0vsinger 9 years ago Converting an old Coleman liquid fuel stove to propan couldn't be easier! Just buy a converter on-line or at your local outdoor/sporting goods store. Prices range from $13.00 - $25.00 (online w/shipping). The Century converter is USA made and very high quality (less expensive examples are imported). Screw on a disposable bottle, insert the end of the converter into the generator receiving hole inside the stove, crack open the regulator valve about 1/4 turn or so, and put a match to the main burner. Burns clean and hot. My Century-equipped stove works great!
