It uses a two-stage gas valve and an ECM variable speed blower motor to deliver precise heat output while reducing energy consumption during partial-load operation. The downflow configuration directs conditioned air downward through the supply plenum, making it well-suited for installations where ductwork runs below the unit. Licensed HVAC technicians typically install and service this equipment in residential and light commercial applications.\u003c\/p\u003e\u003cp\u003eThis furnace is designed for downflow installations, commonly found in closet-style or platform-mounted applications where supply air is routed beneath the unit into a crawlspace or basement duct system. The 14-inch cabinet width fits standard narrow-width furnace cutouts. With a nominal cooling tonnage of 3 tons, it is matched to central air conditioning coil systems installed in series. The two-stage burner and ECM motor combination supports longer, lower-capacity run cycles that improve humidity control and air distribution consistency.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80% AFUE efficiency rating reduces fuel consumption compared to older standard-efficiency equipment\u003c\/li\u003e\n\u003cli\u003eTwo-stage gas valve allows low-fire and high-fire operation for improved comfort and efficiency during moderate load conditions\u003c\/li\u003e\n\u003cli\u003eECM variable speed blower motor adjusts airflow continuously to match system demand and reduce electrical draw\u003c\/li\u003e\n\u003cli\u003eDownflow configuration directs supply air downward, compatible with under-unit duct systems\u003c\/li\u003e\n\u003cli\u003e14-inch cabinet width fits standard narrow furnace openings\u003c\/li\u003e\n\u003cli\u003e3-ton nominal cooling capacity supports matched central AC or heat pump coil installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style downflow gas furnace for residential and light commercial forced-air heating systems requiring a 14-inch wide cabinet with a 50,000 BTU\/h input and downflow airflow configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed HVAC contractor in accordance with the International Fuel Gas Code (IFGC), local mechanical codes, and the manufacturer installation instructions. Shut off gas supply and disconnect electrical power before beginning any service or installation work. Proper venting, combustion air supply, and gas line sizing must be verified before startup. ECM motor control wiring should be handled carefully to avoid damage to the low-voltage circuit board connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 50000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAFUE Efficiency\u003c\/strong\u003e: 80%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage\u003c\/strong\u003e: Two Stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: ECM Variable Speed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCabinet Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Cooling Tonnage\u003c\/strong\u003e: 3 tons\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WEATHERKING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W802W0503A14DZSBAS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEATHERKING","offers":[{"title":"Default Title","offer_id":51283997229362,"sku":"W802W0503A14DZSBAS","price":1933.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278913.jpg?v=1781065497","url":"https:\/\/voomisupply.com\/products\/weatherking-w802w0503a14dzsbas-gas-furnace-50000-btu","provider":"Voomi Supply","version":"1.0","type":"link"}
