What should be done before connecting a regulator to a fuel gas valve?

Cleaning off dirt before connecting a regulator to a fuel gas valve is crucial because any debris or contaminants present can interfere with the proper functioning of the regulator and the entire gas delivery system. Dirt can block gas flow, create pressure inconsistencies, or even damage the regulator's internal components. This step ensures that the connection is as secure and reliable as possible, minimizing the risk of leaks and ensuring safe operation.

While inspecting for leaks, testing for pressure, and checking alignment are also important considerations, they are typically performed after the connection is made. Ensuring the area is clean before making any connections lays the groundwork for a safe and efficient installation. It helps to avoid potential hazards associated with gas leaks and ensures that the regulation of gas flow will function correctly from the start. Therefore, establishing a dirt-free interface is a fundamental first step in the process.
