INSTRUCTION

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.” For California installations in SCAQMD only: This furnace does not meet the SCAQMD Rule 1111 or SJVPACD Rule 4905 NOx emission limit (14 ng/J).

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.
• 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 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.
• 60 second fixed cooling cycle blower-off delay (TDR) increases cooling performance when matched with a Nortek Global HVAC coil.
• Multi-speed direct drive blower: Designed to give a wide range of cooling capacities. Dip switches on PCB provide easy motor speed selection.
• LP convertible: Simple burner orifice and regulator spring change for ease of convertibility.
• 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.
• 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.
• PolyPro by DuraVent: These furnaces have been tested with and are approved to be installed with DuraVent’s PolyPro venting system.

NOTES:

1. To comply with government mandated efficiency standards, two openings are required for airflows above 1,600 CFM.
2. Data is shown without filter.
3. Temperature rises in the table are approximate. Actual temperature rises may vary.
4. Individual cells shaded in gray indicate a temperature rise outside of the recommended range.
5. To comply with government mandated efficiency standards, speed settings shaded in gray are not allowed in HEAT mode.
6. Unit ships with (4) speeds pre-wired. Use of the fifth speed will require changing the appropriate wires at the motor connection. Consult the wiring diagram for more information.

* NOTE:

1. Subtract 2.5 ft. for each additional 2″ elbow and 3.5 ft. for each additional 3″ elbow.
2. Two 45 degree elbows are equivalent to one 90 degree elbow.
3. One short radius elbow is equivalent to two long radius elbows.
4. Do not include termination elbows in calculation of vent length.
5. This table is applicable for elevations from sea level to 2000 ft. For higher elevations decrease vent pipe lengths by 8% per 1000 ft. of altitude.
6. Only the listed pipe materials are approved for use with FG7 Condensing Furnaces.
