Flow Never Becomes Ready
Troubleshooting
If the gas flow never becomes ready, check for the following:
• Check the supply gas for sufficient delivery pressure.
• Check the configured gas type. The configured gas type
must match the actual gas plumbed to the GC.
• Check for leaks in the gas delivery plumbing and the GC.
(See "Checking for Leaks".)
