terminals in your plug. In this case proceed as follows:-
The wire coloured green and yellow must be connected to the terminal in the plug that is marked with the letter E, or by the
earth symbol
, or coloured green or green and yellow.
The blue wire must be connected to the terminal which is marked with either the letter N or coloured black.

8 FAULT FINDING FOR THE USER
Current Gas Safety (Installation and Use) Regulations:-
It is the law that all gas appliances are installed and serviced by a competent person, i.e. Gas Safe registered personnel.
Failure to install or service appliances correctly could lead to prosecution. It is in your interest and that of safety to ensure
compliance with the law. The manufacturer's instructions must not be taken in any way as over-riding statutory obligations.
The Benchmark Checklist must be fully completed by the installer on installation of the boiler. The Benchmark Checklist is
shown in back of the Installation and Servicing instructions. All Gas Safe registered installers carry a Gas Safe ID card and
have a registration number. Both should be recorded in the Checklist. You can check your installer is Gas Safe registered by
calling Gas Safe on 0800 408 5500.
