On a heat call, the control board energizes the igniter; it glows red-hot, and once it reaches temperature the gas valve opens and the burners light. Hot surface igniters are the most common no-heat failure point — the silicon carbide or silicon nitride element is brittle and degrades with every cycle. The bundled VR8205S valve provides the safe, sequenced gas flow that the HSI ignition system depends on. If the furnace clicks but never lights, the igniter rarely glows, or you see repeated lockouts, this kit restores reliable ignition.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eIgniter Part Number\u003c\/td\u003e\n\u003ctd\u003e1172533 (IGNITOR HSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGas Valve Part Number\u003c\/td\u003e\n\u003ctd\u003e1172821 (VR8205S HSI Snap)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar \/ ICP \/ Heil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIgnition System\u003c\/td\u003e\n\u003ctd\u003eHSI (Hot Surface)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGas Valve Model\u003c\/td\u003e\n\u003ctd\u003eHoneywell VR8205S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDesigned for the Tempstar T8DNL075F16B1 furnace and the ICP\/Tempstar\/Heil T8DNL platform using hot surface ignition with a VR8205S snap-action gas valve.
