This part of BS 5871 specifies installation and maintenance requirements for open flued decorative fuel effect gas appliances of heat input not exceeding 20 kW (see Note 2) burning 2nd and 3rd family gases in rooms or internal spaces in domestic (see Note 4) or commercial premises, including public houses and restaurants.<\/p>\n

The provisions contained within this standard cover the selection of a suitable appliance, the ventilation and flueing requirements, and other measures necessary to ensure a safe installation.<\/p>\n

This standard applies to the installation of decorative fuel effect gas appliances in builder\u2019s openings, fireplace recesses, flue boxes or under associated independent canopies. (See Figure 5.) It does not cover the installation of flueless or room-sealed appliances.<\/p>\n

This standard is not applicable to mobile and portable appliances in conformity with BS EN 449 or to appliances in touring caravans.<\/p>\n

\n

NOTE 1 Attention is drawn to the foreword concerning fuel effect appliances which burn gas for a decorative effect. The only types of such appliance covered by this part of BS 5871 are those detailed in b) of the Commentary and recommendations on Clause 5<\/b> of this standard. Further guidance in this respect is given in Figure 1.<\/p>\n<\/blockquote>\n

\n

NOTE 2 Heat inputs in this document are based on net calorific value. Figures based on gross calorific value are given in parenthesis where deemed necessary. [See also Clause 5<\/b>, commentary and recommendations b).]<\/p>\n<\/blockquote>\n

\n

NOTE 3 Attention is drawn to the foreword concerning the installation of used appliances.<\/p>\n<\/blockquote>\n

\n

NOTE 4 As well as normally constructed dwellings, domestic premises include any permanently sited caravan holiday homes, residential park homes and permanently moored boats. See IGE\/UP\/8 [8].<\/p>\n<\/blockquote>\n

\n

NOTE 5 Appliances of over 20 kW: although many of the requirements within this standard will equally apply to appliances with a rated heat input in excess of 20 kW, additional or alternative requirements may also be applicable in order to achieve a safe installation. Reference should be made to the Building Regulations and supporting guidance or requirements thereto.<\/p>\n<\/blockquote>\n
