prior to start-up. Open the safety valve to allow air in the tank to escape.
3 Be sure all connections into the tank are tight, as leaks at tank fittings will damage the insulation.
4 CAUTION: Conduct the following gas train leakage test before start-up, at annual intervals and prior to
investigating the cause of any reported occurrences of delayed ignition.
a. Using an appropriate bubble detection solution, thoroughly coat all gas train pipe connections. If any
bubbles are detected, the leaking connection must be tightened, recoated, and rechecked to assure
stoppage of the leak.
