6.2 Previously used and second hand cooking appliances A previously used or second hand appliance shall only be installed if it is:
a) in a serviceable and safe condition;
b) suitable for the gas being supplied;
c) ftted with a readable data plate. Conversion to another gas, if necessary, shall be carried out strictly in accordance with the manufacturer’s instructions, using the manufacturer’s kit of parts. For a previously used appliance, in the absence of manufacturer’s installation instructions the manufacturer shall be contacted to obtain the installation instructions. In the event that these are not available, the cooker shall be installed in accordance with the present standard. For a second hand appliance the cooker shall only be installed if the installation instructions have been obtained. COMMENTARY ON 6.2 For a second hand appliance it is a requirement of the Gas Cooking Appliances (Safety) Regulations 1989  that the manufacturer’s installation instructions are provided with the appliance. Where a previously used or second hand cooking appliance carries a CE mark, its data plate is required to carry the information on type of gas and appliance inlet pressure. Where a cooking appliance does not carry a CE mark, it has to be borne in mind that other criteria could apply, such as surface temperatures, cooking appliance stability, ventilation, etc., and these need to be taken into account in the method of installation.
