Operating at 97% AFUE means the unit converts 97 cents of every fuel dollar into usable heat, a standard associated with condensing gas furnaces that recover latent heat from flue gases. The two-stage gas valve allows the furnace to run at a reduced fire rate during mild conditions and step up to full capacity during peak heating demand, improving comfort and reducing short-cycling. At 4 tons of airflow capacity, this unit is sized for systems with matching cooling equipment. It is installed by licensed HVAC technicians in residential or light-commercial applications requiring a downflow configuration.\u003c\/p\u003e\n\u003cp\u003eThis furnace is designed for downflow installations where supply air is discharged downward through the unit, typically into a crawlspace or subfloor duct system. The 4-ton airflow rating makes it appropriate for paired split systems or package system applications in mid-to-large residential structures. The 70,000 BTU\/h input class covers a wide range of heating loads in moderate to colder climates. HVAC contractors installing this unit should verify that the duct system, venting, and gas supply are properly sized to match rated capacity and comply with local mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e97% AFUE rating for high-efficiency condensing furnace operation\u003c\/li\u003e\n  \u003cli\u003e70,000 BTU\/h heating capacity suits mid-to-large residential heating loads\u003c\/li\u003e\n  \u003cli\u003eTwo-stage operation reduces short-cycling and improves temperature consistency\u003c\/li\u003e\n  \u003cli\u003eDownflow air discharge configuration for crawlspace and subfloor duct systems\u003c\/li\u003e\n  \u003cli\u003e4-ton airflow capacity matches common split-system cooling equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for downflow gas furnace installations in residential and light-commercial forced-air heating systems requiring a 97% AFUE, two-stage, 70,000 BTU\/h condensing furnace with 4-ton airflow capacity.\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 current edition of the International Fuel Gas Code (IFGC) and all applicable local mechanical codes. Shut off gas supply and disconnect electrical power before any service work. Condensing furnaces require a Category IV sealed venting system using approved materials rated for condensate and positive flue pressure. Verify condensate drainage is properly pitched and routed before startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 97%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 70,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Capacity\u003c\/strong\u003e: 4 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage Configuration\u003c\/strong\u003e: 2-Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Direction\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 14.5 inches x 17.5 inches x 33 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 140 pounds\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: General Electric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NF97D070V4B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GENERAL ELECTRIC","offers":[{"title":"Default Title","offer_id":51506591760690,"sku":"NF97D070V4B","price":2895.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/NF97D070V4B.jpg?v=1784926494","url":"https:\/\/voomisupply.com\/products\/general-electric-nf97d070v4b-gas-furnace-97-afue-70000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
