PROBLEM TO BE SOLVED: To solve a problem wherein gasoline is filled erroneously to cause fire disaster because a cartridge tank for a conventional petroleum fan heater or stove has no erroneous gasoline feed alarm display. SOLUTION: An erroneous gasoline feed alarm display window is provided in this cartridge tank. A color separation discriminator is installed in structure of the cartridge tank. It uses a principle that gasoline is lighter than kerosine, and mixed oil is separated with the lapse of time to bring a gasoline layer in its upper layer, as an action thereof. A vermilion color in a top part is continued to be displayed as far as the kerosine in a lower layer does not reach a lower part of the color separation discriminator, even when the kerosine is consumed to reduce its amount.
