WELCOME TO TODAY’S GENERATION
OF COMFORT
Congratulations! In light of rising energy costs, a 90+% AFUE
Condensing Gas Furnace from Carrier Corporation is among the
soundest investments today’s homeowner can make.
Your new furnace is truly a triumph of technology in home
heating. A revolutionary design employs two heat exchangers to
“squeeze” out the maximum amount of heat from the fuel
consumed. In fact, your new furnace is so efficient, over 90%* of
the heat generated during combustion is captured and delivered
inside your home.
This furnace is among the safest, most dependable,
energy- efficient furnaces you can buy today. We are proud of the
technological advances incorporated into the design of this furnace.
With only minimal care, your new furnace will deliver many years
of money- saving home comfort and enjoyment. Spend just a few
minutes with this manual to learn the operation of your new
furnace and the small amount of maintenance it takes to help keep
it operating at peak efficiency year after year.
* The output capacity and any representations of efficiency for this furnace
are based on standard U.S. Department of Energy test procedures.

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 heating 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 furnace 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 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 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, damage
to your furnace, or improper operation, carefully follow these
safety rules which apply to both direct-vent and non- direct vent
applications:
S Your new gas furnace may have been installed in one of two
ways, as adirect-vent (2-pipe- Fig. 2) application or as a
non- direct vent (1-pipe- Fig. 3) application.
S 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 application will have two pipes running
from the furnace to theoutdoors. In some cases, the inlet air pipe
may be located in an area that has access to outdoor air, such as
an attic. In all cases, the outlet vent pipe must be routed to the
outdoors. (See Fig. 2.) In this application, the vent and
air-intake pipes must terminate outside the structure and must
not be obstructed in any way. Do not block or obstruct air
openings on furnace or spaces around furnace.
S In a non- direct vent (1- pipe) application, your furnace uses
air from adjacent to the furnace for combustion and vents flue
gas to the outdoors. This type of application will have only one
pipe running from the furnace to the outdoors. (See Fig. 3.) The
other pipe will terminate in the same space as the furnace and is
the source of combustion air for your furnace. Therefore, the
furnace must not be enclosed in an airtight room or be sealed
behind solid doors. It must have adequate airflow for efficient
combustion and safe ventilation. Do not obstruct the
combustion- air pipe in any way. The vent pipe must terminate
outside the structure and must not be obstructed in any way. Do
not block or obstruct air openings or space around furnace.

WARNING
FIRE OR EXPLOSION HAZARD
Failure to follow warnings could result in personal injury,
death, or property damage.
Keep insulation clear of furnace and maintain clearances
shown on unit clearance label.
Do not keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.

WARNING
FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal injury,
death, or property damage.
Do not keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.
S Keep the area around your furnace clear and free of combustible
materials, gasoline, and other flammable liquids and vapors.

Fig. 4 - NO combustible materials near furnace
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 gaps.
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 (by
comparison with pictorial sketches or drawings of the main
burner flame.)

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.
!
CAUTION
UNIT OPERATION HAZARD
Failure to follow this caution may result in intermittent unit
operation.
For proper and safe operation the furnace needs air for
combustion and ventilation. Do not block or obstruct air
openings on the furnace, air opening to the area in which the
furnace isinstalled, and the space around the furnace.
S In addition to the safety rules above, make sure that the
following combustion-air requirements are met for non-direct
vent applications:
S Combustion air must be clean and uncontaminated with chlorine
or fluorine. These compounds are present in many products
around the home, such as: water softener salts, laundry bleaches,
detergents, adhesives, paints, varnishes, paint strippers, waxes,
and plastics.
S 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.
S A furnace installed in an attic or other insulated space must be
kept free and clear of insulating material. Examine the furnace
areawhen the furnace is installed orwhen insulation is added.
Some insulation materials may be combustible.
S 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

FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury, death or property damage.
Should the gas supply fail to shut off or if overheating
occurs, turn off the manual gas valve to the furnace
BEFORE turning off the electrical supply and install
lockout tag.
WARNING
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 signals
the furnace to start.
Follow these important safeguards:
S Never attempt to manually light the burners with a match
or other source of flame.
