Here is my gas hook ups
1st picture is just gas line from tank to hard piping
2nd & 3rd pictures are a view of the back side of the valves. They are the same kind you would find in a chem lab to use on a bunsen burner
4th picture is my burner. I used the cut out from the top of the keg as a heat shield and it works great. As you can see the propane tank is underneath the burner and it does't even get warm to the touch
The last picture is of my keg supports. I welded them out of old bed frames and made little tabs that support it of the wood frame. The heat transfer is minimal and the wood barely gets warm. Also, the wood surrounding the burner does get a little warm but not above what is comfortable to touch. I was concerned a little before I first used it, but it has worked out well. Plus I don't leave it alone when I am brewing.
By the way, I can't figure out how to write captions between the pictures so I have to list everything in the beginning. Any help?
