The Flue Temperature Sensor on Your Rinnai Boiler

The flue (exhaust) temperature sensor watches the temperature of gases leaving the boiler. Abnormal readings indicate a blocked or failing heat exchanger, scaling, or venting issues, and will trigger a protective shut-down.

On Rinnai systems — including models such as i-Series i090, i120, M-Series — a failing flue temperature sensor often shows up as error 11 no ignition or related symptoms. We diagnose it precisely and install the correct genuine Rinnai part.
