The mains electrical supply must be taken from a double pole isolating switch with a 5amp
fuse, positioned somewhere close to the boiler. Heat resisting cable must be used which can be
routed into the boiler through the access provided on either side of the base.
Ancillary controls may be provided for with terminal connections in the control panel.
