6. NEVER…Store flammable materials of any kind near your fur-
nace. Gasoline, solvents, and other volatile liquids should be
stored only in approved containers outside your home. These
materials vaporize easily and are extremely dangerous.
7. NEVER
…Store cleaning materials near your furnace. Materials
such as bleaches, detergents, powdered cleansers, etc., can
cause corrosion of the heat exchangers.
8. NEVER
…Use the area around your furnace as a storage area for
items which could block the normal flow of air. This flow of air is
required for ventilation of the various furnace components.
FIRE OR EXPLOSION HAZARD
This furnace is designed and approved for use with Natural
Gas and (LP) Propane Gas ONLY. DO NOT BURN ANY LIQUID
FUEL OR SOLID FUEL IN THIS FURNACE.
Burning any unapproved fuel will result in damage to the furnace heat exchanger, which could result in Fire, Personal
Injury, and/or Property Damage.
While you are away
Your furnace is equipped with a safety device which will shut off the
supply of gas to the burner in case of malfunction. For this reason it is
never practical to assume that the furnace will operate unattended for a
long period of time, especially if there is a possibility of damage to your
property because of freezing. So, if you plan to be away from home,
arrange for someone to check your house every day.
This furnace shall be installed in the downflow position. Figure 1 shows
a typical model in the downflow position. The furnace is equipped with
an induced-draft vent blower and atmospheric burner. Combustion air is
drawn through the roof jack and pushed into the burner box. Flue gas is
forced from the heat exchanger by the vent blower and discharged
through the flue pipe to the outside atmosphere.
This is a forced air furnace. The furnace circulating air blower draws
cool air from the house, passes it over the hot furnace heat exchanger
and circulates the warmed air through the ductwork to the house.
The furnace is equipped with the controls necessary for proper operation. The various components referred to in this manual and on the furnace rating plate are identified in Figure 1.
SEASONAL SERVICE INFORMATION
During extreme cold weather, ice may form on the furnace roof jack
crown. Small amounts of ice forming on the roof jack will present no
problem to proper furnace operation. However, excessive ice formation
could restrict the combustion air supply to the burner causing inefficient
burner operation.
When the temperature is very cold, near zero or below, it is recommended that the roof jack be inspected every day or more frequently if
required. If ice has started to collect on the roof jack crown, it should be
carefully broken off.
Y our Service Technician
Your furnace's best friend is your qualified service technician. If the unit
gives any indication of improper operation, call your service technician.
If the service technician is allowed to perform the normal routine care of
your furnace, he can many times detect potential difficulties and make
corrections before trouble develops. Preventative maintenance of this
type will allow you to operate the unit with a minimum of concern, and at
the same time will pay for itself in added years of comfort.

GAS SUPPLY
The gas supply to your home will either be Natural Gas or Propane gas.
Your furnace will be factory equipped to operate on only one of these
two different gases.
A small metal tag secured to the furnace next to the gas valve will specify the type of gas your furnace is equipped to use.
If the gas is different from that specified on the metal tag, the furnace
can be converted by following the instructions on the furnace safety
label inside lower front panel. Parts for conversion are contained in the
small bag attached to the gas valve. Be sure the proper size orifice is
used, as specified on the furnace name plate.
The furnace must be converted by a qualified technician.
Improper conversion can cause unsafe operation, explosion,
and/or fire or asphyxiation.
Natural Gas Operation
The furnace is designed for 7" W.C. inlet pressure. Pressure is reduced
to 3 1/2" W.C. by the pressure regulator in the gas valve.
Propane Gas Operation
Inlet pressure to the gas valve must be 11" W.C. When properly converted to Propane gas, the pressure is regulated at 10" W.C.
INSTRUCTIONS FOR EXAMINING THE FURNACE
INSTALLATION
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.
Examine the furnace as outlined below in steps “1 - 6” before each
heating season.
1. Examine the heat exchanger, through an access panel located on
the supply air plenum. Visually examine the exterior sections of
the vent/combustion air piping and the vent connectors to be sure
that they are physically sound without holes or excessive corrosion.
2. Examine the vent pipe making sure it is firmly in place, and is
physically sound without holes and all of the connections are
secure.
3. Examine return connections for Modular or Manufactured (Mobile)
Homes.
4. Examine the return air filter rack connections to make sure they
are physically sound, sealed to the furnace door.
5. 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.
6. Examine the furnace casing for obvious signs of deterioration.
7. Examine the burner flames to make sure the burner look like they
are operating properly. The burner flames for natural gas should
appear blue with a few yellow tips. The burner flames for propane
gas should appear blue with moderate yellow tips. The flame
should appear cylindrical in shape and should extend from the end
of the burner into the heat exchanger.
FIGURE 2: Burner Flame Appearance
Observing Burner Operation
1. Observe burner to make sure it ignites. Observe color of flame. On
natural gas the flame will burn blue with appreciably yellow tips.
On Propane gas a yellow flame may be expected. If flame is not
the proper color call a qualified service technician for service.
2. Let furnace heat until blower cycles on.
3. Turn thermostat down.
4. Observe burner to make sure it shuts off.
5. Let the furnace cool and blower cycle off.
Should overheating occur, or the gas supply fail to shut off, shut off
the manual gas valve to the furnace and allow blower to run until
furnace cools down and blower shuts off before shutting off the
electrical supply.

