•

•
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.

•

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.
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:

•

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.

•

CO can cause serious illness including permanent brain damage or death.

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.
The base should also be located where no runoff of water
from higher ground can collect in the unit.

GAS PIPING CHECKS

Refer to the Proper Piping Practice drawing for the general layout
at the unit. The following rules apply:
1. Use black iron pipe and fittings for the supply piping. The
use of a flex connector and/or copper piping is permitted
as long as it is in agreement with local codes.
2. Use pipe joint compound on male threads only. Pipe joint
compound must be resistant to the action of the fuel used.
3. Use ground joint unions.
4. Install a drip leg to trap dirt and moisture before it can enter
the gas valve. The drip leg must be a minimum of three
inches long.
5. Use two pipe wrenches when making connection to the gas
valve to keep it from turning.
6. Install a manual shut-off valve in a convenient location
(within six feet of unit) between the meter and the unit.
7. Tighten all joints securely.
8. The unit must be connected to the building piping by one
of the following methods:
• Rigid metallic pipe and fittings
• Semirigid metallic tubing and metallic fittings (Aluminum
alloy tubing must not be used in exterior locations)
• 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)

CAUTION
TO PREVENT PROPERTY DAMAGE OR PERSONAL INJURY DUE TO FIRE, THE
FOLLOWING INSTRUCTIONS MUST BE PERFORMED REGARDING GAS
CONNECTIONS AND PRESSURE TESTING:
•

THE UNIT AND ITS GAS CONNECTIONS MUST BE LEAK TESTED BEFORE
PLACING IN OPERATION. BECAUSE OF THE DANGER OF EXPLOSION OR
FIRE, NEVER USE A MATCH OR OPEN FLAME TO TEST FOR LEAKS. NEVER
EXCEED SPECIFIED PRESSURES FOR TESTING. HIGHER PRESSURE MAY
DAMAGE GAS VALVE AND CAUSE OVERFIRING WHICH MAY RESULT IN
PREMATURE HEAT EXCHANGE FAILURE.

•

THIS UNIT AND ITS SHUT-OFF VALVE MUST BE DISCONNECTED FROM
THE GAS SUPPLY DURING ANY PRESSURE TESTING OF THAT SYSTEM AT
TEST PRESSURES IN EXCESS OF 1/2 PSIG (3.48 KPA).

•

THIS UNIT MUST BE ISOLATED FROM THE GAS SUPPLY SYSTEM BY
CLOSING ITS MANUAL SHUT-OFF VALVE DURING ANY PRESSURE
TESTING OF THE GAS SUPPLY PIPING SYSTEM AT TEST PRESSURES
EQUAL TO OR LESS THAN 1/2

PSIG (3.48 KPA).

WARNING
TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY, BE

SURE THERE IS
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
placed in operation by closing the main electrical disconnect
switch for the unit.

GAS DETECTING WARNING DEVICE.

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. Vaporization 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.

GROMMET

Proper Piping Practice
NOTE: The unit gas supply entrance is factory sealed with plugs.
Keep plugs in place until gas supply is ready to be installed. Once
ready, replace the plugs with the supplied grommets and install gas
supply line.

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:

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.
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.
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 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.

Gas Input (Natural Gas Only) Check

With Power And Gas On:

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.

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

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

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.
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.

NOTE: Heating airflow must be adjusted to provide the temperature rise shown on rating plate.
*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.

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.

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

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.

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

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:
• 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.

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.

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.
NOTE: After cleaning, the microamp signal should be stable and in
the range of 4 - 6 microamps DC.

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

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”.

MAIN BURNER FLAME (QUALIFIED SERVICER ONLY)

CAUTION

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.

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.

Check the burner flames for:
1. Good adjustment
2. Stable, soft and blue
3. Not curling, floating, or lifting off.
