What is the minimum distance required between the lowest edge of a grease filter and the cooking surface of an appliance without exposed flame?

The minimum distance required between the lowest edge of a grease filter and the cooking surface of an appliance without exposed flame is commonly set at 0.5 feet. This specification is crucial in ensuring the effective collection of grease and smoke during cooking operations. A distance of 0.5 feet allows the filtration system to capture airborne grease before it can settle on nearby surfaces, which reduces fire hazards and improves air quality.

Maintaining this minimum distance is important for the grease filter's efficiency, ensuring that it can function properly without obstruction from the cooking appliance or other installations. Standards in mechanical code often prioritize safety and performance, making this distance a key consideration for kitchen ventilation design.
