5.11 Electrical Connection

1. The appliance requires an electrical supply from the
heating controls system.
2. A permanent live supply is required for Deluxe Model
Firefronts.
WARNING: The appliance must be earthed. The input
cable for the appliance should be 0.75mm
227 (heat resistant). The system external controls and
the appliance must be supplied by the same isolator.

5.12 Making the Electrical Connection

1. Undo the two screws holding the electrical plug, socket
and heat shield to the left hand side of the base tray (Fig.
20).
2. Disengage the lugs on the socket from their slots (Fig.
21). Pull the mains input plug from the inlet socket (Fig. 22).
3. Remove the screw and cover from the socket (Fig. 23).
4. Remove the rear cable grip and connect the supply cable
(Fig. 24) as follows:
•
Control system switched live to L1
•
Control system neutral to N
•
Earth to the terminal screw adjacent to the
input plug
5. For Deluxe firefronts connect the permanent live supply
L2 (Fig. 24a). Remove the side cable clamp and connect the
wire from the firefront kit as indicated
•
Brown (live) to L2
•
Blue (neutral) to N
•
Green & Yellow (earth) to the terminal screw
adjacent to the input plug.
6. The earth wire(s) should be sufficiently long that if the
supply cable is pulled the live and neutral wires become taut
before the earth.
7. Replace the cable grip(s), ensuring the outer insulation is
firmly held and replace the socket cover and screw.
8. Refit the socket to the plug and re-engage the tugs in the
base tray. Resecure with the two screws, locating the heat
shield with the forward screw.
9. Ensure that all cables are routed away from the boiler
casing and hood, making use of the clips on the front edge
of the boiler base tray as required.
