When you have made the adjustment, touch the START pad to go back to the time of day display. Use your oven as you would normally. – 12 – Using the Convection Oven Convection Fan Operation In a convection oven, a fan circulates hot air over, under, and around the food. This circulating hot air is evenly distributed throughout the oven. As a result, foods are evenly cooked and browned ― often in less time than with convection heat. Note: To maximize cooking evenness, the fan is designed to rotate in both directions, with a pause in between. This is normal. The convection fan shuts off when the oven door is opened. DO NOT leave the door open for long periods of time while using convection cooking or you may shorten the life of the convection heating element. _________________________________________________________________________________________ Introduction The convection oven comes with two convection baking modes: Multi and 1 Rack: MULTI ― for convection cooking on more than one rack. Touch the CONVECTION BAKE pad and then the 2 pad. See the Multi-Rack Convection Baking section below. 1 RACK ― for convection cooking on one rack only. Touch the CONVECTION BAKE pad and then the 1 pad. See the 1 Rack Convection Baking section below. _________________________________________________________________________________________ Multi-Rack Convection Baking Because heated air is circulated evenly throughout the oven, foods can be baked with excellent results using multiple racks. Multi-rack baking may increase cook times slightly for some foods, but the overall result is time saved. Cookies, muffins, biscuits, and other quickbreads give very good results with multi-rack baking. To cook food on more than one rack in convection bake, use CONVECTION BAKE MULTI. For multi-rack baking, place the flat rack in the highest (C) position and the offset rack in the middle (B) position. _________________________________________________________________________________________ 1 Rack Convection Baking When convection baking with only 1 rack, use CONVECTION BAKE 1 RACK and follow the rack positions recommended in the Using the Oven section of the Owner's Manual. Note: Ideal for baked foods cooked on 1 rack. – 13 – (Continued next page) How to Set the Lower Oven for Convection Baking or Roasting OR 1.
