IMPORTANT FACTS

Your gas furnace uses air adjacent to the furnace for combustion and vents to the outside. Do not enclose it in an airtight room or seal it behind solid doors. It must have adequate airflow for efficient combustion and safe ventilation. The vent pipe must terminate outside the structure and must not be obstructed in any way.

To minimize the possibility of serious personal injury, fire, damage to your furnace, or improper operation, carefully follow these safety rules:

Keep the area around your furnace

free of combustible materials, gasoline, and other flammable liquids and vapors.

Do not cover the furnace, store trash or debris near it, or in any way block the flow of fresh air to the unit.

Combustion air must be clean and uncontaminated with chlorine or fluo- rine. These compounds are present in many products around the home, such as: water softener salts, laundry bleaches, detergents, adhesives, paints, varnishes, paint strippers, waxes, and plastics.

Make sure the combustion air for your furnace does not contain any of these compounds. During remodeling be sure the combustion air is fresh and uncontaminated. If these compounds are burned in your furnace, the heat exchangers may deteriorate.

A furnace installed in an attic or other insulated space must be kept free and clear of insulating material. Examine the furnace area when install- ing the furnace or adding more insula- tion. Some insulation materials may be combustible.

NOTE: Do not use this furnace if any part has been under water. Immedi- ately 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.

NOTE: The qualified installer

or agency must use only factory- authorized replacement parts, kits, and accessories when modifying this product.

This furnace contains SAFETY DEVICES which must be MANU- ALLY RESET. If the furnace is left un- attended for an extended period of time, have it checked periodically for proper operation. This precaution will prevent problems associated with no heat, such as frozen water pipes, etc. See “Before You Request a Service Call” section in this manual.

SAFETY

CONSIDERATIONS

Installing and servicing of heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should install, repair, or service heat- ing equipment.

Untrained personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be performed by trained service personnel. Observe safety precautions in this manual, on tags, and on labels attached to the fur- nace and other safety precautions that may apply.

Recognize safety information. This is the safety-alert symbol ! . When you see this symbol on the furnace and in instructions or manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety-alert sym- bol. DANGER identifies the most seri- ous hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage.

STARTING YOUR

FURNACE

Instead of a continuously burning pilot flame which wastes valuable energy, your furnace uses an automatic, hot surface ignition system to light the burners each time the thermostat starts your furnace. Follow these important safeguards:

5

Never attempt to light the burners

manually with a match or other source of flame.

Read and follow the operating instructions on the furnace, especially the item that reads as follows:

Wait 5 minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information above on this furnace label. If you don’t smell gas, go to the next step.

If a suspected malfunction occurs with your gas control system, such as the burners not lighting when they should, refer to the shutdown proce- dures on the furnace, or in the “Shut- ting Down Your Furnace” section and call your dealer as soon as possible.

!WARNING

If overheating occurs or the gas valve fails to shut off the gas supply, turn off the man- ual gas valve to the furnace BEFORE turning off the elec- trical supply. (See Fig. 7.) Fail- ure to follow this warning could result in a fire or explo- sion, and personal injury or death.

CHECK AIR FILTER: Before attempting to start your furnace, be sure the furnace air filter is clean and in place. See “Performing Routine Main- tenance” section in this manual.

Then proceed as follows:
