FG7T (E and N Series) Two Stage, Variable Speed, Condensing Upflow and

Downflow Gas Furnaces

Two Stage, Variable Speed, Condensing Upflow and Downflow Gas Furnaces
Induced Draft – 96% AFUE
Input 60,000 – 115,000 Btuh
The high efficiency upflow gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. The extended flush jacket provides a pleasing “appliance appearance.” Design certified by CSA for application in Canada and the United States.

FEATURES and BENEFITS

• Variable Speed Direct Drive Blower: Energy-efficient, brushless DC (ECM) motor controls airflow to provide better temperature control, humidity control and air distribution.

• SmartLite® Technology: Auto-adjusts igniter on time to extend igniter life.

• Hot Surface Igniter: Innovative application of a silicon nitride type igniter.

• 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.

• 60 Second Fixed Cooling Cycle Blower-Off Delay (TDR): Increases cooling performance when matched with a Nortek Global HVAC coil.

• Color Coded Wire Harness: Designed to fit the components, all with quick-connect fittings for ease of service and replacement.

• Diagnostic Lights: 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 Boards: With connections for electronic air cleaner, humidifier, and dehumidification.
  Ergonomically located for ease of service.

• 2 Stage Inducer: Optimizes efficiency on first stage heat and reduces sound levels.

• Heat Exchanger: Heavy gauge aluminized steel primary heat exchanger and stainless steel secondary heat exchanger assures a long life.

• 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.

• 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.

• Low Boy Height: Easy to apply in low ceiling applications, works well with taller high SEER coils, easier to handle and install.

• LP Convertible: Simple burner orifice and regulator spring change for ease of convertibility (as an accessory).

• 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.

• Furnace Air Leakage: These furnaces comply with Energy Star cabinet air leakage requirement of less than or equal to 2%. Keep the conditioned air flowing to where it’s needed.

NOTES:

1. Motor switch settings for heating speeds use HEAT switches 1, 2, 3, & 4 and for cooling speeds use COOL switches 5, 6, 7, & 8.
2. To comply with government mandated efficiency standards, two openings are required for airflows above 1,600 CFM.
3. Data is shown without filter.
4. Temperature rises in the table are approximate. Actual temperature rises may vary.
5. Individual cells shaded in gray indicate a temperature rise outside of the recommended range.
6. To comply with government mandated efficiency standards, speed settings shaded in gray are not allowed in HEAT mode.
7. When in low stage heat, the airflow is approximately 70% of the tables high value (2-stage furnaces only).
