3/8 inch NPT female on the bottom of the unit (that is you have to hook it up to a male). In other words its not flare, so you will have to use pipe dope on that end. I got a 1/2 inch flare connector line that came with a bunch of adapters, so that did the trick.

I got: mounting bracket (not the legs, those are sold separately), and some screws and spacers for wall mounting. You also get 1 AAA battery for the starter. You will have to buy your own connecting hose and any adapters/valves to get it into your gas line. Uses 3/8 NPT female (must connect to a male).

Good heater, good price
Really puts out the heat! It does make a rather noticeable hissing sound, when on high, medium, or low. But it does the job, very well. Shipped to my home incredibly fast!
