• 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.

• 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.

• Damper must be in open position when appliance main
burner(s) is operating.

Le registre doit être ouvert lorsque tout brûleur principal
de l’appareil est en état de fonctionnement.

• When the unit is heating, the temperature of the return air
entering the unit must be between 50° F and 100° F.

• Units manufactured on or after May 1, 2017 are not permitted
to be used in Canada for heating of buildings or structures

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. Over firing
of the unit could result in premature heat exchanger failure.

HIGH ALTITUDE DERATE (U.S. INSTALLATIONS ONLY)

IMPORTANT NOTE: Installation of this gas/electric package unit at altitudes above 2000 ft (610 m) shall be made in accordance with

the Listed High Altitude Conversion Kit.
L’installation de ce générateur de chaleur à des altitudes supérieures à 2000 pi (610 m) doit être effectuée conformément aux

instructions accompagnant la trousse de conversion pour haute altitude fournie avec cet appareil.
The gas/electric units naturally derate with altitude. 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.
Use HA02 for installations above 2000’.

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.

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.

Propane Gas Installations

IMPORTANT NOTE: Propane gas conversion kits must be installed
to convert units to propane gas. Refer to the gas piping section
for the correct LP kit for conversion.

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.

WIRING

NOTE: All wiring should be made in accordance with the National Electrical Code.

Consult your local Power Company to determine the availability of sufficient power to operate the unit. Check the voltage,
frequency, and phase at the power supply to ensure it corresponds to the unit’s RATED VOLTAGE REQUIREMENT.
In accordance with the N.E.C. or local codes, install a branch circuit fused disconnect near the unit. Determine wire sizes and
overcurrent protection from the unit nameplate ampacity and in accordance with the Minimum Filter Size or the N.E.C. The wiring
should never be sized smaller than is recommended by either of these two sources.
Fuses smaller than that recommended on the rating plate could result in unnecessary fuse failure or service calls. The use of
protective devices of larger size than indicated could result in extensive damage to the equipment. The manufacturer bears no
responsibility for damage caused to equipment as result of the use of larger than is recommended size protective devices.
All units have undergone a run test prior to packaging for shipment. This equipment has been started at minimum rated voltage and
checked for satisfactory operation. Do not attempt to operate this unit if the voltage is not within the minimum and maximum
voltages shown on nameplate.
All exterior wiring must be within approved weatherproof conduit. The unit must be permanently grounded in accordance with
local codes, or in absence of local codes, with N.E.C. ANSI/
NFPA NO. 70-1984 or latest edition by using ground lug in the
control box.
Fuses or HACR type circuit breakers may be used where codes
permit.
IMPORTANT NOTE: Some single phase units are equipped with a
single-pole contactor. Exercise caution when servicing as only
one leg of the power supply is broken with the contractor.

HIGH VOLTAGE WIRING

The unit transformer is factory connected for 230V operation. If
the unit is to operate on 208V, reconnect the transformer primary
lead as shown on the unit wiring diagram. The induced draft blower
on some models is equipped with a low speed 230V lead (blue) and
a low speed 208V lead (black). If equipped, connect the induced
draft blower low speed 208V lead (black) in place of the low speed
230V lead (blue). Place the unused 230V lead on the “PARK” termi­nal located on ignition control.

• Single Phase. Connect two leads to terminals L1 & L2 in
the electrical control section, using wire sizes specified in
wiring table.

THERMOSTAT CONTROLS

RECOMMENDED: TSTATGTS3275 (Emerson Dual Fuel thermostat) with TSTATTSORS outdoor

temperature sensor.
ALTERNATE: A 1-stage cool/2-stage heat pump thermostat with OTDFPKG-01 outdoor tem-

perature sensor kit.
IMPORTANT NOTE: For optimal performance, an outdoor temperature sensor should be used

with the control thermostat to determine when the unit switches from heat pump mode to
gas mode. The unit is compatible with a standard heat pump thermostat with a minimum of 1
cool - 2 heat. If an outdoor sensor is not installed, the gas will not ignite until the control
thermostat calls for a 2nd stage of heat.

LOW VOLTAGE WIRING

• Heat Pumps. Connect 24V wires from the thermostat to the corresponding wires in
the control box using No. 18 AWG as shown in the table at right:

INTERNAL WIRING

A diagram detailing the internal wiring of this unit is located on the Goodman labeled access panel. If any of the original wire
supplied with the appliance must be replaced, the wire gauge and insulation must be the same as the original wiring.

1. For branch circuit wiring (main power supply to unit disconnect), the minimum wire size for the length of run can be
determined using the circuit ampacity found on the unit rating plate and the table below. From the unit disconnect to the
unit, the smallest wire size allowable may be used for the ampacity, as the disconnect must be in sight of the unit.

2. Wire size based on 60°C rated wire insulation and 30°C Ambient Temperature (86°F).

3. For more than three conductors in a raceway or cable, see the N.E.C. for derating the ampacity of each conductor.
