609.5.2.2 Maintenance of airflow.

FC § 609.5.2.2

The required rate of exhaust airflow for the commercial cooking exhaust system shall be maintained at all times. Fixed air supply openings installed to provide make-up air for air exhausted through the exhaust system shall not be restricted by covers, dampers, or any other means that would reduce the operating efficiency of the exhaust system. The department may require that the exhaust system be tested in accordance with the Mechanical Code if, upon inspection, the exhaust airflow appears to be insufficient to allow proper exhausting of grease vapors, steam, fumes, smoke and/or odors.
