Safety Considerations; Before Starting Your Furnace - Carrier 58UVB Owner's Information Manual

SAFETY CONSIDERATIONS

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 personal injury.
Understand the signal words:
CAUTION. 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 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,
furnace damage, or improper operation; carefully follow these
safety rules:
S Your gas furnace uses air from outside the home for
combustion and vents flue gas to the outdoors. It is not
to be installed using indoor air for combustion. The
vent pipe must terminate outside the structure and must
not be obstructed in any way. The air- -intake pipe must
terminate outside the structure or in a well ventilated
area that is isolated from the living space and the garage
(e.g. well ventilated attic or crawlspace). Do not block
or obstruct air openings on furnace or spaces around
furnace.

S Keep the area around your furnace clear and free of
combustible materials, gasoline, and other flammable
liquids and vapors.

S Do not cover the furnace, store trash or debris near it, or
in any way block the flow of fresh air to the unit.
S A furnace installed in an attic or other insulated space
must be kept free and clear of insulating material.
Examine the furnace area when the furnace is installed
or when insulation is added. Some materials may be
combustible.
S 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.

FIRE AND UNIT OPERATION HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
For proper and safe operation the furnace needs air for
combustion and ventilation. Do not block or obstruct
the openings on the furnace, air openings to the area in
which the furnace is installed, and the space around the
furnace.

BEFORE STARTING YOUR FURNACE

Examine the furnace installation monthly to determine that:
1. All flue gas carrying areas external to the furnace (i.e.
chimney, vent connector) are clear and free of
obstructions.
2. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
3. The return- -air duct connection(s) is physically sound, is
sealed to the furnace casing, and terminates outside the
space containing the furnace.
4. The physical support of the furnace is sound without
sagging cracks, gaps, etc. around the base.
5. There are no obvious signs of deterioration of the furnace.
6. The burner flames are in good adjustment. (See Fig. 5.)
