29、TION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover factory-built replaces, including the re chamber, chimney, roof assembly, and other related parts that are entirely factory-made and that are intended for unit assembly in the eld. 1.2 These requirements cover factory-

30、built replaces having a re chamber intended to be operated either open to a room or, when equipped with doors, operated with the doors either open or closed. 1.3 These requirements cover factory-built replaces intended for use with either solid wood or coal fuels. 1.4 The factory-built replaces cove

31、red by these requirements are intended for installation in accordance with the National Fire Protection Association Standard for Chimneys, Fireplaces, Vents and Solid-Fuel Burning Appliances, NFPA 211, the International Mechanical Code, and the Uniform Mechanical Code. 1.5 As covered by these requir

32、ements, an air duct system portion of a circulating warm air type replace is intended for installation in accordance with the National Fire Protection Association Standard for Warm Air Heating and Air Conditioning Systems, NFPA 90B. 1.6 These requirements also cover xed blowers, and other electrical

33、 accessories for factory-built replaces, rated at 600 volts or less, and intended to be employed in specied locations in accordance with the National Electrical Code, NFPA 70. 1.7 The chimneys for factory-built replaces covered by these requirements comply with either a 1700F (927C) ue-gas temperatu

34、re test or a 2100F (1149C) ue-gas temperature test, at the manufacturers option. 1.8 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 re, electric shock, or injur

35、y to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this Standard is maintained. A product whose features, characteristics, components, materials, or systems conict wi

36、th specic requirements or provisions of this Standard shall not be judged to comply with this Standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard. JULY 27, 2016 FAC

38、 air duct system attached to the re chamber so that heated air is directed to areas or locations other than directly in front of or above the re chamber opening. 2.3 COMBUSTIBLE MATERIAL, NONCOMBUSTIBLE MATERIAL As used in these requirements, these terms are dened in the Standard Glossary of Terms R

39、elating to Chimneys, Vents, and Heat- Producing Appliances, NFPA No. 97M. 2.4 CONVECTION SYSTEM An air heating system through which air is circulated by convection. It relies upon an integral fan or blower. 2.5 HEARTH The oor area within the re chamber of a replace upon which the re is built. 2.6 HE

40、ARTH EXTENSION The noncombustible surfacing applied to the exposed combustible oor area external to the hearth, as specied in the installation instructions. 3 Components 3.1 General 3.1.1 A component of a product covered by this standard shall: a) Comply with the requirements for that component as i

41、ndicated in 3.2 3.12; b) Be used in accordance with its rating(s) established for the intended conditions of use; c) Be used within its established use limitations or conditions of acceptability; d) Additionally comply with the applicable requirements of this end product standard; and e) Not contain

42、 mercury. Note - Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. E

43、xception No. 1: A component of a product covered by this standard is not required to comply with a specic component requirement that: a) Involves a feature or characteristic not required in the application of the component in the product, b) Is superseded by a requirement in this standard, or c) Is

44、separately investigated when forming part of another component, provided the component is used within its established ratings and limitations. Exception No. 2: A component complying with a UL component standard other than those cited in 3.2 3.12 is acceptable if: APRIL 21, 2011 FACTORY-BUILT FIREPLA

45、CES - UL 127 8UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL a) The component also complies with the applicable component standard of 3.2 3.12; or b) The component standard: 1) Is compatible with the ampacity and overcurrent protection requ

46、irements NFPA 70, where appropriate; 2) Considers long-term thermal properties of polymeric insulating materials in accordance with the Standard for Polymeric Materials Long Term Property Evaluations, UL 746B, and 3) Any use limitations of the other component standard is identied and appropriately a

47、ccommodated in the end use application. For example, a component used in a household application, but intended for industrial use and complying with the relevant component standard may assume user expertise not common in household applications. 3.1.2 A component that is also intended to perform othe

48、r functions, such as over current protection, ground-fault circuit-interruption, surge suppression, any other similar functions, or any combination thereof, shall comply additionally with the requirements of the applicable UL standard(s) that cover devices that provide those functions. Exception: Wh

49、ere these other functions are not required for the application and not identied as part of markings, instructions, or packaging for the appliance, the additional component standard(s) need not be applied. 3.1.3 A component not anticipated by the requirements of this standard, not specically covered by the component standards of 3.2 3.12, and that involves a potential risk of electric shock, re, or personal injury, shall be additionally investigated i
