I ran the heater for about an hour, probably on about 65%. Then let it cool and rechecked the areas where my electronic sniffer alarmed. Re-checked it this morning with no alarming either time. I also closed the tank valve overnight and the regulator still showed green this morning indicating pressure in the system.
I had considered one option as a piece of "dirt" in the shut off solenoid valve seat area, holding the valve partially open. This appears to be the issue since the leak has ended (most leaks do not cure themselves) and when I disassembled the threaded connection at the inlet to the heater, there was some powder like substance in the area of the cone sealing area.
I will have to watch this to see if there is more dirt somewhere in the system, or if the leak returns.
What's curious is the factory area gas sniffer did not alarm, my wife's nose identified the smell, but, I did not. I'm glad H2S is added to the gas.
