To avoid possible illness or death of the building occupants,  
do NOT locate outside air intake device (economizer,  
manual fresh air intake, motorized fresh air intake) too close  
to an exhaust outlet, gas vent termination, or plumbing vent  
outlet. For specific distances required, consult local codes.  
•
•
Allow minimum clearances from the enclosure for fire  
protection, proper operation, and service access (see  
appendix). These clearances must be permanently  
maintained.  
The combustion air inlet and flue outlet hoods on the unit  
must never be obstructed. If used, do not allow the  
economizer/manual fresh air damper/ motorized fresh air  
damper to become blocked by snow or debris. In some  
climates or locations, it may be necessary to elevate the  
unit to avoid these problems.  
CARBON MONOXIDE POISONING HAZARD  
Special Warning for Installation of Furnaces or Air Handling Units in  
Enclosed Areas such as Garages, Utility Rooms or Parking Areas  
Carbon monoxide producing devices (such as an automobile, space  
heater, gas water heater, etc.) should not be operated in enclosed areas  
such as unventilated garages, utility rooms or parking areas because of  
the danger of carbon monoxide (CO) poisoning resulting from the exhaust  
emissions. If a furnace or air handler is installed in an enclosed area such  
as a garage, utility room or parking area and a carbon monoxide producing  
device is operated therein, there must be adequate, direct outside  
ventilation.  
•
When the unit is heating, the temperature of the return air  
entering the unit must be between 50° F and 100° F.  
GROUND LEVEL INSTALLATIONS ONLY:  
•
When the unit is installed on the ground adjacent to the  
building, a level concrete (or equal) base is recommended.  
Prepare a base that is 3” larger than the package unit  
footprint and a minimum of 3” thick.  
This ventilation is necessary to avoid the danger of CO poisoning which  
can occur if a carbon monoxide producing device continues to operate in  
the enclosed area. Carbon monoxide emissions can be (re)circulated  
throughout the structure if the furnace or air handler is operating in any  
mode.  
•
The base should also be located where no runoff of water  
from higher ground can collect in the unit.  
CO can cause serious illness including permanent brain damage or death.

•
Listed gas appliance connectors used in accordance with  
the terms of their listing that are completely in the same  
room as the equipment  
In the prior two methods above the connector or tubing  
must be protected from physical and thermal damage.  
Aluminum alloy tubing and connectors must be coated to  
protect against external corrosion when in contact with  
masonry, plaster or insulation or are subject to repeated  
wettings by liquids (water - not rain water, detergents or  
sewage)  
, BE SURE THERE IS  
TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY  
NO OPEN FLAME IN THE VICINITY DURING AIR BLEEDING.  
There will be air in the gas supply line after testing for leaks  
on a new installation. Therefore, the air must be bled from the  
line by loosening the ground joint union until pure gas is  
expelled. Tighten union and wait for five minutes until all gas  
has been dissipated in the air. Be certain there is no open  
flame in the vicinity during air bleeding procedure. The unit is

TANKS AND PIPING  
WARNING  
Complete information regarding tank sizing for vaporization,  
recommended regulator settings and pipe sizing is available  
from most regulator manufacturers and propane gas suppliers.  
Since propane gas will quickly dissolve white lead or most  
standard commercial compounds, special pipe dope must be  
used. Shellac base compounds resistant to the actions of  
liquefied petroleum gases such as Gasolac®, Stalactic®,  
Clyde’s® or John Crane® are satisfactory.  
TO PREVENT PROPERTY DAMAGE OR SERIOUS PERSONAL INJURY DUE TO  
FIRE OR EXPLOSION CAUSED BY A PROPANE GAS LEAK, INSTALL A GAS  
DETECTING WARNING DEVICE.  
IF THE PROPANE GAS UNIT IS INSTALLED IN AN EXCAVATED AREA OR A  
CONFINED SPACE, A WARNING DEVICE IS REQUIRED DUE TO:  
• PROPANE GAS IS HEAVIER THAN AIR AND ANY LEAKING GAS CAN  
SETTLE IN ANY LOW AREAS OR CONFINED SPACES.  
• PROPANE GAS ODORANT MAY FADE, MAKING THE GAS UNDETECTABLE  
EXCEPT WITH A WARNING DEVICE.

