Propane gas line

csctex Member Posts: 1
Installing propane gas range and oven. Probably 16000 to 20000 btu. What size gas line do I need. 25 feet approximately

    1/2" black steel will do fine.

    The LP Gas company would use 1/2" OD Copper. I prefer the Black Steel Pipe, But if you need custom cut pipe lengths, and don't have a threader or Mega-Press, You can use the K-copper or L-copper. Stay away from M-Copper for LP gas

    Also use the thick wall forged Flare nuts.

    Stay away from The thin wall Flare nuts usually found at big box stores
    And make sure the copper tubing is properly reamed and prepared before you flare the tubing.

    After you make that expensive repair and you still have the same problem, What will you check next?

    seems like awfully low btu's for a full propane range with oven

    Yes, a typical slide in gas range is 60,000 btu/hr. 

    I'd use 1/2" soft copper.

    propane line is also dependent on where it is going to be run and if its going to get closed in after.

    Put it in before gas stoves are outlawed.

    Do you have a 2 stage regulator in the system?

    Home Depot will cut and thread the black iron pipe for free if you buy their pipe.
