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
would 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 gas furnace uses air from
outside the home for combustion
and vents flue gas to the outdoors. It is
not to be installed using in-house air.
The vent and air-intake pipes must ter-
minate outside the structure and must
not be obstructed in any way. Do not
block or obstruct air openings on fur-
nace or spaces around the furnace.
• Keep the area around your furnace
clear and free of combustible materi-
als, gasoline, and other flammable liq-
uids and vapors.
. When you
• 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 the
furnace is installed or when insulation
is added. Some insulation materials
may be combustible.
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.

BEFORE STARTING
YOUR FURNACE
Examine the furnace installation 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 dete-
rioration of the furnace.
6. The pilot and burner flames are in
good adjustment (by comparison
with pictorial sketches or drawings
of the main burner flame and, if
applicable, the pilot burner flame).
STARTING AND
SHUTTING DOWN
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:
• Never attempt to manually light the
burners with a match or other source of
flame.
• Read and follow the operating
instructions on inside of main furnace
door, especially the item that reads as
follows:
Wait 5 minutes to clear out any gas.
Then smell for gas, including near
