Making the electrical connections

To gain access to the electrical connections, press tabs

(P Fig 12) to release the catches on either side of the

boiler and pivot the electrical box forward.

Remove the two retaining screws (Afig 12), lift the cover

and turn over to reveal an interface PCB and connecting

block (Fig 13).

Connect the live and neutral wires to the connector (D

Fig 13) on the interface PCB leaving sufficient earth wire

to connect to the main earthing point.

The connecting cable for the cylinder thermostat is coiled

behind the temperature adjuster on the cylinder. This

cable is led through the cable clamp on the boiler

electrical box and is connected to connecting block (D)

as shown in Fig 13.

If a room thermostat is to be fitted, the link wire on the

main connector plug (C Fig 13) must be removed and

the room thermostat connected in its place.

These

connections are for use with voltage free switching.
