Question about Rinnai R75LSi Interior 7.5 GPM Natural Gas 84% Tankless Water Heater
Have covered everything in service manual, checked all wiring, new gas valve, fan, and flo servo. worked fine for 2 months, now code present again.
Absolute best solution for Tankless water heater is to replace whole thing with tank-type water heater and quit spending money fixing an old computer with multiple sensors that is connected to your water pipes, electric line, and gas line, that is connected to a gas burner with vent pipe to outdoors ... As if each of these systems doesn't have a load of problems on its own without a computer chip.
Otherwise, I do not have a source of information that is better than a service manual.
