Downflow Right-Side Vent and Trap (See Fig. 15)

Remove the drain tee if installed.

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.

Move the caps to the top of the trap and mount the trap externally to the right side of the unit using the two(2) screws provided.

Connect the corrugated drain tube from the transition box to the trap as shown. If an extension is required, use the black PVC tube connector and the black 5/8″ (15.9mm) ID drain tube in the loose parts bag. Cut tube to length. Secure all connections with clamps.

Connect the drain hose from the Vent Drain to the trap. If an extension is required, use the black 1/2″ (12.7mm) OD barbed coupling, connect a black 1/2″ (12.7mm) ID elbow tube and a suitable section of a 1/2″ (12.7mm) ID drain tube to make connection from the vent drain to the trap. Secure all connections with clamps.

Install the vent pipe grommet into the casing

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.

Remove knockout from the side of the furnace casing where drain tube will exit.

Connect the tee trap and the main drain line exiting the casing as shown in Fig. 15.

NOTE: 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.
