SULT IN PROPERTY DAMAGE, PERSONAL INJURY OR
DEATH.
▲CAUTION
!
If the furnace is shut down during the cold weather
months, provisions must be taken to prevent freeze-up
of all water pipes and water receptacles.
▲CAUTION
!
Do NOT touch igniter. It is extremely hot.
▲CAUTION
!
The furnace area must be kept clear and free of com-
bustible materials, gasoline, and other flammable
vapors and liquids.
▲CAUTION
!
Insulating materials may be combustible. The furnace
must be kept free and clear from insulating material.
Examine the area around the furnace for insulation
after installation or when insulation is added.
IMPORTANT FACTS
The flow of combustion and ventilating air must not
be obstructed from reaching the furnace. Air openings
provided in the casing of the furnace must be kept free
of obstructions which would restrict airflow, thereby af-
fecting efficiency and safe operation of your furnace.
Also, air openings provided to the area in which the fur-
nace is installed and the space around the furnace shall
not be blocked or obstructed. Keep this in mind should
you choose to remodel the area which contains your fur-
nace. If additional insulation is added after the furnace
is installed, the area around the furnace must be in-
spected to ensure it is free and clear of insulation. If this
furnace is installed in an attic or other insulated space
it must be kept free and clear of all insulating materials
as some insulating materials are combustible.
Furnaces must have air for proper performance. There
must be a free flow of fresh air sufficient for efficient
combustion and safe ventilation of your furnace.
Never store gasoline, combustible materials, or
other flammable liquids or vapors near your fur-
nace.
Carbon monoxide, fire or smoke can cause serious bodi-
ly injury, death, and/or property damage.
A variety of potential sources of carbon monoxide can
be found in a building or dwelling such as gas-fired
clothes dryers, gas cooking stoves, water heaters, fur-
naces and fireplaces. The U.S. Consumer Product Safe-
ty Commission recommends that users of gas-burning
appliances install carbon monoxide detectors as well as
fire and smoke detectors, listed by a nationally recog-
nized agency (e.g. Underwriters Laboratories or Inter-
national Approval Services), to help alert dwelling oc-
cupants of the presence of fire, smoke or unsafe levels
of carbon monoxide.
NOTE: The manufacturer of your furnace does not test
any detectors and makes no representations regarding
any brand or type of detector.
Installing and servicing 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 filters. All
other operations must be performed by trained service
personnel.
Parts and controls of this furnace are unique. Should
service or modification be required, be sure your ser-
vicer uses only factory authorized parts, kits, or acces-
sories for this furnace.
If you experience a problem with the operation of your
furnace, check the “Problem Solver” section of this
manual before you call for a possibly unneeded service
call.

Proper Maintenance
A clean filter saves money.
When the furnace circulates and filters the air in your
home, dust and dirt particles build up on the filter. Ex-
cessive accumulation can block the airflow, forcing the
unit to work harder to maintain desired temperatures.
And the harder your unit has to work, the more energy
it uses. So you pay more any time your system is run-
ning with a dirty filter.
▲CAUTION
!
Never operate your unit for either heating or cooling
with filters removed.
Help ensure top efficiency by cleaning the filter once
a month. Clean it twice a month during seasons when
the unit runs more often.
You can clean the filter with a vacuum, OR you can
wash it with a household detergent.
NOTE: Not all aftermarket filters can be washed with
a household detergent. See the instructions supplied
by the aftermarket filter manufacturer.
How to remove your filter.
▲WARNING

COULD RESULT IN PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.
Upflow furnaces use a high velocity type air filter
which may be located within the furnace blower com-
partment in either a BOTTOM or SIDE (left or right)
return air inlet. The filter may be secured with filter
retaining brackets (as shown) or a filter rack.
To clean or replace filters, remove blower access door,
slide the filter from the filter rack or remove the filter
from the retaining brackets. After cleaning, replace the
filter in the same manner, making sure that the filter
is secured in place in both the front and back filter re-
taining brackets, if present, or that the filter is secure-
ly slid all the way into the filter rack. Replace blower
access door. A bottom return air inlet as shown fea-
tures a 17" x 25" x 1" filter in the 17-1/2" wide furnace;
cabinets; a 20" x 25" x 1" filter in the 21" wide models;
and a 24" x 25" x 1" filter in the 24-1/2" wide cabinet.
When replacing your furnace filters, always use a high
velocity type which are the same size as originally sup-
plied. Filters are available from your dealer.
Where disposable filters are used, they must be a high
velocity type which are the same size as originally sup-
plied.
AIR FILTERS
Clean the filter once a month for optimum perfor-
mance. A monthly visual inspection of the furnace
is also recommended. See General Inspection
on page 9, number 1.
NOTE: Filters are NOT included with all Furnaces, how-
ever; the Furnace should never be run without a filter.

