American Standard: Freedom 80 Single-Stage Gas Furnace
Freedom 80® Single-Stage 
Gas Furnace |
|
|
1. |
Induced draft venting quietly draws hot gases through the heat exchanger, maximizing the heat transfer efficiencies of the exchanger design. |
2. |
Multi-port in-shot burners perfectly shape the flame cone for the maximum heat possible, while using less fuel. |
3. |
Adaptive silicon nitride hot surface igniter starts burners electrically for safe, efficient operation. There's no pilot light constantly burning fuel. |
4. |
Aluminized steel heat exchanger is crimped, not welded, to prevent cracks from heat stress. Stamped serpentine channel offers greatest efficiency in less space. Backed by our 20-year, non-prorated, limited warranty. |
5. |
Heavy steel insulated cabinet holds more heat in the furnace to better warm your home. Also assures greater durability and quieter operation. |
6. |
Self-diagnostic controls are the solid-state brain of the Freedom® 80 and manage every function with digital accuracy. Includes safety features and a built-in troubleshooting system. |
7. |
Dual door latches allow easy access to the filter for cleaning or changing (on upflow models only). |
8. |
Sound insulated blower compartment assures the quietest possible operation. |
9. |
Cleanable filter |
10. |
Spring-loaded filter rack automatically adjusts for standard off-the-shelf filters (on upflow models only). |
11. |
Automotive grade gaskets and insulated blower door reduce operating sound and air infiltration. |
