a. Install drain tube coupling (factory-supplied in loose parts bag) into collector box drain tube (blue label) which was previously connected
to condensate trap.
b. Connect large diameter drain tube and clamp (factory-supplied in loose parts bag) to drain tube coupling, extending collector box drain
tube.
c. Route extended tube (blue label) to condensate trap and cut to appropriate length.
d. Clamp tube to prevent any condensate leakage.
2. Inducer Housing Drain Tube
a. Remove and discard LOWER (molded) inducer housing drain tube which was previously connected to condensate trap.
b. Use inducer housing drain extension tube (violet label and factory-supplied in loose parts bag) to connect LOWER inducer housing drain
connection to the condensate trap.
c. Determine appropriate length, cut, and connect tube.
d. Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
a. Extend collector box tube (green label) which was previously connected to the condensate trap by splicing to small diameter tube
(factory-supplied in loose parts bag).
b. Route extended collector box pressure tube to relief port connection on the condensate trap.
c. Determine appropriate length, cut, and connect tube.
d. Clamp tube to prevent any condensate leakage.
C. Condensate Trap Field Drain Attachments
Refer to Condensate Drain section for recommendations and procedures.
D. 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. 9 or tube routing label on main furnace door to check for proper connections.
E. Condensate Trap Freeze Protection
Refer to Condensate Drain Protection section for recommendations and procedures.
F. Construct a Working Platform
Construct working platform where all required furnace clearances are met. (See Fig. 3 and 10.)
