It is the owner’s responsibility to ensure that an annual inspection of the
entire heating portion of the unit is made by a qualified service agency.
1. Examine the heat exchanger, vent/combustion air piping, vent
connectors and chimney to be sure they are clear and free of
obstructions.
2. Examine the vent pipe making sure it is firmly in place, that it
slopes slightly upward and is physically sound without holes and
all of the connections are secure.
3. Examine the return-air duct connections to make sure they are
physically sound, sealed to the furnace casing, and the ducts ter-
minate outside the space containing the furnace.
4. Examine the furnace casing making sure the physical support is
sound without sagging, cracks or gaps. Examine the furnace base
making sure it is physically sound without cracks, gaps or sagging
and has a good seal.
5. Examine the furnace casing for obvious signs of deterioration.

HOW YOUR GAS FURNACE WORKS
Your furnace is a very easy appliance to take for granted. Season after
season, it sits there in your home, keeping you warm and comfortable.
For this reason, you may never have given much thought to the way
your furnace operates. In order to get the safest and most efficient oper-
ation from your furnace, you should understand how your furnace does
its job.
When you set your thermostat to provide more heat in your home, you
are starting the heating cycle of the furnace. First, the inducer motor
starts to purge the heat exchanger of any remaining gases. Next, the
hot surface ignitor glows and after a warm-up period the gas valve
opens and ignition occurs. A short time later, the blower starts and dis-
tributes the warm air throughout the home. When the temperature set-
ting on your thermostat is reached, the gas valve closes, the main
burners are turned off, and the blower continues to run until the remain-
ing warm air in the system is distributed. When the blower stops, the
heating cycle has ended.
START-UP AND SHUTDOWN INSTRUCTIONS
Read the Instructions Below Before Trying to Start the
Furnace
A. This appliance does not have a pilot. It is equipped with an ignition
device which automatically lights the burner. Do not try to light the
burner by hand.
B. BEFORE OPERATING; smell all around the appliance area for
gas. Be sure to smell next to the floor because some gas is
heavier than air and will settle on the floor.
C. Use only your hand to push the gas control switch to the “on” posi-
tion. Never use tools. If the switch will not operate by hand, don’t
try to repair it, call a qualified service technician. Force or
attempted repair may result in a fire or explosion.
D. Do not use this appliance if any part has been under water. Imme-
diately call a qualified service technician to inspect the appliance
and to replace any part of the control system and any gas control,
which has been under water.
Operating Instructions:
1. STOP! Read the safety information above.
2. Set the thermostat to the lowest setting.
3. Turn off all electric power to the appliance.
4. Remove burner door.
5. Move gas control switch to the “OFF” position. Do not force. See
Figure 4.
6. Wait five (5) minutes to clear out any gas. If you then smell gas,
STOP! Follow “B” in the safety information above. If you don’t
smell gas, go to next step.
7. Move gas control switch to the “ON” position. Do not force. See
Figure 4.
8. Replace burner door.
9. Turn on all electric power to the appliance.
10. Set thermostat to the desired setting. Burner will light, which may
take 30-60 seconds.
11. After three (3) trials for ignition, if the appliance will not operate fol-
low the instructions, “TO TURN OFF THE APPLIANCE” and call
your service technician or gas supplier.
To Turn Off the Appliance:
1. Set the thermostat to lowest setting.
2. Turn off all electric power to the appliance if service is to be per-
formed.
3. Remove burner access panel.
4. Move gas control switch to the “OFF” position. See Figure 4.
5. Replace burner access panel.
NOTE: The spring-loaded safety cut-off switch, mounted under the
blower deck will automatically cut off the electrical power supply
to the furnace when the blower panel is removed. As a safety
precaution, all electrical power and the gas supply to the furnace
should be turned off before servicing.
FURNACE USER MAINTENANCE
Every time the filters are changed the following items should be visually
inspected:
• Check combustion air and vent pipe for blockage or leakage.
• Check all components to be sure they are in good condition and
that there are no obvious signs of deterioration.
• Check the drain lines to make sure there are no cracks or leaks.
If you do not follow these instructions exactly, a fire or
explosion may result causing property damage, personal
injury, and/or loss of life.
Should overheating occur, or the gas valve fail to shut off,
turn the external manual gas valve in the gas supply line to
the furnace to the “off” position and let the furnace cool off
before shutting off the electrical power supply. Refer to
Figure 5.
