LOW 350 cfm/ton is recommended for variable speed application for COMFORT & HUMIDCLIMATE setting; NORMAL is 400 cfm/ton; HIGH 450 cfm/ton is for DRY CLIMATE setting.NOTE:CONTINUOUS fan mode during COOLING operationmay not be appropriate in humid climates. Ifthe indoor air exceeds 60% relative humidity orsimply feels uncomfortably humid, it is recommendedthat the fan only be used in the AUTOmode.
Airflow AdjustmentCheck inlet and outlet air temperatures to make sure theyare within the range specified on the Furnace rating nameplate.If the airflow needs to be increased or decreased,see the Airflow Label on the Furnace or the unit’s ServiceFacts for information on changing the speed of the BlowerMotor for your specific model. Blower speed changes aremade on the User Interface.INDOOR BLOWER TIMINGHeating: The Integrated Furnace <strong>Co</strong>ntrol module controlsthe Indoor Blower. The Blower start is fixed at 45 secondsafter ignition. The FAN-OFF period is field selectable by theUser Interface at 60, 100, 140, or 180 seconds. The factorysetting is 100 seconds.MODELTYPERATINGS 240% (low) heat Input BTUH40% (low) heat Capacity BTUH (ICS) 3100% (high) heat Input BTUH100% (high) heat Capacity BTUH (ICS) 3Temp. rise (Min.-Max.) °F.AFUEBLOWER DRIVEDiameter - Width (In.)No. UsedSpeeds (No.)CFM vs. in. w.g.Motor HPR.P.M.Volts / Ph / HzCOMBUSTION FAN - TypeDrive - No. SpeedsMotor HP - RPMVolts / Ph / HzFLAFILTER — Furnished?Type RecommendedHi Vel.

Mechanical SpecificationsMODULATING OPERATIONThe modulating gas valve provideslonger heating cycles for more consistentheating comfort. Modulates from40% to 100% of the normal firing ratesin less than 1% increments of the furnace'sheating capacity saving energy,while at the same time providing maximumhomeowner comfort.COMMUNICATING MODEFurnace is shipped ready to be connectedin communicating mode usingthree wire hook-up using ACONT900comfort control.ALTERNATE 24V MODEFurnace is field cofigurable to 24Vnon-communicating mode.COMFORT CONTROLAcculink II TM <strong>Co</strong>mmunicating furnacedesign, offers plug and play – walkaway installation. Assures the entireheating and air conditioning systemis set up in the proper modes to optimizethe engineered performance ofthe matched system installed. Thefurnace can also be connected in24V mode.NATURAL GAS MODELSCentral Heating furnace designs arecertified by the American Gas Associationfor both natural and L.P. gas. Limitsetting and rating data were establishedand approved under standardrating conditions using American NationalStandards Institute standards.SAFE OPERATIONThe Integrated System <strong>Co</strong>ntrol hassolid state devices, which continuouslymonitor for presence of flame, whenthe system is in the heating mode ofoperation. Dual solenoid combinationgas valve and regulator provide additionalsafety.QUICK HEATINGDurable, cycle tested, heavy gaugealuminized steel heat exchanger quicklytransfers heat to provide warmconditioned air to the structure. Lowenergy power vent blower, to increaseefficiency and provide a positive dischargeof gas fumes to the outside.BURNERSMulti-port In-shot burners will giveyears of quiet and efficient service. Allmodels can be converted to L.P. gaswithout changing burners.INTEGRATED SYSTEM CONTROLExclusively designed operational programprovides total control of furnacelimit sensors, blowers, gas valve,flame control and includes self diagnosticsfor ease of service. Alsocontains connection points for EACand Humidifier.AIR DELIVERYThe variable speed blower motor hassufficient airflow for most heating andcooling requirements and will switchfrom heating to cooling speeds on demandfrom room thermostat. Theblower door safety switch will preventor terminate furnace operation whenthe blower door is removed.SECONDARY HEAT EXCHANGERThe Freedom 95 has a special type29-4C stainless steel secondaryheat exchanger to reclaim heat fromflue gases which would normally belost.STYLINGHeavy gauge steel and “wrap-around”cabinet construction is used in the cabinetwith baked-on enamel finish forstrength and beauty. The heat exchangersection of the cabinet is completelylined with foil faced fiberglass insulation.This results in quiet and efficient operationdue to the excellent acoustical andinsulating qualities of fiberglass. Built-inbottom pan and alternate bottom, left orright side return air connection provision.FEATURES AND GENERALOPERATIONThe Freedom 95 High Efficiency GasFurnaces utilize an Adaptive Heat UpSilicon Nitride Hot Surface Ignition system,which eliminates the waste of aconstant burning pilot.
