FEATURES and BENEFITS

  • I SEER: 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 arev 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, sasier 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 setings (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 Smartite 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 col.
  • Flexible category I venting system: May be vented with dedicated venting system or common vented with other category one appliances.
  • Variable speed blower kit: Upgradable to full variable speed with kit.
  • LP convertible: Simple bumerantice 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 Ilashes
  • Integrated control board: Incorporates connections for electronic air deaner, humidifier and winning Two piece door design: Enhances furnace appearance and uses captured screws to prevent loosing door screws.
  • Blower Compartment: Insulated for ultra quiet operation.
  • Stage Inducer: Optimizes efficiency on first stage heat and reduces sound levels

Note 

  1. Motor Switch Ich Settings are for heating speeds using HEAT switches 1.. 2, 3, & 4 and cooling speeds using COOL switches 5, 6, 7. & 8
  2. Two openings are required for airflows above 1600 CFM if the filter(s) is (are) adjacent to the furnace.
  3. Data is shown without filter.
  4. Temperature rises in the table are approximate. Actual temperature rises may vary.
  5. Temperature rises that are shaded in grey are not recommended.