*PG1360***1A Only  
A duct system should be installed in accordance with  
Standards of the National Board of Fire Underwriters for the  
Installation of Air Conditioning, Warm Air Heating and  
Ventilating Systems. Pamphlets No. 90A and 90B.  
The supply duct from the unit through a wall may be installed  
without clearance. However, minimum unit clearances as  
shown in the appendix must be maintained. The supply duct  
should be provided with an access panel large enough to  
inspect the air chamber downstream of the heat exchanger. A  
cover should be tightly attached to prevent air leaks.  
CIRCULATING AIR AND FILTERS  
AIRFLOW CONVERSION  
Units can easily be converted from horizontal to down-  
discharge airflow delivery. In down-discharge or high static  
installations, the installer should measure the total external  
static and review the blower performance charts before  
performing the installation. In some installations it will be  
necessary to change the blower speed to provide proper air  
flow.  
For duct flange dimensions on the unit refer to the Unit  
Dimension illustration in the appendix.  
Horizontal Air Flow (Applies to 3 phase models)  
For down-discharge applications, the ductwork should be  
attached to the roof curb prior to installing the unit. Ductwork  
dimensions are shown in the roof curb installation manual.  
Single phase models are shipped without horizontal duct  
covers. If needed, these kits may be ordered through  
Goodman’s Service Parts department.  
Remove supply and return duct covers which are attached to  
the unit as shown below.  
If desired, supply and return duct connections to the unit may  
be made with flexible connections to reduce possible unit  
operating sound transmission.

SecondaryLimitControl  
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.

Manifold Pressure Check  
The gas valve has a tapped opening to facilitate measurement  
of the manifold pressure.A“U” Tube manometer having a scale  
range from 0 to 12 inches of water should be used for this  
measurement. The manifold pressure must be measured with  
the burners operating.

White-Rodgers 36G22  
To adjust the pressure regulator, remove the adjustment screw  
or cover on the gas valve. Turn out (counterclockwise) to  
decrease pressure, turn in (clockwise) to increase pressure.  
Only small variations in gas flow should be made by means  
of the pressure regulator adjustment. In no case should the  
final manifold pressure vary more than plus or minus 0.3  
inches water column from the specified nominal pressure.  
Any major changes in flow should be made by changing the  
size of the burner orifices. The measured input rate to the  
furnace must not exceed the rating specified on the unit rating  
plate.  
GasSupplyAndManifoldCheck  
Gas supply pressure and manifold pressure with the burners  
operating must be as specified on the rating plate.  
Gas Inlet Pressure Check  
Gas inlet pressure must be checked and adjusted in  
accordance to the type of fuel being consumed.  
With Power And Gas Off:  
1. Connect a water manometer or adequate gauge to the inlet  
pressure tap of the gas valve.  
For natural gas, the manifold pressure must be between 3.2  
and 3.8 inches water column (3.5 nominal).  
For propane gas, the manifold pressure must be between 9.7  
and 10.3 inches water column (10.0 nominal).  
Inlet gas pressure can also be measured by removing the  
cap from the dripleg and installing a predrilled cap with a  
hose fitting.  
Gas Input (Natural Gas Only) Check  
With Power And Gas On:  
To measure the gas input use a gas meter and proceed as  
follows:  
2. Put unit into heating cycle and turn on all other gas  
consuming appliances.  
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 34 seconds per cubic foot as determined by Step 2, then:  
Input = 1000 x 3600 / 34 = 106,000 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.

