It operates in a B-size cabinet measuring 17.5 inches wide and is designed for downflow-only installations. The two-stage gas valve delivers a first-stage input of 26,000 BTU\/h and a second-stage input of 40,000 BTU\/h, allowing the system to run at lower capacity during mild conditions and ramp up when the load demands it. A variable-speed ECM blower motor adjusts airflow continuously to match system demand, improving comfort and reducing operating noise. Licensed HVAC technicians install and commission this unit.\u003c\/p\u003e\u003cp\u003eThe A952V040BD3SA is suited for residential downflow applications where the supply air discharges through the bottom of the cabinet into a floor plenum or basement duct system. The 17.5-inch cabinet width fits standard B-size platform installations. It is part of the RunTru by Trane RT Series and is designed for natural gas service. This unit has been listed as a compatible component in split-system configurations alongside matched air conditioning equipment using R454B refrigerant, making it appropriate for new installations requiring current refrigerant compliance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-stage operation: 26,000 BTU\/h first stage and 40,000 BTU\/h second stage input for load-matched heating\u003c\/li\u003e\n\u003cli\u003e96% AFUE condensing efficiency for high-efficiency natural gas heating\u003c\/li\u003e\n\u003cli\u003eVariable-speed ECM blower motor for quiet, efficient airflow management\u003c\/li\u003e\n\u003cli\u003eDownflow-only cabinet configuration with 17.5-inch width for B-size platform fit\u003c\/li\u003e\n\u003cli\u003e24-volt low-voltage control circuit compatible with standard thermostat wiring\u003c\/li\u003e\n\u003cli\u003eCertified to ANSI Z21.47 \/ CSA 2.3 for natural gas and LP gas applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe A952V040BD3SA has been documented as a compatible furnace component in split-system configurations paired with the A5AC3036A1 condensing unit and the 5MXCB004AC6HCA coil using R454B refrigerant.
