjusting dial in the torch. Now take a small flat-blade screwdriver and turn the dial to the minimum setting in a clockwise motion. If the torch has a special key or wheel to adjust the dial, don’t use a screwdriver.

Step 4 – Purge the remaining gas

Push down the refilling valve with the screwdriver to let out the remaining butane fuel of the torch. When the hissing sound will stop, leave the valve. Wait for 5 minutes after bleeding the torch.

Step 5 – Prepare the butane canister

Take the canister of the butane gas and shake it well, at least 5-6 times. Because inside the canister, there is the butane and a propellant. Shaking will help the heavier butane at the bottom to come upward.

Step 6 – Hold the torch correctly

Now it’s time to inject the butane. Hold the torch upside down. Doing this will prevent the air from getting into the torch.

Step 7 – Connect the stem and the valve

Hold the canister upside down and press the stem of the canister tightly over the valve of the torch. Most importantly, while doing this, both the torch and the canister must be straight, not angled. Otherwise, air will get into the torch.

Step 8 – Refill the torch

Pump the canister a few times to refill the torch. Generally, it takes two or three 3-second bursts to fill the required butane into the torch. Make sure not to overfill the torch.

Step 9 – Readjust the flame dial

After spraying the fuel, remove the canister and turn the flame adjusting dial to the medium setting.

Step 10 – Let the butane to adjust

Refueling is done. Now wait for some time so that the refilled butane can adjust with the room temperature. Also, if there is any spilled butane outside the torch, it will be able to evaporate. For a better ignition, you can hold the torch in your palm for a few minutes to warm it up.

Step 11 – Taste the torch

Turn on the torch. You need to turn on and off the torch a few times to get a smooth flaming. You can turn the flame adjuster to your preferred setting.

Why isn’t my torch filling up with butane?

Why isn’t my torch filling up with butane?

Because you might have used a low-quality butane gas to fill your torch. Or, maybe your torch is clogged.

Butane lighters require an ultra-refined butane to perform. The more refined the gas is, the more smoothly it will get into the fuel container of the torch and cause no clogging.

You are trying to refuel your torch with a premium butane (which has a metal fill nozzle) but your torch is not responding? Then try to remember which butane you were using in your torch in the past.

If the torch jet shows clogging or corrosion, it proves that you might have used a non-premium butane to fuel it before. Non-premium butane comes with a plastic fill tip nozzle. It does not provide the same level of pressure as the premium butane with a metal fill tip nozzle. As a result, the torch performs inconsistently and experiences issues.

Another reason can be that you are using a N-butane to fuel your torch. N-butane is an iso-butane with lower vapor pressure. Since the butane torch requires higher vapor pressure, n-butane won’t flow into the torch easily.

Sometimes, air can cause the faulty filling of the torch. While injecting butane, if you angle the lighter or the canister, air will get into the lighter and occupy the blank space.
