Legacy™ 96% AFUE, Single Stage, Fixed Speed, Gas Furnace (FER), 115/1

  • California Prop 65

The 915SB Multipoise Condensing Gas Furnace features the single-stage Legacy™ System. The fixed-speed, constant torque (FCT) ECM blower motor is at the heart of the electrical efficiency provided by this furnace. With an Annual Fuel Utilization Efficiency (AFUE) of up to 96.2% AFUE, this furnace provides added savings over standard gas furnaces. The Legacy™ Gas Furnace features 4-way multipoise installation flexibility, and is available in eleven model sizes. All sizes except the 26,000 BTUH model can be vented for direct vent/two-pipe, ventilated combustion air, or single-pipe applications. The 26,000 BTUH model can use the same 2-pipe venting system using outside air for combustion, but is not considered direct-vent. A Bryant Legacy Control and Legacy Air Conditioner or Heat Pump, can be used to form a complete Legacy Line System. All sizes are design certified in Canada. Specific sizes are design certified for use in Manufactured Housing (Mobile Home) applications when used with factory-approved MH accessory kit.
