NOTE: See Fig. 7 or 8 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.

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.
