TECHNICAL SPECIFICATIONS
FG7T (A and K Series)
iSEER, Smartlite®
Two Stage, Variable Speed, High Efficiency Upflow/Horizontal and Downflow Gas
Furnaces
Induced Draft – 80 + AFUE Input 60,000 – 140,000 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.
WARRANTY
- 10 Year all-parts warranty.
- 10 Year Quality Pledge to replace the unit if the heat exchanger fails within the first 10 years of operation, to the original owner.
- Consumer product registration required for 10 year All Parts Warranty and Quality Pledge within a limited period of time after the installation. See current warranty document or visit our consumer web site listed on the back of this document for warranty details.
- When registered, this product is upgraded to a limited lifetime heat exchanger warranty.
FEATURES and BENEFITS
- iSEER: Energy efficient brushless DC (ECM) motor gives up to 1 SEER point efficiency gain in cooling.
- 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.
- LowBoy Height: Easy to apply inlowceiling 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.
- Two Stage Inducer: Optimizes efficiency on first stage heat and reduces sound levels.
- Hot surface igniter: Innovative application of a silicon nitride igniter. Utilizes proven Smartlite® 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 | venting system: May be vented with dedicated venting system or common vented with other category one appliances.
- LPconvertible: 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, humidifier and twinning.
- Two piece door design: Enhances furnace appearance and uses captured screws to prevent loosing door screws.
- Blower Compartment: Insulated for ultra quiet operation.
