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

The minimum distance required between the lowest edge of a grease filter and a burner without an exposed flame is established to ensure safe operation and prevent any potential fire hazards. Grease filters are crucial components in kitchen ventilation systems, designed to capture airborne grease particles.

In scenarios where burners are present, especially those without an exposed flame, maintaining a safe distance is essential to mitigate the risk of grease buildup that could ignite due to heat radiation or various operational factors. The correct choice indicates a distance of 0.5 feet (or 6 inches), which is grounded in fire safety codes and industry practices.

This specified minimum distance is intended to provide adequate airflow and prevent any heat transfer that could lead to grease ignition. Distances greater than this may apply in different contexts or with specific equipment configurations, but for the standard case of burners without flames, 0.5 feet is the recognized requirement.
