NORMAL SEQUENCES OF OPERATION

Heating
This unit is equipped with an ignition control that automatically lights the main burner. DO NOT attempt to light the main burners by any other method.

1. R and W thermostat contacts close, initiating a call for heat.

2. Integrated control module performs safety circuit checks.

3. Inducer draft blower is energized for 30 second prepurge period causing pressure sensor contacts to close.

4. At the end of pre-purge period, integrated control module transitions the induced draft blower to light-off setting.

5. Once the light-off pressure setting is verified by the integrated control module, the spark igniter and gas valve are energized for 4 seconds.
   NOTE: The igniter produces a very intense electrical spark that ignites the gas.

6. Integrated control module monitors flame presence. Gas valve will remain open only if the flame is detected

7. The 5-second HEAT FAN ON delay time begins after main burner lights.

8. The unit delivers heat to the conditioned space until the thermostat is satisfied; integrated control module monitors safety circuits continuously

9. R and W thermostat contacts open, completing the call for heat; gas valve de-energizes.

10. Induced draft blower keeps operating for 30-second post purge.

11. Ignition control begins timing the HEAT FAN OFF delay. There is an adjustable HEAT FAN OFF delay of approximately 90/120/150/180 seconds (factory set at 150).

NOTE: This delay allows any additional heat in the heat exchanger to be transferred to the conditioned space. After the HEAT FAN OFF delay time has elapsed, the blower will de-energize.
Cooling

1. Thermostat calls for low or high stage cooling.
2. If the thermostat call is for low stage cooling, the compressor and outdoor fan are energized at low stage. If the thermostat call is for high stage cooling, the compressor and outdoor fan are energized at high stage.
3. The indoor blower will energize approximately 6 seconds later
4. The unit delivers cooling to the conditioned space until the thermostat is satisfied.
5. The compressor and outdoor fan will be de-energized when the thermostat opens.
6. The indoor blower continues to run at low cool speed for approximately 60 seconds after the thermostat is satisfied. This allows additional cooling from the indoor coil to be transferred to the conditioned space. Then, the indoor blower is de-energized.

NOTE: A 180-second anti-short cycle is integral to the control and prevents recycling of the compressor.
Fan Only

1. Thermostat calls for FAN ONLY by energizing “G”.
2. Indoor blower is energized at fan only speed.
3. The indoor blower is immediately de-energized once thermostat call for FAN is removed.

STARTUP, ADJUSTMENTS, AND CHECKS

Heating Startup
This unit is equipped with an electronic ignition device to automatically light the main burners. It also has a power vent blower to exhaust combustion products.
On new installations, or if a major component has been replaced, the operation of the unit must be checked.
Check unit operation as outlined in the following instructions. If any sparking, odors, or unusual sounds are encountered, shut off electrical power and check for wiring errors, or obstructions in or near the blower motors. Duct covers must be removed before operating unit.
Burner Limit Control
The burner temperature switch is mounted on the burner box assembly to monitor the burner box temperature. It is normally closed (electrically), auto-reset sensor. An input
to the control is provided by the normally closed blocked burner switch. An open blocked burner switch interrupts current to the gas valve which closes the valve. This switch guards against the burner flames not being properly drawn into the heat exchanger.
Secondary Limit Control
The secondary limit control is located on the top of the blower scroll assembly. This control opens when elevated temperatures are sensed. Elevated temperatures at the
control are normally caused by blower failure. The reason for the opening should be determined and repaired prior to resetting.
If the power to the unit is interrupted during the heating cycle, it may cause the secondary limit to trip. Once the blower compartment temperature drops below the limit
reset temperature, the limit will automatically reset.

Pre-Operation Checks

1. Close the manual gas valve external to the unit.
2. Turn off the electrical power supply to the unit.
3. Set the room thermostat to its lowest possible setting.
4. Remove the heat exchanger door on the side of the unit by removing screws.
5. This unit is equipped with an ignition device which automatically lights the main burner. DO NOT try to light burner by any other method.
6. Move the gas control valve switch to the OFF position. Do not force.
7. Wait five minutes to clear out any gas
8. Smell for gas, including near the ground. This is important because some types of gas are heavier than air. If you have waited five minutes and you do smell gas, immediately follow the warnings near the beginning of this manual. If having waited for five minutes and no gas smell is noted, move the gas control valve switch to the ON position.
9. Replace the heat exchanger door on the side of the unit.
10. Open the manual gas valve external to the unit.
11. Turn on the electrical power supply to the unit.
12. Set the thermostat to desired setting.

