Using the Oven – cont’d
6. To turn off: Turn the control knob until the dot on the control knob is aligned with the
dot on the control panel.
7. Flame Failure Device (FFD): The oven burner is fitted with a flame sensing probe
which will automatically cut off the gas supply in the event of the flame going out.
8. Oven shelves: The oven shelf has been designed to allow good circulation at the rear
of the oven and are also fitted with a raised bar to prevent trays or dishes making
contact with the back of the oven. To remove a shelf, pull forward until it stops, raise at
the front and remove.
Temperature Control
The temperature in the oven is controlled by a thermostatic gas tap and is variable over
the range 130 ºC to 240ºC. Approximate temperatures for the settings on the control knob
are shown in the table below. The temperatures indicated refer to the centre of the oven,
and at any particular setting the oven will be hotter at the top and cooler towards the base.
The variation between top to centre, and centre to bottom is approximately equivalent to
one Gas Mark. Good use can be made of the temperature variation in that several dishes
requiring different temperatures may be cooked at the same time. In this way maximum
benefit can be obtained from the gas used to heat the oven. Care should be taken not to
overload the oven; allow adequate spacing for free circulation of heat.
