It is built in a B-cabinet configuration, making it suitable for installations where a downflow discharge orientation is required. The 80% AFUE rating means 80 cents of every fuel dollar is converted to usable heat. Single-stage operation delivers consistent heat output at full capacity whenever the thermostat calls for heat. Licensed HVAC technicians install and commission this unit in residential or light commercial settings.\u003c\/p\u003e\u003cp\u003eThis furnace is designed for downflow applications where the supply air is discharged through the bottom of the cabinet and into a floor-level or under-floor duct system. The B-cabinet sizing fits standard furnace closets and alcoves dimensioned for mid-capacity residential heating equipment. It is intended for use in natural gas systems and pairs with a standard single-stage thermostat. This unit is a practical choice for replacing aging downflow furnaces in existing duct layouts that require bottom-discharge airflow.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80% AFUE efficiency rating for reliable, code-compliant heating performance\u003c\/li\u003e\n\u003cli\u003e70,000 BTU\/h heating capacity suited for mid-size residential applications\u003c\/li\u003e\n\u003cli\u003eSingle-stage gas valve provides straightforward, consistent heat delivery\u003c\/li\u003e\n\u003cli\u003eDownflow discharge orientation for compatibility with floor and crawlspace duct systems\u003c\/li\u003e\n\u003cli\u003eB-cabinet configuration fits standard residential furnace enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style downflow gas furnace replacement for residential heating systems requiring a B-cabinet, bottom-discharge configuration with a single-stage control circuit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the International Fuel Gas Code (IFGC). Shut off the gas supply and disconnect electrical power before beginning any work on the existing system. Verify that the existing venting, gas line sizing, and duct static pressure are appropriate for this unit before completing the installation. Do not operate the furnace without confirming proper flue venting and gas leak testing at all connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 70,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 80%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage Configuration\u003c\/strong\u003e: Single Stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Orientation\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCabinet Size\u003c\/strong\u003e: B Cabinet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: nf80d070s3b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GENERAL ELECTRIC","offers":[{"title":"Default Title","offer_id":51467642274098,"sku":"NF80D070S3B","price":1408.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947440.jpg?v=1783909148","url":"https:\/\/voomisupply.com\/products\/general-electric-nf80d070s3b-downflow-gas-furnace-70k-btu","provider":"Voomi Supply","version":"1.0","type":"link"}
