CAREFULLY FOLLOW THESE
SAFETY RULES:
1. Combustible material must not be
placed on or against the furnace
jacket. The area around the
urnace must be kept clear and
f
free of all combustible materials
including gasoline and other
flammable vapors and liquids.
2. A furnace installed in an attic or
other insulated space must be kept
free and clear of insulating
material. Examine the furnace area
when installing the furnace or
adding more insulation. Some
materials may be combustible.
3. To prevent carbon monoxide
poisoning, all blower doors and
compartment covers must be
replaced after the furnace is
serviced. Do not operate the unit
without all panels and doors
securely in place.
4. Should overheating occur, or the
gas valve fail to shut off the gas
supply, turn off the manual gas
valve to the furnace before turning
off the electrical supply.
5. Any additions, changes or
conversions required in order for
the furnace to satisfactorily meet
the application needs should be
made by a qualified installer,
service agency or the gas supplier,
using factory specified or approved
parts. Read your WARRANTY.
Contact the WARRANTOR for
conversion information. This
furnace was equipped at the
factory for use on NATURAL GAS
ONLY. Conversion to L.P. GAS
requires a special kit supplied by
the WARRANTOR.
6. A furnace needs an adequate
supply of combustion and
ventilation air for proper and safe
operation. Do not block or obstruct
air openings on the furnace or air
openings supplying the area where
the furnace is installed. Do not
store anything around the furnace
that could block the flow of fresh air
to the unit. Your installation may
DO NOT DESTROY. PLEASE READ CAREFULLY AND KEEP IN A SAFE PLACE FOR FUTURE REFERENCE.

WARNING
DUCT LEAKS CAN CREATE AN
UNBALANCED SYSTEM AND DRAW
POLLUTANTS SUCH AS DIRT, DUST,
FUMES AND ODORS INTO THE
HOME CAUSING PROPERTY
DAMAGE. FUMES AND ODORS
FROM TOXIC, VOLATILE OR
FLAMMABLE CHEMICALS, AS WELL
AS AUTOMOBILE EXHAUST AND
CARBON MONOXIDE (CO), CAN BE
DRAWN INTO THE LIVING SPACE
THROUGH LEAKING DUCTS AND
UNBALANCED DUCT SYSTEMS
CAUSING PERSONAL INJURY OR
DEATH (SEE FIGURE 1).
• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
GARAGES OR OFF-GARAGE
STORAGE AREAS - ALL JOINTS,
SEAMS, AND OPENINGS IN THE
EQUIPMENT AND DUCT MUST BE
SEALED TO LIMIT THE
MIGRATION OF TOXIC FUMES
AND ODORS INCLUDING CARBON
MONOXIDE FROM MIGRATING
INTO THE LIVING SPACE.
• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
SPACES CONTAINING FUEL
BURNING APPLIANCES SUCH AS
WATER HEATERS OR BOILERS ALL JOINTS, SEAMS, AND
OPENINGS IN THE EQUIPMENT
AND DUCT MUST ALSO BE
SEALED TO PREVENT
DEPRESSURIZATION OF THE
SPACE AND POSSIBLE
MIGRATION OF COMBUSTION
BYPRODUCTS INCLUDING
CARBON MONOXIDE INTO THE
LIVING SPACE.

IMPORTANT INFORMATION
ABOUT EFFICIENCY AND
INDOOR AIR QUALITY
Central cooling and heating equipment
is only as efficient as the duct system
that carries the cooled or heated air. To
maintain efficiency, comfort and good
indoor air quality, it is important to have
the proper balance between the air
being supplied to each room and the air
returning to the cooling and heating
equipment.
Proper balance and sealing of the duct
system improves the efficiency of the
heating and air conditioning system and
improves the indoor air quality of the
home by reducing the amount of
airborne pollutants that enter homes
from spaces where the ductwork and / or
equipment is located. The manufacturer
and the U.S. Environmental Protection
Agency’s Energy Star Program
recommend that central duct systems be
checked by a qualified contractor for
proper balance and sealing.

