UL 710B OUTLINE
Outline of Investigation for Recirculating Systems
|Publication Date:||9 June 2003|
These requirements cover commercial electric cooking appliances provided with integral recirculating systems (previously referred to as ductless hoods) and nonintegral recirculating systems, both of which are intended for installation in commercial establishments for the preparation of food. These devices incorporate an air filtering system enclosed in a hooded or otherwise contained area intended to capture air from the cooking process area. The hood assembly generally includes a fan, collection hood, or equivalent design feature, air filtering system (consisting of a grease filter with other filters), a fire actuated damper, and a fire extinguishing system unit. An integral recirculating system of a vending machine is also covered by this supplement.
These products are intended for installation in accordance with the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, NFPA 96.
The cooking section of the appliance shall comply with the requirements in the Standard for Commercial Electric Cooking Appliances, UL 197, as applicable, except as modified or superseded by the requirements in this Outline.
