PRESSURE TESTING
1.The oven injector is used as a pressure test point.
Remove the oven furniture. Remove oven burner box retaining clips (one spring clip from each side) and remove box front cover. Replace one clip back into the right hand side of the burner box. Remove oven burner by removing the spring clip from the right hand side of the oven burner and slide burner off injector, whilst easing it forward and taking care not to strain the F.S.D. phial.
2.Connect the pressure gauge to the oven injector.
3.Check the supply pressure by turning the thermostat on and one hotplate tap full on and light the appropriate burner. The pressure should be either:-
(i)For Natural Gas 20mbar
(ii)For LP. Gas. The pressure must be set to 28 mbar for use on butane or 37 mbar for use on propane.
4.Turn off the taps, disconnect the pressure gauge and replace oven burner and cover, ensuring that the F.S.D phial is correctly located into the bracket on the burner.
5.Check operation of the oven.
CHECKING THE GRILL
Place the grill pan containing the grid, with the handle attached, into the grill compartment. Light the grill burner by turning the grill tap full on and pressing the ignition button on the fascia panel. As soon as the burner is lit the button can be released.
CHECKING THE HOTPLATE
Lift the lid. Fit the burner crowns and caps ensuring that they are correctly seated. Fit the pan supports. Check each of the hotplate burners in turn by turning the hotplate tap to its full on position and pressing the ignition button. As soon as the burners are lit the button can be released.
CHECKING LID SHUT-OFF DEVICE
1.Lift the lid
2.Turn one hotplate tap to its full on position and push the ignition button.
3.Close the lid. There should now be no gas supply to the hotplate and the burner will go out.
4.Turn off the hotplate and lift the lid. The gas supply should now be restored to the hotplate, when the tap is turned on.
CHECKING THE SECOND OVEN
1.Turn the second oven thermostat control knob anticlockwise to Mk.8 and press the ignition button. As soon as the burner is alight the button can be released.
2.When the oven burner lights up there should be a low gas rate at first to the oven burner which is the F.S.D.
3.When the F.S.D. phial has heated up it opens the F.S.D. valve and the main gas stream flows to the burner.
4.After 1 minute check that the flame covers the full width of the burner and is stable.
5.Set the oven control to Mk. 2, close the oven door and check that after about 10 minutes the flame size has reduced.
6.Turn off the control knob and check that the oven flames go out.
CHECKING THE MAIN OVEN
1.Turn on the oven thermostat control knob to mark 9 and press the ignition button. As soon as the burner is alight the button can be released.
2.There should now be a low gas rate to the burner, which is the F.S.D by pass rate.
3.When the F.S.D. phial has heated up it opens the F.S.D valve which allows the main gas supply to the oven burner.
4.After 1 minute check that the flame covers the full width of the burner and is stable.
5.Set the oven control to Mk 2, close the oven door and check that after about 10 minutes the flame size has reduced.
6.Turn off the control and check that the oven flames go out.
