The appliance and flue are separated by a void which can be in one or more of the following forms:? fireplace recess;? builder’s opening;? metal flue box to BS 715;? pre-cast flue to BS EN 1858.The void is covered by a closure plate, which may be an integral part of the appliance, or a separate plate; in either case it is regarded as a part of the appliance and is supplied with it. These appliances are designed to discharge their products of combustion into the void behind the closure plate; they also have an integral flue break whichmay be in the form of a draught diverter or an open front.Although all appliances covered by this standard are radiant/convectors, they have traditionally been divided into the following types:? radiant/convectors;? live fuel effect (LFE);? inset live fuel effect (ILFE);This document does not apply to the following:? decorative fuel effect appliances;? catalytic combustion appliances;? appliances in which the supply of combustion air and/or the evacuation of the products of combustion is achieved by mechanical means;? appliances which permit automatic ignition whilst unattended. This standard is only intended for type testing.【中国标准分类号】: Q82【国际标准分类号】: 97_100_20【页数】: 102P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz! X2.5 |
