Reference Standards In the United Kingdom, the installation and initial start-up of the boiler must be by a CORGI registered installer in accordance with the installation standards currently in effect, as well as with any and all local health and safety standards i.e. CORGI. In the Republic of Ireland the installation and initial start-up of the appliance must be carried out by a Competent Person in accordance with the current edition of I.S.813 “Domestic Gas Installations” and the current Building Regulations, reference should also be made to the current ETCI rules for electrical installation. The installation of this appliance must be in accordance with the relevant requirements of the Local Building Regulations, the current I.E.E. Wiring Regulations, the by-laws of the local authority, in Scotland, in accordance with the Building Standards (Scotland) Regulation and Health and Safety document No. 635, “Electricity at Work Regulations 1989” and in the Republic of Ireland with the current edition of I.S. 813 and the Local Building Regulations (IE). C.O.S.H.H. Materials used in the manufacture of this appliance are non-hazardous and no special precautions are required when servicing. Codes of Practive Installation should also comply with the following British Standards Code of Practice: BS 7593:1992 Treatment of water in domestic hot water central heating systems BS 5546:1990 Installation of hot water supplies for domestic purposes BS 5440-1:2008 Flues BS 5440-2:2008 Air supply BS 5449:1990 Forced circulation hot water systems BS 6798:2000 Installation of gas fired hot water boilers of rated input not exceeding 70kW BS 6891:1989 Installation of low pressure gas pipes up to 28mm BS 7671:2001 IEE Wiring Regulations BS 4814:1990 Specification for expansion vessels BS 5482:1994 Installation of L.P.G. Domestic heating compliance guide and in the Republic of Ireland in accordance with the following codes of practice: I.S. 813 Domestic Gas Installations installation Avoid installing the boiler where the air inlet can be polluted by chemical products such as chlorine (swimming pool area), or ammonia (hair dresser), or alkalin products (launderette). Flue Detailed information on flue assembly can be found in the “Connecting the Flue” section. The boiler must be installed so that the flue terminal is exposed to the free passage of external air at all times and must not be installed in a place likely to cause nuisance. It must not be allowed to discharge into another room or space such as an outhouse or closed lean-to. Condensing boilers have a tendency to form a plume of water vapour from the flue terminal due to the low temperature of the flue gases. The terminal should therefore be located with due regard for the damage or discolouration that may occur to building within the vicinity and consideration must also be given to adjacent boundaries, openable windows etc. The minimum acceptable clearances are shown on page 12. 11
