CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation, could result in carbon monoxide poisoning or death:

The following steps shall be followed for each

appliance connected to the venting system being

placed into operation, while all other appliances

connected to the venting system are not in operation:

1.Seal any unused openings in the venting system.

2.Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI

Z223,1/NFPA 54 or CSA B149, 1, Natural Gas and

Propane Installation Code and these instructions. Deter- mine that there is no blockage or restriction, leakage,

corrosion and other deficiencies which could cause an unsafe condition.

3.As far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building.

4.Close fireplace dampers.

5.Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as

range hoods and bathroom exhausts, so they are operating at maximum speed. Do not operate a summer exhaust fan.

6.Followthe lighting instructions. Place the appliance being

inspected into operation. Adjust the thermostat so appliance is operating continuously.

7.Test for spillage from draft hood equipped appliances at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle. (Figure 6)

8.If improper venting is observed, during any of the above

tests, the venting system must be corrected in

accordance with the National Fuel Gas Code, ANSI

Z223,1/NFPA 54 and/or CSA B149. 1, Natural Gas and

Propane Installation Code.

9.After it has been determined that each appliance

connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust

fans, fireplace dampers and any other gas-fired burning appliance to their previous conditions of use.

For Two Pipe Installation

This furnace can NOT be common vented or connected to any type B, BW or L vent or vent connector, nor to any portion of a facto- ry-built or masonry chimney. If this furnace is replacing a previous-

ly common-vented furnace, it may be necessary to resize the existing vent and chimney to prevent oversizing problems for the

other remaining appliance(s). See "Venting and Combustion Air Check"in this section, This furnace MUST be vented to the out- side.

4. Vent and Combustion Air Piping

CARBON MONOXIDE POISONING HAZARD.

Failure to properly vent this furnace could result in death and/or personal injury.

Use methods described here to provide combustion

and ventilation air.

Single Pipe (N9MP1 Models)

combustion and ventilation air must comply with the gas codes or in absence of local codes, the applicable national codes.

When the installation is complete, see the" Venting and Combus- tion Air Che¢l_' in this manual.

Direct Vent (N9MP2 Models)

This furnace is certified as a category ]V appliance. This furnace uses outside air for combustion ONLY, it MUST be taken from the

same atmospheric pressure zone as the vent pipe. See Confined

Space Installation in the Combustion and Ventilation Air in this manual.

Dual Certified (*9MPD Models)

This furnace is certified as a category [V appliance. This furnace requires ventilation openings to provide air for proper combustion and ventilation of flue gases. All duct or openings for supplying

This furnace is certified as a category ]V appliance. This furnace can be installed as a direct vent furnace using outside air for com-

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.
