NOTE - This manual must be left with the equipment user.

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 appliance before shutting off electrical supply.

CAUTION

Before attempting to perform any service or mainteĆ nance, turn the electrical power to unit OFF at the disconnect switch.

WARNING

Do not use this furnace if any part has been under water. Immediately call a qualified service technician to inspect the furnace and to replace any part of the control system and any gas control which has been under water.

IMPORTANT

Any additions, changes, or conversions required in order for the appliance to satisfactorily meet the apĆ plication needs must be made by a Lennox service technician using factory specified and approved parts.

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause property damage, personĆ al injury or loss of life. Installation and service must be performed by a qualified installer, service agency or the gas supplier.

Important Directions

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 maĆ terial may be combustible.

2 - DO NOT obstruct air flow to unit. Unit must receive an unobstructed flow of combustion and ventilating air.

3 - DO NOT store chlorine or fluorine products near unit or introduce these products into the combustion air.

These products can cause furnace corrosion.

4 - DO NOT draw return air from a room where this furĆ nace, or any other gas appliance (ie., a water heatĆ er), is installed. When return air is drawn from a room, a negative pressure is created in the room. If a gas apĆ 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 proĆ 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 injuĆ ry and even death to all occupants, including pets. Any item that is powered by, or gives off heat from, a combustion proĆ 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 monoxĆ 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 nationĆ al agencies. It should operate safely when properly installed and maintained. However, the unit's perforĆ mance can be greatly impacted by the individual installaĆ tion and the operating environment. It is your responsibilĆ ity to ensure that this appliance is maintained. Proper maintenance is critical for your safety and the satisfactory operation of the product. Lennox strongly recommends annual inspection and maintenance of this appliance.

Contact your Lennox dealer for an inspection by a qualiĆ fied service technician.

Lighting Information & Operation

WARNING

If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or death.

BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

Filters

This unit is not equipped with a filter or rack. A field-proĆ vided, high-velocity filter is required to ensure proper unit operation.

A filter must be in place any time the unit is operating.

Seasonal Inspections

A qualified service technician should inspect the complete system each season (heating and cooling). The following maintenance procedures should only be conducted by a qualified service technician. Do not attempt to service the unit in any way.

Venting System

WARNING

Asphyxiation Hazard

The exhaust vent for this furnace must be securely connected to the furnace flue collar at all times.

For your safety and to fulfill the terms of the limited warranty, a qualified service technician must annualĆ ly inspect this furnace and its vent system.

Annually (before heating season) inspect furnace venting system, vent cap, heat exchanger and burners for corroĆ sion, deterioration, or deposits of debris. Remove any obĆ structions.

Inspect thefurnace venting system to make sure it is in place, physically sound and without holes, corrosion, or blockage. The vent connector must be correctly posiĆ tioned and sloped upward. The vent connector must be physically sound, without holes or excessive corrosion.

Inspect the furnace return air duct connection. The duct must be sealed to the furnace and it must terminate outside the space containing the furnace.

Inspect the physical support of the furnace to guarantee that it is sound. The support must not sag and must not have cracks or gaps around the base of the furnace. There must be a seal between the furnace base and the support.

During a seasonal check, the service technician will inĆ spect the indoor blower and the burner flames along with the venting system.

Blower

Check blower wheel for any debris and clean it, if necesĆ sary. The blower motor is pre-lubricated for extended bearĆ ing life. No further lubrication is needed.

Burner Flame

CAUTION

To ensure proper operation, a qualified technician should annually check the burner flame.

Service Reminder

Call your Lennox service technician if the unit will not operĆ ate. Before calling, always check the following to be sure service is required.

1 - Check that electrical disconnect switches are ON.

2 - Check room thermostat for proper setting.

3 - Replace any blown fuses or reset circuit breakers.

4 - Gas valve should be ON.

5 - Air filter should not be plugged, which wil limit air flow.

Safety Precautions

If you discover any of the following, shut down your unit and contact a Lennox dealer for an inspection by a qualified technician.

D

D

If you repeatedly hear any new or unfamiliar sounds while your unit is operating, there may be a problem. For example, poorly performing burners can produce unfaĆ miliar noises.

If you smell any unusual odors, your unit may be operatĆ ing improperly. For example, units can give off unfamilĆ iar odors if components are required to operate in abĆ normal conditions.

D

D

Look for visible signs of a malfunctioning unit. Examples include unusual amounts of condensate on windows inĆ side your house, visibly burnt components or unusual dirt or rust accumulations on the vent pipe or in the unit.

If you experience headache, nausea, fatigue, or dizziĆ ness, the cause could be exposure to carbon monoxide gas. This is often misdiagnosed as the flu because symptoms are similar. If you suffer from flu-like sympĆ toms that are exaggerated at home, but seem to subĆ side while you are away from the house, exposure to carbon monoxide could be the cause.

Your vigilance may pay off in early detection of a problem before either personal injury or property damage occurs.

Do not hesitate to contact a qualified service technician as an investment in your well being.
