If a baffle plate is used, what clearance is required and how far must it be from the filters?

• A. 6 inches clearance and 4 inches from filters
• B. 8 inches clearance and 4 inches from filters
• C. 8 inches clearance and 6 inches from filters
• D. 10 inches clearance and 6 inches from filters

Answer: (C)

When a baffle plate is used in a kitchen exhaust system, it must be spaced so there’s enough room for proper air flow, heat dissipation, and maintenance access. The required setup is eight inches of clearance from surrounding surfaces and at least six inches between the baffle plate and the filters. That eight-inch gap helps ensure hot grease-laden air doesn’t transfer excessive heat to nearby components and provides space for inspection and cleaning of the baffle plate itself. The six-inch distance from the filters keeps the plate clear of the filter elements, preventing interference with filter removal and replacement, and helps prevent grease buildup or air channeling issues that could reduce filtration efficiency. Other, smaller clearances could impede service or airflow and compromise safety and performance, while the specified eight inches and six inches meet the standard’s minimums for safe, effective operation.