Gas Supply And Manifold Check
Gas supply pressure and manifold pressure with the burners operating must be as specified on the rating plate.
Gas Supply Pressure Measurement
NOTE: Use adapter kit #0151K00000S to measure gas pressure on White- Rodgers 36J22Y gas valves.
CAUTION
To prevent unreliable operation or equipment damage, the inlet gas supply pressure must be as specified on the unit rating plate with all other household gas fired appliances operating.
The line pressure supplied to the gas valve must be within the Inlet Gas Supply Pressure range specified. The supply pressure can be measured at the gas valve inlet pressure tap or at a hose fitting installed in the gas piping drip leg. The supply pressure must be measured with the unit OFF. To measure inlet pressure, use the following procedure.

1. Turn OFF gas to furnace at the manual gas shutoff valve external to the furnace.

11. Retest for leaks. If bubbles form, shut down gas and repair leaks immediately.

12. If there are no leaks, turn ON electrical power and gas supply to the system.

13. Turn valve switch ON.

NOTE: If measuring gas pressure at the drip leg, a field-supplied hose barb fitting must be installed prior to making the hose connection. If using the inlet pressure Tap on the White-Rodgers gas valve, then use the 36G/J Valve Pressure Check Kit, Goodman Part No. 0151K00000S.

Gas Manifold Pressure Measurement and
Adjustment
CAUTION
To prevent unreliable operation or equipment damage, the gas manifold pressure must be as specified on the unit rating plate. Only minor adjustments should be made by adjusting the gas valve pressure regulator.
Only small variations in gas pressure should be made by adjusting the gas valve pressure regulator. The manifold pressure must be measured with the burners operating.
To measure and adjust the manifold pressure, use the following procedure.

1. Turn OFF gas to furnace at the manual gas shutoff valve external to the furnace.

2. Turn OFF all electrical power to the system.

3. Outlet pressure tap connections:
   a. White-Rodgers Valve: Back outlet pressure test screw (outlet pressure Tap) out one turn (counterclockwise, not more than one turn).

4. Connect manometer (or appropriate pressure gauge) at the gas valve outlet pressure tap. See WhiteRodgers 36J22Y-204 gas valve for location of outlet pressure tap.

5. Turn ON the gas supply.

6. Turn ON power and close thermostat “R” and “W” contacts to provide a call for heat.

7. Using a leak detection solution or soap suds, check for leaks at outlet pressure tap screw (White-Rodgers valve). Bubbles forming indicate a leak. SHUT OFF GAS AND REPAIR ALL LEAKS IMMEDIATELY!

8. Measure the gas manifold pressure with burners firing. Adjust manifold pressure using the following Manifold Gas Pressure table.
   White-Rodgers Model 36J22 Connected to Manometer

12. Replace outlet pressure tap:
    a. White-Rodgers Valve:
    Turn outlet pressure test screw in to seal pressure port (clockwise, 7 in-lb minimum).

13.  Turn ON electrical power and gas supply to the system.

14.  Close thermostat contacts to provide a call for heat.

15. Retest for leaks. If bubbles form, SHUT OFF GAS AND REPAIR ALL LEAKS IMMEDIATELY!

Gas BTU Input (Natural Gas Only) Check
To measure the gas input use a gas meter and proceed as follows:

1. Turn off gas supply to all other appliances except the unit.

2. With the unit operating, time the smallest dial on the
   meter for one complete revolution. If this is a 2 cubic foot dial, divide the seconds by 2; if it is a 1 cubic foot dial, use the seconds as is. This gives the seconds per cubic foot of gas being delivered to the unit.

3.  INPUT=GAS HTG VALUE x 3600 / SEC. PER CUBIC FOOT
   Example: Natural gas with a heating value of 1000 BTU per cubic foot and 36 seconds per cubic foot as determined by
   Step 2, then:
   Input = 1000 x 3600 / 36 = 100,000 BTU per Hour.
   NOTE: BTU content of the gas should be obtained from the gas supplier. This measured input must not be greater than shown on the unit rating plate.

