It regulates gas flow in heating systems with capacities from 30 to 300 cubic feet per hour (CFH), rated at 190,000 BTU\/h. The straight-through body pattern with flange simplifies inline installation, and the 1\/2-inch NPT inlet pairs with a 3\/4-inch outlet for flexible system piping. The factory outlet pressure is set at 3.5 inches water column (WC). Licensed HVAC technicians and gas appliance service professionals are the intended installers for this control.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for residential and light commercial gas-fired appliances operating on natural gas with a standing pilot ignition system. Typical applications include older-style furnaces, boilers, and unit heaters that rely on a continuously burning pilot rather than electronic ignition. The single-stage operation provides straightforward on\/off gas control, making it a direct-fit solution for standing pilot systems requiring a combination gas control in the 30 to 300 CFH capacity range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-stage combination gas control rated for 30 to 300 CFH capacity range\u003c\/li\u003e\n  \u003cli\u003e24-volt AC operating voltage for standard low-voltage thermostat compatibility\u003c\/li\u003e\n  \u003cli\u003e190,000 BTU\/h capacity supports a wide range of heating appliance sizes\u003c\/li\u003e\n  \u003cli\u003eStraight-through body pattern with flange for straightforward inline piping\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch NPT inlet and 3\/4-inch outlet for common residential and light commercial piping configurations\u003c\/li\u003e\n  \u003cli\u003eFactory outlet pressure set at 3.5 inches WC for natural gas applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement combination gas control for 24-volt AC, standing pilot, natural gas-fired appliances with system capacities between 30 and 300 CFH.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed HVAC technician or qualified gas appliance service professional in accordance with local codes and the appliance manufacturer guidelines. Shut off the gas supply fully at the upstream manual shutoff valve and allow the system to depressurize before removing the existing valve. Verify inlet and outlet pipe thread sizes match before installing, and leak-test all connections with an approved gas leak detection solution after restoring gas pressure. Never use an open flame to check for gas leaks.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 190,000 BTU\/h (30 to 300 CFH)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgnition Type\u003c\/strong\u003e: Standing Pilot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Pattern\u003c\/strong\u003e: Straight-Through with Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/2 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Pressure Setting\u003c\/strong\u003e: 3.5 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStages\u003c\/strong\u003e: Single Stage\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: RESIDEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: vr8300a3500\/u\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESIDEO","offers":[{"title":"Default Title","offer_id":51467499897138,"sku":"VR8300A3500\/U","price":210.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946132.jpg?v=1783905866","url":"https:\/\/voomisupply.com\/products\/resideo-vr8300a3500-u-single-stage-gas-valve-190000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
