3 12 YEAR ALL PARTS WARRANTY This product offers a 1-Year Dependability Promise to replace the unit if the heat exchanger fails within the first year of operation, to the original owner. Product registration required for 12-year All Parts Warranty and Dependability Promise within a limited period of time after the installation. See current warranty document for details. This can be viewed at or ask your sales representative. Also when registered, this product is upgraded to a limited lifetime heat exchanger warranty. The high efficiency gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. The rounded corner jacket provides a pleasing appliance appearance. Design certified by CSA for Canada and the United States. 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. - 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 assures a long life 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) second post purge: Increases life of heat exchanger. - Hot surface igniter: Innovative application of an appliance type igniter with a 20 year history of reliability. Utilizes proven SmartStart 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 second cooling cycle blower-off delay (TDR) : increases cooling performance when matched with a NORDYNE coil. - Flexible category I venting system: May be vented with dedicated venting system or common vented with other category one appliances. - High efficiency blower kits: Maximize efficiencies. On select units, a SEER improvement of up to 1 point is realized. - Multi-speed direct drive blower: Designed to give a wide range of cooling capacities. Switches on PCB, provide ultra easy motor speed selection. - LP convertible: Simple burner orifice 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 flashes. - Integrated control board: Incorporates connections for electronic air cleaner and humidifier. - Two piece door design: Enhances furnace appearance and uses captured screws to prevent loosing door screws. - Blower Compartment: Insulated for ultra quiet operation. 3
