Title: LP Black Pipe Run
Post by: Gerry H on July 03, 2014, 08:15:26 PM
I need to run my stove LP black 1/2" pipe through my middle bay which has all my electrical. Main 50A breaker box, sub breaker box, every thing is in EMT conduit, but I was wondering if there is any code or common sense issues with running the pipe thru that area of my middle bay. Will probably put a gas alarm in both bay areas. LP tanks are in front bay driver's side, no electrical in that bay. What say you code talkers? Thanks Gerry H

NFPA 54 (Fuel Gas Code) Section 2.7.2(c) requires that gas meters be located 3' from sources of ignition.  The NEC (National Electrical Code) does not specify any clearance requirements as long as the working clearances in section 110 are met.  I can send you a PDF of section 110 if you need it.

The NFPA and NEC are minimum requirements for a safe install.  You can build above and beyond the minimum requirements.

    I have no idea of code but I would think that if you have a single piece of black pipe that's properly attached at the front end with the tanks, running through your electrical service area with no joins or valves, and then properly secured and attached at the other end, there wouldn't be any problem with that.  I'd also be careful that any other item (wires, structural members, water pipes, etc.) are properly isolated and secured to the working clearances in the code so that they can't damage the black pipe.
    All this is just "common sense" from me but it seems to fit in with SPlug's post, showing that the code isn't very exhaustive.  If anyone has more information, I'd be glad to hear it.   Bruce H    coastal NC   USA

Hi Gerry, after your pipe is run and secured in place, paint a bright line across every coupled or elbow joint in a straight line about 2 inches, if for some reason the pipe rotates or elbow moves, besides smelling a leak, you could see immediately that a joint has moved, lvmci...

Gerry check on FMCA site and see if they use to have a download of the RV code and thats where it would be. Each state also has it supplemental code that you might want to check. If you use gas pipe sealant tape ( which is yellow) or the tube paste on all ends before putting each together and make sure they are good and tight and use Tom suggestion.
If you have the metal pipe touching any metal or going through a wall or bulkhead etc, wrap it with rubber and secure with a strap over the rubber.
It is pretty tough in an RV to get all wires away from it so just make sure all the wire ends that are close to any joints are in a boxes.

I used 1 short run in our bus and then came off that with 3/8" soft bendable copper. Rubber hose from the tanks to the black pipe.

RV's with propane fall under the Federal Motor Vehicle Safety Standard  NFPA 1192 about the only thing said is use black pipe, no more than 12 inches of copper,make joints assessable ,label  and run where a nail cannot pierce it like that would happen on sch 40 steel pipe

 It also needs to be printed on Bay door that it can be turned off by Firefighter's through "LPG" and left unlock while traveling.
