The butane gas cartridge contains extremely flammable gas and must be handled with caution. It should be stored in a cool, dry, and well-ventilated place away from heat, sparks, open flames, and temperatures exceeding 50°C. The cartridge must not be exposed to direct sunlight or pierced, punctured, or incinerated—even after use. When changing cartridges, always do so in a well-ventilated area free of ignition sources. Ensure the appliance valve is closed and the cartridge is empty before removal. A damaged or missing connection seal must be replaced before reuse. For safety, leaking gas fires should only be extinguished if the leak can be safely stopped. Always follow the appliance’s operating instructions for correct and safe use.