4. Relight all other appliances turned off in step 1. Be sure all pilot burners are operating.

Temperature Rise Check
Check the temperature rise through the unit by placing thermometers in supply and return air registers as close to the unit as possible. Thermometers must not be able to
sample temperature directly from the unit heat exchangers, or false readings could be obtained.

1. All registers must be open; all duct dampers must be in their final (fully or partially open) position and the unit operated for 15 minutes before taking readings.
2. The temperature rise must be within the range specified on the rating plate.

Checking Temperature Rise
NOTE: Air temperature rise is the temperature difference between supply and return air.
With a properly designed system, the proper amount of temperature rise will normally be obtained when the unit is operated at rated input with the recommended blower
speed.
If the correct amount of temperature rise is not obtained, it may be necessary to change the blower speed. A higher blower speed will lower the temperature rise. A slower
blower speed will increase the temperature rise.
NOTE: Blower speed MUST be set to give the correct air temperature rise through the unit as marked on the rating plate.
External Static Pressure Check
The total external static pressure must be checked on this unit to determine if the airflow is proper.

1. Using a digital manometer measure the static pressure of the return duct at the inlet of the unit (Negative Pressure).

2. Measure the static pressure of the supply duct (Positive Pressure).

3. Add the two readings together.
   NOTE: Both readings may be taken simultaneously and read directly on the manometer is so desired.

4. Consult proper table for quantity of air.

If the external static pressure exceeds the minimum or maximum allowable statics, check for closed dampers, dirty filters, undersized or poorly laid out ductwork.
Blower Speed Adjustments
WARNING
To avoid personal injury or death due to electric shock, remove electrical power from the unit before changing speed taps on the blower motors.
EEM Motors
NOTE: Refer to the wiring diagram in the appendix to verify speed tap settings.
A/GPU3 models are equipped with EEM motors. EEM motors are constant torque motors with very low power consumption. This motor is energized by 24V. Adjust the
CFM for the unit by changing the 24V low voltage leads to the speed terminal block on the motor.

Limit Check
Check limit control operation after 15 minutes of operation by blocking the return air grille(s).

1. After several minutes the main burners must go OFF. Blower will continue to run.
2. Remove air restrictions and main burners will relight after a cool down period of a few minutes.

Adjust the thermostat setting below room temperature.

1. Main burners must go OFF.
2. Circulating Air Blower will continue to run for 90, 120, 150 or 180 seconds, depending on the setting.

NOTE: If necessary, adjust fan OFF delay settings to obtain satisfactory comfort level.
WARNING
This unit must be used as a “construction heater” during the finishing phases of construction on a new structure. This type of use may result in premature failure of the unit die to extremely low return air temperatures and exposure to corrosive or very dirty atmosphere.
Unit Shutdown

1. Set the thermostat to lowest setting.
2. Turn off the electrical power supply to the unit.
3. Remove the heat exchanger door on the side of the unit by removing screws.
4. Move the gas control valve switch to the OFF position. Do not force.
5. Close manual gas shutoff valve external to the unit.
6.  Replace the heat exchanger door on the unit.
7. If cooling and/or air circulation will be desired, turn ON the electrical power.

