1.1 - Quick reference Guide
1. Itisrecommendedthattheboilerbeconnectedtoa10 hourorsimilaroff-peaktariffthatprovidessome
daytimeoff-peakhours.
2. Wheretheoff-peaktariffisrestrictedachangeoverrelayshouldbeusedtoswitchpowertotheboilerwhen
theoff-peaksupplyisnotavailable.
3. Fillthesystemwithwaterpriortoturningontheelectricalsupplytotheboiler.
4. Ensurethesystemisushedthoroughlybeforelettinganyair/waterexitthroughthepressurereliefvalve
(dirtcanpreventthevalveclosing).
5. Checkthesystemisfullbyturningthepressurereliefvalvecap,andcheckwaterexitscorrectlythrough
thedischargepipe.
6. Amanualpressuregaugeshouldbeusedtocheckthesystempressurewhencold.Thepressureshouldbe
setbetween1bar&1.5 bar.Noteallairshouldberemovedfromthesystembeforemeasuringthesystem
pressure.
6a Alternativewiththeelectricsupplyoff,theyellowbridgebetweenterminals10and11mayberemoved
beforellingthesystemforthenaltime(thispreventstheelementsturningon)andtheboilerpressure
gaugeusedtosetthecoldsystempressure.Oncesetto1-1.5bar,theboilershouldbeswitchedoffand
theyellowbridgereturnedtoitspositionbetweenterminals10&11.

1.2 - Install Options
1.SPACEHEATINGONLY(recommended)-directroomthermostatConnection
  •Theno-voltcontactsoftheroomthermostatshouldbeconnectedtoterminals1and2ofthe
boiler.
  • Menu option 4 should be set to 01 to allow the boiler to be controlled from the room

2. OPERATING WITH HOT WATER CYLINDER
Redringrecommendtouseadirectelectricunventedcylinderfortheproductionandstorageofthehotwater
asthisischeaperthananindirectcylinder,requireslessplumbing(pipingandvalves)andismorethermally
efcient.
Whenusingtheboilerforunventedhotwaterandheating,thetwo-portmotorisedvalveshouldbeinsertedin
theowfromtheboiler.ADifferentialPressurevalveshouldthenbeconnectedbetweentheowandreturnat
apointbetweentheboilerandthetwo-portmotorisedvalve.

Itisrecommendedthattheboilerbeusedforcentralheatingpurposesonlyandhotwaterbestoredandheated
byadirectelectrichotwatercylinder.Thisallowshotwatertobeheatedovernightonanoff-peaktariffand
reducesheatlossesbetweentheboilerandthecylinder.
2.1 - Introduction
TheRedringPowerstreamAscariboilerisanallelectricdomesticcentralheatingboilersuitableforuseona230V
52A50Hzsupply.Theunitiseasytoinstallandrequiresnoue,makingitidealforapartmentsorpropertiesin
conservation areas.
Theunitissuppliedreadyforoperationasa12kW230V(13kW 240V) singlephaseboilerandwillautomatically
modulate down to10,8and6kW.Themaximumoutputpowermayalsobemanuallylimitedtooperateat
maximum power levelsof10,8,6or4kWwiththeboilerproportionallymodulatingtolowerpowerlevels.
Finishedinacleanwhitecaseandwithdimensionsof620mmheightx405mmwidth,theboilerissuitablefor
installationinakitchenarea.Withthermalcutoutselectableat60oCor 100oCtheboilerissuitableforstandard
wetradiatorsystemsorunderoorheating.
Therearenospecific ventilationrequirementsassociatedwiththeoperationofthisboiler,howeverit is
recommended that the roomis dry and wellventilated.

WaterTreatment,CleansingandFlushingtheHeatingSystem
NOTE: British Standard BS7593: 1992 stresses the importance of cleansing and ushing of the system to
ensure it continues to run efciently with the minimum of maintenance necessary. Redring fully supports this
professional approach and recommendsthat the system is cleansed with an effective chemical cleanser and
protected long term with a suitable inhibitor. Such products are available from Fernox and Sentinal.
