Freedom 80® Two-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 ignitor starts burning electically 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 the 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 size off-the-shelf filters (on upflow models only). |
| 11. |
Automotive grade gaskets and insulated blower door reduce operating sound and air infiltration. |
| 12. |
Two-stage gas valve works efficiently with the multi-speed motor, providing only as much fuel as each stage requires. |
| 13. |
Multi-speed blower motor operates quietly and efficiently, gently warming and maintaining comfort. Handles all central air conditioning needs, too. | |
