| can anyone help me find the proper code or regulation for running natural gas out doors. when my house was built they put a natural gas valve out side on the deck. I'm planning on getting a ng weber in the next week or so . i will need to run a gas line under the deck about 12 ft. then down roughly 4ft where i will make a box mounted to the support with the quick disconnect and another shut off valve. Any ideas what i should use to run the line. Painted black pipe, csst, or some sort of poly. what is code im having issues finding anything saying what it is. Thanks in advance |

That's a tough one. I know the regular plumbing codes for WI don't address gas lines, cause I went through them for my remodel project.
Do you have a local inspector who you can ask these questions of? I know my local guy was pretty easygoing, and I was able to ask some pretty dumbass questions sometimes. :) ETA: Try this link. I think you might want to look into chapters 20-25. codes |

Alot of people use sch 40 "black" steel pipe like Home Depot, etc carries. It must be wrapped with an appropriate material if it is run under ground.
If you comply with NFPA 54 (National Fire Protection Association) (National Fuel Gas Code) , I would expect that you should be in compliance with any WI Code..... No cast iron allowed. Schedule 40 standard weight seamless steel pipe
complying with ANSI B36.10, ASTM A53 or ASTM A106. http://www.minhbao.com.vn/userfiles/file/A_NFPA54.pdf |

Do not run it in black pipe
I have done it in two ways: SDR11 polyethylene pipe, trace it with wire so you can detect it later, and a gas riser at each end. Hard or soft copper and if you are concerned about hitting it with a digger, sleeve it in PVC. This falls under national fuel gas code. PM or email and I can try to help. |

I guess I wasn't that clear. The deck is elevated about 5ft above ground so when I said I'm running it under the deck it will still be roughly 4'6" off the ground. Is corrigated stainless steel tubing alowed out side above ground. I don't have a source or the tools to install the poly stuff. Looks like they just used black pipe on the gas meter then painted it silver. Also I was wrong on the size the stub out is 3/8. Its only going to be about at 15 foot run. and I don't know if it matters but the grill is rated at 38,000btu Posted Via AR15.Com Mobile |

Quoted:
1/2" black pipe is the right way to do it. My opinion is corrugated stainless is more trouble than its worth unless you have to fish it through an attic or the like. ok sounds good , now i just need to measure and find someone to cut and thread a 11ft pipe . |
| I would use black pipe or soft copper with flared fittings. Poly is not allowed above ground. Csst requires bonding from your electrical panel. The gas code is really open to interpretation by your gas supplier. They change what they accept frequently and it varies on the gas tech. |

The 'silver' stuff you saw is what was put in by the gas company when they installed the meter. The only code regarding that sort of stuff is that the pipe that goes through the exterior wall of the house has to be painted.....thus the grey pipe.
The black pipe will rust, so if you see it at all, wash it down (to get the oil off) and paint it after installation. Make sure to put a drip leg at the bottom of your drop, so oild, moisture can collect. If getting pieces cut is too much of a pain, getting a 10' section, some couplings and different sized nipples (shorter sections of pipe are called nipples, usually in 1" increments from 1" to 12") and put it all together yourself. Make sure to use pipe 'dope' and crank tight. |

If he cnnects it to the existing system it should be grounded already. |

I will get the long piece cut. For the rest I have misc sced 40+80 fittings and a 1/2 nipple tray. I work with high pressure steam a lot so I know all about using dope and cranking the piss out of it haha. I'm thinkin I will put a drip leg where I drop below the deck and again where I drop down to the grill. Should be all good as long as I remember to blow them out every so often.
