17AN OVENThe heating of the oven is achieved by turning the control knob clockwise to the required temperature asrecommended in the temperature charts. The pilot light will immediately come on and will automatically go offand on during cooking as the oven thermostat maintains the correct temperature.It should be noted that at the end of a cooking period there may be a momentary puff of steam when the ovendoor is opened, this will disperse in a few seconds and is a perfectly normal characteristic of an oven with agood seal.Since a fan oven heats up more quickly and generally cooks food at a lower temperature than a conventionaloven, pre-heating the oven is often unnecessary. However, foods such as bread, scones, Yorkshire pudding dooften benefit from being placed in a preheated oven.The charts on pages 20 and 21 are a guide only, giving approximate cooking temperatures and times. To suitpersonal taste and requirements, it may be necessary to increase or decrease temperatures by 10°C.Unless otherwise indicated in the charts, food is placed in a cold oven ie. without preheating.If food is placed in an already hot oven, the suggested cooking time should be reduced, depending on the typeand quantity of food being cooked.OVEN POSITIONSSince the distribution of heat in the fan oven is very even, most foods will cook satisfactorily on any shelfposition, but the shelves should be evenly spaced.To ensure even circulation do not use meat pans larger than 390 x 300mm (15ins x 12ins) and baking trays nolarger than 330 x 255mm (13ins x 10ins), these should be positioned centrally on the oven shelf.- Do not fit shelves upside down.- Never use more than 3 shelves in the oven as air circulation will be restricted.- $ood or cooking utensils should not be placed on the floor of the oven.To avoid unnecessary cleaning, rod shelves which are not in use should be removed from the oven.
