17、ers. 1.2 Wall protectors, oor protectors, and hearth extensions are intended for installation in accordance with the Standard for Chimneys, Fireplaces, Vents, and Solid-Fuel Burning Appliances, NFPA 211. 1.3 The factory-built replaces with which these products are used are intended to comply with th
18、e Standard for Factory-Built Fireplaces, UL 127. 1.4 The replace stoves with which these products are used are intended to comply with the Standard for Fireplace Stoves, UL 737. 1.5 The solid-fuel type room heaters with which these products are used are intended to comply with the Standard for Room
19、Heaters, Solid-Fuel Type, UL 1482. 1.6 The pellet-fuel type room heaters with which these products are used are intended to comply with the Standard for Room Heaters, Pellet Fuel-Burning Type, ASTM E1509. 1.7 Floor protectors are not evaluated in regard to oor protection with substantial amounts of
20、fuel burning directly on the oor protector surface. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered
21、by this standard. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall b
22、e used in accordance with its rating established for the intended conditions of use. 2.4 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
23、 specied limits, and shall be used only under those specic conditions.

25、tandard. 5 Glossary 5.1 For the purpose of this standard, the following denitions apply. 5.2 FLOOR PROTECTOR Noncombustible surfacing applied to the oor area underneath and extending in front, to the sides and to the rear of a heat producing appliance. a) TYPE 1 EMBER PROTECTOR for appliances not re
26、quiring thermal protection of the combustible oor during normal operation. b) TYPE 2 THERMAL FLOOR PROTECTOR for appliances requiring thermal protection of the combustible oor during normal operation. To qualify as a Thermal Floor Protector, the oor protector must have a minimum R-Value of 1.0 when
27、tested using the method prescribed in Section 11 of this standard. 5.3 HEARTH EXTENSION Noncombustible surfacing applied to the oor area extending in front of and at the sides of the hearth opening of a replace or replace insert. Hearth extensions are subject to the same classications, testing and r
28、equirements as Ember Protectors and Thermal Floor Protectors dened in 5.2. 5.4 NONCOMBUSTIBLE MATERIAL A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release ammable vapors when subjected to re or heat as specied i
29、n the Radiant Panel Test, Section 12, and in the Burning Brand Test for Floor Protectors, Section 13. Materials reported as noncombustible, when tested in accordance with the Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750C, ASTM E136, are considered noncombustible m
30、aterials. 5.5 PRODUCT All wall protectors, oor protectors, and hearth extensions or any part thereof covered by these requirements unless specically noted otherwise. 5.6 R-VALUE The measure of a materials ability to resist heat ow Thermal Resistance, units = ft 2 x F x hour/Btu.

32、ide of the oor protector facing the stove. Material shall form a continuous covering without gaps. All materials shall maintain their structural and thermal integrity throughout the required testing. Exception: Combustible trim shall not be considered part of the oor protection area if the combustib
33、le trim is completely outside the minimum oor protection dimensions specied in the appliances installation instructions, see 18.2(a). See Figure 6.1 for an example. This is generated text for gtxt. 6.2 For an ember protector as specied in 5.2(a), combustible materials may be used underneath the nonc
34、ombustible covering described in 6.1. 6.3 A thermal oor protector as specied in 5.2(b) shall be tested as if any combustible materials used in the construction of the oor protector were the combustible oor. The thermocouples shall be attached to the top surface of the upper-most layer of any combust
35、ible material within the oor protector structure. The test limits are to be applied as if the combustible materials were the oor. The R-value given for a thermal oor protector containing combustible materials shall be the thermal resistance from the top surface of the oor protector to the top surfac
36、e of the upper-most layer of combustible material within the oor protector.
