I don't like the idea of loosening the fittings, mostly because I used to plumb hydrogen lines, and I hate what a small gas leak can do in tight spaces.
It does take a long time for those lines to clear. The person who said that the gas is heavier than the air and will eventually fill the line is my hero. That's exactly what I wanted to hear.
I'm glad to hear an expert on gas lines is also reluctant to mess too much with those connections. I had an experience here at home with a built-in BBQ grill that has made me understand that not everything "just needs to be tight."
