WELCOME TO A NEW GENERATION
OF COMFORT
Congratulations! In light of rising energy costs, the Plus95s
Gas--Fired, Modulating Condensing Furnaceis among the wisest
investment today’s homeowner can make.
Your new furnace is truly a triumph of technology in home
heating. A revolutionary design employs two heat exchangersto
maximize the amount of heat from the fuel consumed. In fact,
your new furnaceis so efficient, up to95%* of the heatgenerated
during combustion is captured and delivered inside your home.
That is more than a 33%* increase in heating efficiency over
conventional furnaces.
These are among the most energy--efficient furnaces you can buy
today. They also are among the safest and most dependable. We
are proud of the technological advances incorporated into the
design of these furnaces. 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
Recognize safety information. This is the safety--alert symbol
. When you seethis symbol on the furnaceand ininstructions
or manuals, be alert to the potential for personal injury.
Understand the signal words: DANGER, WARNING, and
CAUTION. DANGER identifiesthe most serious hazards which
will result in severe personalinjury ordeath.WARNING signifies
hazards which could result in personal injury or death.
CAUTION is used to identify unsafe practices which may result
in minor personalinjury 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,
furnace damage, or improper operation; carefully follow these
safety rules:
S Your gas furnaceusesairfrom outside the homefor
combustion andventsfluegasto the outdoors. It is not
to be installedusingindoorairfor combustion. The
ventpipe must terminate outsidethe structure and must
not be obstructedin any way. The air- intake pipe must
terminate outside the structure or in a well ventilated
area that is isolated from the living space and the garage
(e.g. well ventilated attic or crawlspace). Do not block
or obstruct air openings on furnace or spaces around
furnace.
or when insulation is added. Some materials may be
combustible.
S This furnace contains SAFETY DEVICES which must
be MANUALLYRESET. Ifthe furnaceis left
unattended for an extended period oftime,haveit
checked periodically for properoperation.This
precaution will prevent problems associated with no
heat, such as frozen water pipes, etc. See “Before You
Requesta Service Call” sectionin this manual.

!
FIRE AND UNIT OPERATIONHAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
For proper and safe operation the furnace needs air for
combustion and ventilation. Do not block or obstruct
the openings on the furnace, air openings to the area in
which the furnaceis installed, and the space around the
furnace.

BEFORE STARTING YOUR FURNACE
Examine the furnace installation monthly 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 excessive corrosion.
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
saggingcracks, gaps,etc. around the base.
5. There are no obvious signsof deterioration of the furnace.
6. The burnerflames arein good adjustment. (SeeFig. 5.)
S Do not cover the furnace, store trash or debris near it, or
in any wayblockthe flow of fresh air to theunit.
S 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

STARTING AND SHUTTING DOWN
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 starts
your furnace. Follow these important safeguards:
S Neverattempt to manually light the burnerswith a
match or other source of flame.
A92319
Fig. 6 -- Do Not Light Burner with Match
S Readand follow the operatinginstructionson insideof
mainfurnace door, especially the item that readsas
follows:
Wait5 minutes to clear out any gas. Then smell for gas,
including nearthe floor. Ifyou smell gas,STOP!
Follow“B” in the safety information aboveon this
furnace label.Ifyou don’tsmell gas,go tothe next
step.
S Ifa suspected malfunctionoccurswithyourgas control
system, such as theburners do not light when they
should,refer to theshutdownprocedures on insideof
mainfurnace door, or in the “Shutting Down Your
Furnace” section and call yourdealeras soonas
possible.

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. (See Fig. 8.)

Follow “B” on furnacelabel.If you don’t smell gas, go to
next step.
6. After waiting 5 minutes, turn the control switch on the gas
controlto the ON position. (See Fig. 12.)
S CHECK AIR FILTER: Before attempting to start
your furnace, be sure the furnace filter is clean and in
place. See “Performing Routine Maintenance” section
in this manual. Then proceed as follows:
Steps For Starting Your Furnace
1. Set your room thermostat to the lowest temperature
setting. (SeeFig. 7.)
2. Close the external manual gas valve.(SeeFig. 8.)
