OPERATING INSTRUCTIONS
TEMPERATURE
Most products require lower temperatures than suggested for deck or range ovens. A standard temperature
reduction of 25°F-30°F is recommended as a starting point. Actual baking will vary pending product weight
and consistency. If the edges of the product are done and the center is still raw or there is extensive color
variation, reduce the thermostat setting by 15°F-25°F until the desired results are achieved. Excessive
temperatures will not reduce baking time.
TIME
Convection ovens generally bake 20% faster than deck or range ovens even though lower temperatures are
used. Most recipes can be converted by having shorter cooking times and/or reducing your cooking
temperatures.
• Frozen food products will require more time than refrigerated products
• 3 trays of food product will require more cook time than 1 tray of food product
PRODUCTS
Load the oven from the bottom up. To ensure even baking, equal amounts of similar products should be used
on each pan.
