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.

10.2 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

condensedrainexternaltothehouse.
• Releaseaniceblockagebytheuseof
warmclothsonthepipe.
Theboilershouldthenrestart.