FIGURE 4: Gas Valve - White Rodgers
FIGURE 5: Gas Piping
Before proceeding, be sure the area is well ventilated. Turn
the thermostat OFF. If the blower is running, wait until it
stops automatically. Turn OFF the gas and electrical power
supplies to the furnace. Check all metal parts and surfaces
to be sure they have cooled to room temperature before
you begin.

• Check for dirt or lint on any surfaces or on components. Do not try
to clean any of the surfaces or components. Cleaning of the fur-
nace and its components must be done by a qualified service pro-
fessional.
If, during the inspection of your furnace, you find any of the following
conditions:
• Excessive amounts of dust and lint on components.
• Damaged or deteriorated components or surfaces.
• Leaks or blockage in the vent pipe passages.
• Water on any surface inside or outside of the furnace.
Do not operate the furnace, call a certified dealer / servicing contractor
to check and / or clean your furnace, or for more information if you have
questions about the operation of your furnace.
If all components appear to be in good operating condition, replace the
front panels. Turn ON the gas and electrical power supplies to the fur-
nace, and set thermostat to the desired temperature.
Air Filters
Dirty filters greatly restrict the flow of air and may cause damage to the
moving parts of the furnace. If the filters become clogged the heat
exchangers and blower motor could overheat resulting in a potentially
dangerous situation. The filters should be checked every 3 months. On
new construction, check the filters every week for the first four weeks
and every three weeks after that, especially if the indoor fan is running
continuously. When replacing the filter(s) you must use filters that are
the same size as those recommended in Table 1. Use the following pro-
cedure to determine the filter size. Never operate your furnace without a
suitable air filter.
1. Measure the furnace width and use that measurement to deter-
mine the cabinet width.
• A 14-1/2” wide cabinet is a “A” cabinet.
• A 17-1/2” wide cabinet is a “B” cabinet.
• A 21” wide cabinet is a “C” cabinet.
• A 24-1/2” wide cabinet is a “D” cabinet.
2. Locate the cabinet size on Table 1 then determine whether you
have a bottom or side return air duct using the following method.
a. If the return air filter is on the left or right side of the furnace it
is a side return
b. If the air filter is on the bottom of the furnace then you have a
bottom return.
C. If the air filters are on the bottom and the side of the furnace
then you have a bottom and side return. You must replace
both air filters. Table 1 will indicate 2 filters by using brackets
with the number two (2).
D. If the air filters are on both sides of the furnace then you have
a two sided return. You must replace both air filters. Table 1
will indicate 2 filters by using brackets with the number two
(2).
3. After you determine the cabinet size and what return configuration
you have, look up the recommended filter size from Table 1.
Removing Filters
Internally Mounted Air Filters
Most upflow furnaces have their filters located on the side or bottom of
the furnace in a filter wire retainer located inside the blower compart-
ment. To check filters located in the blower compartment:
1. Remove the upper furnace door by lifting up. Pull out bottom of
door and lower from furnace.
2. Remove the blower compartment panel by lifting up.
3. The filters will be located on the bottom or on one of the sides. To
remove bottom-mounted or side mounted filter (s) on all furnaces,
push the looped end of the filter retainer rod in, and then move the
retainer rod away from the filter.
4. Reverse the procedure to reinstall filters.
Externally Mounted Air Filters
Some installations may have the air filter in a rack attached to the cas-
ing of the furnace or placed in the return air duct. You can gain access
to the filter by pulling on the door or unscrewing the retaining screw,
then slide the filter(s) out of its channel. Replace throw away filter(s)
with the same size new filter(s). Throw away filter(s) may be replaced
with cleanable filter(s) at this time. Cleanable filter(s) may be cleaned as
described in the manufacturer instructions or as described below and
then re-installed.
To replace the filter after cleaning you must do the following:
1. Slide filter into place.
2. Snap the door on or place the door in position and tighten the
retaining screws, if provided.
3. Make sure the door is secure to the end of the filter rack.
How to Clean your Filter
High-velocity filters may be cleaned with a vacuum cleaner or washed
with a garden hose. Be sure to shake off excess water and allow filter to
completely dry before re-installing the filter.
Blower Care
Even with good filters properly in place, blower wheels and motors will
become dust laden after long months of operation. The entire blower
assembly should be inspected annually. If the motor and wheel are
heavily coated with dust, they can be brushed and cleaned with a vac-
uum cleaner. If the blower cannot be properly cleaned without removing
it from the furnace, then this service must be performed by a qualified
service agency.

