Propane piping for garage heater

[fairlaniac]

I'm using the 1/2" yellow poly coated copper tubing from my Rexnor heater to a 100# bottle outside. It's all one piece through the wall but I need to decide how to finish it. I currently brought it outside and up high with about 15 ft. sticking out. I have seen where people do a large loop in the copper as they bend it towards the tank. I have also seen people use a 90 degree fitting. Right now my tank is directly 10 ft. below where my line comes out. Other than less joints to leak, which is the better choice?

thanks,

I usually see iron pipe through the wall ...then a transition to copper... maybe you could sleeve pipe where it goes thru wall.
I piped mine with a "loop" coming off regulator...i left it as more of a big "u" ...thinking as a just in case tank moves or settles abit

Ayuh,.... So what's yer question,..??

If the regulator is mounted to the wall, it just needs the line hooked to it,....
The pigtail allows for movement to change the tank,...

If the regulator is "in-line" attached only to the line, 'n tank,...
Yes, ya need a loop or droop to allow movement to change the tank,....

I ran an iron pipe from the regulator, up the outside wall, then into the garage.

It works, but I think the correct way to do it is to minimize the outdoor run after the regulator, ie poke the line into the building with only a couple of feet exposed to the elements to prevent pressure loss in cold weather.
