@R. Anderson:
So before I get to redoing pipe sizes, you ran 2 psi in 3/8" at 120'? So since the 3/8" is only a portion (in the middle of my whole run), as long as I get 2psi the entire run (with of 1/2", 3/8", back to 1/2") then with regulator at 60k BTU I should be good? Please clarify as I am...
