Safety Considerations; Starting And Shutting Down Your Furnace - Carrier 58MSA User Manual

SAFETY CONSIDERATIONS

Recognize safety information. This is the safety-alert sym-
bol . 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. These words are used with the safe-
ty-alert symbol. DANGER identifies the most serious haz-
ards 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 practic-
es which would result in minor personal injury or product
and prop-erty damage. NOTE: Is used to highlight sugges-
tions which will result in enhanced installation, reliability, or
operation.
To minimize the possibility of serious personal injury, fire,
furnace damage, or improper operation; carefully follow
these safety rules:
Your gas furnace uses air adjacent to the furnace for combus-
tion and vents to the outside. Do not enclose it in an airtight
room or seal it behind solid doors. It must have adequate air-
flow for efficient combustion and safe ventilation. The vent
pipe must terminate outside the structure and must not be
obstructed in any way.
• 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 fluorine. These compounds are present in
many products around the home, such as: water softener
salts, laundry bleaches, detergents, adhesives, paints, var-
nishes, paint strippers, waxes, and plastics.
Make sure the combustion air for your furnace does not con-
tain any of these compounds. During remodeling be sure the
combustion air is fresh and uncontaminated. If these com-
pounds 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 the furnace is installed or when
insulation is added. Some insulation materials may be
combustible.
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.
STARTING AND SHUTTING DOWN
YOUR FURNACE
Should the gas supply fail toshut off or if over heating occurs,
shut off gas valve to the furance before shutting of the elec-
trical supply. Instead of a continuously burning pilot flame
which wastes valuable energy, your furnace uses an automat-
ic, hot surface ignition system to light the burners each time
the thermostat starts your furnace. Follow these important
safeguards:

• Never attempt to light the burners manually with a match
or other source of flame.
• Read and follow the operating instructions on the 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 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 procedures on the inside of main fur-
nace door, or in the "Shutting Down Your Furnace" section

and call your dealer as soon as possible.
