Lochinvar & A.O. Smith 100108268 24" Thermocouple

The Lochinvar & A.O. Smith 100108268 24" Thermocouple is a flame-sensing control that generates an electrical signal when exposed to a burner flame, communicating with the connected gas control assembly. Its sensing tip responds to heat at the combustion area while the extended lead provides the necessary distance between the detection point and the control connection. The assembly fits near burner sections where flame verification is required during heating operation. HVAC systems use thermocouple technology within gas-fired equipment where combustion monitoring is essential. Its length matches compatible installations, supporting proper flame detection throughout normal heating activity.
