Electrical connections

1.9.1 Mains connection
A mains supply of 230 V - 50Hz is required.
External controls are suitable for volt free or 230 V installation.
Wiring to the boiler MUST be in accordance with the current
I.E.E. (BS.7671) Wiring Regulations and any local regulations.
Wiring should be a 3 core PVC insulated cable, not less than
2
0.75 mm (24 x 0.2 mm), and to BS.6500 Table 16.
Connection must be made in a way that allows complete
isolation of the electrical supply such as a double pole switch
having 3 mm (1/8'') contact separation in both poles, or a plug
and socket, serving only the boiler and system controls. This
boiler is equipped with a double pole switch see fig. 17, item 1.
The means of isolation must be accessible to the user after
installation.
The electrical connection to the mains supply should be readily
accessible and adjacent to the boiler.
If the supply cord is damaged, it must be replaced by a
registered Corgi installer to avoid a hazard.
The electrical supply for both the boiler and the system must
be taken from the same sparred fused spur outlet.
Subject to modifications resulting from technical improvements!
