It runs on a 20lb propane tank. You can take off 3 "doors" out of 4 so if the wind is blowing the flame won't go out. Has an adjustable flame and gets pretty hot. The igniter wasn't working but it can be lit manually. May be clogged or just need to be replaced. Either way I couldn't pass it up for such a cheap price. I was 1/2 hour away shopping with the wife and boy when it popped up on CL. Emailed and said if he gets back to me before I head toward home I'd come pick it up. Luckily he got back to me right away so off we went. It's very well built, sturdy as hell. Weighs a ton too.
