GENERAL INFORMATION
Understand the signal words WARNING and CAUTION.
These words are safety alert words. WARNING indicates
hazards which could result in personal injury or death.
CAUTION is used to indicate unsafe practices which could
result in minor injury or property damage.
IMPORTANT FACTS
The fl ow 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 airfl ow, thereby affecting effi ciency and safe operation of your furnace.
Also, air openings provided to the area in which the furnace
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 furnace. If additional insulation is added after the furnace is installed, the
area around the furnace must be inspected 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 fl ow of fresh air suffi cient for effi cient combustion and safe ventilation of your furnace.
The combustion air for your furnace must be fresh uncontaminated air. Paints, varnishes, laundry bleaches, detergents, many household cleaners, water softening salts,
adhesives, and all such products release fumes containing
compounds which could lead to early heat exchanger and
vent system deterioration. Do not store these types of products near your furnace.

WARNING
!
Never store gasoline, combustible materials, or other
fl ammable liquids or vapors near your furnace.
Carbon monoxide, fi re or smoke can cause serious bodily
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-fi red clothes
dryers, gas cooking stoves, water heaters, furnaces and
fi replaces. The U.S. Consumer Product Safety Commission
recommends that users of gas-burning appliances install
carbon monoxide detectors as well as fi re and smoke dectectors, listed by a nationally recognized agency (e.g. Underwriters Laboratories or International Approval Services), to
help alert dwelling occupants of the presence of fi re, 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.
SAFETY HAZARD
BODILY INJURY CAN RESULT FROM HIGH VOLTAGE
ELECTRICAL COMPONENTS, FAST MOVING FANS, AND
COMBUSTIBLE GAS. FOR PROTECTION FROM THESE
INHERENT HAZARDS DURING INSTALLATION AND SERVICING, THE ELECTRICAL SUPPLY MUST BE DISCONNECTED AND THE MAIN GAS VALVE MUST BE TURNED
OFF. FAILURE TO FOLLOW THIS WARNING MAY RESULT
IN PERSONAL INJURY, PROPERTY DAMAGE, OR DEATH.
Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and
qualifi ed personnel should install, repair or service heating
equipment.
Untrained personnel can perform basic maintenance functions such as cleaning and replacing fi lters. All other operations must be performed by trained service personnel.
Parts and controls of this furnace are unique. Should service or modifi cation be required, be sure your servicer uses
only factory authorized parts, kits, or accessories 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
Reduces Energy Use
AIR FILTERS
NOTE: Filters are NOT included with all Furnaces
A clean fi lter saves money.
When the furnace circulates and fi lters the air in your
home, dust and dirt particles build up on the fi lter. Excessive accumulation can block the airfl ow, 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 running
with a dirty fi lter.
Never operate your unit for either heating or cooling with
fi lters removed.
Help ensure top effi ciency by cleaning the fi lter once a
month. Clean it twice a month during seasons when the
unit runs more often.
Your fi lter may or may not be framed.
You can clean the fi lter with a vacuum, OR you can wash it
with a household detergent.
Both methods are quick and easy, and guaranteed to improve the performance of your system.
Replacing your fi lter.
When replacing your furnace fi lters, always use high velocity type which are the same size as originally supplied.
Filters are available from your dealer.
Where disposable fi lters are used, they must be a high velocity type which are the same size as originally supplied.

front of the unit. After cleaning, replace the fi lter in the
same manner making sure that the fi lter wire is secured
in place in both front and back fi lter retaining brackets.
Replace blower access door.
A bottom return air inlet as shown features a 17" x 25" x 1"
fi lter in the 17-1/2" wide furnace cabinets; a 20" x 25" x 1"
fi lter in the 21" wide models; and a 24" x 25" x 1" fi lter in
the 24-1/2" wide cabinet.
For vertical UPFLOW ONLY, a left or right return air inlet
as above (left side shown) requires trimming of the factory
supplied fi lter to 17" x 25" x 1" for both the 21" and 24-1/2"
wide furnaces.
Air fi lters may also be located outside of the furnace using a
SIDE FILTER FRAME.
How to remove your fi lter.
