Important Facts; Safety Considerations; Steps For Starting Your Furnace - Bryant CONDENSING GAS FURNACE 340MAV User's Information Manual

IMPORTANT FACTS

Your gas furnace uses air from
outside the home for combustion
and venting. It is not to be installed
using in-house air. Therefore, both
pipes must terminate outside the
structure and must not be obstructed
in any way.
To minimize the possibility of serious
personal injury, fire, damage to
your furnace, or improper operation,
carefully follow these safety rules:
• Keep the area around your furnace
free of combustible materials, gaso-
line, 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.
• A furnace installed in an attic or
other insulated space must be kept
free and clear of insulating material.
Examine the furnace area when install-
ing the furnace or adding more insula-
tion. Some insulation materials may be
combustible.
NOTE:
Do not use this furnace if any
part has been under water. Immedi-
ately 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 modifying this
product.
This furnace contains SAFETY
DEVICES which must be MANU-
ALLY RESET. If the furnace is left un-
attended 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 of heating
equipment can be hazardous due to
gas and electrical components.
Only trained and qualified personnel
should install, repair, or service heat-
ing equipment.
5
Untrained personnel can perform basic
maintenance functions such as cleaning
and replacing air filters. All other oper-
ations must be performed by trained ser-
vice 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 symbol
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, and CAUTION. These
words are used with the safety-alert sym-
bol. DANGER identifies the most serious
hazards which will result in severe per-
sonal injury or death. WARNING signi-
fies 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.
NOTE is used to highlight suggestions
which will result in enhanced installa-
tion, reliability, or operation.
STARTING YOUR
FURNACE
Instead of a continuously burning pilot
flame which wastes valuable energy,

your furnace uses an automatic, hot
surface ignition system to light the
burners each time the thermostat
starts your furnace. Follow these
important safeguards:

manually with a match or other source
of flame.

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 proce-
dures on the furnace, or in the "Shut-
ting Down Your Furnace" section and
call your dealer as soon as possible.

plosion, and personal injury
or death.
