b. Use inducer housing drain extension tube (violet label andfactory-supplied in loose parts bag) to connect LOWERinducer housing drain connection to condensate trap.c. Determine appropriate length, then cut and connect tube.d. Clamp tube to prevent any condensate leakage.3. Relief Port Tubea. Connect relief port tube (green label) to condensate trap.b. Extend this tube (if required) by splicing to small diametertube (factory-supplied in loose parts bag).c. Determine appropriate length, then cut and connect tube.CONDENSATE TRAP FIELD DRAIN ATTACHMENTRefer to Condensate Drain section for recommendations andprocedures.PRESSURE SWITCH TUBINGThe LOWER collector box pressure tube (pink label) is factoryconnected to the pressure switch and should not require anymodification.NOTE: See Fig. 7 or 8 or tube routing label on main furnace doorto check for proper connections.UPPER COLLECTOR BOX AND INDUCER HOUSING(UNUSED) DRAIN CONNECTIONSUpper Collector Box Drain ConnectionAttached to the UPPER collector box drain connection is afactory-installed corrugated, plugged tube (blue and white stripedlabel). This tube is plugged to prevent condensate leakage in thisapplication. Ensure this tube is plugged.NOTE: See Fig. 7 or 8 or tube routing label on main furnace doorto check for proper connections.Upper Inducer Housing Drain ConnectionAttached to the UPPER (unused) inducer housing drain connectionis a cap and clamp. This cap is used to prevent condensate leakagein this application. Ensure this connection is capped.NOTE: See Fig. 7 or 8 or tube routing label on main furnace doorto check for proper connections.CONDENSATE TRAP FREEZE PROTECTIONRefer to Condensate Drain Protection section for recommenda-tions and procedures.Step 3—Downflow ApplicationsA downflow furnace application is where furnace blower is locatedabove combustion and controls section of furnace, and conditionedair is discharged downwards.CONDENSATE TRAP LOCATIONThe condensate trap must be removed from the factory-installedblower shelf location and relocated in selected application locationas shown in Fig. 2, 9, or 10.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. 2and 10.)4. Install casing hole filler cap (factory-supplied in loose partsbag) into blower shelf hole where trap was removed.Fig. 9—Downflow Tube Configuration(Left-Hand Trap Installation)A94215PLUGCOLLECTOR BOXTUBE (GREEN)COLLECTOR BOXTUBE (PINK)COLLECTOR BOXDRAIN TUBE (BLUE& WHITE STRIPED)COLLECTOR BOXEXTENSION TUBECONDENSATETRAPINDUCER HOUSINGDRAIN TUBE (VIOLET)CAPCOLLECTOR BOXDRAIN TUBE (BLUE)Fig. 10—Downflow Tube Configuration(Right-Hand Trap Installation)A94216PLUGCOLLECTOR BOXTUBE (GREEN)COLLECTOR BOXTUBE (PINK)COLLECTOR BOXDRAIN TUBE (BLUE& WHITE STRIPED)COLLECTOR BOXEXTENSIONDRAIN TUBECONDENSATETRAPINDUCER HOUSINGDRAIN TUBE(VIOLET)COLLECTOR BOXEXTENSION TUBEDRAIN TUBECOUPLINGCOLLECTOR BOXDRAIN TUBE (BLUE)CAP8
