7、896:2011This page deliberately left blankii BSI 2011ForewordPublishing informationThis British Standard is published by BSI and came into effect on 30 June 2011. Itwas prepared by Panel GSE/30/-/17, Non Domestic Radiant Heaters, under theauthority of Technical Committee GSE/30, Gas Installations (1s
8、t, 2nd and 3rdfamily gases). A list of organizations represented on this committee can beobtained on request to its secretary.SupersessionThis British Standard supersedes BS 6896:2005, which is withdrawn.Information about this documentThis is a full revision of the standard. The standard has been up
9、dated to reflectchanges in installation practice and legislation.This standard allows manufacturers instructions to specify a method ofinstallation, testing, commissioning or maintenance which differs in points ofdetail from this standard. This reference to manufacturers instructions isallowed only
10、where it results in at least an equivalent level of safety. It isimportant that the manufacturers instructions are followed. This standard isapplicable where manufacturers instructions do not give specific advice.Presentational conventionsThe provisions of this standard are presented in roman (i.e.
11、upright) type. Itsrequirements are expressed in sentences in which the principal auxiliary verb is“shall”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does
12、 not purport to include all the necessary provisions of acontract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.In particular, attention is drawn to the following regulations which may beamended from time to time. T
13、he commentary in this British Standard reflectsthe state of the regulations in 2010. The Gas Appliances (Safety) Regulations 1;This standard only applies to appliances falling within the scope of theseregulations. The Gas Safety (Installation and Use) Regulations 2;These control all aspects of the w
14、ays in which gas-fired appliances andsystems may be installed, maintained and used, mainly in domestic andcommercial premises, and the classes of persons who may undertake gaswork.NOTE These regulations currently do not apply to industrial premises, exceptthose parts used for domestic purposes and s
15、leeping accommodation.

18、H STANDARDBS 6896:2011iv BSI 20111 ScopeThis British Standard specifies the installation requirements for gas-firedoverhead radiant heaters and systems for the environmental heating of premisesother than domestic dwellings. This standard only applies to appliances fallingwithin the scope of the Gas
19、Appliances (Safety) Regulations 1995 1.It is applicable to the installation of heaters that are designed to use gases ofgroup H of the 2nd family (e.g. natural gas), gases of group P of the 3rd family(e.g. propane) as well as gases of group B of the 3rd family (e.g. butane)(see BS EN 437+A1).NOTE 1
20、This standard does not specifically cover LPG/air for which additionalrequirements might be necessary.It is applicable to the installation of gas-fired overhead luminous radiant heatersconforming to BS EN 419-1, single burner gas-fired overhead radiant heatersconforming to BS EN 416-1 and multi-burn
21、er gas-fired overhead radiant tubeheater systems conforming to BS EN 777-1, BS EN 777-2, BS EN 777-3 andBS EN 777-4.NOTE 2 For the purposes of this standard, installation includes design, inspectionand commissioning. It is recognized that each of these tasks may, at times, beperformed by the same pe
22、rsons.NOTE 3 The heat inputs and ventilation rates in cm2/kW of heat input given in thisstandard are based on the net calorific value.It is not applicable to the installation of gas-fired overhead radiant heaters andsystems:a) to which the Gas Appliances (Safety) Regulations 1995 1 do not apply;b) t
23、hat are designed for use in domestic premises;c) that are supplied with a heated fluid from a separate source; ord) that are portable or transportable.2 Normative referencesThe following referenced documents are indispensable for the application ofthis document.
