The two-stage gas valve reduces the burner to a lower firing rate during mild heating demand, cutting short-cycling and improving temperature consistency throughout the structure. At 96% AFUE, nearly all fuel input is converted to usable heat, reducing operating costs compared to standard-efficiency equipment. This unit is designed for installation in multiple orientations, making it suitable for upflow, downflow, or horizontal applications depending on the mechanical room layout. Licensed HVAC technicians perform installation and commissioning on this class of equipment.\u003c\/p\u003e\n\u003cp\u003eThe W962W1005A21M4SBAS is designed for residential and light-commercial forced-air heating applications where natural gas is the available fuel source. The multi-position configuration supports flexible duct system layouts, and the 5-ton nominal cooling capacity rating makes it a match for air conditioning coils up to 5 tons. The unit carries a 21-inch cabinet width, which fits standard platform and closet installations where that dimension is accommodated. It is well suited for new construction and retrofit replacement projects requiring high-efficiency, multi-stage heating performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e96% AFUE efficiency rating reduces fuel consumption compared to standard-efficiency furnaces\u003c\/li\u003e\n  \u003cli\u003eTwo-stage heating operation lowers blower noise and improves comfort during partial-load conditions\u003c\/li\u003e\n  \u003cli\u003eMulti-position design supports upflow, downflow, and horizontal installation orientations\u003c\/li\u003e\n  \u003cli\u003e100,000 BTU\/h heat input capacity for larger residential and light-commercial structures\u003c\/li\u003e\n  \u003cli\u003e5-ton nominal cooling airflow rating for compatibility with matched cooling coil systems\u003c\/li\u003e\n  \u003cli\u003eNatural gas fuel type for use where NG service is available\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a multi-position natural gas furnace replacement or new-installation unit for residential and light-commercial forced-air systems requiring 100,000 BTU\/h capacity at 96% AFUE with two-stage operation and a 5-ton nominal cooling match.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed HVAC technician in accordance with the National Fuel Gas Code (NFPA 54\/ANSI Z223.1) and all applicable local codes. Shut off the gas supply and disconnect electrical power before beginning any service or replacement work. Proper venting must be configured per the manufacturer installation instructions for this efficiency class, which typically requires PVC or CPVC flue piping rather than traditional metal B-vent. Verify cabinet orientation and duct connection requirements before mounting to ensure proper airflow direction and condensate drainage.\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\u003eHeating Capacity\u003c\/strong\u003e: 100,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE Efficiency\u003c\/strong\u003e: 96%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage\u003c\/strong\u003e: Two Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Multi-Position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Cooling Capacity\u003c\/strong\u003e: 5 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Width\u003c\/strong\u003e: 21 inches\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: WEATHERKING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W962W1005A21M4SBAS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEATHERKING","offers":[{"title":"Default Title","offer_id":51284152222002,"sku":"W962W1005A21M4SBAS","price":2476.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278924.png?v=1781069872","url":"https:\/\/voomisupply.com\/products\/weatherking-w962w1005a21m4sbas-100k-btu-96-gas-furnace","provider":"Voomi Supply","version":"1.0","type":"link"}
