Freedom® 90 Single Stage
Induced draft venting quietly draws hot gases through the heat exchanger, maximizing the heat transfer efficiencies of the exchanger design.
Multi-port in-shot burners perfectly shape the flame cone for the maximum heat possible, while using less fuel.
Adaptive silicon nitride hot surface igniter starts burners electrically for safe, efficient operation. There's no pilot light constantly burning fuel.
Sealed combustion means the burner compartment is sealed allowing for quieter operation and regional code compliance. (AUX/ADX models only).
Aluminized steel heat exchanger is crimped, not welded, to prevent cracks from heat stress. Stamped serpentine channel offers the greatest efficiency in less space. Backed by a lifetime limited warranty.
Heavy steel insulated cabinet holds more heat in the furnace to better warm your home. Also assures greater durability and quieter operation.
Self-diagnostic controls are the solid-state brain of the Freedom® 90 Single-Stage and manage every function with digital accuracy. Includes safety features and a built-in troubleshooting system.
AL29-4C™ stainless steel secondary heat exchanger captures more of the heat you pay for. Backed by a lifetime limited warranty.
Internal vent pipe is made of long-lasting CPVC material
Multi-speed blower motor operates quietly and efficiently, gently warming and maintaining comfort. Handles all central air conditioning needs for year ‘round comfort.
