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.
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.
Your 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.
DESCRIPTION
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.

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.
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”
position. 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.
Immediately 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.

FURNACE MAINTENANCE SECTION
THE FURNACE CONTROLS AND THEIR FUNCTION
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 roof cap (if applicable).
2. The furnace vent pipe. Should it be necessary to service the vent/
air intake system, the manufacturer 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 burner, ignitor and flame sensor.

FURNACE CLEANING SECTION
NOTE: The cleaning operations listed below must be performed only by
a qualified service agency.
Burner Removal/Cleaning
The main burner should be checked periodically for dirt accumulation. If
cleaning is required, follow this procedure:
1.
Turn off the electrical power to the unit.
2.
Turn off the gas supply at the external manual shut-off valve and
loosen the ground union joint.
3.
Remove the upper access panel.
4.
Disconnect wires from flame sensor, rollout switch and HSI igniter.
Remove igniter carefully, as it is easily broken.

Limit Control - This furnace is protected by two (2) high temperature limit switches. The lower limit switch is an automatic reset
type.
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.
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.
Unitary Products Group

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.

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.

5 FLASH: Gas flow with no call for heat. Check gas valve and gas valve
wiring.
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.
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.