Main Burner Flame Check  
(switches 1 and 2) provides airflow adjustment for heating  
airflow. The “COOL” adjustment function (switches 5 and 6)  
provides airflow adjustments for cooling airflow. The  
“ADJUST” function (switches 7 and 8) will adjust the heating  
AND cooling airflow +10% or - 15%. The “DELAY” function  
(switches 3 and 4) is not field adjustable.  
Flames should be stable, soft and blue (dust may cause  
orange tips but they must not be yellow) and extending directly  
outward from the burner without curling, floating or lifting off.  
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.  
O
N
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.  
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. Ahigher 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 tempera-  
ture rise through the unit as marked on the rating plate.  
To adjust the HEAT, COOL or ADJUST functions, simply change  
the ON/OFF position of the appropriate dipswitches. The table  
below shows the ON/OFF combinations for the various switches  
and the corresponding A, B, C, or D taps. Refer to the Product  
Data Book applicable to your model for airflow tables and  
temperature rise. The “Dipswitch Position” table below shows  
the factory dipswitch settings for each model. The “CFM” table

*PG1360***1A ONLY: Low stage airflow is approximately 75%  
of high stage cooling airflow. Example: High stage cooling  
airflow is 1800 CFM. Low stage cooling airflow is 0.75*1800  
CFM = 1350 CFM.  
The adjustment factors for the ADJUST function are A = 1, B =  
1.10 (+10%) and C = 0.85 (-15%). The D tap for the ADJUST  
function has no effect on airflow. Example: Airflow tables  
indicate 1425 CFM. With the ADJUST set to B tap, the CFM  
becomes 1.10*1425 CFM = 1568 CFM.  
*PG13(48, 60)***1A models are equipped with GE ECM  
motors. These motors offer greater airflow flexibility as well  
as dehumidification. The airflow delivery for these models  
can be adjusted by changing the position of dip switches on  
a low voltage terminal board. The figure below shows the  
dipswitch layout on the low voltage terminal board as well as  
the function of each set of switches. The “HEAT” function

Dehumidification  
COOLING STARTUP  
The GE ECM motor has the capability to provide increased  
dehumidification during cooling operation. This is  
accomplished by lowering the airflow to approximately 85%  
of the nominal cooling airflow. Example: Unit is operating at  
1400 CFM and humidistat calls for dehumidification. Resulting  
airflow is 0.85* 1400 CFM = 1190 CFM.  
To make use of this feature, a 24VAC humidistat which  
opens on humidity rise is required. Connect humidistat to  
the HUMIDISTAT/HUM terminal on the low voltage terminal  
board (see wiring diagram in the appendix). Clip the HUM/  
PJ6 jumper on the low voltage terminal board. The system  
is now ready to provide dehumidification.  
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  
O PREVENT PERSONAL INJURY OR DEATH, ALWAYS DISCONNECT ELECTRICAL  
T
POWER BEFORE INSPECTING OR SERVICING THE UNIT. ALL COMPRESSOR  
PROTECTION DEVICES RESET AUTOMATICALLY, ENERGIZING THE CONTACTOR  
AND OUTDOOR FAN.  
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.  
CoolingRefrigerantCharging  
Check unit charge before putting the cooling section into full  
operation. The unit is factory charged with R-22 for nominal air  
flow and static pressure conditions. The unit has a piston  
flowrator expansion device.  
Adjust the thermostat setting below room temperature.  
1. Main burners must go OFF.  
2. Circulating Air Blower will continue to run for 120, 135 or  
150 seconds, depending on the setting.  
*PG13(48,60)***1A ONLY: Circulating Air Blower will  
continue to run for 180 seconds.  
NOTE: *PG1360 is equipped with a thermostatic valve expansion  
device.  
To ensure the unit is properly charged for the intended  
application, check the unit refrigerant superheat at the  
compressor. The refrigerant superheat is a function of outdoor  
ambient temperature and return air temperature of the  
conditioned space. It is the installing contractors responsibility  
to ensure the proper refrigerant superheat at the compressor  
is adjusted for each application. For example, 10 degree  
refrigerant superheat level is adequate for a 95 degree outdoor  
ambient temperature and a 78 - 80 degree for indoor return air  
temperature. As the outdoor ambient temperature rises the  
superheat decreases and as the outdoor ambient temperature  
lowers the superheat increases. Proper superheat adjustment  
optimizes cooling performance.

