Disconnect Drain Tee if installed ('9MPD models only)

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.

Mount the Trap externally to the bottom side of the unit using the 2 screws provided in the location shown.

Cut the corrugated tube as shown in the illustration above. Con- nect the corrugated hose from the transition to the Trap. Secure

connections with clamps.

Connect the black 1/2" ID Drain Tube from the Vent Drain to the Trap. If an extension is required, use the 1/2" OU barbed coupling and the black 1/2" ID Drain Tube in the loose parts bag. Cut tube

to length. Secure connections with clamps.

Connect the 3/16" ID relief tube to the middle port on the Trap. If an extension is required, use the clear 3/16"OD splice connector and the black 3/16" ID relief tube in the loose parts bag. Cut tube to length.

Cut an appropriate length of 2" PVC pipe, fittings and extension

pipe long enough to exit the cabinet and connect the vent drain to either:

•A standard field supplied 2" PVC tee (N9MP1 and 2 mod- els), or

•A 2" PVC coupling fastened onto the Drain Tee (*9MPD models)

Install Tee Trap into bottom section of Tee.

Important: The pipe to the Tee Trap must be level or sloping to- wards the Tee Trap

Connect the Tee trap and the main drain line exiting the casing as shown in Figure 18.

Note: It is recommended that all PVC piping and fitting connec- tions be fit up and inspected before final cementing. Both the ex-

ternal 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.