SECTION II: SERVICE AND MAINTENANCE
MANUAL
SAFETY SECTION
The following safety rules must be followed when servicing the furnace.
FURNACE MAINTENANCE SECTION
The furnace should be cleaned and adjusted by a certified dealer or
qualified service contractor once a year or before the start of every
heating season. The following items must be cleaned and serviced or
replaced if there are signs of deterioration.
1. The vent terminal screen (if applicable).
2. The furnace vent and combustion air intake passageways. Should
it be necessary to service the vent/air intake system, the manufac-
turer recommends this service be conducted by a qualified service
agency. The operation of this appliance requires the reassembly
and resealing of the vent/air intake system.
3. The furnace burners, ignitor and flame sensor.
4. The condensate collection and disposal system. If any disassem-
bly of components containing flue or vent gases is required, a
qualified service agency must perform the service.
SEQUENCE OF OPERATION
The following describes the sequence of operation of the furnace. Refer
to Figure 1 for component location.
1. Call for 1st stage only
• On a call for 1st stage heat, the thermostat closes a circuit
between R and W1.
• The Microprocessor in the Furnace Control runs a ‘Self Check’.
• The Control checks the Primary Limit, Auxiliary Limit, and Roll-
out Switches for closed contacts.
• The Control checks that the Low Fire Pressure Switch (1LP) is
open.
• The Inducer Motor is energized on high speed, closing the con-
tacts of 1LP.
• The Control checks that 1LP is closed.
• The Inducer is switched to low speed.
• The Igniter is energized for 17 seconds.
• The Gas Valve is energized on 1st Stage (Low Fire).
• Flame Rectification is recognized within 7 seconds.
• 30 seconds after flame is proven, the ‘Heat Low’ relay is ener-
gized providing 120 Volts AC to the Blower Motor.
• At the same time, the EAC and Hum Hot relays are energized,
providing 120 Volts AC to the EAC Hot and Hum Hot terminals.
2. Call for 2nd Stage after 1st Stage is operating
• A call for 2nd Stage can be made by a 2-Stage thermostat, or by
the Second-Stage timer that comes installed in the furnace.
NOTE: When using a 2-Stage thermostat, the Timer should be discon-
nected.
• The Inducer Motor is shifted to high speed by the control, closing
the contacts of 2LP (The High Fire Pressure Switch.).
• The Control checks that 2LP is closed.
• The Gas Valve is energized on 2nd Stage (High Fire).
• The Control simultaneously de-energizes the Heat Low relay
and energizes the Heat High relay, providing 120 Volts AC to a
different speed of the Blower Motor.
3. 2nd Stage is satisfied, 1st Stage still calling.
• If a Single Stage Thermostat and the 2nd Stage Timer are used,
the Furnace will stay on High Fire until the thermostat is satis-
fied.
• When the circuit between R and W2 is opened, the Control
switches the Inducer Motor to low speed, causing the contacts of
2LP to open.
• When 2LP opens, 2nd Stage of the Gas Valve is de-energized.
• 30 seconds later, the Control switches the Blower from Heat
High to Heat Low.
4. 1st Stage Satisfied
• The Thermostat opens the circuit between R and W1
• Immediately the Gas Valve is de-energized and Flame Rectifica-
tion is lost.
• The Inducer Motor is de-energized after a 15 second Post Purge
and the Hum Hot terminal is de-energized.
• The ‘Fan Off Delay’ circuit is initiated. The Delay time can be
field set at 60, 90, 120, or 180 seconds. It comes from the fac-
tory set at 60 seconds.
• The Heat Low terminal is de-energized; stopping the Blower and
the EAC terminal is de-energized.
5. 1st and 2nd Stage called simultaneously
• The 1st stage call is processed as described in paragraph 1
above.
• Once Flame Rectification is established, 2nd Stage is entered
immediately as described in paragraph 2 above.
ELECTRIC SHOCK, FIRE OR EXPLOSION HAZARD
Failure to follow safety warnings exactly could result in
dangerous operation, serious injury, death or property
damage.
Improper servicing could result in dangerous operation,
serious injury, and death or property damage.
• Before servicing, disconnect all electrical power to the fur-
nace.
• When servicing controls, label all wires prior to discon-
necting. Reconnect wires correctly.
