This B-cabinet unit measures 33 inches tall, 17.5 inches wide, and 28.375 inches deep, making it suitable for closet and utility-room installations where downflow airflow is required. A constant-torque motor provides consistent airflow delivery while reducing energy draw at the blower. Compatible with R410A and R454B refrigerant systems on the cooling side, this furnace integrates into split-system applications. Licensed HVAC contractors are the intended installers for this equipment.\u003c\/p\u003e\u003cp\u003eThis furnace is built for residential downflow applications where supply air is delivered through the bottom of the unit into an underfloor duct system. The B-cabinet width fits standard residential platform or closet installations designed around the 17.5-inch cabinet class. Single-stage heating operation means the gas valve and burner operate at one fixed rate, simplifying controls integration and keeping installation straightforward in applications where two-stage or modulating operation is not required. Standard emissions compliance makes it suitable for most jurisdictions without additional permitting related to low-NOx mandates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80% AFUE efficiency rating reduces fuel consumption compared to non-condensing legacy equipment\u003c\/li\u003e\n\u003cli\u003eSingle-stage heating for straightforward thermostat and control wiring\u003c\/li\u003e\n\u003cli\u003eConstant-torque blower motor for consistent static pressure performance across duct systems\u003c\/li\u003e\n\u003cli\u003eDownflow airflow configuration for underfloor or platform-mount duct installations\u003c\/li\u003e\n\u003cli\u003eCompatible with R410A and R454B refrigerant on split-system cooling coil applications\u003c\/li\u003e\n\u003cli\u003eLimited lifetime heat exchanger warranty with product registration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM downflow gas furnace for residential split-system heating applications using B-cabinet platform installations.

Shut off gas supply and disconnect electrical power before servicing or replacing any furnace component. Downflow furnaces require a combustible-floor base or listed non-combustible platform when installed over combustible flooring. Verify duct static pressure and gas supply pressure are within the manufacturer-specified ranges before commissioning the unit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 80%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating Output\u003c\/strong\u003e: 66,000\/54,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating Stages\u003c\/strong\u003e: Single-Stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Direction\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Constant Torque\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: R410A\/R454B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmissions Level\u003c\/strong\u003e: Standard Emissions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 33 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 17.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Depth\u003c\/strong\u003e: 28.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Weight\u003c\/strong\u003e: 120 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate Shipping Weight\u003c\/strong\u003e: 130 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParts Warranty\u003c\/strong\u003e: Limited 5-year entire appliance; Limited 10-year entire appliance with registration; Limited 20-year heat exchanger; Limited lifetime heat exchanger with registration\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: nf80d070s3br\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GENERAL ELECTRIC","offers":[{"title":"Default Title","offer_id":51467685331250,"sku":"NF80D070S3BR","price":1372.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313948069.jpg?v=1783910302","url":"https:\/\/voomisupply.com\/products\/ge-nf80d070s3br-80-afue-downflow-gas-furnace-70k-btu","provider":"Voomi Supply","version":"1.0","type":"link"}
