2、UTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULUL Standard for Safety for Unvented Kerosene-Fired Room Heaters and Portable Heaters, UL 647Second Edition, Dated May 3, 1993Summary of TopicsThese revisions to UL 647 are being issued to address universal upkeep of UL Stand
3、ards forSafety. These revisions are considered to be non-substantive and not subject to ULs STPprocess.Text that has been changed in any manner or impacted by ULs electronic publishing system is markedwith a vertical line in the margin. Changes in requirements are marked with a vertical line in the
4、marginand are followed by an effective date note indicating the date of publication or the date on which thechanged requirement becomes effective.A reference to UL 60730-1 and/or a Part 2 standard from that series has been added to this standard.The addition of this reference provides an alternate s
5、tandard for investigating components currentlycovered by UL 873 until October 19, 2016. This added reference will facilitate the use of components thathave been investigated to the UL 60730 series. Such components have been determined to fulfill therequirements of the legacy standards.UL 60730-1 (4t
6、h Edition) becomes effective on October 19, 2016. All components that were previouslyinvestigated to the requirements in UL 873 will have to comply with the requirements in either UL 60730-1and/or a Part 2 standard from that series in order to maintain UL Listing or Recognition, as appropriate.UL 87
7、3 legacy control standard will be withdrawn on October 19, 2016.This is intended to provide end product manufacturers with sufficient time to a) address the impact of thestandards changes during normal design changes over the intervening years, b) submit any modifiedproducts for investigation, and c
8、) implement any necessary changes in production.All rights reserved.

30、RODUCTION1 Scope1.1 These requirements apply to unvented kerosene-fired room heaters and portable heaters as definedherein. They are for use with Type 1-K Kerosene, and Synthetic Fuels complying with the Outline ofInvestigation for Synthetic Fuels for Listed Kerosene-Fired Portable Heaters and Keros
31、ene-Fired RoomHeaters, Subject 647A, in spaces that are well ventilated to provide the supply of air required forcombustion and to reduce the risk of accumulation of carbon monoxide. These heaters are for attendedor unattended use. These products are required to be equipped with automatic primary sa
32、fety controls orto be inherently constructed to prevent abnormal discharge of fuel at the burner in case of ignition failureor premature flame extinguishment. They are not intended for use under the following conditions:a) In spaces in which flammable vapors or gases may be present, orb) As cooking
33、appliances.1.1 revised April 16, 20101.2 Requirements for the installation and use of kerosene-fired room heaters and portable heaters areincluded in the Standard for the Installation of Oil-Burning Equipment, NFPA 31 and in codes such as theBOCA National Mechanical Code, the SBCC Standard Mechanica
34、l Code, and the ICBO/IAPMO UniformMechanical Code.1.3 The maximum fuel-input rating for kerosene-fired room heaters is 30,000 Btu per hour (31.65 MJ) andfor kerosene-fired portable heaters is 25,000 Btu per hour (26.38 MJ).1.4 These requirements cover kerosene-fired room heaters and portable heaters