• Verify proper operation after servicing.

6Unitary Products Group
6. 1st and 2nd Stage satisfied simultaneously
• Both stages of the Gas Valve are de-energized.
• Flame Rectification is lost.
• The Inducer and Hum relays are de-energized after a 15-second
post purge.
• 30 seconds later the Control shifts the Blower from Heat High to
Heat Low.
• After the Blower-Off Delay Circuit is satisfied, the Blower and
EAC are de-energized.
7. Manual Fan Operation
• With the thermostat in the Fan On position, a circuit is completed
between R and G of the Control.
• The Heat Low and EAC relays are energized by the Control.
8. Call for Cooling
• The thermostat closes two circuits R to Y and R to G. Since the
Outdoor Unit is connected to Y and C at the Control, it is ener-
gized.
• The Cool and EAC relays are energized by the Control.
• A Blower-Off Delay Timing Circuit is energized by the call on Y.
9. Cooling call satisfied
• The thermostat opens the R to Y and R to G circuits.
• The Outdoor Unit is de-energized.
• The 60-second, Blower-Off Delay, timing circuit is initiated.
• After 60 seconds, the Cool and EAC relays are de-energized.
Heating Indoor Fan Off Delay
Changing the dipswitches on the Integrated Control can change the
indoor fan “OFF” time delay. The dipswitches are located above the
thermostat terminals. Refer to Figure 8 for the dipswitch settings to
obtain the desired fan OFF delay. The blower off delay must be long
enough to adequately cool the furnace, but not so long that cold air is
blown into the living space.
The blower on delay is fixed at 30 seconds and cannot be adjusted.
The continuous fan speed dipswitch (switch # 3 on the Integrated Con-
trol) does not function on variable speed models. Dipswitch # 3 should
be left in the off position.
Continuous Blower:
There are two modes of continuous blower operation.
•Mode One: The blower is controlled directly through the blower
motor. In the first mode, when the thermostat fan-switch is set to
the ON position a circuit is completed between terminals “R” and
“G” of the thermostat. The continuous fan speed will be 63% of
the high cool speed. If more air is desirable the green wire
labeled (G Cool Speed) may be connected to the “G” terminal of
the ignition control to achieve HIGH COOL speed (DIP switch
number 3 on the ignition control must be in the OFF position).
•Mode Two: The blower is controlled through the ignition control.
This configuration is used with multi-speed direct drive PSC
motors. Do not use this configuration with a variable speed
motor.Refer to Heating Indoor Fan Off Delay for Fan ON / OFF
Delays.
The air cleaner and the blower motor are energized through the ignition
control or directly through the motor.
DIRECT DRIVE BLOWER MOTOR
A failed PSC motor should always be replaced with a PSC motor suit-
able for the furnace model being serviced. Follow the procedure below
to replace the motor.
Removal of the Variable Speed Blower Motor Assembly:
The procedure for removing the variable speed blower assembly:
1. Disconnect the electrical supply to the furnace and remove the
access doors.
2. Remove blower assembly mounting screws and slide the blower
assembly out of the slots in the deck. If the two shipping screws
were not previously removed, also remove and discard these two
screws located on each front corner of the blower assembly.
3. Loosen the blower wheel set screw that secures the blower wheel
to the blower motor shaft.
4. Remove the motor mount bolts.
5. Slide the variable speed motor out of the blower housing.
Reassembly of the Variable Speed Blower Motor Assembly:
1. Slide the new variable speed motor in to the blower housing. Make
sure you line up the flat side on the motor shaft with the setscrew
on the hub in the center of the blower wheel.
2. Install the motor mount bolts in to the fan housing.
3. Center the indoor fan wheel in the fan housing and tighten the
blower wheel set screw on the flat side the blower motor shaft.
4. Reinstall blower assembly mounting screws and slide the blower
assembly back in the slots in the deck. Do not reinstall the two

the drain lines from the vent blower housing and from the conden-
sate drain pan. Remove the vent blower housing blower and the
condensate pan. The turbulators can then be gently removed from
the secondary heat exchanger.
3. Using a stiff wire brush, remove the loose scale or soot from each
tube.
4. Vacuum the secondary heat exchanger.
5. Finish the cleaning procedure by following steps 11 thru 13 under
cleaning the Heat Exchanger.
TROUBLESHOOTING
The following visual checks should be made before troubleshooting:
1. Check to see that the power to the furnace and the ignition control
module is ON.
