Trane A952V100CD5SB Gas Furnace 100000 Btu/h 96% Afue Variable Speed Two Stage Downflow

Product Description

The Trane A952V100CD5SB is a two-stage, variable-speed natural gas furnace rated at 100,000 BTU/h input and 96% AFUE, designed for dedicated downflow installations. The unit runs on a variable-speed ECM blower motor that modulates airflow to match heating demand, improving comfort and reducing energy use compared to single-speed units. Two-stage gas valve operation allows the furnace to run at a reduced firing rate during milder conditions and ramp to full capacity when outdoor temperatures drop. This furnace is sized for residential applications and is installed by licensed HVAC technicians.

The A952V100CD5SB is part of the RunTru by Trane RT Series and is configured for downflow airflow only, meaning supply air discharges downward through the unit. The cabinet measures 21 inches wide and is suited for closet or alcove installations where downflow duct configurations are present. This unit is appropriate for residential heating applications and is controlled via a 24-volt low-voltage thermostat circuit. Proper sizing of the duct system to match the variable-speed blower performance is essential for optimal operation.

Key Features

• 100,000 BTU/h input capacity with 96% AFUE for high-efficiency natural gas combustion
• Two-stage gas valve reduces fuel consumption during partial-load heating conditions
• Variable-speed ECM blower motor provides consistent airflow and quiet operation
• Dedicated downflow configuration for installations requiring downward air discharge
• 21-inch cabinet width fits standard residential closet and alcove installations
• 24-volt control circuit compatible with standard low-voltage thermostat wiring

Compatibility

Designed for use in dedicated downflow residential gas furnace applications as part of the RunTru by Trane RT Series. Consult Trane engineering documentation to confirm compatible coil cabinets, air handlers, and thermostat controls before ordering.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer's installation instructions. Shut off gas supply and disconnect electrical power before beginning any service work on the unit. Downflow furnaces require a combustible-floor base or an approved non-combustible subbase when installed over a combustible surface. Flue venting must be sized and configured per the International Fuel Gas Code and local jurisdiction requirements for high-efficiency condensing appliances.
