desired furnace side for field drain attachment. See Condensate Trap Tubing
B.Condensate Trap Tubing (Factory-Shipped Orientation)
NOTE: See Fig. 6 or tube routing label on main furnace door to confirm location of these tubes.
1.Collector Box Drain, Inducer Housing Drain, Relief Port, and Pressure Switch Tubes
These tubes should be factory attached to condensate trap and pressure switch ready for use in UPFLOW applications. These tubes can be identified by their connection location and also by a color label on each tube. These tubes are identified as follows: collector box drain tube (blue label), inducer housing drain tube (violet label or molded), relief port tube (green label), and pressure switch tube (pink label).
2.Condensate Trap Drain Tube
The condensate trap drain connection must be extended for field attachment by doing the following:
a.Determine location of field drain connection. (See Fig. 2 or 6.)
NOTE: If internal filter is used, drain tube should be located to opposite side of casing from return duct attachment to assist in filter removal.
b.Remove and discard casing drain hole plug button from desired side.
c.Install drain tube coupling grommet
d.Slide drain tube coupling
e.Cement 2
NOTE: Failure to use CPVC elbows may allow drain to kink and prevent draining.
f.Connect larger diameter drain tube and clamp (factory- supplied in loose parts bag) to condensate trap and clamp securely.
g.Route tube to coupling and cut to appropriate length.
h.Attach tube to coupling and clamp securely.
C.Condensate Trap Location (Alternate Upflow Orientation)
An alternate location for the condensate trap is the
NOTE: If the alternate
To relocate condensate trap to the
1.Remove 3 tubes connected to condensate trap.
2.Remove trap from blower shelf by gently pushing tabs inward and rotating trap.
3.Install casing hole filler cap
WARNING: Casing hole filler cap must be installed in blower shelf hole when condensate trap is relocated. Failure to follow this warning could result in electrical shock, fire, personal injury or death.
4.Install condensate trap into
5.Fill unused condensate trap casing holes with plastic filler caps
D.Condensate Trap Tubing (Alternate Upflow Orientation)
NOTE: See Fig. 7 or tube routing label on main furnace door to confirm location of these tubes.
1. Collector Box Drain Tube
Connect collector box drain tube (blue label) to condensate trap.
NOTE: On
2.Inducer Housing Drain Tube
a.Remove and discard LOWER (molded) inducer housing drain tube which was previously connected to conden- sate trap.
b.Use inducer housing drain extension tube (violet label and
c.Determine appropriate length, cut, and connect tube.
d.Clamp tube to prevent any condensate leakage.
3.Relief Port Tube
a.Connect relief port tube (green label) to condensate trap.
b.Extend this tube (if required) by splicing to small diameter tube
c.Determine appropriate length, cut, and connect tube.
E. Condensate Trap Field Drain Attachment
Refer to Condensate Drain section for recommendations and procedures.
F. Pressure Switch Tubing
The LOWER collector box pressure tube (pink label) is factory connected to the pressure switch and should not require any modification.
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door to check for proper connections.
G.Upper Collector Box and Inducer Housing (Unused) Drain Connections
UPPER COLLECTOR BOX DRAIN CONNECTION
Attached to the UPPER collector box drain connection is a
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door to check for proper connections.
UPPER INDUCER HOUSING DRAIN CONNECTION
Attached to the UPPER (unused) inducer housing drain connection is a cap and clamp. This cap is used to prevent condensate leakage in this application. Ensure this connection is capped.
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door to check for proper connections.
