Describes installation and maintenance requirements for flued fixed space heating appliances burning 2nd and 3rd family gases for the purpose of heating rooms or spaces in domestic or commercial premises.

This part of BS5871 specifies installation and maintenance requirements for flued fixed space heating appliances burning 2nd and 3rd family gases for the purpose of heating rooms or spaces in domestic (see Note4) or commercial premises. It applies to appliances known as radiant gas fires, radiant convector gas fires, convector heaters, and heating stoves. Combined appliances of the type where a gas fire is used in conjunction with a boiler or circulator are also covered in so far as the installation of the combined appliance is concerned. This standard covers the selection of a suitable appliance, the flueing and/or ventilation requirements, and other measures necessary to ensure a safe installation. The central heating and/or hot water system connected to a combined appliance is not within the scope of this standard and reference should be made to BS5449 (see Note5) and BS5546 for this part of such an installation. This standard is not applicable to: mobile and portable appliances conforming to BSEN449; or appliances in touring caravans; or open-fronted radiant-convector heaters without a dress guard. Additional requirements for the installation of fire/back boilers and fire/back circulators are specified in Clauses 15, 16, 17 and 18. NOTE1 Attention is drawn to the foreword concerning fuel effect appliances which burn gas so as to simulate a solid fuel fire or produce other decorative effects. The only types of such appliances covered by this part of BS5871 are those detailed in i) of the commentary and recommendations on Clause5 of this standard. Further guidance in this respect is given in Figure1. NOTE2 Heat inputs in this document are based on net calorific value. Figures based on gross calorific value are given in parentheses where deemed necessary. (See also Clause5, commentary and recommendations, h). NOTE3 Attention is drawn to the foreword concerning the installation of used appliances. NOTE4 As well as normally constructed dwellings, domestic premises include any permanently sited caravans, holiday homes, residential park homes and permanently moored boats. See IGE/UP/8 [8]. NOTE5 BS5449 has been partly replaced by BSEN12828 and BSEN12831, and is to be withdrawn once BSEN14336 and BSEN14337 are published.
