WARNING

HIGH VOLTAGE!

Disconnect ALL power before servicing or installing this unit. Multiple

power sources may be present. Failure to do so may cause property

damage, personal injury or death.

Installation and repair of this unit should be performed ONLY by individu-

als meeting the requirements of an "entry level technician" as specified

by the Air Conditioning and Refrigeration Institute (ARI). Attempting to

install or repair this unit without such background may result in product

damage, personal injury or death.

WARNING

Goodman will not be responsibile for any injury or property damage arising

from improper service or service procedures. If you install or perform

service on this unit, you assume responsibility for any personal injury or

property damage which may result. Many jurisdictions require a license to

install or service heating and air conditioning equipment.

WARNING

WARNING To prevent the risk of property damage, personal injury, or death, do not

store combustible materials or use gasoline or other flammable liquids or

vapors in the vicinity of this appliance.

Do not connect or use any device that is not design certified by Goodman

for use with this unit. Serious property damage, personal injury, reduced

unit performance and/or hazardous conditions may result from the use of

such non-approved devices.

WARNING

WARNING The United States Environmental Protection Agency (“EPA”) has issued vari-

ous regulations regarding the introduction and disposal of refrigerants intro-

duced into this unit. Failure to follow these regulations may harm the envi-

ronment and can lead to the imposition of substantial fines. These regula-

tions may vary by jurisdiction. Should questions arise, contact your local EPA

office.

High Altitude Derate

When this furnace is installed at high altitude, the appropri-

ate High Altitude orifice kit must be installed. This is re-

quired due to the natural reduction in the density of both

the gas fuel and combustion air as altitude increases. The

kit will provide the proper design certified input rate within

the specified altitude range.

High altitude kits are purchased according to the installa-

tion altitude and usage of either natural or propane gas.

Refer to the chart above for a tabular listing of appropriate

altitude ranges and corresponding manufacturer’s high al-

titude Natural Gas and Propane Gas kits. For a tabular list-

ing of appropriate altitude ranges and corresponding

manufacturer's High Altitude Pressure Switch kits, refer to

either the Pressure Switch Trip Points & Usage Chart in

this manual or the Accessory Charts in Service Instruc-

tions.

General Operation

The AMV9 and ACV9 furnaces are equipped with an elec-

tronic ignition device to light the burners and an induced

draft blower to exhaust combustion products.

An interlock switch prevents furnace operation if the blower

door is not in place. Keep the blower access doors in place

except for inspection and maintenance.

This furnace is also equipped with a self-diagnosing elec-

tronic control module. In the event a furnace component is

not operating properly, the control module LED will flash on

and off in a factory-programmed sequence, depending on

the problem encountered. This light can be viewed through

the observation window in the blower access door. Refer to

the Troubleshooting Chart for further explanation of the LED

codes and Abnormal Operation - Integrated Ignition Con-

trol section in the Service Instructions for an explanation of

the possible problem.

The rated heating capacity of the furnace should be greater

than or equal to the total heat loss of the area to be heated.

The total heat loss should be calculated by an approved

method or in accordance with “ASHRAE Guide” or “Manual

J-Load Calculations” published by the Air Conditioning Con-

tractors of America.

*Obtain from: American National Standards Institute 1430

Broadway New York, NY 10018

Location Considerations

• The furnace should be as centralized as is practical

with respect to the air distribution system.

• Do not install the furnace directly on carpeting, tile,

or combustible material other than wood flooring.

• When suspending the furnace from rafters or joists,

use 3/8" threaded rod and 2” x 2” x 1/8” angle as

shown in the Installation and Service Instructions. The

length of the rod will depend on the application and

clearance necessary.

• When installed in a residential garage, the furnace

must be positioned so the burners and ignition source

are located not less than 18 inches (457 mm) above

the floor and protected from physical damage by ve-

hicles.

Notes:

1. Installer must supply one or two PVC pipes: one for

combustion air (optional) and one for the flue outlet (re-

quired). Vent pipe must be either 2” or 3” in diameter,

depending upon furnace input, number of elbows, length

of run and installation (1 or 2 pipes). The optional Com-

bustion Air Pipe is dependent on installation/code re-

quirements and must be 2” or 3” diameter PVC.

2. Line voltage wiring can enter through the right or left

side of the furnace. Low voltage wiring can enter through

the right or left side of furnace.

3. Conversion kits for propane gas and high altitude natu-

ral and propane gas operation are available. See High

Altitude Derate chart for details.

Filters:

Filters are required with this furnace and must be provided by the installer. The filters used must comply with UL900 or

CAN/ULCS111 standards. Installing this furnace without filters will void the unit warranty

Upflow Filters

FURNACE SPECIFICATIONS

1. These furnaces are manufactured for natural gas operation. Optional Kits are available for conversion to propane gas operation.

2. For elevations above 2000 ft. the rating should be reduced by 4% for each 1000 ft. above sea level. The furnace must not be

derated, orifice changes should only be made if necessary for altitude.

3. The total heat loss from the structure as expressed in TOTAL BTU/HR must be calculated by the manufactures method in

accordance with the "A.S.H.R.A.E. GUIDE" or "MANUAL J-LOAD CALCULATIONS" published by the AIR CONDITIONING

CONTRACTORS OF AMERICA. The total heat loss calculated should be equal to or less than the heating capacity. Output

based on D.O.E. test procedures, steady state efficiency times output.

4. Minimum Circuit Ampacity calculated as: (1.25 x Circulator Blower Amps) + I.D. Blower Amps.