1. GENERAL INSPECTION – Examine the furnace
installation for the following items:
a. All flue product carrying areas external to the
furnace (i.e. chimney, vent connector) are clear
and free of obstruction.
b. The vent connector is in place, slopes upward
and is physically sound without holes or exces-
sive corrosion.
c. The return air duct connection(s) is physically
sound, is sealed to the furnace and terminates
outside the space containing the furnace.
d. The physical support of the furnace should be
sound without sagging, cracks, gaps, etc.,
around the base so as to provide a seal between
the support and the base.
e. There are no obvious signs of deterioration of
the furnace.
f. The burner flames are in good adjustment
without erratic flames. See illustation on page
10.
g. Fresh air inlet and vent are not blocked and
free from obstruction. The horizontal or verti-
cal vent and inlet must be located at least 12
inches minimum (18 inches in Canada) above
the normally expected snow accumulation
level.
Contact your service agent if you feel you are un-
comfortable performing any of the inspections not-
ed in section 1.
2. BLOWERS – The blower size and speed deter-
mine the air volume delivered by the furnace. The
blower motor bearings are factory lubricated and
under normal operating conditions usually do not
require servicing. Annual cleaning of the blower
wheel and housing is recommended for maximum
air output, and this must be performed only by a
qualified servicer or service agency.
The following warning complies with State of California law, Proposition 65.

�
WARNING
!
To ensure proper operation of your furnace, the rec-
ommended dealer inspection is once a year, before
the heating season. Regular maintenance must be
performed by a qualified service professional.
The servicer should perform steps 1-9 once a year
before the heating season.
The homeowner should perform the visual inspection
in step 1 monthly when cleaning the furnace filter.
Unless it is an emergency, never stop the heating
system by shutting off the main power.
If the main power to your air conditioner is ever dis-
connected for more than three hours, turn off the ther-
mostat. Then wait for at least three more hours after
the power has been restored before turning the ther-
mostat back on. Failure to follow this procedure could
result in damage to your furnace.

3. IGNITER – This unit has a special hot surface di-
rect ignition device that automatically lights the
burners. Please note that it is very fragile and
should be handled with care.
4. BURNER – Gas burners do not normally require
scheduled servicing, however, accumulation of for-
eign material may cause a yellowing flame or de-
layed ignition. Either condition indicates that a ser-
vice call is required. For best operation, burners
must be cleaned annually using brushes and
vacuum cleaner.
Turn off gas and electric power supply. To clean burn-
ers, remove top burner bracket and lift burner from
orifice.
NOTE: Be careful NOT to break igniter when removing
burners.
Clean burners with brush and/ or vacuum cleaner. Re-
assemble parts by reversal of the above procedure.
NOTE: On LP (propane) units, some light yellow tipping
of the outer mantle is normal. Inner mantle should be
bright blue. Natural gas units should not have any yel-
low tipped flames. This condition indicates that a ser-
vice call is required. For best operation, burners must
be cleaned annually using brushes and vacuum clean-
er.
NOTE: On LP (propane) units, due to variations in BTU
content and altitude, servicing may be required at
shorter intervals.
5. HEAT EXCHANGER / FLUE PIPE – These items
must be inspected for signs of corrosion, and/ or de-
terioration at the beginning of each heating season
by a qualified service technician and cleaned annu-
ally for best operation.
6. CIRCUIT PROTECTION – If blower or gas valve
fail to operate, the cause could be the circuit break-
er or a loose or blown fuse. Replace fuse or reset
circuit breaker.
FLAME
7. OPERATION – Your warm air furnace should not
be operated in a corrosive atmosphere. Paint sol-
vents, cleaning chemicals, spray propellants, and
bleaches should not be used in the vicinity of the
furnace during normal operation.
8. CONDENSATE DRAINS – If you have a cooling
coil installed with your furnace, condensate drains
should be checked and cleaned periodically to as-
sure that condensate can drain freely from coil
to drain. If condensate cannot drain freely water
damage could occur. Furnace drain should also be
checked & cleaned at the start of each heating sea-
son.
9. AIR CIRCULATION – To ensure increased com-
fort, the blower on this unit may be operated con-
tinuously for both heating and cooling. This will
result in constantly filtered air and aid in main-
taining more even temperatures by avoiding tem-
perature stratification throughout the conditioned
area. To accomplish constant air circulation, set
your comfort control fan selector to “ON”. Continu-
ous fan mode during COOLING operation may not
be appropriate in humid climates. If the indoor air
exceeds 60% relative humidity or simply feels un-
comfortably humid, it is recommended that the fan
only be used in the "AUTO" mode.”

