Gas leak check and purge before ignition is all about safety. Purging clears out any accumulated flammable gas from the fuel lines and surrounding spaces so there isn’t a hidden pocket of gas that could ignite when the system is started. It also gives a chance to detect a leak before ignition—if gas is present, a detected leak can be fixed rather than risking a release at ignition. This isn’t about increasing fuel pressure, sterilizing lines, or calibrating sensors; it’s about removing gas to lower ignition risk and ensuring any leaks are found beforehand.
