Working on the system
■ Isolate the system from the power
supply (e.g. by removing the separate fuse or by means of a mains isolator) and check that it is no longer
'live'.
■ Safeguard the system against reconnection.
■ Where gas is used as the fuel, close
the main gas shut-off valve and safeguard it against unintentional reopening.
