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 condens-
ate trap.
c. Determine appropriate length, then 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 diamet-
