What is the minimum clearance required when using a clearance reduction system with 28 gauge steel?

The minimum clearance required when using a clearance reduction system with 28 gauge steel is 9 inches. This requirement is specified to ensure that there is adequate space to prevent ignition of combustible materials and to allow for proper ventilation and heat dissipation. The 9-inch clearance helps to mitigate the risks associated with heat transfer and ensures that any potential flammable residues do not come into direct contact with hot surfaces.

This standard is part of the NFPA 96 guidelines, which aim to maintain safe cooking environments by establishing clearances that promote fire safety and prevent hazards associated with commercial cooking operations. Adhering to this specification is crucial for compliance with safety regulations and helps protect both property and individuals in commercial kitchen settings.
