10. CHECKING THE OVEN
1. Turn the oven thermostat to Mk.9 and check that there is sparking from the ignition system. This should
continue until the oven burner is alight.
2.. When 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.) by pass rate.
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 thermostat to Mk.2, close the oven door and check that after about 10 minutes the flame
has reduced in size.
6. Turn off the thermostat and check that the oven flames go out.
