The boiler requires a permanent mains supply through an external isolator which must also isolate any heating system controls, see diagram 9. 2. Any heating system controls must not interrupt the permanent mains supply to the boiler, as this would prevent frost protection from operating. Using PVC cable of a suitable length and rating as stated in Section 1. 8 "Electrical Supply", route the mains supply cable and connect to the appropriate terminals of the connector block, restrain with the cable clamp supplied, see diagram 9. 2. Standard colours are, Brown - Live, Blue - Neutral, Green and Yellow - Earth. Make the earth cable of a greater length so that if the cable is strained the earth would be the last to become disconnected. CAUTION: It is ESSENTIAL to make sure that the polarity is correct. 9. 4 Frost Thermostat If the installation requires protection by a "frost thermostat", connect a single pole type, to the appropriate terminals of the connector. Keep all cables away from hot surfaces. 9. 5 Electrical Test Carry out preliminary electrical system checks as below: 1. Refit the control fascia. 9. 2 Heating System Controls All external controls and wiring are required to provide a minimum of reinforced insulation at 250Vrms between the parts of those devices operating at mains hazardous voltage and the user accessible parts at those devices. Note: For further information, see The Building Regulations 1991 - Conservation of fuel and power, 1995 edition - Appendix G, table 4b. If electrical controls are not to be used to regulate the heating system, fit a link cable between LP and LS on the mains supply connection block, see diagram 9. 2 for positional reference. When any form of external electrical control is being used to regulate the system, connect the external system controls to L. s. on the connection block on the mains terminal block bracket, see diagram 9. 2. 9. 3 Programmer Kit (if applicable) Open the controls cover door. Remove the programmer cover and blanking plate, see diagrams 9. 1 and 10. 2. Fit the programmer bracket with the two screws supplied, see diagram 9. 2. Connect the wires to the connection block and programmer, see diagrams 9. 2 and 14. 24. Connect the programmer plug, see diagram 13. 4.

Please ensure the "Benchmark" logbook is completed and left with the user. Adjust the pressure if required by removing the screw cap and turning the maximum rate adjustment screw on the gas control valve, see diagram 10. 1. 10. 1 System Commissioning Check that the boiler is isolated from the electrical supply, at the external isolator. Fully open the two water isolating valves, levers in line with the length of the valves, see diagram 6. 1. [. . . ] Carefully lay the boiler down on its side for access to the expansion vessel. Disconnect the union nut connection, see diagram 14. 18 and discard the sealing washer for the new one supplied. Connect the union nut, when fitting the expansion vessel, before clamping it. Refer to Sections 8, 9 and 10 when mounting the boiler. 14. 20 Automatic Air Vent Before starting refer to Section 11. [. . . ]
