FIRE OR EXPLOSION HAZARD - Failure to follow safety warnings exactly could result in serious injury, death, or property damage.
—Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
—WHAT TO DO IF YOU SMELL GAS:
•Do not try to light any appliance.
•Do not touch any electrical switch; do not use any phone (including cell phone) in your building.
•Leave the building immediately.
•Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

SAFETY
This is a safety alert symbol. When you see this symbol on labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation, which, if not avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation, which, if not avoided may result in minor or moderate injury. It is also used to alert against unsafe practices and hazards involving only property damage.
1.The furnace area must be kept clear and free of combustible materials, gasoline and other flammable vapors and liquids.
2.Insulating materials may be combustible. The furnace must be kept free and clear of insulating materials. The furnace area must be examined when installed in an attic or other insulated space or when insulation is added to be sure that the insulation material has been kept away from the furnace.
3.The furnace needs air for combustion in order to operate properly and safely. Do not block or obstruct air openings on the furnace, air openings to the area where the furnace is installed, or spaces around the furnace.
4.Follow the instructions exactly as shown on the OPERATING INSTRUCTION LABEL on the furnace or the “START-UP AND SHUTDOWN INSTRUCTIONS” section of this manual when lighting the furnace or turning the furnace off.
5.Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the furnace before shutting off the electrical supply.
6.Do not use this furnace if any part has been under water. A flooddamaged furnace is extremely dangerous. Attempts to use the furnace can result in fire or explosion. A qualified service agency should be contacted to inspect the furnace and replace all gas controls, control system parts, electrical parts that have been wet or the furnace if deemed necessary.
7.NEVER . . . Store flammable materials of any kind near your furnace. Gasoline, solvents, and other volatile liquids should be stored only in approved containers outside your home. These materials vaporize easily and are extremely dangerous.
8.NEVER . . . Store cleaning materials near your furnace. Materials such as bleaches, detergents, powdered cleansers, etc., can cause corrosion of the heat exchangers.
9.NEVER . . . Use the area around your furnace as a storage area for items which could block the normal flow of air. This flow of air is required for ventilation of the various furnace components.

FIRE OR EXPLOSION HAZARD
This furnace is designed and approved for use with Natural Gas and (LP) Propane Gas ONLY. DO NOT BURN ANY LIQUID FUEL OR SOLID FUEL IN THIS FURNACE.
Burning any unapproved fuel will result in damage to the furnace heat exchanger, which could result in Fire, Personal Injury, and/or Property Damage.
INSTRUCTIONS FOR EXAMINING THE FURNACE INSTALLATION
It is the owner’s responsibility to ensure that an annual inspection of the entire heating portion of the unit is made by a qualified service agency. Examine the furnace as outlined below in steps “1 - 8” before each heating season. Use Figures 1 - 6 for visual reference.

When you set your thermostat to provide more heat in your home, you |
||
|
are starting the heating cycle of the furnace. First, the inducer motor |

|
|
starts to purge the heat exchanger of any remaining gases. Next, the |
||
|
|
hot surface ignitor glows and after a warm-up period the gas valve |
||
|
|
opens and ignition occurs. A short time later, the blower starts and dis- |
||
|
|
tributes the warm air throughout the home. When the temperature set- |
||
|
|
ting on your thermostat is reached, the gas valve closes, the main |
||
|
|
burners are turned off, and the blower continues to run until the remain- |
||
|
|
ing warm air in the system is distributed. When the blower stops, the |

|
|
heating cycle has ended. |
