Actually I'm more of a chevelle man. LOL, now you're saying everything changed right after you left Michigan? :please:

Finally, Act 733 establishes a licensed master plumber shall be in charge and responsible for proper installation and conformance with the code. The requirement of having a master plumber for supervision assigned to the contractor is implemented and stated in Sections 7(d), 9©, 15(1), 21(4), and 41(2). It's plumber work.

I don't see a date there. I was running med gas from 2001-2003, and I sent you a msg on the prerequisites(to keep it away from the thread) to run med gas at that time. There was no plumber requirement. You posted 2006 code, I was long gone by then. Like Hoot would say, good luck finding 2001 code.
