15.0Changing Components

The removal of the fan is necessary to enable the changing of the injector pipe, condensate trap and gas valve (see section 13.6).

15.9Injector Pipe (Fig. 53)

1.Remove the injector pipe by pulling out from the ‘O’ ring joint in the gas valve.

2.Fit the new injector pipe and reassemble in reverse order.

15.10Gas Valve (Fig. 53)

IMPORTANT: After replacing the valve the CO2 must be checked as detailed in Section 14.1.4 to 14.1.6. Only change the valve if a suitable calibrated combustion analyser is available, operated by a competent person - see Section 14.1.3.

1.Isolate gas supply and disconnect the gas tap by removing the four screws.

2.If required remove the condensate pump to increase access (see Section 13.4) and undo the case pressure pipe from the valve.

3.Disconnect the electrical plug from the gas valve.

4.Remove the fan (see Section 13.6) and injector pipe.

5.Remove the two gas valve securing screws from inside the air box holding the gas valve, and remove the valve.

6.Remove the aluminium spacer and its gasket from the gas valve.

7.Fit the aluminium spacer and its gasket to the new valve.

8.Fit the new gas valve and reassemble in reverse order.

NOTE: Check for gas tightness after replacing gas valve.

9.Check the CO2 level. If the level is greater than that quoted, telephone the Technical Enquiries for further advice.

15.11Condensate Trap (Fig. 54)

1.Disconnect the condensate trap from the base of the heat exchanger.

2.Disconnect the condensate drain ‘O’ ring connection from the condensate trap and condensate pump. For ease of access also remove the pump.

3.Undo the condensate trap lock nut.

4.Remove the condensate trap from the boiler.

5.Disconnect the sensor leads.

6.Fit the new condensate trap and reassemble in reverse order. When refitting the pipe from the trap to the pump ensure that all seals and connections are made.

7.Prime the condensate trap (fill first chamber), check for leaks (see Section 8.5).
