All Models Vent through Right-Side (SeeFigure13)
Disconnect the black drain tube between the drain vent and the
trap.
Rotate the inducer 180° for a right side vent after loosening the 4
inducer attachment screws. Reinstall and retighten the inducer
screws to 20" pounds torque.
Using the _/2" (12.7mm) OD barbed coupling in the loose parts bag
connect together with the two short 1/2" (12.7mm) ID elbow tubes
and connect the lower discharge port of 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" (12.7mm) PVC pipe long enough
to exit the cabinet and connect the vent drain to either:
• A standard field supplied 2" (12.7mm) PVC tee (N9MP1 or
N9MP2 models), or
• A 2" (12.7mm) PVC coupling fastened onto the drain tee
(N9MPD and *9MPD models)
Install tee trap into bottom section of tee.
Remove knockout from the side of the furnace casing where drain
tube will exit.
Install casing grommet [5/8" (15.9mm) ID grommet -in loose parts
bag].
Install the _/2" (12.7mm) CPVC street elbow on discharge of trap
Install the black PVC tube connector [3/4" (19.1mm) PVC x _/2"
(12.7mm) CPVC from loose parts bag as shown in the illustration
above.
Cut the black drain tube[5/8 " (15.9mm) 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 20.
Note: It is recommended that all PVC piping and fitting
connections be fit up and inspected before final cementing. Both
the internal 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.
