When gas piping is concealed in a wall, what is required?

When gas piping is concealed in a wall, the requirement is to have a direct access panel. This access panel is necessary so that maintenance and inspections can be performed on the piping without cutting into the wall. It ensures that any potential leaks or issues can be addressed promptly and safely without compromising the integrity of the structure.

In addition to allowing for easy access, the panel ensures compliance with safety regulations and standards that govern gas installations. Concealing gas piping without an access point could lead to significant safety hazards, as it may prevent timely detection of leaks or mechanical failures.

While shut-off valves, venting systems, and tee fittings are important components in gas piping systems, they do not address the specific requirement for concealed piping in terms of access for maintenance. Thus, the direct access panel stands out as the crucial element when gas piping is hidden behind walls.
