Propane and copper...........Yes
Natural gas and copper......No


I worked with a tech for a while that had done HVAC work in SE Minnesota. He
was telling me that some cities he worked in allowed copper for natural gas.
To the point that it was common practice to run hard copper and bazed
fittings, burried in the wall!
Seemed pretty crazy to me, but he assured me it passed code in that area!
