Operating instructions

Making the Electrical Connections
Push in the tabs (P fig. 11) on either side of the boiler and pivot the
electrical box forward to gain access to the electrical connections.
Undo the two retaining screws (A fig. 1 l), remove cover (B fig. 11)
and remove cable clamp.
Connect the live and neutral wires to the multipin plug leaving
sufficient earth wire to connect to the earthing point. (B fig. 12)
Note: The connections should be made so that should the lead be
pulled from its anchorage, the current carrying wires become taut
before the earth wire.
If using a room thermostat or other external control, they can be
connected in place of the link on the multipin plug. (fig. 12).C
Note: Use only controls designed for voltage free switching or 24V
supply. Do not connect to a 230V supply.
Connect multipin plug into the socket on the pcb (D fig. 12)
attached to the cover (B fig. 11). Secure the cable using the cable
clamp and replace the cover.
NB Any changes to the factory settings on the pcb can be
made before replacing the electrical box cover (see electrical
adjustments pages 20 and 21).
