IMPORTANT NOTICE TO INSTALLERS
Installers should satisfy themselves that the gas pipework installation is carried out in
accordance with all current legislation, Codes of Practice and
recommendations .
Additionally it may be necessary to protect the gas valves which form part of
the heater or burner assembly from potential pipe contamination particularly,
but not exclusively , where copper gas pipework is used.
In instances where copper pipework is to be used for all or part of a gas
pipework installation, including short length final connections then we advise
that installers consult with gas supplier or provider and satisfy themselves what
additional precautions may be necessary
