Application
TheICM283UniversalHotSurfaceIgnitionModuleisareplacementforawiderangeofhotsurface
ignitionmodules.TheICM283providescontrolofadirectignitionsystemusinga120VAChot
surfaceigniter.TheICM283replacesexistingamerecticationtypehotsurfaceignitionmoduleswith
thefollowingcharacteristics:
• 120VAC(upto5A)timedhotsurfaceignition
• Singlerod(localsense)ordualrod(remotesense)hotsurfaceignitionsystems
• Oneorthreeignitiontrialsperheatcall
• Four-secondorseven-secondignitiontrials
• Prepurgeof32secondsorless
• Upto96secondsbetweentrialpurgetimes(three-trials)
• NaturalorLPgas
TheICM283packagecontainstheICM283controlmodule,theapplicationguide,andtheaccessories
requiredtoadapttooldersystems.
Installation Warnings
1. Read these instructions carefully.FailuretofollowtheseInstructionscoulddamagethemodule
orcauseahazardouscondition.Installermustbeatrained,qualiedservicetechniciancapableof
workingwithliquidpropane,naturalgasandhighvoltageelectricity.
2. VerifythattheICM283isthecorrectreplacementforthemoduleinyoursystem.
3. Never installwherewatercanood,driporcondenseonthemodule.Neveruseamodule
thathasbeenwet.Replaceit.Iftheignitionmodulegetswet,itcanmalfunction,leadingto
accumulationofexplosivegas.Donotattempttodisassembleorcleanthemodule.Improper
reassemblyandcleaningcancauseamalfunctionorunreliableoperation.Ifamodulemustbe
mountedwhereitcanbeexposedtomoistureorwater,provideasuitablewaterproofenclosure.it
isbesttomountthecontrolwiththeterminalsdowntoavoidwatergettingontomodule.
4. Disconnect the powersupplybeforebeginningwiringtopreventelectricalshockorequipment
damage.
5. Turn off the gas supplybeforestartingtheinstallation.Ifyousmellgasorsuspectagas
leak,turnoffgasatthemanualservicevalveandevacuatethebuilding.Donottrytolightany
appliance;donottouchanyelectricalswitchortelephoneinthebuildinguntilyouaresurenogas
remains.
6. Do not lightthepilotoroperateelectricswitches,lightsorappliancesuntilyouaresurethe
applianceareaisfreeofgas
7. Usingthewirelabelsprovided,labelallthewiresbeforedisconnecting.Wiringerrorscancause
improperapplianceoperation,ignitionmoduledamageanddangerousconditions(suchas
bypassingsafetyfeatures).
8. Improperlocationofthe120VAChotsurfaceigniteroranyamesensingrodcanresultin
appliancemalfunction.
9. Neverattempttorelocatethe120VAChotsurfaceigniterortheamesensingrodfromtheoriginal
positionestablishedbytheappliancemanufacturer.
10.Besurethe120VAChotsurfaceigniterortheamesensingrodisreplacedinexactlytheoriginal
positionafterremovalforinspection,serviceorreplacement.
Remove Old Module
Disconnectthepowersupplyandturnoffgasatshutoffvalvebeforedoinganyworkontheunit.
Disconnectandtagthewiresfromtheoldmoduleusingthewirelabelsprovided.Removetheold
modulefromitsmountinglocation.
ICM283 Mount Instructions
MounttheICM283Moduleinthesamelocationastheoldmodule.Protectthemodulefromexposure
towater,moisture,corrosivechemicalsandexcessivedustandgrease.Assurethatambient
temperatureatthemoduleiswithintherangelistedabove.
Mountthemodulewiththeterminalsdowntoprotectfromdrippingwateranddust.Themodulecan
alsobemountedwithterminalsoneitherside.Donotmountwiththeterminalspointingup.Whenit
isnecessarytodrillnewmountingholes,usetheICM283asatemplatetomarkthemountinghole
pattern.Drillnewholesasrequired.Usecautionwhiledrillingtoavoiddamagingwires,gaslines,
heatexchanger,etc.FastensecurelywithfourNo.6-32machineorNo.8sheetmetalscrews.
Set the Dip Switches
Youmustsetthedipswitchescorrectlytomatchyoursystem.SeeICM283CrossReferenceCharton

Notes:If you smell gas or suspect a gas leak, turn off gas at the manual service valve and evacuate
the building. Do not try to light any appliance; do not touch any electrical switch or telephone
in the building until you are sure no gas remains.
The Gas leak Test must be done for initial installation and any time work is done involving
the gas lines or equipment.
