This part of BS5440 specifies the requirements for the installation and maintenance of ventilation provision relating to gas appliances utilizing 1st, 2nd or 3rd family gases, with a rated heat input not exceeding 70kW based on net CV (net calorific value), used for domestic or non-domestic purposes. This standard does not cover: liquefied petroleum gas (LPG) installations covered by BS5482‑2 and installations with gases covered by PD 5482-3; gas installations in caravans, holiday homes or residential park homes conforming to BSEN721 or BS3632 as appropriate, which were installed at the time of construction; decorative fuel effect gas appliances, covered by BS5871‑3; or multiple cooking appliance installations in catering establishments and schools. NOTE1 Although this part of BS5440 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 [1] to carry the CE mark, such as used appliances. NOTE2 Maintenance requirements relating to existing vents are specified in Clause8. NOTE3 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. NOTE4 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, 9kW input based on gross CV for natural gas is converted to the equivalent net CV input as follows: NOTE5 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 BS6173. Further information regarding volume air flow rates in the catering environment can be found in DW 172, Specification for kitchen ventilation systems [2], and CAIS 23, Gas safety in catering and hospitality [3].
