According to the Rinnai manual which is here:

It looks like that is a "flame failure". They suggest ventilating the room and turning the heater off and on again, I think this might mean the heater was eating all of the oxygen in your room.

Maybe cracking a window a small bit?

Rinnai heater flashes code 12


Next time you try your stove watch the flame. If the flame goes away and then the error code comes on, you have something wrong with the over temp circuit, gas or gas valve, If the code comes on and then the flame goes away you have a flame sensor problem.

Good luck,
