c. Determine appropriate length, cut, and connect tube.d. Clamp tube to prevent any condensate leakage.CONDENSATE TRAP FIELD DRAIN ATTACHMENTSRefer to Condensate Drain section for recommendations andprocedures.PRESSURE SWITCH TUBINGThe LOWER collector box pressure tube (pink label) is factoryconnected to the pressure switch for use when furnace is installedin UPFLOW applications. This tube MUST be disconnected,extended, rerouted, and then reconnected to the pressure switch inHORIZONTAL LEFT applications.NOTE: See Fig. 10 or tube routing label on main furnace door tocheck for proper connections.Modify tube as described below.1. Disconnect collector box pressure tube (pink label) attached topressure switch.2. Use smaller diameter tube (factory-supplied in loose partsbag) to extend tube disconnected in item 1.3. Route extended tube:a. Behind inducer housing.b. Between blower shelf and inducer housing.c. Behind inducer motor bracket.d. Between inducer motor and pressure switch.4. Determine appropriate length, cut, and reconnect tube topressure switch connection labeled COLLECTOR BOX.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 11 or 12.)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: Combustion-air and vent pipes are restricted to a mini-mum length of 5 ft. (See Table 11.)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. 11, 12 or 38.)Step 5—Horizontal Right (Supply-Air Discharge)ApplicationsA horizontal right furnace application is where furnace blower islocated to the left of combustion and controls section of furnace,and conditioned air is discharged to the right.Fig. 10—Horizontal Left Tube ConfigurationA00215CONDENSATETRAPAUXILIARY "J" BOXPLUGCAPINDUCER HOUSINGDRAIN TUBE (VIOLET)COLLECTOR BOXDRAIN TUBE (BLUE)COLLECTOR BOX TUBE (PINK)RELOCATE TUBE BETWEEN BLOWER SHELF AND INDUCER HOUSING FOR040, 060, AND 080 HEATING INPUT FURNACESCOLLECTOR BOXEXTENSION TUBECOLLECTOR BOXDRAIN TUBE(BLUE AND WHITE STRIPED)DRAIN TUBE COUPLINGCOLLECTOR BOXTUBE (GREEN)COLLECTORBOX EXTENSIONDRAIN TUBE11
