It uses a variable speed ECM motor to adjust airflow and heat output in small increments, reducing temperature swings and operating noise compared to single- or two-stage units. The downflow configuration directs conditioned air downward from the unit, making it suitable for installations where ductwork runs beneath the furnace. Licensed HVAC technicians install and commission this equipment. At 140 pounds net weight and a compact footprint, it fits residential mechanical rooms and alcove installations where space is limited.\u003c\/p\u003e\n\u003cp\u003eThis furnace is designed for residential forced-air heating systems requiring a downflow configuration. The modulating gas valve and variable speed blower motor work together to match heat output to actual load demand, which improves comfort consistency and reduces short-cycling. The unit ships in gray and includes Insta-Position Technology and pre-formed flanges for simplified venting and positioning during rough-in. Crimped heat exchangers replace traditional welded construction. This furnace is appropriate for 3-ton matched system applications in residential construction and light replacement work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e97% AFUE modulating operation for precise, efficient heat delivery\u003c\/li\u003e\n  \u003cli\u003eVariable speed motor reduces operating sound levels and improves airflow control\u003c\/li\u003e\n  \u003cli\u003eDownflow airflow configuration for under-furnace duct systems\u003c\/li\u003e\n  \u003cli\u003eInsta-Position Technology simplifies field positioning during installation\u003c\/li\u003e\n  \u003cli\u003ePre-formed flanges and crimped heat exchangers for consistent fit and long-term durability\u003c\/li\u003e\n  \u003cli\u003eLimited lifetime heat exchanger warranty with registration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style modulating downflow gas furnace for residential forced-air heating systems sized for 3-ton matched cooling applications.\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 manufacturer instructions and all applicable local codes, including IFGC requirements for gas appliances. Shut off gas supply and disconnect electrical power before any service or replacement work. Venting must be sized and routed per the furnace installation manual and local authority having jurisdiction. Do not fire the unit without confirming proper gas pressure, flue connections, and thermostat wiring are complete.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Gas Furnace\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 97%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBTU\/h Output\u003c\/strong\u003e: 70,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Stages\u003c\/strong\u003e: Modulating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Direction\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTonnage\u003c\/strong\u003e: 3 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Variable Speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEmissions Level\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\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: 28.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNet Weight\u003c\/strong\u003e: 140 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproximate Shipping Weight\u003c\/strong\u003e: 150 pounds\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  \u003cli\u003e\n\u003cstrong\u003eLabor Warranty\u003c\/strong\u003e: No Warranty\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: nf97d070m3b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GENERAL ELECTRIC","offers":[{"title":"Default Title","offer_id":51468190941490,"sku":"NF97D070M3B","price":3437.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313948064.jpg?v=1783913944","url":"https:\/\/voomisupply.com\/products\/general-electric-nf97d070m3b-gas-furnace-70000-btu-h-97-afue","provider":"Voomi Supply","version":"1.0","type":"link"}
