适用范围

This standard does not cover: a) liquefied petroleum gas (LPG) installations covered by BS 5482-2 and installations with gases covered by PD 5482-3; b) gas installations in caravans, holiday homes or residential park homes conforming to BS EN 721 or BS 3632 as appropriate, which were installed at the time of construction; c) decorative fuel effect gas appliances, covered by BS 5871-3; or d) multiple cooking appliance installations in catering establishments and schools. NOTE 1 Although this part of BS 5440 has been developed mainly for use with gas appliances that carry the CE mark, it may also be used for installations of gas appliances which are not required under the Gas Appliances (Safety) Regulations to carry the CE mark, such as used appliances. NOTE 2 Maintenance requirements relating to existing vents are specified in Clause 8. NOTE 3 It is essential that the installer checks the data given with an appliance to establish the basis on which the heat input is given. The data in this standard refer to heat input expressed in terms of net CV with conversion given for natural gas gross CV quoted in brackets, where appropriate. NOTE 4 The ratio of gross:net heat input is approximately 1.11:1 for natural gas, 1.09:1 for propane and 1.08:1 for butane. For example, 9 kW input based on gross CV for natural gas is converted to the equivalent net CV input as follows: Net input = 9.0/1.11 = 8.1 kW. NOTE 5 For requirements for the installation and maintenance of gas‑fired catering appliances for use in all types of catering establishments (2nd and 3rd family gases), see BS 6173. Further information regarding volume air flow rates in the catering environment can be found in DW 172, Specification for kitchen ventilation systems, and CAIS 23, Gas safety in catering and hospitality.
