Rinnai propane heater error code 11.
I have a rinnai hydronic furnace and tankless water heater 2 br home.
No flame in the combustion chamber gas installation with the gas regulator.
Check your hot water system for any visible damage or loose parts locate your gas supply and ensure it is turned on.
11 is no ignition and 12 is flame failure.

I dont think it s a flow issue.
Have a tech call them from on site and trouble shoot the unit.
Verify the proper flame rod wire is plugged into the proper flame rod.
A loose flame rod is called a floating flame rod and will result in code 11 s or 12 s.
This includes the following.
Code suggested prob with ignition.
Here is the summary of what can go wrong with your rinnai water heater and what to look for after the error code 11 shows up on the remote controller.
Verify the flame rod is tight in its mounting bracket.
Some units have multiple flame rods.
What does that mean.
Rinnai error code 11 is an indication that there is no ignition in or no gas supply to your hot water system.
It means that your water heater broke well obviously thanks to the heating system that is not working.
Perhaps because your ignition system is not working well.
A quick check to verify correct wiring is to look at the stamped letter on the bracket at flame rod sample a y indicates yellow r red and b blue.
