IMPORTANT FACTS (DO’S AND DON’TS)

SDO: READ AND UNDERSTAND THIS MANUAL.

SDO: Have your furnace and vent system inspected annually by a qualified service technician.

SDO: Inspect your filter monthly and clean or replace when needed.

SDO: Provide adequate airflow to the furnace for efficient combustion and safe ventilation.

SDO: Keep your furnace free and clear of insulating material. Some materials may be combustible. Examine the furnace area when the furnace is installed or when insulation is added.

SDO NOT: Enclose your furnace in an airtight room or seal it behind solid doors.

SDO NOT: Keep combustible materials, gasoline, and other flammable liquids or vapors around your furnace.

SDO NOT: Cover your furnace in any manner.

SDO NOT: Store anything (including trash or debris) near your furnace.

SDO NOT: In any way block or restrict airflow around your furnace.

SDO NOT: In any way block or restrict airflow to your supply air and return air grills.

SDO NOT: Use your furnace room as a broom closet or a place to store any kind of chemical or cleaner.

SDO NOT: Contaminate the air used for combustion of your furnace with any kind of chemical or fumes. This could also cause heat exchangers, metal vent systems or components to deteriorate.

NOTE: These chemicals or fumes are present in many products around the home, such as: water softener salts, any type of household cleaning product, any type of laundry product, adhesives, paints, varnishes, paint strippers, waxes and plastics, etc.

During remodeling be sure the combustion air is fresh and uncontaminated. If these compounds are burned in your furnace, the heat exchangers and metal vent system may deteriorate.

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 manually reset. If the furnace is left unattended 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.

!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in injury, death, or property damage.

Do not keep combustible materials, gasoline, and other flammable liquids or vapors around your furnace.

!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow warnings could result in personal injury, death, or property damage.

Keep insulation clear of furnace and maintain clearances shown on unit clearance label.

SAFETY CONSIDERATIONS

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

Untrained personnel can perform basic maintenance functions such as cleaning or 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 furnace, 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 symbol. DANGER identifies the most serious 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. NOTE is used to highlight suggestions which will result in enhanced installation, reliability or operation.

BEFORE STARTING YOUR FURNACE

Examine the furnace installation to determine that:

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

2.The vent connector is in place, slopes upward and is physically sound without holes or excessive corrosion.

3.The return−air duct connection(s) is physically sound, is sealed to the furnace casing, and terminates outside the space containing the furnace.

4.The physical support of the furnace is sound without sagging cracks, gaps, etc. around the base.

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

STARTING YOUR FURNACE

Your furnace uses an automatic, hot surface ignition system to light the burners each time the thermostat signals the furnace to start.

Follow these important safeguards:

SNever attempt to manually light the burners with a match or other source of flame.

Figure 3 − Do Not Light Burner with Match

A92319

SRead and follow the operating instructions on inside of main furnace door, 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
