Frigidaire FG7S Hight Efficiency Upflow/Horizontal And Downflow Gas Furances
Introduction
High Efficiency Up flow/Horizontal and Downflow Gas Furnaces
Induced Draft – 80+ AFUE
Input 45,000 – 126,000 Btuh
The high efficiency gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. The rounded corner jacket provides a pleasing “appliance appearance.” Design certified by CSA for application in Canada and the United States.
FEATURES AND BENEFITS
- 100% fired and tested: All units and each component are tested on the manufacturing line.
- Best packaging in the industry: Unique corner post design assures product will arrive to the homeowner dent free.
- Low Boy Height: Easy to apply in low ceiling applications, works well with taller high SEER coils, easier to handle and install.
- Tubular primary heat exchanger: Heavy gauge aluminized steel heat exchanger assures a long life.
- 30 second blower delay at start-up: Assures a warm duct temperature at furnace start-up. Adjustable blower off settings (60, 90, 120 and 180 seconds).
- 30 second post purge: Increases life of heat exchanger.
- Hot surface igniter: Innovative application of a silicon nitride igniter. Utilizes proven Smart lite® technology.
- Color coded wire harness: Designed to fit the components, all with quick-connect fittings for ease of service and replacement.
- High static blowers: All models equipped with high static blowers.
- 90 second cooling cycle blower-off delay (TDR): increases cooling performance when matched with a NORDYNE coil.
- Flexible category I venting system: May be vented with dedicated venting system or common vented with other category one appliances.
- High efficiency blower kits: Maximize efficiencies. On select units, a SEER improvement of up to 1 point is realized.
- Multi-speed direct drive blower: Designed to give a wide range of cooling capacities. Switches on PCB, provide ultra easy motor speed selection.
- LP convertible: Simple burner orifice and regulator spring change for ease of convertibility.
- Diagnostic lights for easy troubleshooting without counting flashes: Dedicated light for flame signal strength and 2 lights in combination to indicate all other fault codes with easy to recognize states without counting flashes.
- Integrated control board: Incorporates connections for electronic air cleaner and humidifier.
- Two piece door design: Enhances furnace appearance and uses captured screws to prevent loosing door screws.
- Blower Compartment: Insulated for ultra quiet operation.
