A combi-oven is a versatile piece of equipment that combines three modes of cooking in one oven,Guest Posting steam, circulated hot air or a combination of both. The combi mode is used to re-heat foods and to roast, bake and "oven fry". The steam mode is ideal for rapid cooking of vegetables and shellfish. The hot air mode operates as a normal convection oven for baking cookies, cakes and pastries. The combi mode decreases overall cook times, reduces product shrinkage and eliminates flavor transfer when multiple items are cooked simultaneously.

OVEN MODES: Select Oven mode, combi, hot air or steam. Refer to cooking guide at bottom of guideline card for recommended cooking mode and times for individual items.

COMBI MODE: Use to roast and braise meats, bake poultry and fish and reheat prepared foods. The combination of steam and hot air will improve yield and reduce overall cooking times. To OVEN FRY, use food items that are labeled "ovenable" by the manufacturer. Refer to cooking guideline for oven frying individual items at bottom of guideline card. Place items on perforated sheet pan in a single layer. DO NOT place excess amount of product on pan. A solid sheet pan may be placed under perforated pan to catch excess oils and eliminate smoke.

HOT AIR MODE: Use to bake cakes, cookies and breads and to roast and bake meats and poultry. The hot air mode circulates air in the same manner as a convection oven. NOTE: For convection oven guideline information read AFRS A-23-1 and A-23-2.

STEAMING MODE: Use to steam fresh, frozen or canned vegetables and shellfish. Use of the Combi-oven to steam foods can save time, labor, and help maintain appearance, and preserve nutrients, normally lost by other cooking methods. The oven is ideal for steaming more than one type of vegetable at the same a time without flavor transfer. Foods may be steamed in perforated or solid pans. Perforated Pans are usually used, particularly for vegetables, unless the cooking liquid is retained or manufacturer's directions specify solid pans. Pans are normally filled no more than 2/3 full to allow steam to circulate for even cooking.

Steam temperature is preset at 212° F. The cooking time will vary depending on the type of food and the number of pans in the oven. The cooking time should include the time it requires to heat food up to cook temperature, as well as steaming. Be sure to record the most successful steaming times on the recipe card for future reference.

TEMPERATURE SETTING: Note: At this time the AFRS recipes do not contain combi-oven information. Refer to cooking guideline at bottom of guideline card for individual items or begin by using the recommended convection oven temperature noted on individual recipes. If food is cooked around the edges, but the center is still raw or not thoroughly cooked, or if there is too much color variation (some is normal), turn pan or reduce the heat by 10°F. to 15°F. and return food to the oven and continue cooking until done. Be sure to record the most successful temperature on the recipe card for future reference.

TIME SETTING: Follow the recommended convection cooking times on recipe cards. Check progress halfway through the cooking cycle since times will vary in the Combi mode with the quantity of food being cooked, the temperature, and the type of pan used.

MEAT PROBE: The meat probe measures a product core temperature during the cooking process. Use of the meat probe is recommended for the cooking of all meats. It is the most accurate method of determining the temperature and doneness of a product.

FAN SPEED SETTING: See general operations notes below.


  1. OVEN RACKS: Position oven racks for the number of pans and product to be cooked.


  2. WATER SUPPLY: Verify water supply is on.


  3. SELECT COOKING MODE AND TEMPERATURE: Turn oven on; SELECT the cooking mode. To cook in the combi or hot air mode, set thermostat to desired temperature. To cook in the steam mode, set thermostat to 200°F. The thermostat light will come on indicating oven temperature is below set point.


  4. PREHEAT: Heat oven until thermostat light goes out indicating that the oven has reached the set temperature. The oven should preheat to 350°F. within 10 to 15 minutes. (Note: To conserve energy, DO NOT turn the oven on until 15 minutes before actual cooking time is to begin.)


  5. FAN SPEED: If two-speed fan is available, adjust the fan to recommended speed noted on individual recipe card. NOTE: The Combi-oven is equipped with electric interlock, which energizes/de-energizes both the heating element and fan motor when the doors are closed and open. Therefore, the heating elements and fan will not operate with the doors open, only when closed.


  6. MEAT PROBE: Insert the meat probe in the thickest section of the product. NOTE: The tip of the probe should not be placed near bone or fat. This will result in inaccurate temperature readings. Turn the meat probe switch on and set the desired core temperature by using the up or down arrows. Press the set button to store the set point temperature. Set the timer to the STAY ON position. When the selected core temperature is reached the buzzer will sound and the oven automatically turns off.


  7. CLEANING AND MAINTENANCE: Refer to the manufacturer's operating manual for cleaning and maintenance instructions. NOTE: Wipe out all spills as soon as they occur for ease of cleaning.
