5. Fill unused condensate trap casing holes with plastic filler
caps (factory-supplied in loose parts bag).
CONDENSATE TRAP TUBING
NOTE:
See Fig. 8 or 9 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 connected to condensate
trap.
c. Connect LOWER collector box drain connection to con-
densate trap.
(1.) Condensate Trap Located on Left Side of Casing
(a.) Connect LOWER collector box drain tube (blue
and white striped label) to condensate trap. Tube
does not need to be cut.
(b.) Clamp tube to prevent any condensate leakage.
(2.) Condensate Trap Located on Right Side of Casing
(a.) Install drain tube coupling (factory-supplied in
loose parts bag) into collector box drain tube
(blue and white striped label) which was previ-
ously plugged.
(b.) Connect larger diameter drain tube (factory-
supplied in loose parts bag) to drain tube cou-
pling, extending collector box drain tube for
connection to condensate trap.
(c.) Route extended collector box drain tube between
gas valve and inlet housing as shown in Fig. 9.
(d.) Determine appropriate length and cut.
(e.) Connect to condensate trap.
(f.) 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 condensate
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)
between gas valve and inlet housing behind col-
lector box drain tube.
(b.) Determine appropriate length and cut.
(c.) Connect tube to condensate trap.
(d.) Clamp tube to prevent any condensate leakage.
