I Mportant Facts; Safety Considerations; Starting Your Furnace - Carrier INDUCED COMBUSTION 58YAV User's Information Manual

I mportant facts

Your furnace must have adequate surrounding airflow for
efficient combustion and safe ventilation. Do not enclose
it in an airtight room or "seal" it behind solid doors.
To minimize the possibility of serious personal injury, fire,
furnace damage, or improper operation; carefully 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, 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, varnishes,
paint strippers, waxes, and plastics.
Make sure the combustion air for your furnace does not
contain any of these compounds. The combustion air dur-
ing remodeling must be fresh and uncontaminated. If these
compounds are burned in your furnace, the heat exchang-
ers 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 furnace area when installing the furnace or adding
more insulation. Some materials may be combustible.
NOTE: 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 accesso-
ries when modifying this product.
This furnace contains safety devices which must be man-
ually reset or replaced. If the furnace is left unattended for
an extended period of time, have it checked periodically
for proper operation. This precaution will prevent prob-
lems 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 hazard-
ous due to gas and electrical components. Only trained and
qualified personnel should install, repair, or service heat-
ing 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 person-
nel. Observe safety precautions in this manual, on tags,
and on labels attached to the furnace and other safety pre-
cautions that may apply.
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 per-
sonal injury.
Understand the signal words — DANGER, WARNING,
and CAUTION. 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 which could result in per-
sonal 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

Instead of a continuously burning pilot flame, your furnace
uses an automatic hot surface ignition system to light the
burners each time the thermostat signals the furnace to
3
start. 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 the fur-
nace, 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 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 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.
Should overheating occur, or the gas valve fail
to shut off the gas supply, turn off the manual
gas valve (See Fig. 6) to the furnace BEFORE
turning off the electrical supply. A failure to
follow this warning could result in a fire or ex-
plosion, 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:
