Downflow Left Side Vent and Trap (SeeFigure 12)

Remove the inducer mounting screws, rotate the inducer 180 ° and retighten the inducer screws to 20" pounds torque.

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 left side of the unit using the 2 screws provided.

Cut the 5/8" ID corrugated hose as shown above and fasten the 90 ° bend end to the Trap and fasten the straight end to the transition drain. Secure both connections with clamps.

Reconnect the 1/2" ID drain hose from the vent drain to the Trap and secure with a clamp.. In some cases, additional length will be required for this hose. Use the Black plastic 1/2" OD barbed cou- pling and a suitable section of 1/2" ID hose to make the connection.

Secure all connections with clamps

Connect the 3/16" ID relief tube from the small port on the Trap to

the top port of the transition as shown in the picture. In some

cases, additional hose length will be needed. Use the clear plastic 3/16" OD flexible tubing connector and a suitable length of extra 3/16" ID hose to make this connection.

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.

9MPD100J20B1, N9MP2100J20B1, 9MPD050F12B1, N9MP1100J20B1, N9MP1125J20B1 specifications

The Sears N9MP1075B12B1, N9MPD125L20B1, N9MP1050B12B1, N9MPD080J16B1, and N9MP2125J20B1 are part of the trusted line of gas furnaces manufactured by Sears, specifically designed to deliver reliable heating solutions for residential applications. These models incorporate cutting-edge technology and robust engineering, making them popular choices among homeowners looking for efficiency and comfort.

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.
