Downflow Right Side Vent and Trap (SeeFigure 13)
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 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" 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 ex-
tension is required, use the black 1/2" OD barbed coupling, con-
nect a black 1/2" ID elbow tube and a suitable section of a 1/2" ID
drain tube to make connection from the vent drain to the trap. Se-
cure all connections with clamps.
Install the vent pipe grommet into the 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 mod-
els), or
• A 2" PVC coupling fastened onto the Drain Tee ('9MPD
models)
Install Tee Trap into bottom section of Tee.
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.
