FG7MQ
ISEER, Smartlite® Fully Modulating, Variable Speed, Condensing Upflow/Horizontal Gas Furnaces

Induced Draft – 97.0 AFUE
Input 60,000 – 120,000 Btuh

The high efficiency upflow gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. Upflow/horizontal units come ready for upflow or horizontal application. The extended flush jacket provides a pleasing “appliance appearance.” Design certified by CSA for application in Canada and the United States.

When registered, this product is upgraded to a limited lifetime heat exchanger warranty.

FEATURES and BENEFITS

i SEER: Energy efficient brushless DC (ECM) motor gives up to 1 SEER point efficiency gain in cooling.
Modulating heating operation Includes:
- Modulating gas valve from 100% to 50% input in 5% increments.
- Time proportioning modulation down to 15%.
- Variable speed inducer and blower.
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.
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 ni-tride type 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.
Flexible category IV venting system: May be vertically or horizontally vented using either a one-pipe or two-pipe system for maximum flexibility in installation.
High Static Blowers: All models equipped with high static blowers.
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 and stainless steel secondary heat exchanger assures a long life.
90 second fixed cooling cycle blower-off delay (TDR): increases cooling performance when matched with a NORDYNE coil.
LP convertible: Simple burner orifice change for ease of convertibility.
Diagnostic lights for easy troubleshooting without counting flashess: 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.
Incorporates integrated control board : with connections for electronic air cleaner and humidifier.
Two piece door design: Enhances furnace appearance and uses captured screws to prevent losing door screws.
Blower Compartment: Sealed door to reduce air leakage and insulated for ultra quiet operation.
Sealed Vestibule: Reduces burner and inducer sound levels.
