Diagram 9. 3 21 221873B 7100 10 Commissioning Please ensure the "Benchmark" logbook is completed and left with the user. Check the operation of the safety valve by turning the safety valve knob in the direction of the arrow. Lower the pressure to the initial cold fill design pressure, refer to Table 1. Position the set pointer on the boiler pressure gauge at this pressure also. Refit inner case front. 10. 1 Filling Domestic Water Circuit Check that the boiler is isolated from the electrical supply, at the external isolator. Fully open the domestic water supply stop cock or valve in the supply to the boiler. Open the inlet domestic water isolation valve, lever in line with the valve body, see diagram 6. 1. Check for water soundness of the whole domestic water system and boiler. 10. 3 Preparation for Lighting Isolate the boiler from the mains electrical supply at the external isolator. Turn on the gas service cock, slot in line with the length of the cock. Loosen the burner pressure test point screw and connect a suitable pressure gauge, see diagram 10. 1. 10. 2 Filling the Heating System Open the two central heating isolating valves, levers in line with the valve body, see diagram 6. 1. Flush, fill and vent the system refer to Section 4. 8 "Filling Sealed Systems". SEVERAL COMPONENTS OPERATE ON MAINS VOLTAGE AND WITH THE OUTER CASE REMOVED, LIVE COMPONENTS BECOME EXPOSED. Operate button "J" between "L" summer and "K" winter to ensure that water flows through all parts of the boiler and air is not trapped in the boiler internal bypass. 10. 4 Burner Pressure - Hot Water Connect the electrical supply; the pump will operate for about 30 seconds, then the pump will stop. [. . . ] Remove the plate to plate heat exchanger, refer to Section 14. 23. 14. 24 Expansion Vessel Before starting refer to Section 11. Renewal of the expansion vessel requires the boiler to be removed from the wall. As an alternative, a separate expansion vessel of the same specification may be connected as close as possible to the boiler, leaving the original in position, refer to the Installation Instructions. Disconnect the boiler water connection union nuts at the front of the isolating valves, see 6. 1.
