WELCOME TO A NEW GENERA TION OF
COMFORT
Congratulations! In light of rising energy costs, the 58UVB
WeatherMaker Infinity, Gas--Fired, Upflow, Condensing
Furnaces are 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, over 95%*
of the heat generated 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.

8. Air filter and retainer (location in furnace may vary).
9. Condensate drain connection. Collects moisture
condensed from burned gases for disposal into home drain
system. (Location in furnace varies.)
10. Heavy -- duty blower. Circulates air across the heat
exchangers to transfer heat into the home.
11. Secondary condensing heat exchanger (inside). Wrings
out more heat through condensation. Constructed with
polypropylene--laminated steel to ensure durability .
12. Primary serpentine heat exchanger (inside). Stretches fuel
dollars with the S-- shaped heat-- flow design. Solid
construction of corrosion--resistant aluminized steel means
reliability.
13. Furnace control board.
14. 3--amp fuse provides electrical and component protection.
15. Light emitting diode (LED) on furnace control board.
Status code light is for diagnosing furnace operation and
service requirements.
16. Pressure switch(es) ensure adequate flow of flue gas
through furnace and out vent system.
17. Rollout switch (manual reset) to prevent overtemperature.
18. Junction box for 115--v electrical power supply. (May be
located on right or left side)
19. Transformer (24v) behind furnace control board provides
low--voltage power to furnace control board and
thermostat.

SAFETY CONSIDERAT IONS
Recognize safety information. This is the safety--alert symbol
. 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, and
CAUTION. DANGER identifies the most serious hazards which
will result in severe personal injury or death. WARNING signifies
hazards which could result in personal injury or death.
CAUTION is used to identify unsafe practices which may result
in minor personal injury 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 furnace uses air from outside the home for
combustion and vents flue gas to the outdoors. It is not
to be installed using indoor air for combustion. The
vent pipe must terminate outside the structure and must
not be obstructed in 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.
S Do not cover the furnace, store trash or debris near it, or
in any way block the flow of fresh air to the unit.
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
or when insulation is added. Some materials may be
combustible.
S 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.

FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Do not keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.

FIRE AND UNIT OPERATION HAZARD
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 furnace is 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
sagging cracks, gaps, etc. around the base.
5. There are no obvious signs of deterioration of the furnace.
6. The burner flames are in good adjustment. (See Fig. 5.)

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 Never attempt to manually light the burners with a
match or other source of flame.
A92319
Fig. 6 -- Do Not Light Burner with Match
Steps For Starting Your Furnace
1. Set your room thermostat to the lowest temperature
setting. (See Fig. 7.)
2. Close the external manual gas valve. (See Fig. 8.)

S Read and follow the operating instructions on 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, STOP!
Follow “B” in the safety information above on this
furnace label. If you don’t smell gas, go to the next
step.
S If a suspected malfunction occurs with your gas control
system, such as the burners do not light when they
should, refer to the shutdown procedures on inside of
main furnace door, or in the “Shutting Down Your
Furnace” section and call your dealer as soon as
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.)
WARNING
A06188
Fig. 8 -- Close Valve
3. Turn OFF electrical supply to the furnace. (See Fig. 9.)
4. Remove main furnace door. (See Fig. 10.)
5. The gas valve will have a control switch to turn off and
on. Turn the control switch on the gas control to the OFF
position and wait 5 minutes. (See Fig. 11 or 12.) Then
smell for gas, including near the floor. If you smell gas,
STOP! Follow “B” on furnace label. If you don’t smell
gas, go to next step.
6. After waiting 5 minutes, turn the control switch on the gas
control to the ON position. (See Fig. 13 or 14.)
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:
