8. CHECKING THE MAIN OVEN
1Turn the main thermostat knob to Mk. 9 and check that there is sparking from the ignition system. This should continue until the oven burner is alight.
2When the oven burner lights up the sparking should cease. There should be a low gas rate at first to the oven burner which is the flame supervision device (F.S.D.)
3When the F.S.D. phial has heated up it opens the F.S.D. valve and the main gas stream flows to the burner.
4After 1 minute check that the flame covers the full width of the burner and is stable.
5Set the oven thermostat to Mk. 2, close the oven door and check that after 10 minutes the flame size has reduced.
6Turn off the thermostat and check that the oven flames go out.
