Key Features

High Efficiency — 96% AFUE

• 96% Annual Fuel Utilization Efficiency means most of the fuel energy is converted to heat.

• Helps lower heating bills compared to standard-efficiency furnaces.

Two-Stage Heating Operation

• Features a two-stage gas valve:

  • High stage for colder conditions — full heat output.

• Delivers more consistent comfort, smaller temperature swings, and fewer on/off cycles than single-stage models.