Pressure Switch Stuck Open  
ABNORMAL OPERATION - HEATING  
A pressure switch stuck open can be caused by a faulty  
pressure switch, faulty wiring, a disconnected or damaged  
hose, a blocked or restricted flue, or a faulty induced draft  
blower.  
If the control senses an open pressure switch during the pre-  
purge cycle, the induced draft blower only will be energized. If  
the pressure switch opens after ignition has begun the gas  
valve is deenergized, the circulator blower heat off cycle begins,  
and the induced draft blower remains on. The diagnostic fault  
code is two flashes.  
InternalControlFailure  
If the integrated ignition control in this unit encounters an  
internal fault, it will go into a “hard” lockout and turn off the  
diagnostic LED. If diagnostic LED indicates an internal fault,  
check power supply to unit for proper voltage, check all fuses,  
circuit breakers and wiring. Disconnect electric power for five  
seconds. If LED remains off after restoring power, replace  
control.  
External Lockout  
Pressure Switch Stuck Closed  
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 seven (7) second trial for  
ignition, the gas valve is deenergized, 15 second inter-purge  
cycle is completed, and ignition is reattempted. 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 for four (4) consecutive  
ignition attempts (five attempts total) before locking out.  
The diagnostic fault code is 1 flash for a lockout due to failed  
ignition attempts or flame dropouts. 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. If the diagnostic LED  
indicates an external lockout, perform the following checks:  
A stuck closed pressure switch can be caused by a faulty  
pressure switch or faulty wiring. If the control encounters a  
pressure switch stuck closed, the induced draft blower remains  
off. The diagnostic LED code for this fault is three (3) flashes.  
Open Thermal Protection Device  
If the primary 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 until the limit switch recloses. The diagnostic fault  
code for an open limit is four (4) flashes.  
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.  
Flame Detected with Gas Valve Closed  
If flame is detected with the gas valve deenergized, the  
combustion and air circulator blowers are energized. The  
diagnostic fault code is five (5) flashes for this condition. 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.

Check the supply and manifold pressures  
Check the gas orifices for debris  
Check gas valve for proper operation  
Check secondary limit  
A dirty filter, excessive duct static, insufficient air flow, a  
faulty limit, or a failed circulator blower can cause this  
limit to open. Check filters, total external duct static,  
circulator blower motor, blower motor speed tap (see  
wiring diagram), and limit. An interruption in electrical  
power during a heating cycle may also cause the  
auxiliary limit to open. The automatic reset secondary  
limit is located on top of the circulator blower assembly.  
Check rollout limit  
ABNORMAL OPERATION - COOLING  
Short Cycle Compressor Delay  
The automatic ignition control has a built-in feature that  
prevents damage to the compressor in short cycling  
situations. In the event of intermittent power losses or  
intermittent thermostat operation, the ignition control will delay  
output to the compressor contactor for three minutes from the  
time power is restored. (Compressor is off a total of three  
minutes). The diagnostic LED will flash six (6) times to indicate  
the compressor contactor output is being delayed.  
•
If the burner flames are not properly drawn into the heat  
exchanger, the flame rollout protection device will open.  
Possible causes are restricted or blocked flue passages,  
blocked or cracked heat exchanger, a failed induced  
draft blower, or insufficient combustion air. The rollout  
protection device is a manual reset limit located on the  
burner bracket. The cause of the flame rollout must be  
determined and corrected before resetting the limit.  
Check flame sensor  
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.

•
A drop in flame signal can be caused by nearly invisible  
coating on the sensor. Remove the sensor and carefully  
clean with steel wool.  
Check wiring  
Check wiring for opens/shorts and miswiring.  
Important: 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.

MAINTENANCE  
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.  
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.  
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.  
FILTER REPLACEMENT OR CLEANING  
NOTE: After cleaning, the microamp signal should be stable and in  
the range of 4 - 6 microamps DC.  
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.  
Flame  
Sensor  
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.  
Flame Sensor  
CABINET FINISH MAINTENANCE  
FLUE PASSAGES (QUALIFIED SERVICER ONLY)  
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.  
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”.
