2 - DESCRIPTION
Caldariello Condens KIS is a Type C wall-mounted condensing boiler
designed for heating and production of domestic hot water: according to
theuegasdischargedevice,theboilerisclassiedincategoriesB23P,
B53P,C13,C13x;C23(whererequired);C33,C33x;C43,C43x;C53,C53x;
C63,C63x;C83,C83x;C93,C93x.
IncongurationB23PandB53P(wheninstalledindoors),theappliance
cannot be installed in bedrooms, bathrooms, showers or where there are
open replaces without a proper air ow. The room where the boiler is
installedmusthaveproperventilation.
IncongurationC,theappliancecanbeinstalledinanytypeofroomand
therearenolimitationsduetoventilationconditionsorroomvolume.
3 - INSTALLATION
3.1 - Installation regulations
Installationmustbecarriedoutbyqualiedpersonnel,inaccordancewith
localregulations.
POSITION
The boiler has protection that guarantees correct operation with a tem-
peraturerangefrom0°Cto60°C.
To takeadvantage ofprotective devices,the appliancemustbeableto
startup,sinceanylockoutcondition(forexample,absenceofgasorelec-
tricalsupply,orsafetyoperation)deactivatestheprotectivedevices.Ifthe
machine is left powered down for long periods in areas where tempera-
turesmayfallbelow0°C,andyoudonotwanttodraintheheatingsystem,
youareadvisedtoaddagoodqualityantifreezeliquidtotheprimarycircuit
toprotectitfromfreezing.
Carefullyfollowthemanufacturer'sinstructionswithregardsnotonlythe
percentageofantifreezeliquidtobeusedfortheminimumtemperature
atwhichyouwanttokeepthemachinecircuit,butalsothedurationand
disposaloftheliquiditself.Forthedomestichotwaterpart,werecommend
youdrainthecircuit.
Theboilercomponentmaterialsareresistanttoethyleneglycolbasedan-
tifreezeliquids.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance op-
erations,respecttheminimumclearancesforeseenforinstallation(g.9).
For correct appliance positioning:
- donotplaceitonacookerorothercookingdevice
- donotleaveinammableproductsintheroomwheretheboilerisinstalled
- heatsensitivewalls(forexample,woodenwalls)mustbeprotectedwith
properinsulation.
IMPORTANT
Beforeinstallation,washallsystempipingcarefullyinordertoremoveany
residuesthatmayimpairtheoperationoftheappliance.
Connectthedrainmanifoldtoasuitabledrainagesystem(fordetails,refer
to chapter 3.5). The domestic hot water circuit does not need a safety
valve,butmakesurethatthepressureofwaterworksdoesnotexceed6
bar.Incaseofdoubts,installapressurereducer.Priortoignition,make
sure that the boiler is designed to operate with the gas available; this can
becheckedbythemessageonthepackagingandtheadhesivelabelindi-
catingthegastype.Itisveryimportanttohighlightthatinsomecasesthe

ed, observing the following indications:
itmustbemountedonthesideofthebuildingmostoftenexposedtowinds
(theNORTHorNORTHWESTfacingwall),avoidingdirectsunlight;itmust
bemountedabouttwothirdsofthewayupthewall;
it must not be mounted near doors, windows or air outlet points, and must
bekeptawayfromsmokepipesorotherheatsources.
Theelectricalwiringtotheexternalsensorismadewithabipolarcable
withasectionfrom0.5to1mm2 (notsupplied),withamaximumlength
of30metres.Itisnotnecessarytorespectthepolarityofthecablewhen
connectingittotheexternalsensor.Avoidmakinganyjointsonthiscable
however;ifjointsareabsolutelynecessary,theymustbewatertightand
well protected.Any ducting of the connection cable must be separated
fromlivecables(230VAC).
FIXING THE EXTERNAL SENSOR TO THE WALL
Thesensormustbexedonasmoothpartofthewall;inthecaseofex-
posedbrickworkoranunevenwall,lookforthesmoothestpossiblearea.
Loosentheplasticupperprotectivecoverbyturningitanticlockwise.

3.12 Flue gas discharge and air suction
Observelocallegislationregardinguegasdischarge.
Flue gases are discharged from a centrifugal fan located inside the com-
bustion chamber and the control board constantly checks that this is
workingcorrectly.The boiler issuppliedwithout the uegasdischarge/
air suction kit, since it is possible to use the accessories for appliance
with a forced draught sealed chamber that better adapts to the installation
characteristics.
Foruegasextractionand therestorationof boilercombustionair, itis
essentialtoonlyusecertiedpiping.Connectionmustbecarriedoutcor-
rectlyasindicatedintheinstructionssuppliedasstandardwiththeuegas
accessories.
Multipleappliancescanbeconnectedtoasinglesmokepipeprovidedthat
eachisasealedchamber-typeappliance.
Theboileris aTypeCappliance(sealedchamber),andmusttherefore
haveasafeconnectiontotheuegasdischargepipeandtothecombus-
tionairsuctionpipe;thesebothcarrytheircontentsoutside,andarees-