FIGURE 3: Furnace Examination Checkpoints
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 operation 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 distributes the warm air throughout the home. When the temperature setting on your thermostat is reached, the gas valve closes, the main
burner is turned off, and the blower continues to run until the remaining
warm air in the system is distributed. When the blower stops, the heating cycle has ended.
IF FURNACE FAILS TO OPERATE PROPERLY
1. Check setting of thermostat - and position of heat/cool switch if air
conditioning is installed. If a set-back type thermostat is employed
be sure that the thermostat is in the correct operating mode.
2. Check to see that electrical power is “ON”.
3. Check to see that the lever or switch on the gas control valve is in
the full “ON” position.

FURNACE USER MAINTENANCE
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.
Every time the filters are changed the following items should be visually
inspected:
• Check roof jack assembly 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 evaporator coil drain lines to make sure there are no
cracks or leaks.
• 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 furnace and its components must be done by a qualified service professional.
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, and 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. Follow the operating instructions to place the furnace in
operation.
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 (DO NOT USE PLEATED
FILTER in this furnace). 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 and type as those in
the furnace (2 - 16 x 20 x1).
Removing Filters
Internally Mounted Air Filters
The air filter is in a rack that is attached to the door of the furnace.
To remove the filter you must do the following:
1. Before proceeding, be sure the area is well ventilated. Follow
instruction “To turn off the appliance”. Check all metal parts and
surfaces to be sure they have cooled to room temperature before
you begin.
2. Remove the filter door.
3. Remove the air filter by sliding it down the track. The air filter will
slide out of the rack.
4. 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 in these instructions.
129099-UUM-G-0909
To replace the filter after cleaning you must do the following:
1. Slide filter into place. If the filter has been cleaned, make sure it is
dry before re-installing it.
2. Replace the door or cover panel.
3. Make sure the door snaps into the retaining clips.
4. Follow the Operating Instructions to place the furnace back in
operation.
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 vacuum cleaner. If the blower cannot be properly cleaned without removing
it from the furnace, then call a qualified service agency. Only a qualified
service agency can perform this service.
Make sure you DO NOT move the clip on weight on the indoor
fan wheel when cleaning the wheel. This weight is used to
balance the wheel. Moving the weight will cause the fan wheel
to vibrate.
Motor Lubrication
The motors in these furnaces are permanently lubricated, and do not
require periodic oiling.

4. Remove the screws holding the burner assembly to the vestibule
panel and remove this assembly. Handle the assembly carefully
since it contains the igniter, which is fragile and easily broken. The
lower portion of the heat exchanger will now be exposed. Remove
any soot and scale. Vacuum loose soot, scale and dirt from the
heat exchanger.
5. After cleaning is complete, replace all components in reverse
order. Re-gasket all surfaces which required a gasket. Reconnect
all wiring. Reattach vent pipe and gas supply lines before restoring
service to furnace. Restore electrical power, check gas supply piping for leaks, and then verify furnace operation.
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
THE FURNACE CONTROLS AND THEIR FUNCTION
1. Limit Control - This furnace is protected by two (2) high temperature limit switches. The lower limit switch is an automatic reset
type.
2. Upper Limit Control - The upper limit switch near left side of
blower is a manual reset type limit switch. If burner does not function, turn system switch to “OFF” and push reset button in center
of limit switch.
3. Gas Valve - The gas valve is 100% shut-off type and will fail safe if
for some reason the gas is turned off. It is also of the snap opening
type which opens to fire position.

