For safety purposes during transportation, most manufacturers do not add butane fuel cans in the package. You can buy butane from most local stores or order them online from manufacturers’ websites. To refill your kitchen blowtorch: 1. Press the fuel-refilling nozzle to get rid of any remaining fuel or air. 2. Turn off the burner and lock the trigger. 3. While holding the torch nozzle perpendicular to the fuel can, insert the tip of the can into the torch’s fuel-refilling nozzle. 4. Fill up the torch to the recommended level then remove the tip of the can from the kitchen torch. 5. Before using it, let the torch rest for a few minutes as the fuel adjusts to room temperature.
