Jeff, I might be making a noob mistake and calling it the wrong thing. When I said purging, I meant the very low pressure gas I use as I am brazing to keep the black soot stuff from forming on the inside of the pipe.
I know purging is also the process of running a higher pressure gas (like nitrogen) through the system to clean out any particles.
Sorry if there was confusion or I am just totally wrong on every point. lol
I was looking at this though

Thanks man! I should have it up and running next week, I still have to finish the electric fence around the hard red winter wheat I just planted, and put the wood stove back together. WINTER IS ALMOST HERE!
