The prevailing codes provide detailed information on the design and construction requirements that a CKV hood must adhere too. A qualified sheet metal mechanic can design and manufacture a hood to the prevailing codes and thus the hood can meet the codes requirements. CKV hoods do not have to be Listed to be installed in a commercial kitchen.
Non-Listed hoods will most likely undergo a more detailed inspection process by the Authority Having Jurisdiction as a result of the lack of third party testing and certification laboratory.
