It delivers 80,000 BTU\/h of heating input at 96% AFUE, meaning the vast majority of fuel consumed is converted directly to usable heat. The unit uses a two-stage burner paired with a variable-speed ECM blower, allowing the system to modulate output based on demand rather than running at full capacity continuously. Nominal airflow is 1,600 CFM. Control voltage is 24 volts. The cabinet measures 17.5 inches wide, 28.75 inches deep, and 34 inches tall, making it compatible with standard residential equipment closets and utility rooms.\u003c\/p\u003e\u003cp\u003eThis furnace is designed for residential forced-air heating applications in medium-sized homes. The upflow configuration suits installations where the supply air is discharged upward into the duct system, as is common in basement and utility room setups. The unit is field-convertible to propane operation using an optional LP conversion kit, giving installers flexibility for homes without natural gas service. When paired with a compatible cooling coil and air conditioner or heat pump, it functions as the air handler for the complete system. The two-stage burner reduces short cycling and improves comfort consistency in mild and cold conditions alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80,000 BTU\/h input capacity with 96% AFUE for high-efficiency natural gas heating\u003c\/li\u003e\n\u003cli\u003eTwo-stage burner operation reduces short cycling and improves temperature consistency\u003c\/li\u003e\n\u003cli\u003eVariable-speed ECM blower rated at 1,600 CFM nominal airflow for precise air distribution\u003c\/li\u003e\n\u003cli\u003eUpflow and horizontal left\/right installation configurations supported\u003c\/li\u003e\n\u003cli\u003eField-convertible to propane (LP) with an optional conversion kit\u003c\/li\u003e\n\u003cli\u003e24-volt control circuit compatible with standard residential thermostat wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe A952V080BU4SB is noted as a replacement for model A952V080BU4SA.

Shut off gas supply and disconnect electrical power before beginning any service or replacement work. Venting must be configured to match the 96% AFUE condensing category, which requires approved PVC or CPVC flue pipe and a proper condensate drainage path. Do not operate the unit before verifying gas line pressure, combustion air supply, and all electrical connections are correct and secure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating Input Capacity\u003c\/strong\u003e: 80,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAFUE Rating\u003c\/strong\u003e: 96%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBurner Stages\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlower 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\u003eCabinet Width\u003c\/strong\u003e: 17.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCabinet Depth\u003c\/strong\u003e: 28.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCabinet Height\u003c\/strong\u003e: 34 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Orientation\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\u003eUnit Weight\u003c\/strong\u003e: 135 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: A952V080BU4SB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51195725349170,"sku":"A952V080BU4SB","price":2848.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308796105.jpg?v=1780589045","url":"https:\/\/voomisupply.com\/products\/trane-a952v080bu4sb-gas-furnace-80-000-btu-17-5-inches-width-replacement-a952v080bu4sa","provider":"Voomi Supply","version":"1.0","type":"link"}
