TECHNICAL SPECIFICATIONS KG7SD with ECM High Efficiency, Single Stage Condensing, Upflow/Horizontal Gas Furnace Models Up to 95% AFUE 38,000 - 120,000 Btuh Input The high efficiency upflow gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. Upflow/horizontal units come ready for upflow or horizontal application.The extended flush jacket provides a pleasing "appliance appearance." Design certified by CSA for application in Canada and the United States. FEATURES and BENEFITS · iSEER: 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 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 ECM blowers. · 16 speeds for heating and cooling enables flexible airflow. · 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. · 90 second fixed cooling cycle blower-off delay (TDR) increases cooling performance when matched with a Nortek Global HVAC coil. · 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. · 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.
