Why is leak testing important during installation?

Leak testing is crucial during installation primarily to ensure the integrity of the system and prevent accidents. This process identifies any potential leaks in the piping, connections, and appliances. Gas leaks can lead to serious safety hazards such as explosions or fires, as well as health risks from the inhalation of propane gas. By conducting thorough leak tests, installers can verify that all components are functioning correctly and that the system is sealed, thus maintaining safety standards and regulatory compliance.

The emphasis on preventing accidents speaks to the critical nature of handling flammable gases like propane. It is not just about confirming installation completion; rather, it involves ensuring that the system operates safely as intended. While the other options touch on different aspects of the installation process—such as pinpointing location or confirming pressure settings—none address the essential safety focus of leak testing.