This limited warranty is provided by the manufacturer to the original purchaser and to any succeeding owner of the real property to which the gas
furnace is originally affixed, and applies to products purchased and retained for use within the U.S.A. and Canada.
Beginning on January 1, 2010, R-22 refrigerant will no longer be used as a manufacturer-installed refrigerant as required by federal regulation.
Following this date, depending on the availability of any remaining R-22 equipment, indoor model replacements may require that the entire system
be R-410A compatible. Outdoor system components and possibly connecting line sets would need to be replaced in order to be compatible with
indoor units containing R-410A refrigerant. Expenses associated with replacing system components that are not R-410A compatible will not be
covered by the terms and conditions of the limited warranty.
The limited warranty period begins when installation is complete and the gas furnace start-up procedure has been properly completed, verified by
installer’s invoice or similar document. If installation completion and start-up date cannot be verified by installer’s invoice or similar document, this
limited warranty coverage begins six (6) months after the date of manufacture based on the gas furnace serial number.
If any functional part of your gas furnace fails because of a manufacturing defect within five (5) years from the date the limited warranty period
begins, Warrantor will furnish without charge the required replacement part. Any other costs, such as local transportation, related service labor,
diagnosis calls, refrigerant and related items are not included.
In addition, if the heat exchanger fails because of a manufacturing defect within the sixth through twentieth year from the date the limited warranty
period begins, Warrantor WILL AT ITS OPTION provide either a heat exchanger without charge, or allow a credit in the amount of the then current
wholesale price of an equivalent heat exchanger toward the purchase price of a comparable heating unit. Any other costs, such as local
transportation, related service labor, diagnosis calls, refrigerant and related items are not included.
This limited warranty does not apply if the gas furnace was purchased direct (i.e. from internet websites or auctions) on an uninstalled basis.
Additionally, this limited warranty will not apply unless the gas furnace is: (1) installed by a licensed or qualified HVAC technician, (2) applied and
installed in accordance with the manufacturer’s recommendations in its Installer’s Guide, and (3) in compliance with all industry standards,
national, state, and local codes.
This limited warranty does not cover failure of your furnace if it is damaged while in your possession; including, but not limited to (1) damage
caused by unreasonable use, (2) damage from failure to properly maintain as set forth in the Use and Care manual, (3) damage that is not
considered a manufacturing defect, such as acts of God, malfunctions or failures resulting from fire, water, storms, lightning, earthquake, theft, riot,
misuse, abuse, increased utility usage costs, or (4) performance problems due to improper selection/equipment match, installation or application.
This limited warranty applies to product installed on or after 5/1/2009.
Registered Limited Warranty Option
If registered within 60 days of the original installation date, the limited warranty terms will be lengthened** as follows: heat exchanger – lifetime, all
other functional parts – ten (10) years.
**Registered Limited Warranty lengthened terms only apply to owner occupied properties and single family properties on a US military installation,
are non-transferable and do not apply to income property.
To register, go to the manufacturer’s website or contact your dealer.
