Carrier 58ZAV - Manual (Page 4)

IMPORTANT FACTS
Your furnace must have adequate airflow for efficient combus­
tion and safe ventilation. Do not enclose it in an airtight room
or “seal” it behind solid doors.
lb minimize the possibility of serious personal injury, fire, fur­
nace damage, or improper operation; carefully follow these
safety rules:
• Keep the area around your furnace free of combustible mate­
rials, 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, laun­
dry
bleaches, detergents, adhesives, paints, varnishes, paint
strippers, waxes, and plastics.
Make sure the combustion air for your furnace does not contain
any of these compounds. During remodeling be sure the com­
bustion air is fresh and uncontaminated. If these compounds
are burned in your furnace, the heat exchangers and metal vent
system may deteriorate.

• A furnace installed in an attic or other insulated space must
be kept free and clear of insulating material. Examine the fur­
nace area when installing the furnace or adding more insula­
tion. Some materials may be combustible.
NOTE: Do not use this furnace if any part has been under wa­
ter. 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 modi­
fying 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.
SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazardous
due to gas and electrical components. Only trained and quali­
fied
personnel should install, repair, or service heating
equipment.
Untrained personnel can perform basic maintenance functions
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 labels attached to the
furnace and other safety precautions that may apply.
Recognize safety information: This is the safety-alert symbol
A. When you see this symbol on the furnace and in instruc­
tions or manuals, be alert to the potential for personal injury.
Understand the signal word—DANGER, WARNING, or CAU­
TION. 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
that could result in personal injury or death. CAUTION is used
to identify unsafe practices, which would result in minor per­
sonal injury or product and property damage.
STARTING YOUR FURNACE
Instead of a continuously burning pilot flame, your furnace
uses an automatic hot surface ignition system to light the burn­
ers each time the thermostat turns your furnace on. Follow
these important safeguards:
• Never attempt to manually light the burners with a match or
other source of flame.
A86024
• Read and follow the operating instructions on the furnace,
especially the item that reads as follows:
Wait 5 minutes to clear out any gas. Then smell for gas, includ­
ing near the floor. If you smell gas, STOP! Follow “B” in the
safety information above on this label. If you don’t smell gas, go
to the next step.
• If a suspected malfunction occurs with your gas control sys­
tem, such as the burners do not light when they should, refer to
the shutdown procedures on the furnace or in the next section
to turn off your system, then call your dealer as soon as
possible.
A WARNING
Should overheating occur, or the gas valve fail to shut off
the gas supply, turn off the manual gas valve (see Fig. 8) to
the furnace BEFORE turning off the electrical supply. A
failure to follow this warning could result in a fire or explo­
sion, and personal injury or death.
• CHECK AIR FILTER: Before attempting to start your fur­
nace, be sure the furnace filter is clean and in place. (See the
maintenance section of this manual.) Then proceed as follows:
STEPS FOR STARTING YOUR FURNACE
1. Set your room thermostat to the lowest temperature set­
ting. (See Fig. 7.)
2. Close the external manual gas valve. (See Fig. 8.)
3. Tbrn OFF the electrical supply to the furnace. (See Fig. 9.)
