More About This Product

Description
This First Edition National Standard of Canada has been reaffirmed effective February, 2016. There have been no technical changes made to the Standard. These requirements cover factory-built grease ducts and grease duct assemblies that are intended to be installed as alternatives to the grease ducts constructed of all welded 1.37 mm carbon steel or 1.09 mm stainless steel required by ULC-S650, Standard for the Installation and Performance of Ventilation and Fire Suppression Systems for Commercial and Institutional Cooking Equipment. Grease ducts covered by these requirements are intended to be installed in a fire rated enclosure when required by the provincial or territorial regulations or bylaws, or in the absence of those requirements by the National Building Code of Canada. Grease duct assemblies that penetrate fire rated assemblies which do not require the protection of a fire rated enclosure are covered by the requirements contained in CAN/ULCS144, Standard Method of Fire Resistance Test - Grease Duct Assemblies.
