It is sized for 4-ton system configurations and ships in a B cabinet form factor. Two-stage operation allows the furnace to run at a lower firing rate during moderate weather and ramp up to full capacity on the coldest days, reducing short-cycling and improving comfort. Licensed HVAC technicians install this unit in residential forced-air heating systems where a downflow air discharge configuration is required.\u003c\/p\u003e\n\u003cp\u003eThe nf80d090t4br is intended for downflow installations, meaning supply air exits through the bottom of the cabinet. This configuration is common in homes with crawl-space ductwork or where the furnace is installed in an upper-level mechanical closet discharging into floor-level supply plenums. The B cabinet sizing fits standard residential applications at the 3.5- to 4-ton range. This unit is appropriate for replacement or new-construction installations in residential gas heating systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80% AFUE steady-state efficiency meets minimum federal efficiency standards for gas furnaces\u003c\/li\u003e\n  \u003cli\u003eTwo-stage gas valve and burner operation reduces short-cycling and improves temperature consistency\u003c\/li\u003e\n  \u003cli\u003e90,000 BTU\/h heating output supports 4-ton system configurations\u003c\/li\u003e\n  \u003cli\u003eDownflow air discharge suits crawl-space and floor-plenum duct systems\u003c\/li\u003e\n  \u003cli\u003eB cabinet form factor fits standard residential furnace footprints\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style downflow gas furnace for residential forced-air heating systems requiring a B cabinet footprint and 4-ton matched 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 local mechanical codes, the International Fuel Gas Code (IFGC), and the manufacturer instructions supplied with the unit. Shut off the gas supply and disconnect electrical power before servicing or making connections. Downflow installations require a listed combustible-floor base or sub-base when the unit is set on a combustible surface. Flue venting must be configured for 80% AFUE non-condensing B-vent requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 80%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 90,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Tonnage\u003c\/strong\u003e: 4 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage Configuration\u003c\/strong\u003e: Two-Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Direction\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Size\u003c\/strong\u003e: B Cabinet\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: nf80d090t4br\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GENERAL ELECTRIC","offers":[{"title":"Default Title","offer_id":51467634147634,"sku":"NF80D090T4BR","price":1673.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947438.jpg?v=1783908883","url":"https:\/\/voomisupply.com\/products\/general-electric-nf80d090t4br-gas-furnace-90k-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
