Downflow Left-Side Vent and Trap (See Fig. 14).
Remove the inducer mounting screws, rotate the inducer 180° and retighten the inducer screws to 20″ pounds torque.
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 left side of the unit using the two(2) screws provided.
Cut the 5/8″ (15.9mm) ID corrugated hose as shown above and fasten the 90° bend end to the trap and fasten the straight end to the transition drain. Secure both connections with clamps.
Reconnect the 1/2″ (12.7mm) ID drain hose from the vent drain to the trap and secure with a clamp. In some cases, additional length will be required for this hose. Use the Black plastic 1/2″ (12.7mm) OD barbed coupling and a suitable section of 1/2″ (12.7mm) ID hose to make the connection. Secure all connections with clamps
Connect the 3/16″ (4.8mm) ID relief tube from the small port on the trap to the top port of the transition as shown in the picture. In
some cases, additional hose length will be needed. Use the clear plastic 3/16″ (4.8mm) OD flexible tubing connector and a suitable length of extra 3/16″ (4.8mm) ID hose to make this connection.
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. 14.
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.
