Thesystemisnotintendedforuseby
persons(includingchildren)withreduced
physical,sensoryormentalcapabilies,orlack
ofexperienceand/orknowledge,unlessthey
havebeengiveninstruconoraresupervised.
Theterm“specieduse”alsocovers
observanceoftheoperang,andinstallaon
andserviceinstrucons(suppliedseparately).
TheAlde3020CompactHEmustbe
installedorrepairedbyacompetentpersonin
accordancewithcurrentlocalregulaons.
Intheunlikelyeventthatyoursystem
developsafault,switchothesystemand
contactAlde,oryourdealerorinstaller.
The owner is always responsible for
maintenance and arranging inspecon.
1.3 System Design
Theboiler’sinternalheatexchangerconsists
ofthreeconcentriccylinders;thecombuson
chamber,thecentralheangcylinderandthe
hotwatercylinder.
Thecombusonchamberismadefrom
aluminium,andisdividedintotwohalvesby
abaeplate,withtheburnerheadlocated
inthetophalf,andtheuegasesvenng
throughtheboomhalf.
Thecombusonassemblyisxedtothe
endoftheinternalheatexchanger.Itconsists
oftheburner,combusonfan,gasvalve,air
intakeandexhaustducts,andgasline.
Twoelectricheangelementsaresealed
insidethecentralheangcylinder,onefor
1kW,onefor2kW.
Theroomthermostatisintegratedinto
thetouchscreencontrolpanelandconnected
totheboilerbyaRegisteredJack(RJ)cable.

2. DESCRIPTION OF FUNCTIONS
2.1 Gas Heang
Whengasheangissettoon,thecombuson
fanstartstorevolve.Oncethecorrectspeed
isachieved(inrpm),asignalissenttothePCB
fortheburnertobelit.Thegasvalveopens,
passinggas,andtheignionmoduleonthe
PCBgeneratessparksattheelectrodeonthe
burnerhead.
Whentheburnerignites,aame
supervisiondevicesignalstheignionmodule
toceasesparking.Theburnerresunlthe
boilerorroomthermostatreachthesetpoint.
Shouldtheburnerameoutunexpectedly,
theFSDdetectsthisandaemptstoreignite
(forabout10seconds),beforeshungdown
andraisingafaultcode.
2.2 Electric Heang
Whenelectricheangissetto1,2or3kW,
relaysonthePCBtrip,feedingthe230V
supplytotheelectricheangelements.These
arecontrolledbythesameprogrammeasthe
gasheang.
2.3 Domesc Hot Water
Thecombi-typeboilerautomacallyproduces
hotwater.Heatisemiedfromthecentral
heangcylinderintothehotwatercylinder.
Ifthehotwatercylinderisempty,theairis
heatedbutnodamagecanresult.
TIP!
Listencarefullytotheignion
sequenceoftheboiler.You
shouldhearthewhirlofthe
combusonfan,theclunkofthe
gasvalveandtheck-ckofthe
ignionmodule.
TIP!
Inagoodsummer,forexample,
lowerthedesiredtemperature
onthecontrolpaneltoaround
10°C.Thecentralheang
willnotcirculate(unlessthe

3. DOMESTIC HOT WATER
Beingacombi-typeboiler,theAlde3020
CompactHEhasanintegrated,stainless
steelhotwatercylinderthatholds
approximately8.4litresoffreshwater.
Theboilercanproducearound12
litresof40°Cwarmwaterper30mins(at
acoldwatertemperatureof10°C).Ifonly
theelectricheangisused,thiscapacityis
slightlyreduced.
Onlyusepotablefreshwater.Grey
water,desalinatedwater,orwaterotherwise
unttodrinkisnotsuitableforuseas
domeschotwater.
Alwaysushoutthehotwatercylinder
beforeuse,especiallywhenithasstood
emptyforsomeme.
Targethotwatertemperatureisgreater
than50°Cinnormaloperaon,toprevent
thegrowthofLegionella.Over50°C,the
hotwaterwillbeheatedtothemaximum
achievabletemperatureattheme.This
allowsthehotwatertoachievedisinfecon
temperatures,andincreaseswarmwater
performance.
Ifscaldinghotwatertemperaturesarea
concern–suchaswiththeyoung,elderlyor
inrm–thermostacmixingvalves(TMVs)
canbeed,andmayberequiredbylocal
regulaons.
Avoidsteriliserproductscontaining
sodiumhyperchlorite,forexample,asthese
willcauseseverecorrosiondamagetothe
hotwatercylinder,andisnotcoveredunder
warranty.Readtheproductlabelorcontact
theproductmanufacturerfordetails.
Whenthehotwatercylinderisin
connuoususe,itshouldbedrainedand
relledonceamonth.Thisrecreatesthe
aircushioninthehotwatercylinderthat
absorbspressuresurges.
IMPORTANT!
Anysteriliserproductsshouldbe
suitableforusewithstainlesssteel.
IMPORTANT!
Alwaysdraindownandcompletely
emptythehotwatercylinder
whenthereisriskoffrost,unless
thevehicleisexplicitlystatedto
beself-winterisingbythevehicle
manufacturer.

4.1 Filling
ThecentralheangsystemislledwithHTF
throughtheexpansiontank,eitherbyhand,or
usingtheAldeservicepump.Anycontainers

5.5 Liqueed Petroleum Gas
LPG(liqueedpetroleumgas)hastwomain
variants,propaneandbutanegas.Thegas
heanginyourAlde3020Compactboilercan
usepropaneorbutanegasasfuel.ManyLPG
fuelscontainamixtureofpropane,butaneand
otheraddives.
BS5482Part1states,“For butane
cylinders, sasfactory service might not be
obtained at temperatures of less than 10 °C;
the most suitable temperature range is from
13 to 30 °C. For temperatures less than 13 °C,
the use of propane should be considered.”
Forthisreason,Alderecommendsusing
propanegasforallyearroundgasheang.
LPGcylinderscontainbothgasand
liquidforms.Whenthecylinderislled,high
pressuretransformsthegasintoliquid.The
liquidrevertstogaswhenthevalveonthe
