Codes and Standards for CKV hood Ventilation
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 [...]
A Non-Listed hood has the advantage of not having to be manufactured to a specific set of length, height and/or depth dimension as well any specific geometric shape depicted in the manufacturer's hood listing. Therefore a Non-Listed hood can be made in any combination of size and/or shape as long as it meets the [...]
The most common CKV hood design is an exhaust only wall mounted canopy box design Hood (WCBD). The WCBD is designed for the back of the hood to be mounted against a wall, over the top of the cooking equipment and the cooks and is manufacturing in the shape of a rectangle (box). The [...]
Listed hood designs are individually tested for capture and containment over temperature controlled cooking equipment by a third party testing and certification lab. The results of capture and containment test are documented and included as part of the hoods listing. The manufacture can then engineer the minimum exhaust air flows of that hood design [...]
The minimum amount of air that a Listed CKV hood is required to exhaust is determined by capture and containment tests that were observed by the third party testing and certification laboratory on each specific design. Each Listed hood design has its own listing requirements and must be installed in accordance to them. [...]
Most National Mechanical and Fire Codes and Standards require that the CKV Type 1 hood systems shall be designed and installed to automatically activate the exhaust fan whenever cooking operations occur. If the CKV Exhaust fan is not manually turned on when the cooking equipment is in use, then an auto fan start will [...]
The national codes and standards require that all grease filters for Type I CKV hoods be Listed to the Underwriters Laboratories Standard #1046.
The Standard for Grease Filters for Exhaust Ducts UL 1046 is the standard by which Grease Extractors are tested. Products covered by these requirements are single-stage and multi-stage grease filters. These grease filters are intended for installation and use in accordance with the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, [...]
CKV Type II hoods do not require grease filters. Type II hoods are designed to be used primarily over non-grease producing cooking appliances where there is a need to exhaust excess heat, vapor and odor from the air. The main goal of using a Type II hood is to create a more comfortable cooking environment [...]
There are no current national codes or standards that include a minimum grease extraction efficiency that a filter for a CKV Hood must achieve; currently there are several air quality management districts that are considering minimum grease extraction efficiency requirements for filters for CKV hoods.