2. The manual shut-off valves in the gas line to the furnace must be
open.
3. Make sure all wiring connections are secure.
4. Review the sequence of operation. Start the system by setting the
thermostat above the room temperature. Observe the system’s
response. Then use the troubleshooting section in this manual to
check the system’s operation.

HOT SURFACE IGNITION SYSTEM
Do not attempt to light this furnace by hand (with a
match or any other means). There may be a potential
shock hazard from the components of the hot surface
ignition system. The furnace can only be lit automatically
by its hot surface ignition system.
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and danger-
ous operation. Verify proper operation after servicing.

FURNACE DIAGNOSTICS
Control Module Fault Code Explanatios
1 Flash (Continuous Flash; 1 second on, 1 second off)
Reason: Flame sensed without a call for heat.
Effect: Blower and Inducer operate at Low Heat speed.
Causes: Gas Valve stuck open; Gas Valve is slow closing.
Incorrect wiring (Gas Valve is energized when it should
not be).
Defective ground, Flame rod shorted to ground.
2 Flash
Reason: Contacts of 1LP are stuck in the closed position. It must
first see an open circuit, then a closed circuit to ensure
safety.
Effect: Control will not continue the ignition process.
Causes: Incorrect wiring. (A jumper left in place across the
switch.).
A failed switch.
3 Flash (Part One; 1st Stage)
Reason: 1LP did not close at the beginning of the heat cycle.
Effect: Inducer operates on Low Heat speed. The Control will
not continue the ignition process.
Causes: Faulty Inducer
Blocked or restricted vent system.
Vent system that exceeds the specifications.|
Blocked condensate drain
Broken or leaking pressure switch tubing
Faulty 1LP
3 Flash (Part Two; 2nd Stage)
Reason: 2LP did not close within 30 seconds of a call for 2nd
Stage heat.
Effect: After 30 seconds the Control will enter a ‘Soft Lockout’
period, and the Inducer will be de-energized. After 3
minutes the Control will try again. The procedure will be
repeated if 2LP does not close.
Causes: Faulty Inducer.
Restricted vent system.
Vent system that exceeds specifications.
Blocked or restricted condensate drain.
Broken or leaking pressure switch tubing.
Faulty 2LP.
4 Flash
Reason: Open limit circuit. The limit circuit includes the Primary
Limit, Auxiliary Limit, and Rollout Switches.
Effect: Blower and Inducer operate at Low Heat speed. If the
open switch resets, the furnace will resume normal
operation.
Causes: Dirty Filter
Improperly sized duct system.
Incorrect blower speed selection
Incorrect firing rate
Faulty blower motor
Faulty Control
6 Flash
Reason: 1LP has opened five times during one call for heat.
Effect: Control enters ‘Soft Lockout’. It will automatically reset
and try again after 1 hour.
Causes: Restricted vent system
Vent system that exceeds specifications
High wind
7 Flash
Reason: Flame rectification could not be established
- Flame rectification must be maintained for 7 seconds
to be recognized by the control.
Effect: Control tries 3 times then goes into ‘Soft Lockout’.
- There is a 1-minute delay after a failed ignition
attempt
- 7 seconds is added to the igniter warm-up time after
a failed ignition attempt.
Causes: Faulty hot surface igniter
Contaminated flame rod.
Poor ground connection to furnace.
Reversed polarity to furnace
Moisture on flame sensing circuit
Low gas pressure
Faulty gas valve
8 Flash
Reason: Flame rectification has been lost 5 times, during 1 call
for heat, after it was recognized by the control.
- Flame rectification is recognized after 7 seconds of
burner operation.
Effect: Control goes into ‘Soft Lockout’ after the 5th attempt to
maintain combustion.
Causes: Restricted vent system.
Blocked or restricted condensate drain.
Foreign objects in the inducer housing.
LED on constantly
Reason: The control discovered an internal fault during its self-
check procedure.
Effect: All operations cease.
Causes: Voltage spikes.
Supply voltage is too high or low.
- Reset the control by breaking line voltage for 30
seconds.
Control failure.
Never bypass pressure switch to allow furnace opera-
tion. To do so will allow furnace to operate under poten-
tially hazardous conditions.
Do not try to repair controls. Replace defective controls
with UPG Source 1 Parts.
Never adjust pressure switch to allow furnace operation.
