DW/172 HVCA Specification for Kitchen Ventilation Systems
DW/172 is a definitive guide to kitchen ventilation systems in non-domestic properties. This publication has evolved to incorporate legislative change and new standards, and represents the most up-to-date and indispensable industry specification for HVAC specialists serving the catering sector.
DW/172 includes a new standard for grease filter testing from the Loss Prevention Council (LPS1263), endorsed by the Association of British Insurers (ABI). This section sets the standards demanded by British insurers to reduce the risk of fire in commercial kitchens and features detail on the certification of grease filters. In addition, the already comprehensive section on appliances and their coefficients has been further expanded, and advice has been included on the requirements for an interlock between the ventilation system and gas supply.
DW/172 clearly details all the requirements for the design, installation and maintenance of kitchen ventilation systems. DW/172 is a progression of the popular DW/171 that became the industry benchmark for kitchen ventilation systems after it was published in 1999, and is now a key part of HVCA Publications suite of literature intended to set standards for ductwork service and maintenance.
