Upflow Installations Vent thru Left Side (See Figure 10)

Remove Drain Tee from inducer discharge and remove black Drain Tube (1/2" ID) from bottom of Drain Tee. (*9MPD models only)

Install Vent Pipe grommet in side of casing.

Cut an appropriate length of 2" PVC pipe long enough to exit the cabinet and connect the vent drain to either:

•A standard field supplied 2" PVC tee (N9MP1 and 2 models), or

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

Install Tee trap into bottom of tee.

Install the 1/2" CPVC street elbow on discharge of Trap

Install the black PVC drain connector (3/4" PVC x 1/2" CPVC from loose parts bag) as shown in the illustration above.

Cut the black Drain Tube (5/8" ID - in loose parts bag) to length to fit between Trap and tube connector through grommet.

Clamp both ends of the Drain Tube using clamps provided.

Glue the CPVC street elbow to the Trap using appropriate cleaner and solvent cement.

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 in-

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.
