It delivers 80,000 BTU input capacity at 96% AFUE, recovering nearly all available heat from combustion before exhaust gases are vented. A two-stage burner pairs with a variable-speed ECM blower motor to modulate output based on load demand, reducing short-cycling and improving comfort consistency. The 24-volt control circuit is compatible with standard thermostat wiring. This unit is configured for upflow, horizontal left, and horizontal right installation orientations. Licensed HVAC technicians handle installation, commissioning, and any conversion procedures.\u003c\/p\u003e\n\u003cp\u003eThe A952V080BU4SA is suited for residential forced-air heating systems in medium to larger homes requiring high-efficiency gas heat. The upflow and horizontal orientations support installation in utility rooms, closets, basements, attics, and crawlspace-adjacent mechanical spaces. The variable-speed blower delivers a nominal 1,600 CFM airflow, making it compatible with properly sized duct systems for whole-home heating. First-stage heating capacity is rated at 52,000 BTU, allowing the unit to operate at reduced output during mild weather conditions and only escalate to full output when the load demands it.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80,000 BTU input capacity with 96% AFUE high-efficiency rating\u003c\/li\u003e\n  \u003cli\u003eTwo-stage burner for load-matching heat output and reduced short-cycling\u003c\/li\u003e\n  \u003cli\u003eVariable-speed ECM blower motor rated at 1,600 nominal CFM\u003c\/li\u003e\n  \u003cli\u003eMulti-position installation: upflow, horizontal left, and horizontal right\u003c\/li\u003e\n  \u003cli\u003e24-volt control interface compatible with standard low-voltage thermostats\u003c\/li\u003e\n  \u003cli\u003eField-convertible to propane with an optional LP kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe A952V080BU4SA is an Ameristar by Trane variable-speed direct-vent condensing gas furnace.

Shut off gas supply and disconnect electrical power before beginning any service or installation work. Venting must be installed per direct-vent specifications; do not common-vent this appliance with other gas appliances. Propane conversion requires an approved LP kit and must be completed by a qualified technician before operating the unit on LP gas.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Heating Capacity\u003c\/strong\u003e: 80,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFirst Stage Heating Capacity\u003c\/strong\u003e: 52,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 96%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEfficiency Tier\u003c\/strong\u003e: High Efficiency\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower Motor Type\u003c\/strong\u003e: Variable Speed ECM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Airflow\u003c\/strong\u003e: 1,600 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Positions\u003c\/strong\u003e: Upflow, Horizontal Left, Horizontal Right\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas (field-convertible to propane)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting Type\u003c\/strong\u003e: Direct Vent (condensing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 17.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 28.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 34 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 135 pounds\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: A952V080BU4SA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51217048502578,"sku":"A952V080BU4SA","price":2848.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308796124.webp?v=1780588645","url":"https:\/\/voomisupply.com\/products\/runtru-a952v080bu4sa-gas-furnace-80k-btu-96-afue-two-stage-variable-speed","provider":"Voomi Supply","version":"1.0","type":"link"}
