WARNING

Do not set thermostat below 60°F (16°C) in heating mode. Setting thermostat below 60°F (16°C) reduces the number of heating cycles. Damage to the unit may occur that is not covered by the warranty.

WARNING

If overheating occurs or if gas supply fails to shut off, shut off the manual gas valve to the furnace before shutting off electrical supply.

WARNING

Do not use this furnace if any part has been under- water. A flood−damaged furnace is extremely dan- gerous. Attempts to use the furnace can result in fire or explosion. Immediately call a licensed pro- fessional service technician (or equivalent) to in- spect the furnace and to replace all gas controls, control system parts, and electrical parts that have been wet or to replace the furnace, if deemed neces- sary.

NOTICE

Any additions, changes, or conversions required in order for the appliance to satisfactorily meet the ap- plication needs must be made by a licensed profes- sional installer (or equivalent) using factory−speci- fied and approved parts.

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause property damage, person- al injury or loss of life. Installation and service must be performed by a licensed professional installer (or equivalent), a service agency, or the gas supplier.

Safety Instructions

1 − Keep the furnace area clear and free of combustible

material, gasoline, and other flammable vapors and

liquids. If it is installed in an insulated area, the furnace

must be kept free of insulating material. Insulating ma-

terial may be combustible.

2 − After any heavy snow, ice or frozen fog event, the fur-

nace vent pipes may become restricted. Always check

the vent system and remove any snow or ice that may

be obstructing the plastic intake or exhaust pipes.

3 − DO NOT obstruct air flow to unit. Unit must receive an unobstructed flow of combustion and ventilating air. DO NOT block or obstruct air openings on the furnace or air openings to the area in which the furnace is installed. Take care to maintain established clear- ances surrounding the furnace.

4 − DO NOT store chlorine or fluorine products near unit or introduce these products into the combustion air. These products can cause furnace corrosion.

5 − DO NOT draw return air from a room where this fur- nace, or any other gas appliance (ie., a water heat- er), is installed. When return air is drawn from a room, a negative pressure is created in the room. If a gas ap- pliance is operating in a room with negative pressure, the flue products can be pulled back down the vent pipe and into the room. This reverse flow of the flue gas may result in incomplete combustion and the formation of carbon monoxide gas. This toxic gas might then be distributed throughout the house by the furnace duct system.

WARNING

The blower door must be securely in place when the blower and burners are operating. Gas fumes, which could contain carbon monoxide, can be drawn into the living space resulting in personal injury or death.

Your furnace is a gas appliance. It is critical that the gas supplied to the unit be completely burned to avoid the pro- duction of carbon monoxide gas. Complete combustion of the gas requires, but is not limited to, correct gas pressure and gas flow rate, adequate combustion, air, and proper venting.

WARNING

Carbon monoxide gas is invisible, odorless and toxic.

Exposure to carbon monoxide gas can cause personal inju- ry and even death to all occupants, including pets. Any item that is powered by or gives off heat from a combustion pro- cess (including lawn mowers, automobiles, and fireplaces) has the potential to produce carbon monoxide gas. Because of this, Lennox recommends the use of a carbon monox- ide detector in your home, even if you do not own gas appliances. Reliable detectors are available at reasonable retail prices. Contact your Lennox dealer for more details about this investment in your safety.

Your furnace is designed to meet standards set by nation- al agencies, and to operate safely when properly installed and maintained. However, the unit’s performance can be

EL195UH SERIES, Gas Furnace specifications

The Lenox EL195UH Series gas furnace is an efficient and reliable heating solution designed to provide exceptional comfort in residential settings. With a focus on performance, efficiency, and advanced technology, this furnace has become a popular choice among homeowners looking for a dependable heating system.

One of the standout features of the EL195UH Series is its high efficiency rating. With an Annual Fuel Utilization Efficiency (AFUE) rating of up to 95%, this gas furnace converts a significant portion of fuel into heating energy, minimizing waste and reducing energy costs. This efficiency not only benefits homeowners financially but also contributes positively to the environment by lowering greenhouse gas emissions.

The furnace incorporates a two-stage gas valve, which allows for greater temperature control and comfort. This technology enables the furnace to operate at a lower heating capacity during milder conditions, ensuring consistent temperatures while saving energy. When the temperatures drop, the furnace can ramp up to its higher capacity, providing the necessary warmth quickly and efficiently.

Another key characteristic of the Lenox EL195UH is its quiet operation. Equipped with a variable-speed blower motor, this furnace operates more quietly than traditional models. The motor adjusts its speed according to the heating demands, which not only enhances comfort through more even air distribution but also reduces noise levels in the home.

The EL195UH Series is designed for durability and longevity. It features a robust heat exchanger, constructed from high-quality materials that withstand the rigors of constant heating and cooling. Additionally, the furnace comes with a limited lifetime warranty on the heat exchanger, providing peace of mind to homeowners regarding their investment.

To enhance convenience, the EL195UH Series is compatible with smart home technology. Homeowners can integrate their furnace with smart thermostats, allowing for remote control and programming, which optimizes heating schedules based on lifestyle preferences.

In summary, the Lenox EL195UH Series gas furnace combines high efficiency, advanced technology, and quiet operation to create a top-tier heating solution. With its two-stage gas valve, durable construction, and compatibility with smart technology, this furnace is designed to meet the needs of modern homeowners while providing comfort and reliability throughout the heating season. Whether for new installations or as a replacement for an older system, the EL195UH Series stands out as a premier choice in home heating solutions.
