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.

Remove the black I/2" ID Drain Tube from the Drain Tee. Install a yellow cap and clamp over the open drain port of the Drain Tee.

Connect the black I/2" ID Drain Tube from the Vent Drain to the

Trap. 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 3116" OD flexible tubing connector

and the black 3/16" ID relief tube in the loose parts bag. Cut tube

to length. Secure all connections with clamps.

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.

One of the main features of these models is their high-efficiency operation. With Annual Fuel Utilization Efficiency (AFUE) ratings exceeding 90%, these furnaces convert a significant portion of fuel into usable heat, thereby reducing energy costs. The N9MP series employs a multi-speed blower system that optimizes airflow for enhanced comfort while minimizing noise levels, ensuring a pleasant indoor environment.

The N9MPD125L20B1 and N9MPD080J16B1 variants highlight their adaptability through dual-stage heating capabilities. This technology allows the furnace to adjust its output based on the thermal demands of the home, preventing energy wastage during milder conditions while providing robust heating during extreme cold spells. The two-stage combustion process not only improves comfort but also contributes to lower greenhouse gas emissions.

Durability is another hallmark of these Sears models. With heavy-duty heat exchangers crafted from high-quality materials, they are built to withstand the rigors of regular use. Additionally, the inclusion of advanced safety mechanisms ensures that the system operates securely, reducing potential risks associated with gas furnaces.

The N9MP2125J20B1 model stands out due to its whisper-quiet operation. Homeowners can enjoy a warm home without the disruptive sound commonly associated with traditional heating systems, thanks to the insulated cabinet design and efficient blower operation.

Furthermore, these models come equipped with user-friendly digital thermostats, which allow precise temperature control and programmable settings, enabling homeowners to tailor their heating needs to fit their lifestyle. The compatibility with smart home systems also adds convenience, enabling users to manage their heating remotely, saving even more energy.

In conclusion, the Sears N9MP1075B12B1, N9MPD125L20B1, N9MP1050B12B1, N9MPD080J16B1, and N9MP2125J20B1 gas furnaces exemplify innovation in heating technology. Their energy-efficient designs, advanced features, and durable construction make them reliable choices for homeowners seeking comfort and sustainability in their heating solutions.
