The 30” Single Wall Oven models offer the following cooking cycles:

 

Bake

(Natural Airflow Bake)

Full power heat is radiated from the U-shaped 
bake burners in the bottom of the oven cavity and 
is circulated with natural airflow. This function is 
recommended for single rack baking. Many cookbooks 
contain recipes to be cooked in the conventional 
manner. Conventional baking is suitable for dishes that 
require a high temperature. Use this setting for baking 
and preparing casserole dishes.

Convection Bake

Heat is radiated from the U-shaped bake burners 
in the bottom of the oven cavity. The heated air 
is circulated by one motorized fan in the rear of 
the oven providing a more even heat distribution. 
Multiple rack use is possible for the largest baking 
job. When roasting, cool air is quickly replaced—
searing meats on the outside and retaining more 
juices and natural flavor on the inside with less 
shrinkage. This even circulation of air equalizes 
the temperature throughout the oven cavity 
and eliminates the hot and cold spots found in 
conventional ovens.

Broil (Infrared Broil)

The broil burner at the top of the oven heats the 
metal screen until it glows. Heat radiates from 
the GourmetGlo™ infrared broiler located at the 
top of the oven cavity. The distance between the 
foods and the broil elements determines broiling 
speed. For “fast” broiling, food may be as close as 
2 inches (5 cm) to the broil element or on the top 
rack. “Fast” broiling is best for meats where rare to 
medium doneness is desired. Use this setting for 
broiling small and average cuts of meat.

Convection Broil

(Infrared Convection Broil)

The top element operates at full power. This 
function is exactly the same as regular broiling 
with the additional benefit of air circulation by 
the motorized fan in the rear of the oven. Smoke 
is reduced since the airflow also reduces peak 
temperatures on the food. Use this setting for 
broiling thick cuts of meats.
