Black iron steel gas pipe in walls for propane?
by admin on Tuesday, September 21st, 2010 | 5 Comments
I’m building a small camp in Maine and I want to run a gas line for a propane stove and water heater. I have a tank and regulator outside the house but will need to run the pipe about 20 feet in a framed wall to get to where the stove is. is it acceptable to run black pipe in a closed in framed wall? Is there a limit on the number of couplings and elbows that can be in a closed wall? I ‘m not planning on using any union joints but will probably need at least one coupling and a few elbows. I think this will cost me a lot less than trac pipe if it’s allowed.
I don’t know about in Maine but it is done quite often in the Eastern part of the United States. But something that is becoming more popular is Stainless Steel Flexible hose with a urethane sleeve around it. It is way easier to install and you can buy it in what ever length you need so all your connections are outside the wall.
Extra: For the ones who that gave me the thumbs down.

Corrugated stainless steel tubing (CSST). This material was approved for residential use in 1988 by the National Fuel Gas Code. It is an ingenious method of supplying natural gas to fireplaces, furnaces, cooktops, clothes dryers and any other gas appliance. Virtually all state and local code authorities permit its use and many contractors
are finally embracing it.

make sure you pressure test the joints for leaks before you close up the wall and it should be inspected. But there are no limits to fitting in the wall – except unions
Black pipe is the code, just minimize your fittings ASAP. Remember in the old days homes had gas lanterns and fixtures before electricity.
I’m not sure if code changes from place to place but I just had a shop built and I had gas pipe plumbed in for a furnace. The HVAC contractor ran black pipe from the ground to the attic in an exterior framed wall – and it passed the county building inspection.
black pipe is completely fine.
