Flex gas line. Okay to use outdoors?

[coilerman]

I'm having a new heater installed and the gas connection for old and new heater do not line up. Are the flexible pipe options to connect from the riser to the heater? It would have to be rated for outdoor application.

I know my gas stove is connected using a steel corrugated pipe (flexible). Is this same line used in pool heater application?

I know where I live, the code does not allow flex line for outdoor heaters.
I think it's a regional thing, but I could be wrong.

In my area I can have flexible only underground then must be hard pipe above ground.

You'll need to check your state and local building codes. In Florida most counties refer to the 2017 Florida Building Code. It permits several different materials including corrugated stainless steel but there is a specific ASTM spec for each different pipe. Wrought iron is prohibited. Underground has its own set of requirements including a detection line and special requirements for the riser. If you can't find the requirements online I'd suggest you call your local building code office. They are surprisingly helpful in my area.

[B]coilerman[/B] - my neighbor has flex line for his heater. We are located in southern ont. so I assume it passed an inspection, but I would double check with local codes.
