These stoves work great with kerosene or diesel There are 8 wicks that rest in the bottom pan, which is filled with fuel. A wick raiser and lowerer controls the flame. Included with the stove are the wicks that are in it when it ships, plus a bag of 48 extra wicks. Cotton mop heads may also be used for wicks. Exclusively outdoor use on a flameproof surface, as they do get hot once they are going, and the fuel will be above ignition temperature.
