Question about Air Conditioners
Most all regulators require a differential in pressure to work. To get a differential, you need to have gas pressure on one side of the diaphragm and atmosphere pressure on the other side. If you have high moisture, you can either effect the differential pressure, cause a freezing condition in the regulator in cooler weather or subject the regulator to premature failure due to corrosion. You did not explain if this is going to be used in a high moisture area or not. Can the regulator be vented to a low moisture area?

Check that the gas is turned on at the water heater and gas meter. Check for obstructions in
the flue outlet.
Ensure gas line, meter, and/or regulator is sized properly.
Ensure gas type and pressure is correct.
Bleed all air from gas lines.
Ensure proper Rinnai venting material was installed.
Ensure condensation collar was installed properly.
Ensure vent length is within limits.
Verify dip switches are set properly.
Ensure appliance is properly grounded.
Disconnect EZConnect™ or MSA controls to isolate the problem.
Check power supply for loose connections.
Check power supply for proper voltage and voltage drops.
Ensure flame rod wire is connected.
Check flame rod for carbon build-up.
Disconnect and reconnect all wiring harnesses on unit and PC board.
Check for DC shorts at components.
Check gas solenoid valves for open or short circuits.
Remove burner plate and inspect burner surface for condensation or debris.
The above is what #12 indicates.
No way to fix it without further hands on investigation. I seriously recommend you call a licensed plumber.
Let me know,if needed further assistance.
