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.
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.

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)
IMPORTANT NOTE: 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.
PIPING
IMPORTANT NOTE: To avoid possible unsatisfactory operation or equipment damage due to under firing of equipment, do not undersize the natural/propane gas piping from the meter/tank to the unit. When sizing a trunk line, include all appliances on that line that could be operated simultaneously.
The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the unit is equipped to operate on the type of gas available. The gas line installation must comply with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1.

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)

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.
GAS PIPING CHECKS
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.
PROPANE GAS INSTALLATIONS
WARNING
TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE OR EXPLOSION CAUSED BY A PROPANE GAS LEAK, INSTALL A GAS DETECTING WARNING DEVICE. SINCE RUST CAN REDUCE THE LEVEL OF ODORANT IN PROPANE GAS, A GAS DETECTING WARNING DEVICE IS THE ONLY RELIABLE WAY TO DETECT A PROPANE GAS LEAK. CONTACT A LOCAL PROPANE GAS SUPPLIER ABOUT INSTALLING A 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.
7
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.
See below for typical propane gas piping.

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.
ELECTRICAL WIRING
THERMOSTAT LOCATION
Mount the thermostat approximately five feet above the floor, in an area that has an inside, vibration-free wall and has good air circulation.
Movement of air must not be obstructed by furniture, door, draperies, etc. The thermostat must not be mounted where it will be affected by drafts, hot or cold water pipes or air ducts in walls, radiant heat from fireplace, lamps, the sun, television, etc. Consult the Instruction Sheet packaged with thermostat for mounting instructions.
All units have one stage of heating and one stage of mechanical cooling. Units which will have economizers may use thermostats with one or two stages of cooling.
*PG1360***1A ONLY: These models have two stages of mechanical cooling. A 1-stage heat, 2-stage cooling thermostat is recommended for these models.
The units are designed for operation on 60 hertz current and at voltages as shown on the rating plate. All internal wiring in the unit is complete. It is necessary to bring in the power supply to the contactor as shown on the unit wiring diagram which is supplied with each unit. 24 volt wiring must be connected between the unit control panel and the room thermostat.

Low Voltage Wiring-*PG1360***1A Only
Refer to the unit wiring diagram for electrical connections. When installed, the unit must be electrically grounded in accordance with local codes or in the absence of local codes, with the National Electrical Code, ANSI/NFPA No. 70, and/or the CSA C22.1 Electrical Code. Ensure low voltage connections are waterproof.
WARNING
TO AVOID THE RISK OF ELECTRICAL SHOCK, WIRING TO THE UNIT MUST BE POLARIZED AND GROUNDED.
CAUTION
TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY DUE TO FIRE, USE ONLY COPPER CONDUCTORS.
CAUTION
TO PREVENT IMPROPER AND DANGEROUS OPERATION DUE TO WIRING ERRORS, LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. VERIFY PROPER OPERATION AFTER SERVICING.
For unit protection, use a fuse or HACR circuit breaker that is in excess of the circuit ampacity, but less than or equal to the maximum overcurrent protection device. DO NOT EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT DATA PLATE.
All line voltage connections must be made through weatherproof fittings. All exterior power supply and ground wiring must be in approved weatherproof conduit. Low voltage wiring from the unit control panel to the thermostat requires coded cable. See below for ground level and rooftop wiring.
Note:Junction box location shown is optional and is
for illustration purposes only.
JUNCTION BOX
Electrical Power Directly To Junction Box

Typical Electrical Wiring Unit Voltage
UNIT VOLTAGE
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 230V lead (red) and a 208V lead (black). If equipped, connect the induced draft blower 208V lead (black) in place of the 230V lead (red). Tape the unused 230V lead.
HEAT ANTICIPATOR SETTING
The heat anticipator is to be set by measuring the load (amperage) at the “R” circuit. Follow the instructions provided by the thermostat for more details.

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.
Remove these covers for horizontal duct applications
Duct Cover Installation
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.
FILTERS
CAUTION
TO PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OF EQUIPMENT EFFICIENCY OR EQUIPMENT DAMAGE DUE TO DUST AND LINT 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. The *PG1336(3A,4A), *PG1342, *PG1348, and *PG1360 models are provided with internal filter racks for down-discharge applications. 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.
Filter Installation
Important: When installing a filter, the air flow arrows on the filter must point toward the circulator blower.

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.
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. *PG13(48,60)***1A ONLY: Heat on delay begins when thermostat calls for heat. ECM motor is energized approximately 45 seconds later. NOTE: ECM motor may operate at approximately 100 CFM or less during the 45 second on delay period. ECM motor will energize at heating speed after the 45 second delay regardless of the status of the main burner flame.
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 HEAT FAN 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. *PG13(48,60)***1A ONLY: HEAT FAN OFF delay is fixed at 180 seconds. Airflow level is 50% of nominal heating airflow.
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 deenergized 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.
*PG1348***1A ONLY:
1.Thermostat calls for cooling. Outdoor fan and compressor are energized. ECM motor is energized almost immediately for 30 seconds at 50% of the nominal airflow. Airflow then increases to nominal airflow.
2.The unit will deliver cooling to the conditioned space until thermostat is statisfied.
3.The outdoor fan and compressor will be de-energized when thermostat opens.
4.ECM motor continues to operate for approximately 60 seconds at 50% of nominal airflow after thermostat opens.
*PG1360***1A ONLY:
1.Thermostat calls for low stage cooling. Outdoor fan and low stage compressor are energized. ECM motor is energized almost immediately for 30 seconds at 50% of the nominal low stage airflow. Airflow then increases to nominal low stage airflow.
If thermostat calls for high stage cooling, outdoor fan and low and high stage compressor is energized. ECM motor is energized almost immediately for 30 seconds at 50% of the nominal high stage airflow. Airflow then increases to nominal high stage airflow.
2.The unit will deliver cooling to the conditioned space until thermostat is satisfied.
3.The outdoor fan and low stage compressor (or low and high stage compressor) will be de-energized when thermostat opens.
4.ECM motor continues to operate for approximately 60 seconds at 50% of nominal low stage airflow (or high stage airflow if thermostat call was for high stage cooling) after thermostat opens.
11
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.
*PG13(48,60)***1A ONLY:
1.Thermostat calls for FAN ONLY by energizing “G”.
2.ECM motor is energized almost immediately at approximately 30% of the nominal high stage cooling airflow, depending on setting (see “Blower Speed Adjustment” section).
3.ECM is de-energized almost immediately after “G” is deenergized.
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
TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE OR EXPLOSION, A QUALIFIED SERVICER MUST INVESTIGATE THE REASON FOR THE ROLLOUT PROTECTION DEVICE TO OPEN BEFORE MANUALLY RESETTING THE ROLLOUT PROTECTION DEVICE.

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.

Pre-Operation Checks
1.Close the manual gas valve external to the unit.
2.Turn off the electrical power supply to the unit.
3.Set the room thermostat to its lowest possible setting.
4.Remove the heat exchanger door on the side of the unit by removing screws.
5.This unit is equipped with an ignition device which automatically lights the main burner. DO NOT try to light burner by any other method.
6.Move the gas control valve switch to the OFF position. Do not force.
7.Wait five minutes to clear out any gas.
8.Smell for gas, including near the ground. This is important because some types of gas are heavier than air. If you have waited five minutes and you do smell gas, immediately follow the warnings on page 3 of this manual.
