You may have had a power failure. The situation could be as simple as turning the stove off and on again. The 12 code means flame failure. Gas heater are nothing to mess around with if you don't understand them completely. Don't remove anything from the unit unless you are very sure what you're doing. A call to Rinnai is in order if the code keeps coming on. Good luck,
