d. Use inducer housing drain tube (violet label and factory-supplied in loose parts bag) to connect LOWER inducerhousing drain connection to the condensate trap.e. Connect inducer housing drain connection to condensatetrap.(1.) Condensate Trap Located on Left Side of Casing(a.) Determine appropriate length and cut.(b.) Connect tube to condensate trap.(c.) Clamp tube to prevent any condensate leakage.(2.) Condensate Trap Located on Right Side of Casing(a.) Route inducer housing drain tube (violet label)between gas valve and inlet housing behind col-lector box drain tube.(b.) Determine appropriate length and cut.(c.) Connect tube to condensate trap.(d.) 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. 7 or 8 or tube routing label on main furnace doorto check for proper connections.Relocate tubes as described below.1. Disconnect collector box pressure tube (pink label) attached topressure switch.2. Use small diameter tube (factory-supplied in loose parts bag)to extend collector box pressure tube (green label) which waspreviously connected to condensate trap relief port connec-tion.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.Step 4—Horizontal Left (Supply-Air Discharge)ApplicationsA horizontal left furnace application is where furnace blower islocated to the right of combustion and controls section of furnaceand conditioned air is discharged to the left.Local codes may require a drain pan under entire furnace andcondensate trap when a condensing furnace is used in an atticapplication or over a finished ceiling.NOTE: In Canada, installations shall be in accordance withcurrent NSCNGPIC and/or local codes.NOTE: The auxiliary junction box (J-box) MUST be relocated toopposite side of furnace casing. (See Fig. 9.) See ElectricalConnection section for J-box relocation.CONDENSATE TRAP LOCATIONThe condensate trap must be removed from the factory-installedblower shelf location and relocated in selected application locationas shown in Fig. 2 or 9.To relocate condensate trap from the blower shelf to desiredlocation, perform the following:1. Remove 3 tubes connected to condensate trap.2. Remove trap from blower shelf by gently pushing tabs inwardand rotating trap.3. Remove casing hole filler cap from casing hole. (See Fig. 2 or9.)4. Install casing hole filler cap into blower shelf hole where trapwas removed.5. Install condensate trap into casing hole by inserting tubeconnection stubs through casing hole and rotating until tabssnap into locking position.CONDENSATE TRAP TUBINGNOTE: See Fig. 9 or tube routing label on main furnace door tocheck for proper connections.1. Collector Box Drain Tubea. Install drain tube coupling (factory-supplied in loose partsbag) into collector box drain tube (blue label) which waspreviously connected to condensate trap.b. Connect large diameter drain tube and clamp (factory-supplied in loose parts bag) to drain tube coupling, extend-ing collector box drain tube.c. Route extended tube (blue label) to condensate trap and cutto appropriate length.d. Clamp tube to prevent any condensate leakage.2. Inducer Housing Drain Tubea. Remove and discard LOWER (molded) inducer housingdrain tube which was previously connected to condensatetrap.b. Use inducer housing drain extension tube (violet label andfactory-supplied in loose parts bag) to connect LOWERinducer housing drain connection to the condensate trap.c. Determine appropriate length, cut, and connect tube.d. Clamp tube to prevent any condensate leakage.3. Relief Port Tubea. Use small diameter tube (factory-supplied in loose partsbag) to extend collector box tube (green label) which waspreviously connected to the condensate trap.b. Route extended collector box pressure tube to relief portconnection on the condensate trap.c. Determine appropriate length, cut, and connect tube.d. Clamp tube to prevent any condensate leakage.8
