SMITH 100108267 is a thermocouple kit designed for use in gas-fired heating appliances. It generates a 30-millivolt (mV) output signal that holds the gas valve open when the pilot flame is proven, providing a critical safety shutoff if the pilot goes out. The kit is identified by model designation TC-K24 and measures up to 24 inches in length, making it suited for installations where a longer lead is required between the pilot burner assembly and the gas valve. Licensed plumbers and HVAC technicians are the typical installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis thermocouple kit is intended for residential and light-commercial heating applications, including gas water heaters, boilers, and furnaces that use a standing pilot ignition system. The 24-inch length accommodates a range of equipment configurations where the pilot assembly sits at a distance from the main gas valve. Always verify the thread type and tip configuration against the existing equipment before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30 mV output compatible with standard millivolt gas valve circuits\u003c\/li\u003e\n  \u003cli\u003eUp to 24 inches in length for flexible routing in tight installations\u003c\/li\u003e\n  \u003cli\u003eStanding pilot safety shutoff function — gas valve closes automatically on pilot loss\u003c\/li\u003e\n  \u003cli\u003eTC-K24 kit format includes hardware needed for a complete replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement thermocouple kit for gas-fired heating appliances equipped with standing pilot ignition systems and standard millivolt gas valves.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician in accordance with the appliance manufacturer instructions and applicable local codes. Shut off the gas supply and allow the appliance to cool completely before removing the existing thermocouple. Hand-tighten the thermocouple nut at the gas valve first, then snug with a wrench — avoid overtightening, which can damage the fitting. After installation, verify pilot flame engulfment of the thermocouple tip and confirm proper gas valve hold-in before returning the appliance to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e: TC-K24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Voltage\u003c\/strong\u003e: 30 mV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Heating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: A.O.
