cooking technology. The baking process is so fast that food retains its natural juices. Bread products
brown and become crisp while vegetables retain their color and texture.
Flash
Bake ovens use visible and infrared light energy to cook by radiative heat transfer. The infrared
energy browns the surface of the food, while the visible light energy penetrates and heats it internally.
Using the proper combination of visible and infrared light energy, the

LOCATION
When deciding oven placement, be sure to consider clearance and available air for oven cooling. If the
inlet air is obstructed or heated, the oven will not operate properly.
Install the oven on a level countertop.
There must be a 3" (76 mm) minimum clearance on each side of the oven. The area behind the oven
around the blower must be kept clear of obstructions and allow free air circulation.
