TO PREVENT THE RISK OF PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH,
DO NOT STORE COMBUSTIBLE MATERIALS OR USE GASOLINE OR OTHER
FLAMMABLE LIQUI DS OR VAPORS I N THE V ICINIT Y OF THI S APPL IANCE.
Special Warning for Installation of Furnaces or A ir Handling Units i n
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 oper ated therein, there must be adequate, direct outside
ventilation.
UNIT LOCATION
WARNING
O PREVENT POSSIBLE EQUIPMENT DAMAGE, PROPERTY DAMAGE, PERSONAL
T
INJURY OR DEATH, THE FOLLOWING BULLET POINTS MUST BE OBSERVED
WHEN INSTALLING THE UNIT.
ALL INSTALLATIONS:
• For proper flame pattern within the heat exchanger and
proper condensate drainage, the unit must be mounted
level.
• The flue outlet hood must be at least 12 inches from any
opening through which flue gases could enter a building,
and at least three feet above any forced air inlet located
within ten feet. The economizer/manual fresh air intake/
motorized fresh air intake and combustion air inlet
mounted on the unit are not affected by this restriction.
• To avoid possible corrosion of the heat exchanger, do not
locate the unit in an area where the outdoor air (i.e.
combustion air for the unit) will be frequently contaminated
by compounds containing chlorine or fluorine. Common
sources of such compounds include swimming pool
chemicals and chlorine bleaches, paint stripper,
adhesives, paints, varnishes, sealers, waxes (which are
not yet dried) and solvents used during construction and
remodeling. Various commercial and industrial processes
may also be sources of chlorine/fluorine compounds.
• 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.
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.
• The base should also be located where no runoff of water
from higher ground can collect in the unit.
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 enclose d area. Carbon monox ide emissions can be (re)circulated
throughout t he structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.

weight of the unit(s) and snow or water loads as required
by local codes. Consult a structural engineer to determine
the weight capabilities of the roof.
ROOF CURB INSTALLATIONS ONLY:
• Sufficient structural support must be determined prior to
locating and mounting the curb and package unit.
• Ductwork must be constructed using industry guidelines.
The duct work must be placed into the roof curb before
mounting the package unit.
• Curb insulation, cant strips, flashing and general roofing
material are furnished by the contractor.

O FACILITATE
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.
Inlet Gas Pressure Must Not Exceed the Maximum Value Shown in Table
Above.
The minimum supply pressure should not vary from that shown in
the table above because this could prevent the unit from having
dependable ignition. In addition, gas input to the burners must not
exceed the rated input shown on the rating plate. Overfiring of the
unit could result in premature heat exchanger failure.
HIGH ALTITUDE DERATE (U.S. INSTALLATIONS ONLY)
IMPORT ANT NOTE: The gas/electric units naturally derate with al-
titude. Do not attempt to increase the firing rate by changing orifices or increasing the manifold pressure. This can cause poor combustion and equipment failure. At all altitudes, the manifold pressure must be within 0.3 inches W.C. of that listed on the nameplate
for the fuel used. At all altitudes and with either fuel, the air temperature rise must be within the range listed on the unit nameplate.
Refer to the Installation Manual provided with the LP kit for conversion from natural gas to propane gas and for altitude adjustments.

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.
TANKS AND PIPING
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.

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
for horizontal duct
applications

BUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIR
FILTER INSTALLED IN THE RETURN AIR SYSTEM.
Even though a return air filter is not supplied with this unit,
there must be a means of filtering all return air. All units may
be externally filtered.
Refer to the unit filter size chart in the appendix for filter size
information.
Filters installed external to the unit should be sized in
accordance with their manufacturer recommendations. A
throwaway filter must be sized for a maximum face velocity of
300 feet per minute.

VENTING
NOTE: Venting is self-cont ained. Do not modify or block.
FLUE HOOD INSTALLATION
Install the exhaust flue hood and combustion air intake hood
prior to operation of the unit.
To install the flue hood cover, please refer to IO-653*, included
in the flue hood assembly box located in the blower
compartment.
2. The spark igniter and gas valve energizes for 7 seconds.
NOTE: The igniter produces a very intense electrical spark
that ignites the gas.
3. The 30-second HEAT FAN ON delay time begins.
4. The unit delivers heat to the conditioned space until the
thermostat is satisfied.
5. The gas valve deenergizes. The induced draft blower
continues operation for a 29-second post-purge.
6. Ignition control begins timing the HEAT FAN OFF delay.
There is an adjustable HEAT FAN OFF delay of
approximately 120/135/150 seconds (factory set at 150).
After the HEA T F AN OFF delay time has elapsed, the blower
will deenergize. This allows any additional heat in the
heat exchanger to be transferred to the conditioned space.
COOLING
1. Thermostat calls for cooling. The compressor and outdoor
fan are energized.
2. Approximately seven seconds later, the indoor fan starts.
3. The unit will deliver cooling to the conditioned space until
the thermostat is satisfied.
4. The compressor and outdoor fan will be de-energized
when the thermostat opens.
5. The indoor fan continues to run 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 fan stops.

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. Thermostat calls for heat. The induced draft blower
energizes for a 15-second pre-purge.
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. Approximately seven seconds later, the indoor fan starts.
3. The indoor fan continues to run for approximately 60
seconds after “G” is de-energized.
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.
