Dear All, Campingaz Bistro 2 requires a butane cartridge. I can only find lpg gas cartridges (70% butane 30% propane mix) Since the lpg cartridges have higher pressure, the stove's security system trips. To overcome this, put the cartridges in deepfreezer for a few minutes. Cooling down the cartridge decreases the internal pression. Once the stove is lit, the cardtidge cools down fufther. By doing so I xan use cheap cadtridges widely available here. Once the gas level in the cardridge halves you csn ignore cooling step
