Fig. 10—Horizontal Left Tube Configuration

a.Remove factory-installed cap and clamp from LOWER inducer housing drain connection.

b.Remove and discard UPPER (molded) inducer housing drain tube which was previously connected to conden- sate trap.

c.Install cap and clamp on UPPER inducer housing drain connection where molded drain tube was removed.

d.Use inducer housing drain tube (violet label and factory- supplied in loose parts bag) to connect LOWER inducer housing drain connection to the condensate trap.

e.Connect inducer housing drain connection to condensate trap.

(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) directly from inducer housing to condensate trap as shown in Fig. 9.

(b.) Determine appropriate length and cut.

(c.) Connect tube to condensate trap.

(d.) Clamp tube to prevent any condensate leakage.

3.Relief Port Tube

Refer to Pressure Switch Tubing section for connection procedure.

C.Condensate Trap Field Drain Attachment

Refer to Condensate Drain section for recommendations and procedures.

D. Pressure Switch Tubing

One collector box pressure tube (pink label) is factory connected to the pressure switch for use when furnace is installed in UPFLOW applications. This tube MUST be disconnected and used for the condensate trap relief port tube. The other collector box pressure tube (green label) which was factory connected to the condensate trap relief port connection MUST be connected to the pressure switch in DOWNFLOW or HORIZONTAL RIGHT applications.

NOTE: See Fig. 8 or 9 or tube routing label on main furnace door to check for proper connections.

Relocate tubes as described below.

1.Disconnect collector box pressure tube (pink label) attached to pressure switch.

2.Extend collector box pressure tube (green label) which was previously connected to condensate trap relief port connec- tion by splicing to small diameter tube (factory-supplied in loose parts bag).

3.Connect collector box pressure tube (green label) to pres- sure switch connection labeled COLLECTOR BOX.

4.Extend collector box pressure tube (pink label) which was previously connected to pressure switch by splicing to remaining small diameter tube (factory-supplied in loose parts bag).

5.Route this extended tube (pink label) to condensate trap relief port connection.

6.Determine appropriate length, cut, and connect tube.

7.Clamp tube to relief port connection.

E. Condensate Trap Freeze Protection
