14Hints and tips• Arrange the shelves in the requiredpositions before switching the oven on.Shelf positions are numbered from thetop downwards.• Ensure that food is placed centrally onthe shelf and there is sufficient roomaround the baking tray/dish to allow formaximum circulation.• Do not push dishes too far back as foodwill burn if it overhangs the burnerflame.• Stand dishes on a suitably sized bakingtray on the shelf to prevent spillage ontothe oven base and to help reducecleaning.• The material and finish of the bakingtray and dishes used affect basebrowning. Enamelware, dark, heavy ornon-stick utensils increase basebrowning. Shiny aluminium or polishedsteel trays reflect the heat away andgive less base browning.• When cooking more than one dish inthe oven, place dishes centrally ondifferent shelves rather than clusterseveral dishes on one shelf, this willallow the heat to circulate freely for thebest cooking results.• If you are cooking more than one tray ofsimilar items, for example cakes orbiscuits, swap the trays during cookingor you can remove the top tray whenthe food is cooked and move the lowertray to the higher shelf to finish cooking.• Do not place baking trays directly onthe oven base as it interferes with theoven air circulation and can lead tobase burning; use the lower shelfposition.Do not place cookware and cookingpots with rough bases e.g. cast ironon the oven door as damage to theglass may occur.
