To do it yourself...
all you need is to buy a cheap ( $20 coleman/white stag) propane burner. dismantle the force 10 kerosene burner fitting, and attach the propane burner through the same hole.You will need to drill a small hole for the control knob in the front of the unit. My kerosene was too smelly & sooty, plus the pressure fuel tank began to leak from corrosion. Mind you, you will not have the safety features that come standard with the off the shelf Force 10 propane unit. I believe it has a temp controlled shutoff valve and a low oxygen shutoff valve. So be aware of the potential dangers involved in doing your own refit! With that said, my converted unit works great with one exception that I believe to what led me to conversion in the first place. The exhaust flue is too small for the job & you will get exhaust gasses in the cabin. But at least they aren't smelly & sooty!The unit sems to put out more heat as well. I purchased a battery powered fan to circulate the air around the unit & am going to try it out this weekend. Good Luck!
