Page 8: General Description
GENERAL DESCRIPTION The two models - EOG621B and EOG621W - differ only as regards their styling (colours). Both models are designed for the following types of cooking: - Normal gas cooking. - Electric grill cooking. - Electric grill plus spit cooking. -
Page 9: Spark Plug / Flame Detector Gaps
SPARK PLUG / FLAME DETECTOR GAPS In order to assure that the system functions correctly, the ignition spark plug and flame detector must be correctly positioned. The ignition spark plug/flame detector is secured by a rigid bracket in a precisely-determined position. If the spark plug is bent or incorrectly positioned, this will alter the gap and may result in incorrect operation. -

Page 11: Solenoid Valve
SOLENOID VALVE The solenoid valve which controls the flow of gas to the burner is powered by direct current and actioned by the electronic control unit. If the gas supply should be interrupted (the gas solenoid valve does not open), check that the electronic control unit supplies the correct voltage to the solenoid valve. -
Page 12: Control Circuit And Control Unit
CONTROL CIRCUIT AND CONTROL UNIT The control circuit for the burner consists of an electronic control unit which is actioned by the oven thermostat and the function selector knob. The electronic control unit controls the flow of gas by means of the solenoid valve positioned at the gas intake. -

Page 14: Safety Thermostat
SAFETY THERMOSTAT The entire electrical circuit of the oven is protected against overheating by a normally-closed ceramic thermostat (see fig. 15) which opens at a temperature of 270°C in the centre of the oven. The main cause for intervention of the safety thermostat is generally a malfunction of the tangential fan; however, the thermostat may also intervene if the appliance is not correctly built in. -
