ELECTRICAL SUPPLY
The boiler and controls require 230V 1 phase 50Hz electric supply protected with a 5amp fuse.
THIS APPLIANCE MUST BE EARTHED.
A qualified electrician must carry out all electric wiring in accordance with current I.E.E Regulations and any local
regulations which may apply.
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.