Cooling Startup
NOTE: The outdoor temperature must be 60°F or higher before making adjustments to charge.
NOTE: Check all manual reset limit controls in heating circuit if cooling mode does not operate.
Compressor Protection Devices
The compressor includes components which are designed to protect the compressor against abnormal operating conditions.
WARNING
To prevent personal injury or death, always disconnect electrical power before inspecting or servicing the unit. NOTE: All compressor protection devices reset automatically, energizing the contactor and outdoor fan.
WARNING
Do not bypass safety devices.
Refrigerant Charge Check
After completing airflow measurements and adjustments the unit’s refrigerant charge must be checked. The unit comes factory charged, but this charge is based on 325 CFM per ton and minimum ESP per AHRI test conditions (generally between .15-.28 ESP). When air quantity or ESP is different than above, the refrigerant charge must be adjusted to the proper amount. All package units with fixed orifice devices are charged using the super heat method at the compressor suction line.
After superheat is adjusted it is recommended to check unit sub-cooling at the condenser coil liquid line out. For charge adjustments, see superheat and sub- cooling charts show for each model.
Checking Subcooling
NOTE: Units with a TXV should be charged to Subcooling only.
SUBCOOLING FORMULA = SATURATED LIQUID LINE TEMPERATURE – LIQUID LINE TEMPERATURE
EXAMPLE:
a. Liquid Line Pressure = 417 PSI
b. Corresponding Temp. = 120°F
c. Thermometer on Liquid line = 109°F.
To obtain the amount of subcooling, subtract 109°F from 120°F. The difference is 11° subcooling. See the specification sheet or technical information manual for the
design subcooling range for your unit.
SUBCOOLING FORMULA = SATURATED LIQUID LINE TEMPERATURE – LIQUID LINE TEMPERATURE
Checking Superheat
EXAMPLE:
a. Suction Pressure = 143 PSI
b. Corresponding Temp. = 50°F
c. Thermometer on Suction Line = 59°F
To obtain the degrees temperature of superheat, subtract 50.0 from 59.0°F. The difference is 9° Superheat. The 9° Superheat would fall in the ± range of allowable superheat.
SUPERHEAT = SUCTION LINE TEMP – SAT. SUCTION TEMP.
Superheat Adjustment
NOTE: Superheat adjustments should not be made until indoor ambient conditions have stabilized. This could take up to 24 hours depending on indoor temperature and humidity. Before checking superheat run the unit in cooling for 10-15 minutes or until refrigerant pressures stabilize. Use the fol¬lowing guidelines and methods to check unit
operation and ensure that the refrigerant charge is within limits.
For TXV systems, to adjust superheat, unscrew the cover from the expansion valve, locate the adjustment screw, and turn it clockwise (in) to increase superheat or  counterclockwise (out) to decrease superheat. It is recommended to make small adjustments at a time, 1/8-1/4 turn increments. Replace adjustment cap. Wait a minimum
of 10 minutes between adjustments to allow time for the TXV and pressures to stabilize.
Refrigerant Charge Check
NOTE: For optimal performance, follow charging instructions below.
(Units with Fixed Orifice Devices)
All package units with fixed orifice devices are charged using the superheat method at the compressor suction line. To increase super heat, remove charge and to decrease
super heat, add charge. After superheat is adjusted, it is recommended to check unit subcooling at the condenser coil liquid line. See Design Superheat and Subcooling table
for targets on each model.
(Units with Expansion valve (TXV))
Single Stage Cooling Application: Refer to the Design Superheat & Subcooling table.
Two-Stage Cooling Application: Run unit on Low Stage cooling and refer to Design Superheat & Subcooling table.

1. Purge gauge lines. Connect service gauge manifold to access fittings. Run system at least 10 minuets to allow pressure to stabilize.

2. Temporarily install thermometer on liquid (small) line near liquid line access fitting with adequate contact and insulate for best possible reading.

3. Check subcooling and superheat. System should have a subcooling and superheat within the range listed on the Design Superheat and Subcooling table.
   a. If subcooling and superheat are low, adjust TXV superheat, then check subcooling.
   NOTE: To adjust superheat, turn the valve stem clockwise to increase and counterclockwise to decrease.
   b. If subcooling is low and superheat is high, add charge to raise subcooling then check superheat.
   c. If subcooling and superheat are high, adjust TXV valve superheat, then check subcooling.
   d. If subcooling is high and superheat is low, adjust TXV valve superheat and remove charge to lower the subcooling.
   NOTE: Do NOT adjust the charge based on suction pressure unless there is a gross undercharge.

4. Disconnect manifold set, installation is complete.

3. Set the room thermostat to the desired temperature.

TROUBLESHOOTING

Ignition Control Error Codes
The following presents probable causes of questionable unit operation. Refer to Diagnostic Indicator Chart for an interpretation of the signal and to this section for an
explanation.
Remove the control box access panel and note the number of diagnostic LED flashes. Refer to Diagnostic Indicator Chart for an interpretation of the signal and to this section for an explanation.
Fault Recall
The ignition control is equipped with a momentary pushbutton switch that can be used to display on the diagnostic LED the last five faults detected by the control. Any time the control is powered, the fault code history can be retrieved for display by depressing and releasing the button once (less than 5 seconds); the LED will flash the Fault Code History (up to 5 fault codes from newest to oldest). The Fault Code History is retained between power cycles until cleared. A fault code is added to the history log as it is encountered if it differs from the most recent history log item. If the history log is already full, then the oldest entry is dropped from the log and the remaining entries are moved down in the Fault Code History so that the new fault can be added to the Fault Code History as the most recent fault.
NOTE: Do not hold for longer than 5 seconds. Holding the button for 5 seconds or higher will erase the memory!

