The genuine OEM Pentair Stack Flue Sensor (SFS) 42002-0024S acts as a vital safety mechanism that triggers an automatic heater shutdown once flue gas temperatures hit 480° F (249° C). Designed to cap flue gas output at a maximum of 500 degrees Fahrenheit, this sensor guards against dangerous overheating conditions. It maintains full functionality across an ambient temperature span of -20°C to 105°C, making it suitable for diverse climate installations. Beyond thermal protection, this sensor also addresses and clears common diagnostic trouble codes including E-02, E-05, and E-06, helping restore normal heater operation when these faults arise.

Key Benefits

• Auto-Shutdown Safety: Activates an immediate heater shutdown when flue gas temperatures climb to 480° F, serving as a critical line of defense against thermal runaway.
• Flue Gas Output Control: Precisely limits exhaust temperatures to stay below the 500 degree Fahrenheit ceiling, keeping heater operation within safe boundaries.
• Extreme Climate Versatility: Rated for ambient conditions from -20°C up to 105°C, this sensor performs reliably in both frigid and scorching environments.
• Diagnostic Code Resolution: Goes beyond simple temperature monitoring by clearing error codes E-02, E-05, and E-06, restoring heater functionality and reducing service call frequency.
