The dodument cover requirements for electrically operated damper assemblies, that are intended for installation in the vent or chimney connector of automatically operated oil-fired appliances employing an atomizing type oil burner. The damper assembly is intended to restrict or block the connector opening when the burner is not firing. These requirements cover automatic vent or chimney connector dampers for oil-fired appliances having a flue gas temperature not in excess of 538 ?C (1000 ?F), unless marked for a lower temperature. The vent or chimney connector dampers covered under these requirements are not for use on oil-fired appliances that employ vaporizing type oil burners. Automatic vent or chimney connector dampers are intended for installation in accordance with the following standards of the National Fire Protection Association: a) Oil-Burning Equipment, NFPA 31. b) Chimneys, Fireplaces, and Vents, NFPA 211. c) National Electrical Code, ANSI/NFPA 70. A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
