Part of the RunTru by Trane RT Series, this unit delivers 80,000 BTU\/h of input capacity and operates at 95% AFUE, producing approximately 76,000 BTU\/h of usable heat output. The multi-speed blower motor allows the unit to match airflow to system demand. An integrated furnace control board manages sequencing, diagnostics via a 7-segment LED display, and low-voltage thermostat communication. This furnace is installed by licensed HVAC technicians in residential applications where a downflow configuration is required.\u003c\/p\u003e\n\u003cp\u003eThe A951X080BD4SA is designed exclusively for downflow installations, making it suited for applications where conditioned air is delivered downward through the floor or a plenum below the unit. The 17.5-inch cabinet width fits standard platform or closet installations. The unit is a direct-vent, condensing design, meaning it draws combustion air from outdoors and vents flue gases through PVC piping rather than a conventional B-vent flue. It is appropriate for residential heating applications in moderate to colder climates where high-efficiency gas equipment is preferred or code-required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80,000 BTU\/h input with approximately 76,000 BTU\/h output at 95% AFUE\u003c\/li\u003e\n  \u003cli\u003eSingle-stage gas valve with multi-speed blower for flexible airflow matching\u003c\/li\u003e\n  \u003cli\u003eDedicated downflow-only configuration with 17.5-inch cabinet width\u003c\/li\u003e\n  \u003cli\u003eDirect-vent condensing design with PVC flue venting — no B-vent required\u003c\/li\u003e\n  \u003cli\u003eIntegrated furnace control with 7-segment LED display for onboard diagnostics\u003c\/li\u003e\n  \u003cli\u003e5-amp control board fuse and low-voltage terminal strip for thermostat wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style downflow condensing gas furnace for residential systems requiring a 17.5-inch cabinet in a downflow orientation.

Shut off gas supply and disconnect electrical power before servicing or connecting any components. This unit is rated for downflow installation only and must not be converted to upflow or horizontal orientation. PVC flue and condensate drainage lines must be routed and pitched per the installation manual to prevent blockage or freeze damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Capacity\u003c\/strong\u003e: 80,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Capacity\u003c\/strong\u003e: 76,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE Rating\u003c\/strong\u003e: 95%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStaging\u003c\/strong\u003e: Single Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower Motor Type\u003c\/strong\u003e: Multi Speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting Type\u003c\/strong\u003e: Direct Vent Condensing (PVC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Direction\u003c\/strong\u003e: Downflow Only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Width\u003c\/strong\u003e: 17.5 inches\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: Trane\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A951X080BD4SA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51195727544626,"sku":"A951X080BD4SA","price":2015.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308796023.jpg?v=1780589077","url":"https:\/\/voomisupply.com\/products\/trane-a951x080bd4sa-gas-furnace-80-000-btu-17-5-inches-width","provider":"Voomi Supply","version":"1.0","type":"link"}
