3.Open the mains water supply to the boiler.

4.Open all hot water taps to purge the DHW system.

5.Ensure that the filling loop is connected and open, then open the heating flow and return valves on the boiler.

6.Open the screw on the automatic air vent on the pump body (Fig. 59).

IMPORTANT: If the boiler is installed at a high point in the system it is strongly recommended that Automatic Air Vent Kit 720004701 is fitted. Ensure that this vent is open.

7.The system must be flushed in accordance with BS 7593 (see Section 6.2) and the flushing agent manufacturers instructions.

8.Pressurise the system to 1.5 bar (Fig. 60) then close and disconnect the filling loop.

9.Turn the gas supply on and purge according to in GB BS 6891 and in IE I.S. 813 “Domestic Gas Installations”.

10.Test for gas tightness.

11.Hinge the facia panel upwards and refit the case front panel. Tighten the securing screws.

IMPORTANT: The combustion for this appliance has been checked, adjusted and preset at the factory for operation on the gas type specified on the appliance data plate. No measurement of the combustion is necessary. Do not adjust the air/gas ratio valve.

12. Having checked:

•That the boiler has been installed in accordance with these instructions.

•The integrity of the flue system and the flue seals.
