Disconnect the hoses from the trap assembly, and remove trap and trap mounting bracket from the blower compartment. Using cover plate and gasket provided in the loose parts bag, cover the hole from the burner compartment to the blower compartment and secure with screws.
Remove knockout from the side of the furnace casing where drain tube will exit.
Mount the trap externally to the bottom side of the unit using the two screws provided in the location shown.
Cut the corrugated tube as shown in the illustration above. Connect the corrugated hose from the transition to the trap. Secure connections with clamps.
Remove the black 1/2″ (12.7mm) ID drain tube from the drain tee. Install a yellow cap and clamp over the open drain port of the drain tee.
Connect the black 1/2″ (12.7mm) ID drain tube from the Vent Drain to the trap. Secure connections with clamps.
Connect the 3/16″ (4.8mm) ID relief tube to the middle port on the trap. If an extension is required, use the 3/16″ (4.8mm) OD flexible tubing connector and the black 3/16″ (4.8mm) ID relief tube in the loose parts bag. Cut tube to length. Secure all connections with clamps.
Cut an appropriate length of 2″ (50.8mm) PVC pipe, long enough to exit the cabinet and connect the vent drain to either:
SA 2″ (50.8mm) PVC coupling fastened onto the drain tee Install tee trap into bottom section of tee and glue pipe.
Connect the tee trap and the main drain line exiting the casing as shown in Fig. 16.
NOTE: It is recommended that all PVC piping and fitting connections be fit up and inspected before final cementing. Both the external trap and the external tee trap must be primed before operation. Verify all condensate drain connections are securely clamped. A coupling and clamps (in loose part bag) may be installed as shown for future servicing of the vent system.
