This \u003cstrong\u003e7000AMVR series\u003c\/strong\u003e valve features a 1\/2\" NPT inlet and 1\/2\" NPT outlet with additional side taps, offering a high-capacity throughput of \u003cstrong\u003e100,000 BTU\u003c\/strong\u003e. Engineered for \u003cstrong\u003ewall thermostat actuation\u003c\/strong\u003e, it operates on a 250mV to 750mV signal, making it a reliable choice for \u003cstrong\u003efurnaces\u003c\/strong\u003e, wall heaters, and boilers without requiring external line voltage. The unit comes factory-set for \u003cstrong\u003eNatural Gas\u003c\/strong\u003e at a \u003cstrong\u003e3.5\" WC\u003c\/strong\u003e regulation point, though it is field-convertible with the appropriate regulator kit. Techs will appreciate the \u003cstrong\u003estraight-thru design\u003c\/strong\u003e and the inclusion of reducer bushings for versatile 1\/2\" x 3\/8\" applications. Built with a separate automatic pilot safety valve, it ensures immediate gas shutoff during pilot outage, maintaining system integrity in demanding environments.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUniversal Installation:\u003c\/strong\u003e Multi-positional mounting capability (except upside down) allows for easy retrofitting in tight mechanical closets or equipment housings.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Compatibility:\u003c\/strong\u003e Replaces a wide range of \u003cstrong\u003eHoneywell VS8148\u003c\/strong\u003e and \u003cstrong\u003eAllpoints\u003c\/strong\u003e millivolt valves used in vintage and modern gas-fired appliances.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eReliable Pilot Safety:\u003c\/strong\u003e Features an independent automatic safety magnet and a manual gas cock (Off-Pilot-On) for standard service procedures.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIntegrated Protection:\u003c\/strong\u003e Includes \u003cstrong\u003einlet filtered screens\u003c\/strong\u003e and a pilot gas filter to prevent debris from fouling the internal diaphragm or orifices.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this gas valve for LP (Propane) applications?\u003c\/strong\u003e\u003cbr\u003e\nThe 700-502 is factory-configured for Natural Gas. To use it with LP, you must install a 1751-013 regulator conversion kit to achieve the required 11.0\" WC pressure. Always verify the orifice size of the appliance before conversion.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this valve require a specific thermopile connection?\u003c\/strong\u003e\u003cbr\u003e\nThis model is designed for use with standard \u003cstrong\u003etwo-lead thermopiles\u003c\/strong\u003e. It features combination screw\/spade terminals (1\/4\" and 3\/16\" NEMA standards) to ensure secure electrical contact and prevent miswiring during field replacement.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat should I check if the valve fails to open?\u003c\/strong\u003e\u003cbr\u003e\nFirst, verify the \u003cstrong\u003emillivolt output\u003c\/strong\u003e of the thermopile under load. If the closed-circuit reading is below 100mV, the valve may not actuate. Also, ensure the thermostat wiring hasn't exceeded the maximum recommended length for 750mV systems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
