Awl -

I'm *doing some demo on my 50's kitchen, which was done pretty well,
overall -- 3/4 black pipe to a 6 burner stove, etc.
Except, they tee'd off underneath for the gas line to the oven, using 1/2 or
5/8" copper, flare fitting.

I've been told copper gets brittle with natural gas, and is therefore
against many codes. *Is this accurate? *Is this a recent discovery? *Seems
odd that the original installers would use 3/4" black pipe, and then wimp
out at the end.

Are there similar restrictions with copper and propane? *Other gases?
If this restriction is only with nat gas, I assume it's because of the
sulfer additive (smell) that reacts with the copper.

Call your natural gas supplier. I got a lot of good info when I added
a concrete porch onto the back of my house. The project interfered
with the planned installation of a gas line to a fireplace that was
surround on three sides by the patio. BTW the last few feet of my
fireplace installation is with soft Cu tubing, so is my gas water
heater and furnace . The installation was done by the gas Co so I am
assuming it is OK for short terminating lengths. The opinion of your
gas Co may be different.
