For cooking equipment without exposed flame where flue gases bypass grease removal devices, the minimum vertical distance is not less than how many inches?

For cooking equipment without exposed flame where flue gases bypass grease removal devices, the minimum vertical distance is not less than how many inches?

• A. 4 inches
• B. 6 inches
• C. 8 inches
• D. 12 inches

Answer: (B)

The safety idea here is to provide a vertical separation between cooking equipment and the grease removal path when there’s a risk that flue gases could bypass the grease-removal devices. For equipment without exposed flame, the standard requires a minimum six-inch vertical distance. This gap gives heat a bit more room to dissipate and cool before it reaches the grease-laden surfaces in the hood or duct, reducing the chance that bypassed hot gases ignite grease or overwhelm the grease removal system. In short, six inches is the required clearance to lower ignition risk when bypass is possible.
