Hints & Suggestions

Convection ovens constantly circulate air over and around the product. This strips away the thin layer of moisture and cool air from around the product allowing heat to penetrate more quickly.

Cooking times can be shortened and cooking temperatures can be reduced. To convert standard deck oven recipes, reduce the temperature 50°F and the time by 25%.

Make minor adjustments as necessary. The lower the oven temperature the more even the bake. Always weigh your product. This will give you a more consistent size, color and quality. Check the product near the end of the initial cooking cycle by turning on the oven light and

looking through the oven door windows. Do not open the oven doors during baking as this will change the baking characteristics of the

oven and make it difficult to determine a final program. If the product is overdone on the outside and underdone on the inside, reduce the baking

temperature. If the product is pulling away from the edge of the pan, the temperature is too high or the

cooking time too long. The convection is a mechanical piece of equipment. The same control settings will always

give the same results. If the results vary, problems may be because of product preparation.

UL File# MH19366

Operation cont’d

Loading

When loading and unloading the oven, stage products and racks so the oven doors are opened for the least amount of time.

Be sure that racks are level within the oven. Bent or warped pans can greatly affect the evenness of the cook or bake. If using baker’s parchment, be sure the parchment does not blow over the

product. The will create an uneven bake. Load each shelf evenly. Maintain equal space between the pan and oven

walls, front and back. Do not overload pan’s this will create an uneven bake. For best baking results, load the oven from the center out during random

loading.

CAUTION

ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM COMBUSTIBLE MATERIALS.

KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR FALLS.
