Upflow Installations Top Vent (See Figure 9)

Remove plug from the side of the furnace casing where Drain Tu be will exit.

Install casing grommet (black rubber 5/8" ID grommet - in loose parts bag)

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

Install the black PVC tube 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 Figure 18.

Note: It is recommended that all PVC piping and fitting connec- tions be fit up and inspected before final cementing. Trap must be

primed before operation. Verify all condensate drain connec- tions are securely clamped. A coupling and clamps (in loose part bag) may be installed as shown for future servicing of the vent sys- tem.

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.
