6.0SystemDetails
6.1WaterCirculatingSystems
1.Theapplianceissuitableforusewithopenventfullypumpedsystemsandsealedsystems.
Thefollowingconditionsshouldbeobservedonallsystems:
Thestaticheadmustnotexceed30m(100ft)ofwater.
Theboilermustnotbeusedwithadirectcylinder.
Draincocksshouldbefittedtoallsystemlowpoints.
Allgasandwaterpipesandelectricalwiringmustbeinstalledinawaywhichwouldnotrestricttheservicingoftheboiler.
Positionisolatingvalvesasclosetocirculatingpumpaspossible.
Itisrecommendedthatthereturnpipeisfittedwithanautomaticairventasclosetotheboilerasispractical.
6.2TreatmentofWaterCirculatingSystems
Allrecirculatorywatersystemswillbesubjecttocorrosionunlessanappropriatewatertreatmentisapplied.Thismeansthatthe

boilernoiseandcirculationproblems.
Whenfittingnewsystemsfluxwillbeevidentwithinthesystem,whichcanleadtodamageofsystemcomponents.
