An apparatus comprising:
- a fuel reservoir with a front surface, a back surface, and a bottom surface having a flattened portion;
- an air channel extending through the fuel reservoir between the front surface and the back surface;
- a wick assembly, mounted within the air channel, comprising:
- a wick with a hollow center;
- and
- a wick sleeve conforming to the wick, the wick sleeve comprising an inner wall and an outer wall,
- wherein the wick sleeve is adapted such that the wick is slidably received by a first end of the wick sleeve and wick travel is stopped by a second end of the wick sleeve;
- a fuel tube connecting the fuel reservoir and the second end of the wick sleeve through a fuel opening in the second end of the wick sleeve, such that the wick is in fluid communication with the fuel reservoir;
- and
- a fuel valve for controlling the flow of fuel through the fuel tube,
- wherein the flattened portion of the fuel reservoir is adapted to position the wick assembly parallel to a horizontal surface when the flattened portion rests on the horizontal surface and the top portion of the reservoir is sized narrower than the bottom portion.
