FIRE, INJURY OR DEATH HAZARDFailure to follow this warning could result in electrical shock,fire, personal injury or death.Casing hole filler cap must be installed in blower shelf holewhen condensate trap is relocated.4. Install condensate trap into right-hand side casing hole byinserting tube connection stubs through casing hole androtating until tabs snap into locking position.5. Fill unused condensate trap casing holes with plastic fillercaps (factory-supplied in loose parts bag).CONDENSATE TRAP TUBINGNOTE: See Fig. 10 or tube routing label on main furnace door tocheck for proper connections.1. Collector Box Drain Tubea. Remove factory-installed plug from LOWER collector boxdrain tube (blue and white striped label).b. Install removed clamp and plug into UPPER collector boxdrain tube (blue label) which was previously connected tocondensate trap.c. Connect LOWER collector box drain tube (blue and whitestriped label) to condensate trap. Tube does not need to becut.d. Clamp tube to prevent any condensate leakage.2. Inducer Housing Drain Tubea. Remove factory-installed cap and clamp from LOWERinducer housing drain connection.b. Remove and discard UPPER (molded) inducer housingdrain tube which was previously connected to condensatetrap.c. Install cap and clamp on UPPER inducer housing drainconnection where molded drain tube was removed.d. Use inducer housing drain extension tube (violet label andfactory-supplied in loose parts bag) to connect LOWERinducer housing drain connection to condensate trap.e. Determine appropriate length, cut, and connect tube tocondensate trap.f. Clamp tube to prevent any condensate leakage.3. Relief Port TubeRefer to Pressure Switch Tubing section for connectionprocedure.CONDENSATE TRAP FIELD DRAIN ATTACHMENTRefer to Condensate Drain section for recommendations andprocedures.PRESSURE SWITCH TUBINGOne collector box pressure tube (pink label) is factory connected tothe pressure switch for use when furnace is installed in UPFLOWor HORIZONTAL LEFT applications. This tube MUST be dis-connected and used for the condensate trap relief port tube. Theother collector box pressure tube (green label) which was factoryconnected to the condensate trap relief port connection MUST beconnected to the pressure switch in DOWNFLOW or HORIZON-TAL RIGHT applications.NOTE: See Fig. 10 or tube routing label on main furnace door tocheck for proper connections.Relocate tubes as described below.1. Disconnect collector box pressure tube (pink label) attached topressure switch.2. Extend collector box pressure tube (green label) which waspreviously connected to condensate trap relief port connectionby splicing to small diameter tube (factory-supplied in looseparts bag).3. Connect collector box pressure tube (green label) to pressureswitch connection labeled COLLECTOR BOX.4. Use remaining small diameter tube (factory-supplied in looseparts bag) to extend collector box pressure tube (pink label)which was previously connected to pressure switch.5. Route this extended tube (pink label) to condensate trap reliefport connection.6. Determine appropriate length, cut, and connect tube.7. Clamp tube to relief port connection.CONDENSATE TRAP FREEZE PROTECTIONRefer to Condensate Drain Protection section for recommenda-tions and procedures.CONSTRUCT A WORKING PLATFORMConstruct working platform where all required furnace clearancesare met. (See Fig. 3 and 9.)UNIT MAY NOT OPERATEFailure to follow this caution may result in intermittent unitoperation.The condensate trap MUST be installed below furnace. SeeFig. 5 for dimensions. The drain connection to condensatetrap must also be properly sloped to an open drain.NOTE: Vent pipes are restricted to a minimum length of 5 ft. (SeeTable 7.)NOTE: A 12-in. minimum offset pipe section is recommendedwith short (5 to 8 ft) vent systems. This recommendation is toreduce excessive condensate droplets from exiting the vent pipe.(See Fig. 9 or 29.)LOCATIONStep 1—GeneralThis furnace must• be installed so the electrical components are protected fromwater.• not be installed directly on any combustible material other thanwood flooring (refer to SAFETY CONSIDERATIONS).• be located so vent pipe maximum lengths are not exceeded.Refer to Table 7.• be located where available electric power and gas supplies meetspecifications on the furnace rating plate.• be attached to an air distribution system and be located as closeto the center of the distribution system as possible. Refer to AirDucts section.• be provided with ample space for servicing and cleaning.Always comply with minimum fire protection clearancesshown on the furnace clearance-to-combustibles label. (SeeFig. 3.)This furnace may be located in a confined space without specialprovisions for dilution or ventilation air.When a furnace is installed so that supply ducts carry air circulatedby the furnace to areas outside the space containing the furnace,the return air shall also be handled by ducts sealed to furnacecasing. The ducts terminate outside the space containing thefurnace to ensure there will not be a negative pressure conditionwithin equipment room or space.11
