The pipework design shall take into account the composition and properties (e.g. specific gravity) of the fuel gas and the need for venting, purging and cleaning.

The pipework material shall comply with the relevant standards.

For steel pipes, compliance with EN 10208-1 and EN 10208-2, EN 13480-2:2002 (Table A.3), or EN 10255 is considered appropriate. For copper pipes compliance with EN 1057 is considered appropriate. Copper Soldering connections shall not be used for gas carrying parts where the temperature is likely to exceed 100°C.

Threaded pipe fittings shall comply with EN 10241 or EN 10242.

Metal is the preferred material for pipes and components but where appropriate and the same safety levels can be achieved then other materials can be utilized. Such materials and conditions of service shall be specified in the instructions for use.

Oscillations which may cause damage to pipework, components, safety systems shall be prevented (by firm anchoring and/or, use of flexible couplings).
