What is typically required regarding the pressure regulator in gas installations?

In gas installations, the presence of a pressure regulator is essential for controlling the gas pressure supplied to appliances, ensuring they operate efficiently and safely. This component is critical in managing the pressure drop from the high-pressure gas supply to a lower, usable pressure that can be handled by household or industrial appliances.

The requirement that a regulator must be present when no service regulator is used underscores its role in maintaining proper pressure levels throughout the gas system. Without a pressure regulator, appliances may receive gas at unsafe levels, which can lead to inefficiencies or even dangerous situations such as leaks or explosions.

While adjustability and digital formats can add versatility and precision to a pressure regulator, they are not foundational requirements for all installations. The essential function is that a regulator must be in place when the system lacks a separate service regulator to ensure that gas pressure remains within safe operational limits.
