Nice Boiler!
This boiler is small, but of very good quality. It comes ready to run with tubing, a gas tank, and condenser. I bought it the optional gas regulator, which automatically adjust gas flow to the burner according to steam pressure. Unfortunately, there was no documentation included. So I had to guess the steam outlet thread size, which I believe to be 9/32x32. So, if you plan to solder custom piping, keep that in mind. Also, the burner and steam outlet fittings are glued to the boiler, so they cannot be unscrewed, which I find very unfortunate, should there be any maintenance required.
