Which of the following is NOT a requirement for the locations and installation of gas outlets?

Shall not be located behind doors
Must extend at least 3 inches above the surface of floors
Shall not exceed 1 inch unthreaded through walls or ceilings
Outlet fittings must be securely fastened in place

The correct answer is: Must extend at least 3 inches above the surface of floors

The correct answer points to a requirement that is not standard for the installation of gas outlets. Specifically, the guideline about the height of a gas outlet needing to extend at least 3 inches above the surface of floors is not universally mandated in gas fitting regulations. In actual practice, the primary concerns for gas outlet installations involve safety and accessibility. Proper location includes ensuring outlets are not obstructed by doors, to avoid accidental disconnection or damage. The requirement regarding outlet fittings being securely fastened ensures that connections are stable and reduces the risk of gas leaks, thereby promoting safety. Additionally, guidelines regarding the threading of outlets through walls or ceilings relate to ensuring a secure and leak-free installation. By understanding the rationale behind each installation guideline, it's evident that the elevation requirement stated is not a recognized stipulation in the common regulations for gas outlet installations.
