Firstly, be sure to stay away from external heat sources when using it; Secondly, confirm if the gas cylinder is being used for the first time and check for any air leaks at the interface before ignition; Finally, it is recommended to use up the gas tank of the card furnace within 2-3 years.

In daily life, it is necessary to regularly maintain the card furnace, and the gas cylinder must be stored in a cool and dry place to avoid squeezing and colliding. Butane gas cylinders should be stored in a cool, ventilated place with a temperature not exceeding 30 ℃, away from sources of fire and heat, and protected from direct sunlight. They should be stored separately from oxygen, compressed air, oxidants, etc. The lighting, ventilation and other facilities in the storage room should be explosion-proof, and the switches should be located outside the room. When the gas in the gas tank of the card furnace is not used up, the gas tank should not be discarded at will.

In addition, besides paying attention to the safety of using butane gas cylinders, it is also necessary to pay attention to the selection of cookware. It is not recommended to use large-sized trays when using a card furnace. Large trays can easily cause heat accumulation, and gas cylinders may expand and explode when heated. Secondly, large trays are prone to tilting, which may cause burns to consumers.
