Safety Considerations - Bryant 340AAV User's Information Manual

SAFETY
CONSIDERATIONS
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, CAUTION and NOTE.
DANGER, WARNING and CAUTION
are used with the safety-alert symbol.
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
may result in minor personal injury or
product and property damage. NOTE is
used to highlight suggestions which will
result in enhanced installation, reliability,
or operation.
To minimize the possibility of serious
personal injury, fire, damage to
your furnace, or improper operation,
carefully follow these safety rules:
Your new gas furnace may have been
installed in 1 of 2 ways, as a direct-vent
(2-pipe) application or as a non-direct
vent (1-pipe) application.
In a direct-vent (2-pipe) application,
your furnace uses air from outside the
home for combustion and vents flue gas
to the outdoors. This type of applica-
tion will have 2 pipes running from the
furnace to the outdoors. (See Fig. 5.) In
this application, the vent and air-intake
pipes must terminate outside the struc-
ture and must not be obstructed in any
way. Do not block or obstruct air open-
ings on furnace or spaces around
furnace.
In a non-direct vent (1-pipe) applica-
tion, your furnace uses air from adja-
cent to the furnace for combustion and
vents flue gas to the outdoors. This type
of application will have only 1 pipe
running from the furnace to the out-
doors. (See Fig. 6) The other pipe will
terminate in the same space as the fur-
nace and is the source of combustion
air for your furnace. Therefore, the fur-
nace must not be enclosed in an airtight
room or be sealed behind solid doors.
It must have adequate airflow for effi-
cient combustion and safe ventilation.
Do not obstruct the combustion-air
pipe in any way. The vent pipe must ter-
minate outside the structure and must
not be obstructed in any way. Do not
block or obstruct air openings or space
around furnace.
. When you
• Keep the area around your furnace
clear and free of combustible materi-
als, gasoline, and other flammable liq-
uids 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.
In addition to the safety rules above,
make sure that the following combus-
tion-air requirements are met for non-
direct vent applications:
• 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, and plastics.
• Make sure the combustion air for
your furnace does not contain any of
these compounds. During remodeling
be sure the combustion air is fresh and
uncontaminated. If these compounds
are burned in your furnace, the heat
exchangers may deteriorate.
• A furnace installed in an attic or
other insulated space must be kept
5 free and clear of insulating material.
Examine the furnace area when the
furnace is installed or when insulation
is added. Some insulation materials
may be combustible.
• Should the gas supply fail to shut off
or if overheating occurs, shut off the
gas valve to the furnace before shutting
off electrical supply.
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.
FIRE OR EXPLOSION HAZARD
Failure to follow this warning
could result in fire, personal in-
jury/death or property damage.
Do not keep combustible ma-
6
terials, gasoline, and other
flammable liquids or vapors
around your furnace.
