WELCOME TO A NEW GENERATION
OF COMFORT
Congratulations! In light of rising energy costs, the 58MSA Multipoise, Condensing Gas Furnace 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 2 heat exchangers to
“squeeze” out the maximum amount of heat from the fuel consumed. In fact, your new furnace is so efficient, 90% AFUE* of
the heat generated during combustion is captured and delivered
inside your home. That is more than a 33% AFUE* increase in
heating efficiency over conventional furnaces.
This furnace is among the most energy-efficient furnaces you can
buy today. It is also among the safest and most dependable. 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
precedures.

SAFETY CONSIDERATIONS
Recognize safety information. This is the safety-alert sym-
!
bol . 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. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which
WARNING signifies hazards which

To minimize the possibility of serious personal injury, fire,
furnace damage, or improper operation;
these safety rules:
Your gas furnace uses air adjacent to the furnace for combustion and vents to the outside. Do not enclose it in an airtight
room or seal it behind solid doors. It must have adequate airflow for efficient combustion and safe ventilation. The vent
pipe must terminate outside the structure and must not be
obstructed in any way.

would result in minor personal injury or product
will result in enhanced installation, reliability, or
carefully follow
many products around the home, such as: water softener
salts, laundry bleaches, detergents, adhesives, paints, varnishes, paint strippers, waxes, and plastics.
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.
• A furnace installed in an attic or other insulated space
must be kept free and clear of insulating material. Examine
the furnace area when the furnace is installed or when
insulation is added. Some insulation materials may be
combustible.
This furnace contains SAFETY DEVICES which must be
MANUALLY RESET. If the furnace is left unattended 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.
STARTING AND SHUTTING DOWN
YOUR FURNACE
Should the gas supply fail toshut off or if over heating occurs,
shut off gas valve to the furance before shutting of the electrical supply. 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.
safeguards:
Follow these important
• Keep the area around your furnace free of combustible
materials, gasoline, 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.
• Combustion air must be clean and uncontaminated with
chlorine or fluorine. These compounds are present in
3
• Never attempt to light the burners manually with a match
or other source of flame.
• Read and follow the operating instructions on the inside
of main furnace door, 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,
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 procedures on the inside of main furnace door, or in the “Shutting Down Your Furnace” section
