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, 7, or 8.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, 7,or 8.)4. Install casing hole filler cap into blower shelf hole where trapwas removed.5. Install condensate trap into desired casing hole by insertingtube connection stubs through casing hole and rotating untiltabs snap into locking position.CONDENSATE TRAP TUBINGNOTE: See Fig. 7 or 8 or tube routing label on main furnace doorto check 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 connected to condensatetrap.c. Connect LOWER collector box drain connection to con-densate trap.(1.) Condensate Trap Located on Left Side of Casing(a.) Connect LOWER collector box drain tube (blueand white striped label) to condensate trap. Tubedoes not need to be cut.(b.) Clamp tube to prevent any condensate leakage.(2.) Condensate Trap Located on Right Side of Casing(a.) Install drain tube coupling (factory-supplied inloose parts bag) into collector box drain tube(blue and white striped label) which was previ-ously plugged.(b.) Connect larger diameter drain tube (factory-supplied in loose parts bag) to drain tube cou-pling, extending collector box drain tube forconnection to condensate trap.(c.) Route extended collector box drain tube betweengas valve and inlet housing as shown in Fig. 8.(d.) Determine appropriate length and cut.(e.) Connect to condensate trap.(f.) 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.Fig. 7—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. 8—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)CAP7