Resetting From Lockout
An external lockout occurs if the integrated ignition control determines that a measurable combustion cannot be established within three (3) consecutive ignition attempts. If flame is not established within the four (4) second trial for ignition, the gas valve is de-energized, 30 second interpurge cycle is completed, and ignition is re-attempted. The control will repeat this routine three times if a measurable combustion is not established. The control will then shut off the induced draft blower and go into a lockout state. If flame is established but lost, the control will energize the circulator blower at the heat speed and then begin a new ignition sequence. If flame is established then lost on subsequent attempts, the control will recycle the ignition sequence.
The diagnostic fault code is 1 flash for a lockout due to failed ignition attempts. The integrated control will automatically reset after one hour, or it can be reset by removing the thermostat signal or disconnecting the electrical power supply for over five seconds.
IMPORTANT NOTE: If you have to frequently reset your gas/electric package unit, it means that a problem exists that should be corrected. Contact a qualified servicer for further information.
Pressure Sensor
The pressure sensor is mounted near induced draft blower. Its function is to regulate the induced draft blower’s speed in order to maintain proper air-fuel ratio for clean and reliable combustion. The electrical output signal from the sensor is expected to be proportional to the magnitude of the differential pressure between the inducer inlet negative pressure and the ambient air pressure. The pressure sensor also guards against insufficient airflow (combustion air and flue products) through the heat exchanger. At the beginning of a call for heat, the control ensures the inducer is in an off state, then checks the pressure sensor output for the proper null offset value. If the pressure sensor output is outside the acceptable range for the null value, the control enters a five minute lockout. After the lockout timer has expired, the control resumes normal operation.
During inducer operation, including all operating modes except for the null test, the control monitors the pressure sensor output for expected values. The control limits
during normal operation are expected to be within certain tolerances of the target pressures. In response to a pressure sensor span error, the control enters a five minute
lockout. After the lockout timer has expired, the control resumes normal operation.
Primary Limit
A primary limit will open due to excessive supply air temperatures. This can be caused by a dirty filter, excessive duct static, insufficient air flow, or a faulty limit. Check filters, total external duct static, blower motor, blower motor speed tap (see wiring diagram), and limit. This limit will automatically reset once the temperature falls below a preset level.
If a limit switch opens, the gas valve is immediately deenergized, the induced draft and air circulating blowers are energized. The induced draft and air circulator blowers remain energized for 5 minutes or until the limit switch recloses, whichever happens first.
NOTE: If the primary limit opens three (3) times within the same call for heat, the ignition control will lock out for one (1) hour with the air circulating blower energized at high heat speed.
Flame Detected with Gas Valve Closed
If flame is detected with the gas valve de-energized, the combustion and air circulator blowers are energized. The control can be reset by removing the power supply to the unit or it will automatically reset after one hour. Miswiring is the probable cause for this fault. The initial lockout period is 5 minutes. After that time, the control continues to monitor the flame sense input and resumes normal operation when flame is no longer sensed.
Low Flame Signal
Under some conditions, the fuel or air supply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator causing a drop in the flame signal. If
the flame signal drops below a predetermined value, the ignition control will display an error code of (1) flash on the amber diagnostic LED. The unit will continue to operate
until the control can no longer detect flame.
Burner Temperature Switch
The burner temperature switch is mounted on the burner box assembly to monitor the burner box temperature. It is normally closed (electrically), auto-reset switch. This switch guards against the burner flames not being properly drawn into the heat exchanger.
The control senses an open blocked burner switch, indicating that the burner temperature/pressure has exceeded its set point. The control de-energizes the gas valve, energizes the inducer to the pre-purge setting and energizes the indoor blower. The initial lockout period is five minutes. After this time elapses, the control evaluates the
state of the blocked burner switch. If the switch is closed, the control resumes normal operation. The control will enter a one hour lockout state if the blocked burner switch fails to reset before the recovery timer has expired.
ID Plug
The control operational parameters are stored in ID Plug which connects on the circuit board. The control requires a valid ID plug present to operate in heating mode. If a valid ID plug is not present the control will not respond to a call for heat. However, the control will respond to thermostat inputs “Y” or “G”, operating the appropriate fan output. The cooling delays are ignored in this operating mode. The control puts the burner into hard lockout and will not respond to heating requests until the power is cycled with a valid ID plug installed.
Abnormal Operation – Cooling
Short Cycle Compressor Delay
In the event of intermittent power losses or intermittent thermostat operation, the control system will delay output to the compressor contactor for three minutes from the time power is restored or thermostat call for cooling is restored. (Compressor is off a total of three minutes).
NOTE: Some electronic thermostats also have a built-in compressor short cycle timer that may be longer than the three minute delay given above. If you are using an electronic thermostat and the
compressor has not started after three minutes, wait an additional five minutes to allow the thermostat to complete its short cycle delay time.
High Pressure Switch/Low Pressure Switch
Some models include a high pressure cutout switch and/ or a low pressure switch. The high pressure cutout switch protects the refrigeration system from excessive operating
pressures. The low pressure switch protects the refrigeration system from very low operating pressures due to a loss of refrigerant. Compressor operation will be disabled if either of these devices opens.