RECEIVING
Immediately upon receipt, all cartons
and contents should be inspected for
transit damage. Units with damaged
cartons should be opened immediately.
If damage is found, it should be noted
on the delivery papers, and a damage
claim filed with the last carrier.
• After unit has been delivered to job
site, remove carton taking care not to
damage unit.
• Check the unit rating plate for unit
size, electric heat, coil, voltage,
phase, etc. to be sure equipment
matches what is required for the job
specification.
• Read the entire instructions before
starting the installation.
• Some building codes require extra
cabinet insulation and gasketing
when unit is installed in attic
applications.
• If installed in an unconditioned space,
apply caulking around the power
wires, control wires, refrigerant tubing
and condensate line where they enter
the cabinet. Seal the power wires on
the inside where they exit conduit
opening. Caulking is required to
prevent air leakage into and
condensate from forming inside the
unit, control box, and on electrical
controls.
• Install the unit in such a way as to
allow necessary access to the
coil/filter rack and blower/control
compartment.
2
• Install the unit in a level position to
ensure proper condensate drainage.
Make sure unit is level in both
directions within 1/8”.
• Install the unit in accordance with any
local code which may apply and the
national codes. Latest editions are
available from: “National Fire
Protection Association, Inc.,
Batterymarch Park, Quincy, MA
02269.” These publications are:
• ANSI/NFPA No. 70-(Latest Edition)
National Electrical Code.
• NFPA90A Installation of Air
Conditioning and Ventilating
Systems.
SYSTEM OPERATION INFORMATION
1. Keep the air filters clean. Your
eating system will operate more
h
efficiently and provide better
heating, more economically.
2. Arrange your furniture and drapes
so that the supply air registers and
the return air grilles are
unobstructed.
3. Close doors and windows. This will
reduce the heating load on your
system.
4. Avoid excessive use of kitchen
exhaust fans.
5. Do not permit the heat generated
by television, lamps, or radios to
influence the thermostat operation.
6. If you desire to operate your
system with constant air
circulation, please ask advice from
a qualified installer, service agency
or the gas supplier.
During the heating season the
operation of the warm air furnace is
automatic. Your qualified installer,
service agency or the gas supplier has
provided a wall mounted thermostat
which is sensitive to the change in
temperature of the air moving around
the thermostat. Your thermostat will
have switches to select some or all of
the following functions:
HEAT - Turns heating on when
temperature drops below the desired
temperature.
COOL - Turns cooling on when
temperature rises above the desired
temperature.
AUTO - Turns cooling or heating on as
required to maintain the desired
temperature.
OFF - Turns heating and cooling
modes off. (The blower may still run in
the FAN-ON position.)
FAN-ON - Turns the blower on for
continuous operation.
FAN-AUTO - The blower cycles on and
off with cooling or heating operation.

WARNING
IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR
EXPLOSION MAY RESULT CAUSING PROPERTY DAMAGE, PERSONAL
INJURY OR LOSS OF LIFE.
NOTE: Read and follow the Safety Information, Operating Instructions and
Instructions To Turn Off Gas To Appliance located on the furnace. This label
will have specific information regarding the furnace and its gas controls.
TYPICAL GAS CONTROL VALVE
A. Gas valves and controls vary in
appearance, but two basic types are
standard.
ELECTRIC IGNITION
The gas control lever or knob has
“ON” and “OFF” positions only (see
Figure 3). This furnace is equipped
with an ignition device which
automatically lights the burners. Do
not try to light the burners by hand.
• NFPA90B Installation of warm air
heating and air conditioning systems.
• The equipment has been evaluated in
accordance with the Code of Federal
Regulations, Chapter XX, Part 3280.
B. BEFORE OPERATING smell all
around the appliance area for gas. Be
sure to smell next to the floor because
some gas is heavier than air and will
settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance
• Do not touch any electric switch; do
not use any phone in your building.
• Immediately call your gas supplier
from a neighbor’s phone. Follow the
gas supplier’s instructions.
• If you cannot reach your gas
supplier, call the fire department.
