The K16RA-36 thermocouple is engineered for high-ambient temperatures

Its bimetal disc sensor provides high-accuracy temperature sensing and rapid response times

The GN series utilizes updated materials for better thermal resistance and longevity compared to the discontinued GF series while maintaining identical mounting dimensions

it uses standard 230V wiring configurations familiar to service contractors

Lochinvar & A.O. Smith 100112678 Flame Sensor 323613-751 The K16RA-36 thermocouple is engineeredThe Lochinvar & A. O. Smith 100112678 Flame Sensor is a critical OEM safety component engineered for precise flame rectification in high efficiency boilers and water heaters. Designed for Lochinvar Knight and A. O. Smith B4940, B5930, B5940, and B7930 series units, this sensor monitors the burner's ionized path to ensure the gas valve remains energized only when a stable flame is present. Constructed with a high grade Kanthal or equivalent alloy rod
