• Clean and quiet operation: Due to the unique design of in-shot burners, location of inducer and use of insulation.
• Fixed 30 second blower delay: At burner start-up assures a warm outlet air temperature at furnace start-up. Adjustable blower off settings (60, 90, 120 and 180 seconds).
• Fixed 30-second post purge: Increases life of heat exchanger.
• Dependable, hot surface ignitor: Innovative application of silicon nitride type igniter. Utilizes proven Smartlite®technology.
• Tubular primary heat exchanger:Heavy gauge aluminized steel heat exchanger assures a long life.
• 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 NORDYNE coil.
• Sealed combustion approved for direct vent furnace,category IV venting system. May be vertically or horizontally vented using a two-pipe system for maximum flexibility in installation.
• LP convertible: Simple burner orifice and gas valve regulator change for ease of convertibility.
• 3 amp fuse protection against low voltage shorts:Protects transformer and control board.
• Low voltage terminal board: For easy field wiring.
• Easy open pawl latch: Secures the door firmly for transit, yet allows easy removal for access.
• Appliance quality door: Protects against rust and other corrosion. Baked enamel finish allows for easy cleaning.
• Fully insulated cabinet: Insures minimized heat loss and quiet operation.
• Color coded wire harness:Designed to fit the components, all with quick-connect fittings for ease of service and replacement.
• Multi-speed direct drive blower:Designed to give a wide range of cooling capacities. Switches on PCB, provide ultra easy motor speed selection. 40VA transformer included.
• 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.
