The OEM Pentair stack flue sensor (SFS), which shuts down the heater if the flue gas temperature reaches 480¡ F (249¡ C). The Stack Flue Sensor is designed to regulate the flue gas output, ensuring it does not exceed 500 degrees Fahrenheit. It is capable of operating in temperatures ranging from -20¡C to 105¡C. Additionally, it can resolve common error codes such as E-02, E-05, and E-06. The Stack Flue Sensor functions to limit the flue gas output to a maximum of 500 degrees Fahrenheit. It can operate within a temperature range of -20¡C to 105¡C and can resolve common error codes such as E-02, E-05, and E-06.

• Automatic Shutdown Feature:ÊThe SFS protects the heater by shutting it down when flue gas temperatures reach 480¡ F, preventing overheating.
• Temperature Regulation:ÊIt is engineered to control the flue gas output, keeping it safely below 500 degrees Fahrenheit for optimal operation.
• Wide Operating Range:ÊCapable of functioning in extreme temperatures, from as low as -20¡C to as high as 105¡C, the sensor offers versatile application.
• Error Code Resolution:ÊThe device is not just a safety measure; it also troubleshoots common error codes (E-02, E-05, E-06), ensuring continuous heater performance.