MAINTENANCE

WARNING
HIGH VOLTAGE
Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.
Have the gas heating section of the unit checked at least once a year before the heating season begins, to be sure that the combustion air inlet and flue outlet hoods are not blocked by debris, which would prevent adequate combustion air and a properly operating vent system.
Filter Replacement or Cleaning
A return air filter is not supplied with this unit; however, there must be a means of filtering all of the return air. The filter(s) may be located in the return air duct(s), or return air filter grille(s). Consult with your installing dealer for the actual location of the return air filter(s) for your unit. Dirty filters are the most common cause of inadequate heating or cooling performance. Filter inspection should be made at least every two months; more often if necessary because of local conditions and usage.
Dirty throwaway filters should be discarded and replaced with a new, clean filter. Dirty permanent filters should be washed with water, thoroughly dried and sprayed with a filter adhesive before being reinstalled (Filter adhesives may be found at many hardware stores). Permanent filters should last several years. However, should one become torn or uncleanable, it should be replaced.
Cabinet Finish Maintenance
Use a fine grade automotive wax on the cabinet finish to maintain the finish’s original high luster. This is especially important in installations with extended periods of direct
sunlight.
Clean Outside Coil (Qualified Servicer Only)
The coil with the outside air flowing over it should be inspected annually and cleaned as frequently as necessary to keep the finned areas free of lint, hair and debris. Condenser, Evaporator, and Induced Draft Motors Bearings on the air circulating blower motor, condenser motor and the combustion fan motor are permanently lubricated. No additional oiling is required.
Flame Sensor (Qualified Servicer Only)
A drop in the flame current can be caused by a nearly invisible coating on the flame sensor. This coating, created by the fuel or combustion air supply, can be removed by carefully cleaning the flame sensor with steel wool.
NOTE: After cleaning, the microamp signal should be stable and in the range of 5-10 microamps DC.
Flue Passages (Qualified Servicer Only)
At the start of each heating season, inspect and, if necessary, clean the unit flue passage.
Cleaning Flue Passages (Qualified Servicer Only)

1. Shut off electric power and gas supply to the unit.
2. Remove burner assembly by disconnecting the gas line and removing the manifold bracket from the partition panel.
3. Remove the flue from the induced draft blower and the collector box cover from the partition panel.
4. The primary heat exchanger tubes can be cleaned using a round wire brush attached to a length of high grade stainless steel cable, such as drain cleanout cable. Attach a variable speed reversible drill to the other end of the spring cable. Slowly rotate the cable with the drill and insert it into one of the primary heat exchanger tubes. While reversing the drill, work the cable in and out several times to obtain sufficient cleaning. Use a large cable for the large tube, and then repeat the operation with a small cable for the smaller tube. Repeat for each tube.
5. When all heat exchanger tubes have been cleaned, replace the parts in the reverse order in which they were removed.
6. To reduce the chances of repeated fouling of the heat exchanger, perform the steps listed in “Startup, Adjustments, and Checks”.

