10.7Making The Electrical Connections

WARNING: This boiler must be earthed

IMPORTANT: Four core cable is required to supply the boiler as a permanent live is necessary for the operation of the condensate pump and frost protection.

1.The electrical connections are on the right hand side of the boiler. Depending upon the nature of the installation it may be preferable to wire up to the boiler first before manoeuvering into position.

2.Undo the two screws securing the cable clamp and place to one side (Fig. 31).

3.Route the incoming electrical cable(s) from the system control wiring centre through the grommet in rear of the boiler and the grommet in the support bracket. This will prevent damage to the cable(s).

4.Lay the cable through the cable clamp to gauge the length of wire required when it is connected to the 4-way terminal block.

5.Connect the (S/L), ( ), (N) and (P/L) wires to the

4-way terminal block (Fig. 33) and refit the cable clamp (Fig. 31).

INTEGRAL PROGRAMMER

If the optional integral programmer is being fitted it can be done at this stage. Consult the instructions supplied in the programmer kit.

Check the electrical installation for;

earth continuity, short circuits, resistance to earth, correct polarity and fuse rating.
