IMPORTANT: When changing components ensure that
both the gas and electrical supplies to the boiler are
isolated before any work is started. When the
component has been changed turn the selector switch
fully anticlockwise against the spring pressure to the
reset position and hold for 5 seconds to reset the boiler
before recommissioning.
