remaining small diameter tube (factory-supplied in loose parts bag).
5. Route this extended tube (pink label) to condensate trap relief port connection.
6. Determine appropriate length, cut, and connect tube.
7. Clamp tube to relief port connection.
CONDENSATE TRAP FREEZE PROTECTION
Refer to Condensate Drain Protection section for recommendations and procedures.
Step 4—Horizontal Left (Supply-Air Discharge)
Applications
In a horizontal left furnace application, the blower is located to the right of the burner section, and conditioned air is discharged to the left.
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 (factory-supplied in loose parts bag) into blower shelf hole where trap was removed.
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 left-hand side casing hole by inserting tube connection stubs through casing hole and rotating until tabs snap into locking position.
5. Fill unused condensate trap casing holes with plastic filler caps (factory-supplied in loose parts bag).
Local codes may require a drain pan under entire furnace and condensate trap when a condensing furnace is used in an attic application or over a finished ceiling.
NOTE: In Canada, installations shall be in accordance with current NSCNGPIC and/or local codes.
CONDENSATE TRAP LOCATION
The condensate trap must be removed from the factory-installed blower shelf location and relocated in selected application location as shown in Fig. 2 or 10.
To relocate condensate trap from the blower shelf to desired location, perform the following:
CONDENSATE TRAP TUBING
NOTE: See Fig. 10 or tube routing label on main furnace door to check for proper connections.
1. Collector Box Drain Tube 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 (factorysupplied in loose parts bag) to drain tube coupling, extending collector box drain tube.
