Flex SS gas lines

[barlyhop]

I see quite a few flexible stainless steel gas lines connecting appliances and water heaters. Is 5 foot the rule of thumb for max length? Are there exceptions to that? I also see them go through the subfloor upstairs to gas fireplaces. Thought that this wasn't allowed either?

Any thoughts?

6' is max for ranges and dryers. That does not mean two 3' sections hooked together.

Furnaces, water heaters, cooktops, etc. are limited to 3'.

And no the flex is not supposed to pass through floors, walls, ceilings, etc..

Are you talking about corrugated stainless steel tubing or an appliance connector?

The corrugated yellow flex piping. Why are these long lengths sold at Home Improvement stores?????

Thanks

Randy,

I think you mean CSST. Right? With this bunch, you should be more specific with the question.

Because, aside from being yellow, CSST and appliance connectors are two completely different things.

CSST is allowed to pass through floors and walls.

One important thing to check for whenever you see CSST in a house is that the gas piping should be bonded to the grounding system of the house.

At some point the CSST is connected to rigid steel gas piping. Check those rigid areas of piping. If you cant find a copper bonding wire of at least #6, call it out.
