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

suchnon-approved devices.

WARNING

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

GeneralOperation

TheGMV95andGCV9 furnaces are equipped with an elec-

tronicignitiondeviceto light theburnersandaninduceddraft

blowerto exhaust combustion products.

An interlock switch prevents furnace operation if the blower

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

exceptforinspectionand 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

andoffinafactory-programmedsequence, dependingonthe

problem encountered. This light can be viewed through the

observation window in the blower access door. Refer to the

TroubleshootingChartforfurtherexplanationoftheLEDcodes

andAbnormal Operation - IntegratedIgnitionControlsection

intheService Instructions for an explanation ofthe 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-LoadCalculations”publishedbytheAirConditioning Con-

tractorsofAmerica.

BroadwayNewYork, NY10018

LocationConsiderations

• 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

combustiblematerialotherthanwoodflooring.

• When suspending the furnace from rafters or joists,

use3/8"threadedrodand2” x2”x1/8”angleasshown

intheInstallationandServiceInstructions.Thelength

oftherod will depend ontheapplicationandclearance

necessary.

• Wheninstalledina residentialgarage,thefurnacemust

be positioned so the burners and ignition source are

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

floorandprotectedfromphysical damage by vehicles.

Notes:

1. Installermustsupplyoneortwo PVC pipes: one for com-

bustionair(optional) andoneforthe flueoutlet(required).

Vent pipe must be either 2” or 3” in diameter, depending

uponfurnaceinput, number of elbows, lengthof run and

installation (1 or 2 pipes). The optional Combustion Air

Pipeisdependentoninstallation/coderequirementsand

must be 2” or 3” diameter PVC.

2. Linevoltagewiringcanenterthroughtherightorleftside

rightor left side of furnace.

FURNACE SPECIFICATIONS

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

2. For elevations above 2000 feet the rating should be reduced by 4% for each 1000 feet 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 manufacturers method or 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.

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

Unit specifications are subject to change without notice. ALWAYS refer to the units serial plate for the most up-to-date general and electrical information.

(1) Wire size should be determined in accordance with National Electrical Codes. Extensive wire runs will require larger wire sizes.

(2) Maximum Overcurrent Protection Device: May use Time Delay Fuse or HACR type Circuit Breaker of the same size as noted.

(3) Off Heating - this fan delay timing is adjustable (90, 120, 150 and 180 seconds). Furnaces are shipped with 150 second off delay.

(4) See Installation Instructions for appropriate vent diameter, length and number of elbows.

(5) See Installation Instructions for appropriate combustion air pipe diameter, length and number of elbows.
