How should cooking appliances be installed in relation to the cooking top or oven racks?

Cooking appliances, such as stoves and ovens, should be installed level to ensure safe and efficient operation. When appliances are level, it allows for proper heat distribution, which can prevent uneven cooking and potential hazards. For example, if a stove or oven is not level, liquids may not flow correctly, which could lead to spillage or an increased risk of fire due to cooking oils or other materials pooling in unsafe areas.

Level installations also facilitate the proper functioning of components like gas burners, ensuring that flames burn evenly and effectively. In addition, this helps maintain safety standards during operation, as appliances that are not level may inadvertently cause injuries or lead to dangerous situations when cooking.

The other options—sloped, inclined, and raised—do not provide the stability and safety required for cooking appliances. These configurations could lead to improper functioning, increased risk of accidents, and could violate local safety codes regarding appliance installation. Therefore, having cooking appliances installed level is crucial for both safety and effectiveness in the kitchen.
