13. CHECKING THE SECOND OVEN
1. Turn the second oven thermostat control knob anticlockwise to Mk8 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. 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 control to Mk. 2, close the oven door and check that after approx. 10 minutes the flame
size has reduced.
6. Turn off the control knob and check that the oven flames go out.
14. CHECKING THE MAIN OVEN LIGHT
Turn the main oven thermostat knob full on and check that the main oven light is operative. Turn off the
thermostat.
