CSST in a wall?

[oxmanwi]

Can you put CSST in a wall through wood studs? As long as you have nail plates.

For safety purposes? Yes. Per code? Check with your local Big Brother.

Make sure you ground CSST whenever you use it.

I ran a portion of pipe through an oversized iron pipe.

Might be a dumb question. But what is CSST?

Corrugated stainless steel tubing (For gas piping).


Just looked it up on Google and learned something.

I love the net.

Ground the first fitting. Use all of the appropriate nail plates etc. they also have a termination piece for exiting the wall.

Ground the first fitting.

Actually, you need to jumper across the pipe itself to the first fitting on the rigid pipe. CSST fitting are/can be dielectric. In other words, the CSST is isolated from the piping and creates a gap in electrolysis. You need a clamp on the CSST fitting to a clamp on the rigid pipe in order to maintain ground continuity.

That's an interesting diagram IMO.

Usually, that final connection between black pipe is a CSST appliance connector. At least here, bonding is not required nor suggested for an appliance connector.

I have all copper LP line, except a new CSST that goes up to the attic for a new furnace. I wonder if it should have a jumper around it according to code?
