Freedom 90^® High Efficiency
Single-Stage Gas Furnace

Multispeed blower motor - Operates quietly and efficiently, gently warming and maintaining comfort. Handles all central air
conditioning needs, too.

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 hot surface silicon nitride igniter - Starts burners electrically for safe, efficient operation. There's no pilot light constantly burning fuel.

Aluminized steel heat exchanger - Crimped, not welded, to prevent cracks from heat stress. Stamped serpentine channel offers the greatest efficiency in less space. Backed by our lifetime limited warranty.

Stainless steel secondary heat exchanger - Captures more of the
heat you pay for.

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 - Manage every function with digital accuracy. Include safety features and a built-in troubleshooting system.

Sound-insulated blower compartment - Assures the quietest possible operation.

100% fresh air option - Uses 100% outdoor air for combustion for increased equipment life and cleaner air.

Dual door latches allow easy access to the filter for cleaning or changing.

Cleanable filter means you can rinse or vacuum it without buying replacements each time.

Spring-loaded filter rack automatically adjusts for standard off-the-shelf filters.
