Important Facts; Safety Considerations; Starting Your Furnace - Bryant 393AAV User's Information Manual

IMPORTANT FACTS

Your furnace must have adequate sur-
rounding airflow for efficient combus-
tion 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, damage to your furnace, or im-
proper 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 fluo-
rine. 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 during
remodeling must be fresh and uncon-
taminated. If these compounds are
burned in your furnace, the heat ex-
changers and metal vent system may
deteriorate.
• A furnace installed in the attic or
other insulated space must be kept free
and clear of the insulating material. Ex-
amine 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 in-
spect 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 re-
placement parts, kits, and accessories
when modifying or repairing this product.
This furnace contains safety devices
which must be manually reset or re-
placed. If the furnace is left unattended
for an extended period of time, have it
checked periodically for proper opera-
tion. 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 equip-
ment can be hazardous due to gas and
electrical components. Only trained
and qualified personnel should install,
repair, or service heating equipment.
Untrained personnel can perform basic
maintenance functions such as clean-
3
ing 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 fur-
nace and other safety precautions that
may apply.
Recognize safety information: This is
the safety-alert symbol
see this symbol on the furnace and in
instructions or manuals, be alert to the
potential for personal injury.
Understand the signal words—DAN-
GER, 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 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
Instead of a continuously burning pilot
flame, your furnace uses an automatic
3
hot surface ignition system to light the
burners each time the thermostat sig-
nals the furnace to 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 in-
structions on the furnace, 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! Fol-
low "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 proce-
. When you
!
dures on the furnace, or in the next sec-
tion, 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 fur-
nace BEFORE turning off the
electrical supply. A failure to
follow this warning could re-
sult in a fire or explosion, and
personal injury or death.
• CHECK AIR FILTER: Before at-
tempting to start your furnace, be sure
the furnace filter is clean and in place.
(See the maintenance section of this
manual.) Then proceed as follows:
