How to Refill Your Jet Flame Lighter

What You’ll Need:

S.T. Dupont Black Butane Gas (specifically formulated for jet flame models)
A clean, stable surface

Steps:

Turn the lighter upside down and locate the refill valve.
Use a firm grip and insert the nozzle of the black gas refill into the valve.
Press and hold for about 5 seconds to fill the chamber.
Allow the lighter to rest for a minute or two to stabilize before use.

Note: The black gas is engineered for jet flame lighters and prevents carbon buildup that can clog the system.

How to Ignite the Jet Flame

Jet flame models do not require a flint or strike wheel.
Instead, they operate with a piezo-electric ignition system.

Simply press the ignition button to engage the flame.
A strong, concentrated jet flame will activate instantly.
If the lighter doesn’t ignite on the first click, give it a second or third try—this is normal, especially right after refilling.

Ongoing Maintenance and Care

Use only S.T. Dupont black gas to maintain peak performance. Other fuels may clog the nozzle or void your warranty.
Store the lighter upright and avoid extreme temperatures.
If the flame weakens, check the refill level and refill as needed.
No flint replacement is required—these models are designed for simplified upkeep.

Troubleshooting Tips

Lighter doesn’t ignite? Try clicking it a few more times after refilling.
Weak or sputtering flame? Ensure you’re using black gas and that the nozzle is clear of debris.
No sound or response? The piezo system may be worn and require professional servicing.
