NOTE: See Fig. 11 or tube routing label on main furnace door to check for proper connections.

1.Collector Box Drain Tube

a.Remove factory-installed plug from LOWER collector box drain tube (blue and white striped label).

b.Install removed clamp and plug into UPPER collector box drain tube (blue label) which was previously con- nected to condensate trap.

c.Connect LOWER collector box drain tube (blue and white striped label) to condensate trap. Tube does not need to be cut.

d.Clamp tube to prevent any condensate leakage.

2.Inducer Housing Drain Tube

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 extension tube (violet label and factory-supplied in loose parts bag) to connect LOWER inducer housing drain connection to conden- sate trap.

e.Determine appropriate length, cut, and connect tube to condensate trap.

f.Clamp tube to prevent any condensate leakage.

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 or HORIZONTAL LEFT applications. This tube MUST be dis- connected 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 HORIZON- TAL RIGHT applications.

NOTE: See Fig. 11 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.Use remaining small diameter tube (factory-supplied in loose parts bag) to extend collector box pressure tube (pink label) which was previously connected to pressure switch.
