displayed,whichCANbecarriedoutby
theUSERtorestoreapplianceoperation
(Correctiveaction:...).Otherfaultcodes
MUSTbesolvedbyacompetentperson
only.
Like all condensing boilers
it will produce a plume of
condensation from the ue
terminal in cool weather.
This is due to the high
efciency and hence low ue
gas temperature of the boiler.
It is normal and not a fault
indication.
Ifanyfaultpersists,andyourappliancestill
does not work, leave it switched off and
contactyourcompetentperson.
9.1 Electrical Supply Failure
Theboilerwillnotworkwithoutan
electricalsupplyandnormaloperation

9.5 Protecting against frost
Appliance Protecion
Incaseoftheriskoffrost:
• Makesurethattheelectricalandgas
supplytotheapplianceisturnedon.
• Foranabsenceofseveraldays,you
canleavetheappliancetorunnormally.
Theappliancehasabuiltinfrost
protectiondevicethatprotectstheboiler
fromfreezing.Withthegasandelectric
suppliesONandirrespectiveofanyroom
thermostatsetting,thefrostprotection
devicewilloperatethepumpwhenthe
temperatureoftheboilerwaterfalls
below8OC.Atimerisusedsothatthe
temperaturecanbecheckedperiodically.
After10minutesthepumpwillbestopped
ifthetemperatureishigherthan10OCor
hasalreadyreached35OC.Theburner
willactivateiftheboilertemperature
doesnotreach10OCafter30minutesor
atanytimeifthetemperaturedropsto
5OC.Theburnerwillswitchoffwhenthe
temperaturereaches35OC.
Theappliancealwayshasfrostprotection
activewhenthepowerandgassupplyare
on.
System Protection
Theboileralonecannotensurethatthe
installationisprotectedagainstfrost.
NOTE:Anyotherexposedareasofthe
systemshouldbeprotectedbyaseparate
frostthermostat.
Incaseofprolongedabsence,where
powertothedwellingandtheboileris
switchedoff,contactyourInstallation/
ServicingcompanyorGlow-wormService
tohavetheinstallationdrainedortohave
theheatingcircuitprotectedbyaddingan
anti-freezespeciallydesignedforheating
systems.
CAUTION: Your domestic
water circuit (hot and cold) is
not protected by the boiler.
9.6 Condensate Drain Blockage
Asasafetyfeaturetheboilerwillstop
workingifthecondensatedrainbecomes
blocked.Duringfreezingconditionsthis
maybeduetotheformingoficeinthe
condensedrainexternaltothehouse.
• Releaseaniceblockagebytheuseof
warmclothsonthepipe.
Theboilershouldthenrestart.
• ContactyourInstallation/Servicing
companyorGlow-wormserviceifthe
faultpersists.
Disinfection Cycle
Thecylinderhasabuiltindisinfection
cyclewhichraisesthewatertemperature
to70oCfor1houreveryWednesdayat
2:00am.
9.7 Safety Discharge Valve
Thesafetydischargevalveanddischarge
pipeisttedtotheboiler.
• Ifthereisanydischargefromthepipe,
switchofftheboilerelectricalsupply,
thencallyourInstallation/Servicing
companyorGlow-wormservice.
