Understanding Code 11 Of Rinnai Tankless Water Heater

Your Rinnai tankless water heater employs a system of error codes to indicate when things are not right, and one of the most common issues homeowners face is the infamous Error Code 11. Typically, this code implies an issue with the ignition, meaning the heater is not starting as it should.
