All drainand pressure tubes are connected as shown in Fig. 6. Seeappropriate application instructions for these procedures.Step 2 -- Upflow ApplicationsAn upflow furnace application is where furnace blower is locatedbelow combustion and controls section of furnace, andconditioned air is discharged upwards.COLLECTOR BOXTUBE (PINK)CONDENSATETRAPCOLLECTOR BOXTUBE (GREEN)COLLECTOR BOXDRAIN TUBE (BLUE)INDUCERHOUSINGDRAIN TUBE(VIOLET)CAPCOLLECTOR BOXDRAIN TUBE (BLUE& WHITE STRIPED)PLUGA00289Fig. 7 -- Alternate Upflow Tube Configuration andTrap LocationCONDENSATE TRAP LOCATION(FACTORY-SHIPPED ORIENTATION)The condensate trap is factory installed in the blower shelf andfactory connected for UPFLOW applications. A factory-suppliedtube is used to extend the condensate trap drain connection to thedesired furnace side for field drain attachment. See CondensateTrap Tubing (Factory-Shipped Orientation) section for drain tubeextension details. (See Fig. 5.)CONDENSATE TRAP TUBING(FACTORY-SHIPPED ORIENTATION)NOTE: See Fig. 6 or tube routing label on main furnace door toconfirm location of these tubes.1. Collector Box Drain, Inducer Housing Drain, Relief Port,and Pressure Switch TubesThese tubes should be factory attached to condensate trapand pressure switch ready for use in UPFLOWapplications. These tubes can be identified by theirconnection location and also by a color label on each tube.These tubes are identified as follows: collector box draintube (blue label), inducer housing drain tube (violet labelor molded), relief port tube (green label), and pressureswitch tube (pink label).2. Condensate Trap Drain TubeThe condensate trap drain connection must be extendedfor field attachment by doing the following:f. Determine location of field drain connection. (SeeFig. 2 or 6.)NOTE: If internal filter is used, drain tube should be located toopposite side of casing from return duct attachment to assist infilter removal.g. Remove and discard casing drain hole plug buttonfrom desired side.58MCB