Burners

WARNING
To avoid personal injury or death due to electric shock, do not remove any internal compartment covers or attempt any adjustment. Contact a qualified servicer at once if an
abnormal flame should develop.
The Ultra low NOx models are equipped with premix burner. The burner box is sealed to achieve safe and reliable operation. The burner box should not have any blockage near the air-gas mixer inlet.
CAUTION
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
CAUTION
Always verify proper operation after servicing.
For further information on the yearly inspection, consult the User Manual. It is recommended that a qualified servicer inspect and service the unit at least once each year. Turn the unit on at the thermostat. Wait a few minutes, since any dislodged dust will alter the normal flame appearance. Flames should be predominantly blue and directed into the tubes. They should not be yellow. They should extend directly outward from the burner ports without curling downward, floating or lifting off the ports.

HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
PA C K A G E U N I T S – D u a l F u e l & G a s
HOMEOWNER’S Routine Maintenance Recommendations
We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin
WARNING
HIGH VOLTAGE
Disconnect all power before servicing or installing this unit. Failure to do so may cause property damage, personal injury or death.
Replace or Clean Filter
IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
A return air filter is not supplied with this unit; however, there must be a means of filtering the return air. An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your comfort system clean. A dirty coil could cause poor operation and/or severe equipment damage.
The installer of your unit can tell you where your filter(s) are and how to clean or replace them.
Check your return filter(s) at least once every two months. When they are dirty, replace or clean as required Disposable type filters should be replaced. Reusable type
filters may be cleaned.
NOTE: Reusable type filters should be washed with warm water, dried completely and sprayed with an adhesive according to the manufacturers recommendations.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types. These filters can do a better job
of catching small airborne particles.
Improper filter maintenance is the most common cause of inadequate heating or cooling performance. Filters should be cleaned (permanent) or replaced (disposable) every two months or as required. When replacing a filter, it must be replaced with a filter of the same type and size and always make certain the air flow arrows on the filter point in the proper direction.

• Check the thermostat to confirm that it is properly set.
• Check the disconnect switch near the unit to confirm that it is closed.
• Check the electrical panel for tripped circuit breakers or failed fuses. Reset the circuit breakers or replace fuses as necessary.
• Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked

Condenser, Evaporator and Induced Draft Motors
The bearings on the air circulating blower motor, condenser motor and the combustion fan motor are permanently lubricated and require no further lubrication.
Compressor
The compressor motor is hermetically sealed and does not require additional oiling.
Annual Inspection (Qualified Servicer Only)
Your package unit should be inspected by a qualified installer, or service agency at least twice every year. This check should be performed before the heating and cooling seasons begin. This will ensure that adequate combustion air is being drawn and the vent system is working properly. Particular attention should be paid to the following items. Repair as necessary.

• Check physical support of the unit. Ensure it is sound without any sagging, cracks, or gaps, around the base.
• Check for obvious signs of deterioration of the unit.
• Flue Hood and Combustion Air Inlet. Check for blockage (wasp nest, etc.) and corrosion.
• Flue Hood (Qualified Servicer Only)
• Return Air Connection. Check for physical soundness and ensure that the connection is firmly sealed to the package unit casing.
• Heat exchanger. Check for corrosion and/or obstructions within the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame, and flame sense.
• Wiring. Check wires for damage. Check electrical connections for tightness and/or corrosion.
• Filters. Check that filters are clean and in the proper placement in the unit or duct system.
• Louvers. Inspect air inlet louvers inside the heat exchanger compartments. Ensure the area is clean and free of dirt and debris.

Clean Outside Coil (Qualified Servicer Only)
The outdoor coil should be inspected annually. It is important to keep the outdoor coil clean. Dirt, leaves, or debris could restrict the airflow. If cleaning of the outdoor coil becomes necessary, hire a qualified servicer. Inexperienced people could easily puncture the tubing in the coil.  by objects (rugs, curtains or furniture).

Before Calling Your Servicer

• Check for obstructions on the unit. Confirm that it has not been covered on the sides or the top. Remove any obstruction that can be safely removed. If the unit is
  covered with dirt or debris, call a qualified servicer to clean it.

• Check the filter. If it is dirty, clean or replace it.
