Carrier 58GP - Important Facts for Furnace Operation; Safety Considerations for Heating Equipment; Furnace Starting Procedures

IMPORTANT FACTS
Your furnace must have an adequate supply of air for safe
combustion and ventilation. Do not enclose it in an airtight
room or “seal” it behind solid doors. The furnace may be in
a closet, if air is supplied to the closet in accordance with
the fuel gas codes.
To minimize the possibility of personal injury, fire, furnace
damage, or improper operation—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,
nor block the flow of air to it.
• Combustion air must be clean and uncontaminated by
chlorine or fluorine. 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 that combustion air for your furnace does not
contain any of these compounds. During remodeling be sure
the combustion air is clean and uncontaminated. If these
compounds are burned in your furnace, the heat exchangers
and metal vent system may deteriorate.
• If your furnace is installed in the attic or within any
other insulated space, it must be kept free of the insulating
material. Examine the furnace area when installing—or
when adding more insulation. Some of these materials may
be combustible.
• Do not use this furnace if any part has been under
water. Immediately 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 servicing or 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 Section Before You Request a “Service Call” in this
manual.
SAFETY CONSIDERATIONS
Installation and servicing of heating equipment can be haz¬
ardous due to gas and electrical components. Only trained
and qualified personnel should install, repair, or service
heating equipment.
Untrained personnel can perform basic maintenance func¬
tions 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 furnace and other safety precautions
that may apply.
Recognize safety information: This is the safety-alert sym¬
bol A. When you see this symbol on the furnace and in
instructions or manuals, be alert to the potential for per¬
sonal injury.
Understand the signal word—DANGER, WARNING, or
CAUTION. These words are used with the safety-alert sym¬
bol. DANGER identifies the most serious hazards which
will result in severe personal injury or death. WARNING
on the other hand 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
Your furnace is equipped with one of the following types of
gas control systems:
• The manual ignition system has a continuously burning
pilot flame. This pilot must be match-lit by hand.
The automatic intermittent ignition system does not have a
continuously burning pilot flame. Instead, this pilot is auto¬
matically lit by an electric sparking device each time the
thermostat signals your furnace to start.
Follow these important safeguards:
• Never attempt to manually light the pilot on a furnace
that has an intermittent ignition system by using a match
or any other source of flame.
• Read and follow the lighting or operating instructions
affixed to the furnace blower access door.
• If you suspect a malfunction of your furnace’s gas con¬
trol system, such as the pilot not lighting when it should,
refer to the shutdown procedures found on page 6 of this
manual and the lighting instruction label affixed to the fur¬
nace blower access door. Turn off your furnace. Then, call
your servicing dealer as soon as possible.
■ A WARNING
Should overheating occur, or the gas valve fail to shut
off the gas supply, turn off the external manual gas
valve to the furnace BEFORE turning off the electrical
supply. A failure to adhere to this warning can result in
a fire or explosion and physical injury or death.
CHECK AIR FILTER before starting your furnace. The fil¬
ter should be clean and in place. Refer to page 7 of this man¬
ual for the proper maintenance procedure.
VENT DAMPER: If your furnace is equipped with an
optional automatic vent damper, observe that the damper is
