It uses a constant torque motor for consistent airflow delivery and features crimped heat exchangers rather than welded construction. Pre-formed flanges and Insta-Position Technology simplify installation positioning during rough-in. This unit is designed for residential forced-air heating systems and is installed by licensed HVAC technicians. The gray cabinet finish and compact footprint make it suitable for utility closet and alcove applications where downflow air discharge is required.\u003c\/p\u003e\u003cp\u003eThis furnace is configured for downflow airflow, directing conditioned air downward into the supply plenum or subfloor duct system. It is sized at 3 tons of air-handling capacity and rated for standard emissions levels, making it appropriate for residential installations in most jurisdictions. Typical applications include single-family homes and light commercial spaces where a single-stage heating system meets the load requirement. Licensed HVAC professionals handle sizing, venting, and commissioning of this unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45,000 BTU\/h heating output at 80% AFUE efficiency\u003c\/li\u003e\n\u003cli\u003eSingle-stage operation for straightforward control integration\u003c\/li\u003e\n\u003cli\u003eConstant torque motor for stable, consistent airflow across static pressure variations\u003c\/li\u003e\n\u003cli\u003eCrimped heat exchangers eliminate weld-joint failure points\u003c\/li\u003e\n\u003cli\u003ePre-formed flanges with Insta-Position Technology for faster field installation\u003c\/li\u003e\n\u003cli\u003eDownflow air discharge configuration for subfloor or under-unit duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style downflow gas furnace for residential forced-air heating systems requiring a single-stage, 80% AFUE unit with downflow discharge.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed HVAC technician in accordance with local codes and the applicable edition of the International Fuel Gas Code (IFGC). Shut off gas supply and disconnect electrical power before servicing or replacing any components. Proper venting must be verified for flue gas exhaust per manufacturer guidelines and local authority having jurisdiction. Do not attempt to modify the heat exchanger, burner assembly, or gas valve without manufacturer authorization.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Gas Furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating Output\u003c\/strong\u003e: 45,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 80%\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\u003eTonnage\u003c\/strong\u003e: 3 Ton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Constant Torque\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: 14.5 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: 110 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate Shipping Weight\u003c\/strong\u003e: 120 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\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: nf80d045s3a\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GENERAL ELECTRIC","offers":[{"title":"Default Title","offer_id":51467360993586,"sku":"NF80D045S3A","price":1323.88,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313948073.jpg?v=1783902063","url":"https:\/\/voomisupply.com\/products\/general-electric-nf80d045s3a-gas-furnace-45k-btu-80-afue","provider":"Voomi Supply","version":"1.0","type":"link"}
