Gas valve leak in pilot position?

[PLohr]

Working on a new Napolean GDI-30P (propane). The unit has never been used and has been sitting for about 6 years. The gas line needs bled so I am pressing the pilot light knob in with the knob in the "pilot" position. What doesn't seem right is the air being bled out of the gas line is exiting somewheres around the control valve (which is under the fire box) rather than at the pilot light. Almost as if the control valve has a leak. Does this make sense?

Thanks for your time.

Get your self a gas sniffer or use some bubbling compound. If there’s a leak, you’ll find out where it is…

I should have stated the question more clearly.

In any circumstance, is it normal for gas to exit at the control valve, rather than to exit through the pilot burner?

Loose or unsealed regulator head, loose gas pressure screw, loose gas fitting.

Finally figured this out. Maybe this will help someone else in the future.

Problem 1: Part of the LPG conversion kit had been installed incorrectly. This has an SIT 820 mv control valve. The Hi / Lo knob assembly, which is part of what is replaced during LPG conversion, was cocked and not sealing. Propane for the pilot passes through the bottom of that assembly so it was leaking out at that assembly.

Problem 2: Probably at the factory, the pilot tubing had been smashed closed in one place. As if the entire lower plate assembly had been dropped. Can't see how it would have happened otherwise.
