Lochinvar & A.O. Smith 100274734 Flue Sensor
The Lochinvar & A.O. Smith 100274734 Flue Sensor is a critical safety component designed for high-efficiency condensing boilers and water heaters. This exhaust temperature sensor monitors the heat levels within the venting system to prevent heat exchanger damage and plastic vent meltdown. Also identified by part number TST2013, this NTC thermistor provides the control board with precise resistance readings, ensuring the unit modulates or shuts down if flue gas temperatures exceed safe operating limits. Engineered for compatibility with Lochinvar Knight and A.O. Smith Cyclone series, this OEM replacement flue sensor ensures system reliability and prevents nuisance lockouts caused by inaccurate thermal feedback. Integrating this condensing boiler sensor during routine maintenance helps maintain peak thermal efficiency and protects the secondary heat exchanger from excessive thermal stress.
Technical Specifications and Benefits:- Precision Thermal Monitoring: High-accuracy NTC thermistor provides real-time data to the integrated control system.
- Broad OEM Compatibility: Verified for use in Lochinvar, A.O. Smith, State, and American Water Heater commercial units.
- System Protection: Triggers immediate safety protocols if exhaust temperatures reach levels that could compromise PVC, CPVC, or PP venting.
- Direct Fit Installation: Standard threaded or plug-in design allows for rapid field replacement and minimal downtime.
What are the symptoms of a failing 100274734 flue sensor?
Failure typically results in "High Flue Temp" or "Flue Sensor Open/Short" error codes. Technicians should check the resistance values against the manufacturer's temperature-resistance chart before replacing.
Can this sensor be used in both natural gas and propane configurations?
Yes, the 100274734 sensor is designed to monitor exhaust gases regardless of the fuel type used in the combustion process.
How does this part prevent heat exchanger failure?
By detecting excessive flue gas temperatures, it indicates potential scaling or soot buildup on the heat exchanger surfaces, allowing for intervention before catastrophic damage occurs.
