This is due to the high
efciency and hence low ue
gas temperature of the boiler.
It is normal and not a fault

Incaseoftheriskoffrost:
• Makesurethattheelectricalandgas
supplytotheapplianceisturnedon.
• Thefrost-protectionsystemstarts
theappliance’spumpwhenthe
temperatureintheheatingcircuitgoes
below12°C.Thepumpstopswhenthe
temperatureofthewaterintheheating
circuitreaches15°C.Ifthetemperature
intheheatingcircuitgoesbelow7°C,
theburnerislituntilthetemperature
reaches35°C.
Iftheboilerisin«DomesticHotWater»
modeonly,thefrost-protectionsystemis
alsoactive.
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.

bCAUTION: Your domestic
water circuit (hot and cold) is
not protected by the boiler.
10.3 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.