TYPE OF HEAT REQUEST
Boiler connected to room thermostat (JUMPER 6 not inserted)
Theheatrequestismadebytheclosureoftheroomthermostatcontact,
whiletheopeningofthecontactproducesaswitch-off.Thedeliverytem-
peratureisautomaticallycalculatedbytheboiler,althoughtheusermay
modifytheboilersettings.UsingtheinterfacetomodifytheHEATING,you
will not have the HEATING SET-POINT value available, but a value that
youcansetaspreferredbetween15and25°C.Themodicationofthis
valuewillnotdirectlymodifythedeliverytemperature,butwillautomati-
callyaffectthecalculationthatdeterminesthevalueofthattemperature,
alteringthereferencetemperatureinthesystem(0=20°C).
Boiler connected to a programmable timer (JUMPER JP6 inserted)
With the contact closed, the heat request is made by the delivery sen-
sor,onthebasisoftheexternaltemperature,toobtainanominalindoor
temperatureonDAYlevel(20°C).Withthecontactopen,theboilerisnot
switchedoff,but the weathercurveis reduced(parallelshift) toNIGHT
level(16°C).
Thisactivatesthenight-timefunction.
Thedeliverytemperatureisautomaticallycalculatedbytheboiler,although
theusermaymodifytheboilersettings.
UsingtheinterfacetomodifytheHEATING,youwillnothavetheHEAT-
INGSET-POINTvalueavailable,butavaluethatyoucansetaspreferred
between25and15°C.

ture,butwillautomaticallyaffectthecalculationthatdeterminesthevalue
ofthattemperature,alteringthereferencetemperatureinthesystem(0=
20°CforDAYlevel,and16°CforNIGHTlevel).
4.6 Adjustments
Theboilerhasalreadybeenadjustedbythemanufacturerduringproduc-
tion.Iftheadjustmentsneedtobemadeagain,forexampleafterextraor-
dinary maintenance, replacement of the gas valve, or conversion from
methanegastoLPG,observethefollowingprocedures.
Theadjustmentofthemaximumand minimumoutput,andofthemaxi-
mumandminimumheatingandofslowswitch-on,mustbemadestrictlyin
thesequenceindicated,andonlybyqualiedpersonnelonly:
- disconnecttheboilerfromthepowersupply
- turntheheatingwatertemperatureselectortoitsmaximum
- loosenthexingscrews(E)ontheinstrumentpanel(g.14)
- liftthenturntheinstrumentpaneltowardsyou
- loosenthexingscrewsonthecover(F)toaccesstheterminalboard
(g.16)
- insertthejumpersJP1andJP3(g.39)
- poweruptheboiler.
ThethreeLEDsontheinstrumentpanelashsimultaneouslyandthedis-
playshows“ADJ”forapproximately4seconds.
Nextchangethefollowingparameters:
1-Domestichotwater/absolutemaximum
2 - Minimum
3-Heatingmaximum
4 - Slow switch-on
as follows:
- turn the heating water temperature selector to set the required value
- presstheCObutton(g.26)andthenskiptothecalibrationofthenext
parameter.

The following icons light up on the monitor:
1.  duringdomestichotwater/absolutemaximumcalibration
2. during minimum calibration
3.  duringheatingmaximumcalibration
4. during slow switch-on calibration
EndtheprocedurebyremovingjumpersJP1andJP3tostoretheseset
valuesinthememory.
Thefunctioncanbeendedatanytimewithoutstoringthesetvaluesinthe
memoryandretainingtheoriginalvaluesasfollows:
- removejumpersJP1andJP3beforeall4parametershavebeenset
- set the function selector to (OFF/RESET)
- cutthepowersupply
- waitingfor15minutesafteritisconnected.
 Calibrationcanbecarriedoutwithoutswitchontheboiler.
 Byturningtheheatingselection knob,themonitorautomatically
showsthenumberofrotations,expressedinhundreds(e.g.25=
2,500rpm).
Note: the meter resetting procedure should be carried out after each in-
depth cleaning of the primary exchanger or if this latter is replaced. To
checkthestatusofthetotalhourmeter,multiplythereadingby100(e.g.
readingof18=1800totalhours;readingof1=100totalhours).
Theboilercontinuestooperatenormallyevenwhenthealarmisactivated.

4.5 Setting the thermoregulation (graphs 1-2-3)
The thermoregulation only operates with the external sensor connected;
onceinstalled,connecttheexternalsensor(accessoryavailableonrequest)
tothespecialterminalsprovidedontheboilerterminalboard(g.5).
ThisenablestheTHERMOREGULATIONfunction.
Selecting the compensation curve
The compensation curve for heating maintains a theoretical temperature of
20°Cindoors,whentheexternaltemperatureisbetween+20°Cand-20°C.
Thechoiceofthecurvedependsontheminimumexternaltemperatureen-
visaged(andthereforeonthegeographicallocation),andonthedelivery
temperatureenvisaged(andthereforeonthetypeofsystem).Itiscarefully
calculatedbytheinstalleronthebasisofthefollowingformula:
envisageddeliveryT.-Tshift
KT=
20-min.envisagedexternalT.
Tshift = 30°C standard installations
 25°Coorinstallations
Ifthecalculationproducesanintermediatevaluebetweentwocurves,you
areadvisedtochoosethecompensationcurvenearestthevalueobtained.
Example:ifthevalueobtainedfromthecalculationis13,thisisbetween
curve10andcurve15.Choosethenearestcurve,i.e.15.
Selectthe KTusing trimmerP3 on the board(see multiwirewiringdia-
gram).
To access P3:
- remove the housing,
- loosenthexingscrewontheinstrumentpanel
- turntheinstrumentpaneltowardsyou
- loosenthexingscrewsontheterminalboardcover
- unhooktheboardcasing
Live electrical parts (230 V AC).
TheKTvalueswhichcanbesetareasfollows:
standard installation: 10-15-20-25-30
oorinstallation2-4-6-8
andthesearedisplayedforapproximately3secondsafterrotationofthe
