Bryant 340MAV manual Starting And Shutting Down Your Furnace, Safety Considerations

SAFETY CONSIDERATIONS

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, CAUTION and NOTE. DANGER, WARNING and CAUTION are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe per- sonal injury or death. WARNING signi- fies 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.

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

Your gas furnace uses air from outside the home for combustion and vents flue gas to the outdoors. It is not to be installed using in-house air. The vent and air-intake pipes must ter- minate outside the structure and must not be obstructed in any way. Do not block or obstruct air openings on fur- nace or spaces around the furnace.

5

•Keep the area around your furnace clear and free of combustible materi- als, gasoline, and other flammable liq- uids and vapors.

6

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

•A furnace installed in an attic or other insulated space must be kept free and clear of insulating material. Examine the furnace area when the furnace is installed or when insulation is added. Some insulation materials may be combustible.

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.

!WARNING

Fire Hazard! Failure to keep in- sulation clear of furnace could result in fire, personal injury/ death or property damage.

!WARNING

Do not keep combustible ma- terials, gasoline, and other flammable liquids or vapors around your furnace. Failure to follow this warning could re- sult in fire, personal injury/ death or property damage.

!WARNING

For proper and safe operation the furnace needs air for com- bustion and ventilation. Do not block or obstruct the openings on the furnace, air openings to the area in which the furnace is installed, and the space around the furnace. Failure to follow this warning could re- sult in fire, personal injury/ death or property damage.

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 dete- rioration of the furnace.

6.The pilot and burner flames are in good adjustment (by comparison with pictorial sketches or drawings of the main burner flame and, if applicable, the pilot burner flame).

STARTING AND SHUTTING DOWN 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:

•Never attempt to manually light the burners with a match or other source of flame.

•Read 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
