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.
5
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.
Untrained personnel can perform
basic maintenance functions such as
cleaning 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 . 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 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 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:
7
• Never attempt to light the burners
manually with a match or other source
of flame.
• Read and follow the operating
instructions 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!
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.
CHECK AIR FILTER: Before
attempting to start your furnace, be
sure the furnace air filter is clean and in
place. See “Performing Routine Main-
tenance” section in this manual.
Then proceed as follows:
STEPS FOR STARTING
YOUR FURNACE
1. Set your room thermostat to the
lowest temperature setting.
(See Fig. 8.)
!
WARNING
If overheating occurs or the
gas valve fails to shut off the
gas supply, turn off the exter-
nal manual gas valve to the
furnace BEFORE turning off
the electrical supply. (See Fig.
9.) Failure to follow this warn-
ing could result in a fire or ex-
plosion, and personal injury
or death.
