Important: Environmental Concerns! Scientific research has shown that certain man-made chemicals can af fect the earth's naturally occur ring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Important: Responsible Refrigerant Practices! Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

Personal Protective Equipment Required!

Installing/servicing this unit could result in exposure to electrical, mechanical and chemical hazards. Before installing/servicing this unit, technicians MUST put on all Personal Protective Equipment (PPE) recommended for the work being undertaken. ALWAYS refer to appropriate MSDS sheets and OSHA guidelines for proper PPE.

Important Safety Instructions

Safety Instructions!

Failure to follow instructions in this section could result in death, serious injury, and property damage.

General Safety Instructions

• Do not store combustible materials, gasoline or other flammable vapors and liquids near the unit.

• Should overheating occur, or the gas supply fail to shut off , shut off the manual gas valve to the furnace before shutting off the electrical supply.

• 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 system and any gas control which has been under water.

• Never perform any maintenance procedures until the electrical power and/or gas supply to the unit has been turned off.

• Never remove any panels from the unit while it is operating.

• Never remove panels or parts from this unit that are not discussed in this manual.

• Never cover the unit, since it is designed to operate year-round.

• The furnace area must be kept clear and free of combustible materials, gasoline and other flammable vapors and liquids.

• For proper and safe operation the furnace needs air for combustion and ventilation. Do not block or obstruct air openings on the furnace, air openings communicating with the areas in which the furnace is installed, and the spacing around the furnace.

At installation and the beginning of each heating season, a qualified service technician should examine the furnace to ensure:

• All flue products carrying areas external to the furnace, (i.e., chimney, vent connector, etc.), are clear and free of obstructions.

• The physical support of the furnace is sound and without sagging, cracks, gaps, etc., around the base so as to provide a seal between the support and the base.

• There are no obvious signs of deterioration of the furnace.

Safety Instructions Before Operating the Unit

• This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand.

• BEFORE OPERATING 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.

What To Do If You Smell Gas

• Do not try to light any appliance.

• Do not touch any electric switch ; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

• If you cannot reach your gas supplier, call the fire department.

Temperature Control Devices

Room thermostats and zone sensors are delicate temperature control devices.

Thermostats’ main function is to energize and de-energize the heating or cooling circuit to maintain the temperature setting you select.

Zone sensors’ main function is to sense the room temperature to allow the unit controls to activate the heating and cooling functions to maintain the temperature setting you select.

Many thermostats and zone sensors contain a room thermometer to indicate the approximate room temperature, and a temperature scale at the adjustment indicator to select the desired indoor air temperature. In addition, most controls have a selector mode switch with Heat, Off and Cool positions, and a fan switch with On and Auto positions.

When the selector switch is positioned at Off, your unit will not operate in either the heat or cool modes. If the selector switch is set at Heat, the unit will automatically cycle on and off to maintain the desired temperature setting. The unit will also operate automatically when the selector switch is positioned at Cool.

The fan selector switc h can be used to op erate the ind oor fan contin uously by positioning it at On. When set at Auto, the fan will only operate when required during the heating or cooling cycles.

T o ensure that the thermostat or zone sensor operates properly , it must be level and positioned to avoid the influence of such external heat sources such as lamps, televisions or other heat producing appliances.

Air Filters

It is very important to keep the central duct system air filters clean. Be sure to inspect them at least once each month when the system is in constant operation. (In new homes, chec k the filters every week for the first 4 weeks.) See Table 1 for the required filter size(s).

If you have disposable type filters, replace them with new filters of the same type and size. Do not attempt to clean disposable filters.

Permanent type filters can be cleaned by washing them with a mild detergent and water. Ensure that the filters are thoroughly dry before reinstalling them in the unit (or duct system).

Note: It may be necessary to replace permanent filters annually if washing fails to clean the filter, or if the filter shows signs of deterioration. Be sure to use the same type and size as was originally installed.

Heating System

Heating Cycle Operation

A normal heating cycle begins when the air temperature in your home drops below the selected setting. The control then energizes the heating electrical circuit that starts and controls the main burners. Shortly after the main burners ignite, the indoor fan starts and circulates warm air through your home, or building.

When the air temperature rises to the selected setting, the control deenergizes the heating electrical circuit which, in turn, extinguishes the main burners. The indoor fan continues to circulate warm air until most of the heat is removed from the unit’s combustion chamber.

Safety Controls

Y our unit is equipped with automatic reset safety limit controls to prevent overheating. When one of these controls open, it shuts down the heating electrical circuit until it cools down sufficiently. Inadequate airflow (i.e., caused by dirty air filters or a defective fan motor) may cause the unit to cycle on and off as the limit controls trip and automatically reset. If you suspect that the unit is cycling on its limit controls, immediately contact a serviceman for instructions.

Operating Instructions

1. Set the temperature control to lowest setting.

2. Turn off all electric power to the appliance.

3. This appliance is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand.
