Before use, two preparations need to be made: first, carefully read the instructions, packaging, warning information on the gas cylinder, etc., understand how to operate correctly, and clarify the precautions. The second is to check the condition of the gas cylinder to ensure that it is within its validity period and there is no damage or leakage. It should be noted that the gas cylinder of the card furnace should be used within 2 to 3 years. If it is not used for a long time, it is not recommended to use it again.

After using the card furnace, the gas cylinder should be removed and stored separately from the card furnace. Daily storage of card stoves should be done in a cool and dark place, away from high temperature heat sources and open flames. Card furnace gas cylinders are disposable products and should not be discarded after use. They cannot be refilled and reused. In addition, the bottom of the gas cylinder in the card furnace is relatively thin, which can easily cause damage and gas leakage when subjected to excessive external pressure or collision with hard objects. Once exposed to an open flame, there is a possibility of explosion.

Do not use near flammable materials or curtains. Do not use under scorching sun or in areas with open flames or other heat sources nearby. Do not use a card stove as a heater or in a tightly sealed environment. Do not use in strong or hot winds, as strong winds can extinguish flames and hot winds can increase air pressure, causing explosions.

A card stove, also known as a portable butane gas stove, refers to a non fixed cooking utensil that uses filled butane gas or liquefied gas as fuel for direct heating with fire.

Ordinary models are not windproof; choose windproof versions for outdoor use.

It depends on fire power, usually 2–4 hours.

Please use dedicated butane gas canisters.

They can be used indoors, but ensure good ventilation.
