6.1 Control Box Cable Connection

Warning. This boiler must be earthed.

Remove the screw and cover from the mains inlet connector,
supplied loose, see diagram 6.1.

Using heat resistant flexible cable of suitable length and rating
as in Section 1.6, connect the three cables to the required
terminals in the connector. Secure the outer sheathing with the
cable clamp.

Engage slots and lugs, replace cover and secure with screw.

Connect the mains inlet connector to the control box and use
three of the cable clips, supplied loose, pushed on to the edge
of the left hand panel in positions “CB” as shown in diagram 6.2
to make sure the cable does not make contact with any hot
surfaces.

6.2 Pump Cable Connection

Heat resistant cable with a rating as stated in Section 1.6 must
be used for all wiring near the boiler, including the pump if within
the boiler casing.

Support pump cable away from hot surfaces if within the boiler
casing by pushing two cable clips, supplied loose, on to the top
edge of one side panel, shown as “P” or “AP” in diagram 6.2.

6.3 System Controls

The electrical installation must be made according to the
current issue of BS7671.

The electrical isolator must isolate both the boiler and any
system controls.

6.4 Testing

Checks to ensure electrical safety should be carried out by a
competent person.

In the event of an electrical fault after installation of the boiler,
preliminary system checks must be carried out, that is, earth
continuity, polarity and resistance to earth, as described in the
British Gas Multimeter Instruction Book or similar publication.
