Pleaseuse these numberswhenrequesting serviceorparts information.
Installation and repair of this unit
should be performed ONLY by in-
dividuals meeting the require-
ments of an "entry level technician", at a minimum, as
specified by the Air-Conditioning, Heating, and Refrigera-
tion Institute (AHRI). Attempting to install or repair this
unit without such background may result in product
damage, personal injury or death.
Goodman will not be responsible

PRODUCT DESIGN
NOTE: Gas furnaces with induced draft blowers draw
productsofcombustion through aheatexchangerallowing,
in some instances, common venting with natural draft
appliances (i.e. water heaters). All installations must be
vented in accordance with National Fuel Gas Code NFPA
54/ANSI Z223.1 - latest edition. In Canada, the furnaces
mustbeventedin accordance with theNationalStandardof
Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest
editionsandamendments.
NOTE: Thevertical height oftheCategory I ventingsystem
must be at least as great as the horizontal length of the
ventingsystem.
2. Linevoltagewiringcanenterthroughtherightorleft side
ofthefurnace. Low voltagewiringcan enter throughthe
rightor leftside of furnace.
3. Conversionkits forhigh altitude natural or propane gas
operation are available. See High Altitude Derate chart
fordetails.
4. Installer must supply the following gas line fittings, de-
pendingon whichentrance is used:
Left -- Two 90º Elbows, one close nipple, straight pipe.
Right --Straight pipe toreach gas valve.
GeneralOperation
GME8furnacesareequipped with anelectronicignition de-
viceusedto light theburnersandan induced draftblowerto
exhaustcombustion products.
Aninterlock switch preventsfurnaceoperation if theblower
door is not in place. Keep the blower access door in place
exceptfor inspection andmaintenance.
This furnace is also equipped with a self-diagnosing elec-
tronic control module. In the event a furnace component is
notoperatingproperly,thecontrolmodule LED will flash on
and off in a factory-programmed sequence, depending on
theproblem encountered. Thislight can beviewed through
theobservation window intheblower access door.Refer to
theTroubleshootingChart for further explanation of theLED
codesandAbnormalOperation - IntegratedIgnitionControl
section in the Service Instructions for an explanation of the
possibleproblem.
Theratedheating capacityofthe furnace shouldbegreater
thanor equalto the totalheat lossof the areato beheated.
The total heat loss should be calculated by an approved
methodor in accordancewith“ASHRAE Guide” or“Manual
J-LoadCalculations”publishedbytheAirConditioningCon-
tractors of America.

LocationConsiderations
• The furnace should be as centralized as is practical
with respect to the air distribution system.
• Donotinstall the furnacedirectlyon carpeting, tile,or
combustiblematerialother thanwoodflooring.
• When suspending the furnace from rafters or joists,
use 3/8" threaded rod and 2” x 2” x 3/8” angle as
shownintheInstallationandServiceInstructions.The
length of the rod will depend on the application and
clearancenecessary.
• When installed in a residential garage, the furnace
mustbepositionedsotheburnersand ignition source
are located not less than 18 inches (457 mm) above
the floor and protected from physical damage by ve-
hicles.
WARNING
TO PREVENT POSSIBLE PERSONAL INJURY OR DEATH DUE TO ASPHYXIATION,
THIS FURNACE MUST BE CATEGORY IVENTED. DO NOT VENT USING
CATEGORY III VENTING.
Notes:
1.Category IVenting is ventingat anon-positive pressure.
A furnace vented as Category I is considered a fan-as-
sisted appliance and the vent system does not have to
be “gas tight.”

HighAltitudeDerate
IMPORTANT NOTE: The furnace as shipped requires no
change to run between 0 - 4500 feet. Do not attempt to
increase the firing rate by changing orifices or increasing
themanifoldpressurebelow4500 feet. This cancausepoor
combustionand equipment failure.
Highaltitudeinstallations above 4500feetmayrequire both
a pressure switch and an orifice change. These changes
are necessary to compensate for the natural reduction in
the density of both the gas fuel and the combustion air at
higheraltitude.
For installations above 4500 feet, please refer to your dis-
tributorforrequiredkit(s).Contactthedistributorforatabular
listing of appropriate manufacturer’s kits for propane gas
and/orhighaltitude installations.Theindicated kits mustbe
used to insure safe and proper furnace operation. All con-
versions must be performed by a qualified installer, or ser-
vice agency.

applications.Thesecoilsareavailableinbothcasedanduncasedmodels(withtheoptionof a field installed TXV expansion
device). These 80% furnaces match up with the existing Amana®brand coils as shown in the chart below.
Coil Matches (for Goodman units using R22 and R-410A):
• All CAPF coils in B, C, & D widths have insulated blank off plates for use with one size smaller furnaces.
• All CAPF coils have a CAUF equivalent.
• All CHPF coils in B, C & D heights have an insulated Z bracket for use with one size smaller furnace.
• All proper coil combinations are subject to being AHRI rated with a matched outdoor unit.

NOTES:
* These furnaces are manufactured for natural gas operation. Optional Kits are available for conversion to propane gas operation.
* 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.
* 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-LOADCALCULATIONS" published by theAIR CONDITIONING CONTRACTORSOF AMERICA. The totalheat loss calculatedshould be equalto or less thanthe heating capacity.

• For most jobs, about 375 - 400 CFM per ton when cooling is desirable.
• Temperature rise data isbasedon2nd-stageheat. First-stageheatis75% of rise indicatedabove.
• INSTAL LA TION IS TO BE ADJUSTED TO OB TAIN TE MP ERATURE RIS E W ITHIN THE RANGE SP ECIFIE D ON THE RATING P LATE .
• This chart is for information only. For satisfactory operation, external static pressure should not exceed value shownon the ratingplate.
• A properly derated unit will have approximately the same temperature rise at a particular CFM, while ESP at the CFM will be lower.
• Factory Motor Speed Setting: T1 = 1st S tage Ht, T2 = 2nd Stage Ht, T5 = Cooling.
