POISONING

HAZARD

B10259-216

Carbon monoxide producingdevices(such as an automobile, space

heater, gas water heater, etc.) shouldnot 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. Ifa furnace or airhandleris installed inan enclosedarea 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 poisoningwhich

can occur if a carbon monoxide producingdevice continues to operate in

the enclosed area. Carbon monoxide emissions can be (re)circulated

throughout thestructure if the furnace or air handleris operating inany

mode.

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

GAS PIPING

IMPORTANT NOTE: This unit is factory set to operate on natural

gas at the altitudes shown on the rating plate.

WARNING

TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH WHEN EITHER

USING PROPANE GAS ALONE OR AT HIGHER ALTITUDES, OBTAIN AND INSTALL

THE PROPER CONVERSION KIT(S). FAILURE TO DO SO CAN RESULT IN

UNSATISFACTORY OPERATION AND/OR EQUIPMENT DAMAGE. HIGH ALTITUDE

KITS ARE FOR U.S. INSTALLATIONS ONLY AND ARE NOT APPROVED FOR USE

IN CANADA.

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. Conversion to LP gas is permitted with the

use of the factory authorized conversion kit LPT-00A.

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)

IMPORTANT NOTE: The gas/electric units naturally derate with al-

titude. Do not attempt to increase the firing rate by changing ori-

fices or increasing the manifold pressure. This can cause poor com-

bustion and equipment failure. At all altitudes, the manifold pres-

sure 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 tempera-

ture rise must be within the range listed on the unit nameplate.

Refer to the Installation Manual provided with the LP kit for conver-

sion 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 under-

size 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

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 twopipe wrencheswhen makingconnection to thegas

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

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

standardsoftheNational BoardofFireUnderwriters (SeeNBFU

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.

WARNING

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:

• 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

THERMOSTATLOCATION

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

theunit iscomplete. It isnecessary tobring inthe powersupply

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.

TANKS AND PIPING

Complete information regarding tank sizing for vaporization,

recommended regulator settings and pipe sizing is available

frommost regulator manufacturersand propanegas 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.

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 DATAPLATE.

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.

CIRCULATING AIR AND FILTERS

AIRFLOW CONVERSION

Units can easily be converted from horizontal to down-

discharge 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

DuctCoverInstallation

DownDischargeApplications

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 DUETO 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.
