Electrical Supply
Wiring external to the appliance MUST be in accordance with the current I.E.E. Regulations for Electrical Installations, and
any Local Regulations which apply. The combination boiler is supplied for 230 Volts ~ 50 Hz, Single Phase. To protect the
appliance it is essential that the electrical supply is fused at 3 A rating.
THIS APPLIANCE MUST BE EARTHED The method of connection to the mains electricity supply must provide means of
completely isolating the electrical supply to the combination boiler and its ancillary controls. The appliance is designed to be
the wiring centre for the installation, therefore no additional live supplies are required from either timers or room thermostats.
Isolation is preferably by the use of a fused three-pin plug and unswitched shuttered socket-outlet, both complying with the
requirements of BS 1363. OR a 3 A fused double-pole switch, having a 3mm contact separation on both poles can be used.
It is important that the point of connection to the mains should be readily accessible and adjacent to the combination boiler.
