Engineered for use with \u003cstrong\u003e1710 series valve bodies\u003c\/strong\u003e, this \u003cstrong\u003ethermomagnetic safety valve\u003c\/strong\u003e components acts as a fail-safe by automatically cutting gas flow upon pilot flame failure. Unlike the \"J\" series, the 1720-802 is a \u003cstrong\u003epilot outlet only\u003c\/strong\u003e configuration, making it the standard choice for specific \u003cstrong\u003eBJWA, FD, and GS series thermostats\u003c\/strong\u003e. This kit provides a complete field solution, featuring a \u003cstrong\u003e1\/8\" pipe tap\u003c\/strong\u003e head with included fittings for \u003cstrong\u003e3\/16\" and 1\/4\" compression tubing\u003c\/strong\u003e. This assembly ensures \u003cstrong\u003eflow interruption\u003c\/strong\u003e, preventing main burner gas release while the reset button is engaged. With an \u003cstrong\u003eambient temperature rating\u003c\/strong\u003e up to 300°F, it is built to endure the high-heat environments of \u003cstrong\u003ecommercial ovens\u003c\/strong\u003e and infrared heaters. Its \u003cstrong\u003ethermocouple-actuated\u003c\/strong\u003e magnet ensures millivolt-sensitive reliability, providing the precise safety shut-off required for professional-grade \u003cstrong\u003egas cooking controls\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits for Technicians:\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Engineered to integrate seamlessly with 1710 series valve bodies and high-demand \u003cstrong\u003egas safety valves\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete Installation Kit:\u003c\/strong\u003e Includes the \u003cstrong\u003emagnet head\u003c\/strong\u003e, diaphragm, valve spring, gasket, and high-tensile assembly screws for immediate field replacement.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Flow Interruption:\u003c\/strong\u003e Enhances safety by ensuring no gas migrates to the main burner during the manual reset phase.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBroad Application Range:\u003c\/strong\u003e Optimized for commercial fryers, brooders, and \u003cstrong\u003erecreational vehicle gas appliances\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandardized Pilot Fitting:\u003c\/strong\u003e Tapped for 1\/8\" pipe and adaptable to common \u003cstrong\u003epilot tubing sizes\u003c\/strong\u003e, reducing the need for additional adapters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Technician Questions:\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCan I use the 1720-802 to replace a 1720-801?\u003c\/strong\u003e No. The 1720-801 is a \"J\" model (inlet and outlet), while the 1720-802 is a \u003cstrong\u003e\"K\" model (outlet only)\u003c\/strong\u003e.
