CARBON MONOXIDE POISONING HAZARD

Special Warning for Installation of Furnaces or Air Handling U n its 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) pois oning resulting from the exh aust
emissions. If a furnace or a ir handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is oper ated therein, there mus t be adequate, direct outsi de
ventilation.

This ventilation is necessary to avoid t he danger of CO poisoning whi ch
can occur if a carbon monoxide producing device continues to operate in
the enclose d area. Carbon monoxide emi ssions can be (re)circulated
throughout t he structure if the furnace or air handler is operating i n any
mode.

CO can cause ser ious illness including permanent brain damage or death.

B10259-216

• T o avoid possible illness or death of the building occup ants,

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.

• When the unit is heating, the temperature of the return air

entering the unit must be between 50° F and 100° F.

IMPORTANT NOTE: Propane gas conversion kits must be

installed to convert units to propane gas.
All propane gas equipment must conform to the safety

standards of the National Board of Fire Underwriters (See NBFU
Manual 58).

For satisfactory operation, propane gas supply pressure must
be within 9.7 - 10.3 inches W.C. at the manifold with all gas
appliances in operation. Maintaining proper gas pressure
depends on three main factors:

1. V aporization rate, which depends on (a) temperature of the
liquid, and (b) wetted surface area of the container or
containers.

2. Proper pressure regulation.

3. Pressure drop in lines between regulators, and between
second stage regulator and the appliance. Pipe size
required will depend on length of pipe run and total load of
all appliances.

CIRCULATING AIR AND FILTERS

AIRFLOW CONVERSION

Units can easily be converted from horizontal to down­discharge 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.

Horizontal Air Flow (Applies to 3 phase models)

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.

Down Discharge Applications

Cut insulation around bottom openings and remove panels
from the bottom of the unit, saving the screws holding the
panels in place.

NOTE: Single phase models require installation of horizontal
duct kit #20464501PDGK (medium chassis) and
#20464502PDGK (large chassis).

DUCTWORK

Duct systems and register sizes must be properly designed
for the C.F.M. and external static pressure rating of the unit.
Ductwork should be designed in accordance with the
recommended methods of Air Conditioning Contractors of
America Manual D (Residential) or Manual Q (Commercial).
All ductwork exposed to the outdoors must include a
weatherproof barrier and adequate insulation.

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.

For duct flange dimensions on the unit refer to the Unit
Dimension illustration in the appendix.

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.

If desired, supply and return duct connections to the unit may
be made with flexible connections to reduce possible unit
operating sound transmission.

Remove these covers

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 recheck for wiring errors, or
obstructions in or near the blower motors. Duct covers must

be removed before operating unit.

Heat Anticipator Setting

Set the heat anticipator on the room thermostat to 0.4 amps to
obtain the proper number of heating cycles per hour and to
prevent the room temperature from overshooting the room
thermostat setting.

Rollout Protection Control

The rollout protection device opens, cutting power to the gas
valve, if the flames from the burners are not properly drawn
into the heat exchanger. The rollout protection device is located
on the burner bracket. The reason for elevated temperatures
at the control should be determined and repaired prior to
resetting this manual reset control.

WARNING

O AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE

T

OR EXPLOSION, A QUALIFIED SERVICER MUST INVESTIGATE THE REASON FOR
THE ROLLOUT PROTECTION DEVICE TO OPEN BEFORE MANUALLY RESETTING
THE ROLLOUT PROTECTION DEVICE.

Rollout Protection

Rollout Protection on Burner Bracket

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.

Gas Supply And Manifold Check

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.
Inlet gas pressure can also be measured by removing the
cap from the dripleg and installing a predrilled cap with a
hose fitting.

With Power And Gas On:

2. Put unit into heating cycle and turn on all other gas
consuming appliances.

Inlet Gas Pressure

Natural Min. 5.0" W.C., Max. 10.0" W.C.

Propane Min. 11.0" W.C., Max. 13.0" W.C.

NOTE: Inlet Gas Pressure Must Not Exceed the Maximum Value
Shown.

If operating pressures differ from above, make necessary
pressure regulator adjustments, check piping size, etc., and/
or consult with local utility.

Manometer

Measuring Inlet Gas Pressure

Alternate Method

Manifold Pressure Check

The gas valve has a tapped opening to facilitate measurement
of the manifold pressure. A “U” T ube 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.

T o 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.

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).

Gas 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 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.

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

13

Main Burner Flame Check

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.

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. 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.

Blower Speed Adjustments

WARNING

O AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK, REMOVE

T

ELECTRICAL POWER FROM THE UNIT BEFORE CHANGING SPEED TAPS ON THE
BLOWER MOTOR.

Refer to the wiring diagram in the appendix to verify speed tap
settings.

Blower speeds are to be changed at the ignition control board.
Both heat speed and cool speed terminals are supplied on
the board along with two unused motor lead terminals.

*PG13(48, 60)***1B, 3A, 4A models are equipped with X-13
motors. X-13 motors are constant torque motors with very low
power consumption. This motor is energized by 24V. Adjust

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.

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 120, 135 or
150 seconds, depending on the setting.

*PG13(48,60)***1A ONLY: Circulating Air Blower will

continue to run for 180 seconds.

COOLING STARTUP

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 S ERVICING T HE UNIT.
PROTECTION DEVICES RESET AUTOMATICALLY, ENERGIZING THE CONTACTOR
AND OUTDOOR FAN.

Cooling Refrigerant Charging

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.

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.

For models equipped with thermostatic expansion valve, charge
system to 12-14 degrees of subcooling, adjust expansion valve
stem for superheat setting when necessary.

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.

ABNORMAL OPERATION - HEATING

Internal Control Failure

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

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:

• 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
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
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.

Pressure Switch Stuck Open

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 pre­purge 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.

Pressure Switch Stuck Closed

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.

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.

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.

16

MAINTENANCE

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 4 - 6 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”.

17

MAIN BURNER FLAME (QUALIFIED SERVICER ONLY)

Flames should be stable, soft and blue (dust may cause
orange tips but must not be yellow). The flames must extend
directly outward from the burner without curling, floating or
lifting off.

Check the burner flames for:

1. Good adjustment

2. Stable, soft and blue

3. Not curling, floating, or lifting off.
