3.3.6 Perform Leak Test
After installing and tightening all gas connections, perform a leak test to ensure there are no gas leaks
anywhere in the system.
1) Pressurize gas supply lines to machine.
2) Close supply valve, unscrew regulator adjusting screws.
3) Watch regulator output gauge for pressure drop over time (at least 10 minutes).
4) If pressure drop is detected, apply soap solution to each gas connection until leak is found
and fix it.
