TECHNICALSPECIFICATIONSFG6T(C,L) SeriesHigh Efficiency / Direct Vent or Non Direct Vent2-Stage Condensing Gas Furnace with Variable Speed Blower92 Upflow/Horizontal90 DownflowThe high efficiency 2-Stage gas furnace may beinstalled free standing in a utility room, basement,or enclosed in an alcove or closet. The upflowmodel converts easily to horizontal application. Theextended flush jacket provides a pleasing “applianceappearance.” Design certified by CSA International(Canadian Standards res and Benefits Best warranty in the business –– A lifetime warranty on the heat exchanger– 8 Year Limited Parts and 5 Year Quality Pledge 100% fired and tested – All units and each component(both mechanical and electrical) are tested on themanufacturing line. Best packaging in the industry – Unique design assuresproduct will arrive to the homeowner dent free. Clean, quiet, and efficient operation – Due to theunique design of in-shot burners, location of inducer,use of insulation, and operating at low fire using lessfuel than single capacity furnaces. Fixed 30 second blower delay at burner start-up assuresa warm duct temperature at furnace start-up. Fixed 30-second inducer post purge increases life ofheat exchanger. Dependable, hot surface ignitor – Innovative applicationof an appliance type ignitor with a 20-year history ofreliability, assures no call-backs because of handling. Color coded wire harness – Designed to fit thecomponents, all with quick-connect fittings for ease ofservice and replacement. Reliable heat exchanger – Aluminized primary andstainless steel secondary heat exchanger assures longlife. 40-second fixed cooling cycle blower-off delay (TDR)increases cooling performance when matched with aNORDYNE coil. Approved for direct vent and non direct vent furnace,category IV venting system – May be vertically or horizontally vented using either a one-pipe or two-pipesystem for maximum flexibility in installation.Variable speed blower included to maximize airconditioner and heat pump efficiencies. On selectedunits, SEER ratings up to 16 and HSPF ratings up to8.5 are ARI listed.LP convertible – Simple burner orifice and regulatorspring change for ease of convertibility.Factory installed drain system – for reliableperformance.Diagnostic light flashes identify limit failure, pressureswitch failure and improper ground and polarization– for easy troubleshooting.Incorporates integrated control board with connectionsfor electronic air cleaner, humidifier and twinning.Two piece door design enhances furnace appearanceand uses screw fasteners for great fit and accessibility.3 amp fuse protection against low voltage shorts; protectstransformer and control board.Low voltage terminal board for easy field wiring.
