Question:

Is buried copper pipe in code for propane lines from the tank to my house, or should I change to black iron?

We have been told that we need to replace our buried copper pipe from our propane tank to our house with black iron pipe because buried copper is no longer in code. How do I find out what is right and what is wrong?

Answer:

these are all reasonable and they are concerned about your safety; however the tank will not freeze, do not run the copper into the fireplace box, use black 3/8 or 1/2. the copper will melt or distort in time with the intense heat but black won't, plus you install under the flame rather than above. use it as a fire starter assist or mood low-lite flame. the little tank is not meant for large flame fireplaces and will empty in short time. not cost effective! as for the underground, do 18 after leaving the tank to the outside of the FP, then up the wall to the exposed 1/2 black pipe and join w/ petcock. remember if you have a bush around the fireplace somewhere, you needn't bury the line, place the tank there and a short-run to the petcock. additionally, place in a spray btl a small amt of dish soap and equal amts of wtr. spray this on the lines joints for leaks and if it bubbles.fix it. you're not afraid to cook on your BBQ and the flames on the top and the tank does not explode. so don't worry, this is done all the time and you have a layer of bricks and mortar between the tank and the flame. furthermore, use a carbide drill the size of the pipe to drill into the brick wall then seal with a seal recommended for your area. do a small pilot hole 1st like 1/4 then follow with 1/2 to fit.
Unless the code has changed lately this is incorrect. Copper is not approved by code for natural gas and has not been for several years. LP gas however as far as I know of is still approved to be used in copper. The size of the line from tank to home may be too small but that can be rectified with a second stage regulator at the home and run 10 pounds pressure from tank to house regulator inlet. Maybe someone wants your copper line for junk. A lot of copper theft around here. And then again maybe someone has just jumped the gun. Ask some local LP gas retailers. They wont mislead you and will give it to you straight. Now I'm speaking of the National fuel gas code. If your state has outlawed copper Id like to know and if you can find out, why.

I really think you have been told wrong. The iron pipe would have to be coated. Copper doesn't need to be. Maybe in your area. LP has a sulfur content, but very inlikely. Call your local LP supplier. They will know
thats not a good one as all it will do is suck hot air from the engine compartment, just buy yourself a KN air filter that fits in your stock airbox and you will get better results.
