Description
The Utica-Dunkirk 240008227 is a factory OEM 1/4″ flue sensor designed as a direct replacement for compatible Utica-Dunkirk boiler systems. Utilizing a 12K NTC (Negative Temperature Coefficient) thermistor element, this sensor provides precise, real-time flue temperature monitoring to ensure your boiler’s control system operates safely and efficiently.
How It Works
NTC thermistors decrease in electrical resistance as temperature rises, allowing the boiler control board to accurately read flue gas temperatures at all times. This continuous feedback helps the system optimize combustion efficiency, protect against overheating, and trigger safety shutdowns when abnormal flue temperatures are detected.
Key Features
- OEM Utica-Dunkirk replacement flue sensor — ensures compatibility and reliable performance
- 12K NTC thermistor technology — delivers accurate, responsive temperature measurement
- 1/4″ probe diameter — designed for straightforward installation into standard flue sensor ports
- Monitors flue gas temperature for safe and efficient boiler operation
- Supports proper control board communication and safety lockout functions
- Genuine OEM part — maintains original equipment warranty and performance standards
Application
This sensor is intended for use in Utica-Dunkirk residential and light commercial boilers where flue temperature monitoring is required by the integrated control system. Always consult your boiler’s service manual or parts list to confirm compatibility before installation.
Why Choose OEM?
Using a genuine Utica-Dunkirk replacement part ensures the sensor meets the exact electrical and mechanical specifications of your original equipment. Aftermarket substitutes may not match the required resistance curve, leading to inaccurate readings or nuisance lockouts. Trust OEM quality to keep your system running at peak performance.