SEQUENCE OF OPERATION
Continuous Blower
On cooling/heating thermostats with fan switch, when the fan switch is
set in the ON position, a circuit is completed between terminals R and G
of the thermostat. The blower motor is energized through the cool fan
terminal on the ignition control module.
Intermittent Blower - Cooling
On cooling/heating thermostats with fan switch, when the fan switch is
set in the auto position and the thermostat calls for cooling, a circuit is
completed between the R, Y and G terminals. The motor is energized
through the cool fan terminal and runs on the selected speed. The fan
off setting is fixed at 60 seconds for SEER enhancement.
Heating Cycle
When the system switch is set on HEAT and the fan is set on AUTO,
and the room thermostat calls for heat, a circuit is completed between
terminals R and W of the thermostat. When the proper amount of combustion air is being provided, a pressure switch activates the ignition
control.
The ignition control provides a 30-second warm-up period. The gas
valve then opens for 10 seconds. If the flame is not detected within 2
seconds of the gas valve opening, the gas valve is shut off and a retry
operation begins. If the flame is lost for 2 seconds during the 10 second
stabilization period, the gas valve is shut off and a retry operation
begins. During a retry operation the ventor starts a 15 second interpurge and the ignitor warm-up time is extended to 27 seconds. If the
flame is established for more than 10 seconds after ignition, during a
retry, the control will clear the ignition attempt (retry) counter. If three
retries occur during a call for heat, the furnace will shut down for one
hour. If at the end of the one hour shut down there is a call for heat, the
furnace will initiate a normal start cycle. If the problem has not been corrected the furnace will again lockout after three retries.
A momentary loss of gas supply, flame blowout, or a faulty flame probe
circuit will result in a disruption in the flame and be sensed within 0.8
seconds. The gas valve will de-energize and the control will begin a
recycle operation. A normal ignition sequence will begin after a 15 second inter-purge. If during the three recycles the gas supply does not
return, or the fault condition is not corrected the ignition control will lockout for 60 minutes.
During burner operation, a momentary loss of power for 50 milliseconds
or longer will de-energize the gas valve. When the power is restored,
the gas valve will remain de-energized and the ignition sequence will
immediately restart.
As the gas starts to flow and ignition occurs, the flame sensor begins its
sensing function. If a flame is detected during the 10 second flame stabilization period the circulating blower will energize 30 seconds after the
gas valve opens (20 seconds after the flame stabilization period ends).
Normal furnace operation will continue until the thermostat circuit
between R and W is opened. When the thermostat circuit opens, the
ignition control is de-energized. When the ignition control is de-energized, the gas flow stops, and the burner flames are extinguished. The
ventor continues to operate for 15 seconds after the gas flow stops.
The blower motor continues to operate for the amount of time set by the
fan-off delay "Jumper" located on the ignition control board. Refer to
Figure 6. The heating cycle is complete, and the furnace is ready for the
start of the next heating cycle.

Hot Surface Ignition System
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.
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.
Never bypass pressure switch to allow furnace operation. To
do so will allow furnace to operate under potentially hazardous conditions.
Do not try to repair controls. Replace defective controls with
UPG Source 1 Parts.
Never adjust pressure switch to allow furnace operation.

FURNACE CONTROL DIAGNOSTICS
The furnace has built-in, self diagnostic capability. If a system problem
occurs, a fault code is shown by a blinking green LED. It is located
behind a clear view port in the blower compartment door. DO NOT turn
off furnace power as this action will clear the control's memory of the
fault.
The control continuously monitors its own operation and the operation
of the system. If a failure occurs, the LED will indicate the failure code. If
the failure is internal to the control, the light will stay on continuously. In
this case, the entire control should be replaced as the control is not field
repairable.
Flash sequence codes 1 through 6 are as follows: LED will turn “on” for
one second and “off” for one second. This pattern will be repeated the
number of times equal to the code. For example, six “on” flashes equals
a number 6 fault code.
All flash code sequences are broken by a 2 second “off” period.
IGNITION CONTROL
Normal flame sense current is approximately
3.7 microamps DC (a)
Low flame signal control lockout point is
0.9 microamps DC (a)
1 FLASH: Ignition failure.
2 FLASH: Combustion air pressure switch closed, this indicates that
the normally open pressure switch contacts are stuck in the closed position. The control confirms these contacts are open at the beginning of
each heat cycle. This would indicate a faulty pressure switch or mis-wiring.
3 FLASH: Combustion air pressure switch failed to close, this indicates
the normally open pressure switch contact did not close at the beginning of the heat cycle. This could be caused by a number of problems;
faulty inducer, blocked vent pipe, broken pressure switch hose or faulty
pressure switch.
4 FLASH: Limit Switch Open, this indicates that a primary or auxiliary
limit switch has opened its normally closed contacts. With this fault code
the control will operate the supply air blower and inducer. This condition
may be caused by: dirty filter, improperly sized duct system, incorrect
blower speed setting, incorrect firing rate or faulty blower motor.
5 FLASH: Gas flow with no call for heat. Check gas valve and gas valve
wiring.
RAPID FLASHES: Reverse Polarity, reverse polarity indicates reverse
line voltage polarity. Both heating and cooling will be affected. Check
polarity of both.
STEADY ON: Normal Operation.
60 MINUTE AUTOMATIC RESET FROM LOCKOUT: This control
includes a "watchdog" type circuit that will reset from a lockout condition
after 60 minutes. Operational faults 1, 3, 4 and Steady On will be reset.
This provides protection to an unoccupied structure if a temporary condition exists causing a furnace malfunction. An example would be a low
incoming gas supply pressure preventing unit operation. When the gas
pressure is restored, at some point the "watchdog" would restart the
unit and provide heat for the house.
NOTE: If a flame is detected the control flashes the LED for 1/8 of a
second and then enters a flame stabilization period.
