Gas line. Flare joint consealed?

[Plumber69]

Can a gas flare joint be consealed after testing for leaks?

In general, fittings that have been specifically listed for such use could likely be used. However, most codes I've seen prohibit
"tubing fittings" in concealed areas. As a matter of fact, a flare joint implies the use of copper or aluminum tubing,
which few jurisdictions allow for gas piping at all (as opposed to being an original part of a listed gas appliance). The flare connections at each end of a flexible appliance connector cannot be concealed, nor can any part of the connector be concealed, as in running thru a wall.

So: no.

Why is there a flare joint in the wall in the first place. It would only happen normally if the entire gas system is soft copper.

It's actually under a deck soffit. Running a line to a bbq. But only way to make connection is a flare joint

Normally, you would extend the steel pipe through the surface and THEN convert to the flare joint.
