Which section mentions that the commercial cooking appliances must have a specific installation?

Section 507 is specifically dedicated to the installation and safety requirements for commercial cooking appliances. This section outlines essential criteria like clearance requirements, ventilation systems, and proper installation practices that are crucial for ensuring safe operation in commercial kitchens. The intent is to prevent fire hazards, ensure proper functioning, and comply with health and safety standards. This focus on commercial cooking appliances makes this section the authoritative source for guidelines pertaining to their installation.

The other sections, while relevant to different aspects of mechanical systems or general installation requirements, do not address commercial cooking appliances with the same level of specificity as Section 507. This distinction clarifies why Section 507 is the correct choice for installation requirements related to commercial cooking appliances.
