IT IS THEN IMPORTANT TO CLOSE THE LIGHTING
PORT COVER and replace the burner access door, ensuring
it is correctly located and sealed.
3.2 Immediately after lighting, turn the oil control valve knob to
setting 1, see Diagram 1.
3.3 After about 30 minutes, increase the oil flow rate by turning
the oil control knob to setting 4. To reduce heat-up time,
turn to setting 6 for approximately 3 hours and then turn
down to the recommended setting.
3.4 After 1 hour, check that the burner is glowing red showing
it is running correctly. If there are yellow/orange flames
present, then turn the cooker off and call an approved
engineer.
4. COOKER TEMPERATURE CONTROL
4.1 The temperature control knob is found on the top of the oil
control valve. Turning the control knob anti clockwise will
increase the cooker temperature, Diagram 1.
4.2 Heat to the cooker can be reduced by turning the control
knob down or increased by turning up from the
recommended setting. The recommended setting is 3 for a
Two-Oven and 4 for a Four-Oven model. However, if
adjusted it will take 3 to 4 hours to stabilise temperature
due to the thermal mass of the cooker.
4.3 The temperature indicator is located above the top oven
door and has three sections: black, silver and red.
4.4 After approximately 8 hours the cooker should have
reached it's optimum operating temperature. The column of
mercury should be approximately mid way between the red
and black areas on the temperature gauge. This will indicate
that the cooker has been saturated with heat. To achieve an
accurate temperature value, this can be accomplished by
employing an oven thermometer and recording the reading
as a datum in relation to the position of the column of
mercury.

Frost Protection (DHW version only):
5.1 If the DHW boiler is to be out of use for a long period of
time during severe weather conditions, it is recommended
that the whole system be drained down to avoid the risk of
freezing. Frequent draining, especially in hard water areas,
should be avoided as this may lead to scale build up inside
the boiler.
5.2 For short periods of absence, leave the cooker operating at
a low thermostat setting.
