Well, Occam's Razor for the win. There was a previously unknown gas valve way over by the gas meter that somehow got turned off at some point in the last 5 months. I've put everything back the way it was including the original Fenwal and it fired right up!

Thanks to @ajw22 @setsailsoon @swamprat69 for the guidance. I certainly know a lot more than I did a few days ago about the heater and effective troubleshooting.

I hope this thread helps someone else in the future.
