GENERAL
INFORMATION
GAS SAFETY (INSTALLATION AND USE)
REGULATIONS 1998
It is the law, in GB, that all gas appliances must be installed by a
competent person in accordance with the above regulations. Failure
to install appliances correctly could lead to prosecution. It is in your
interest and that of safety to ensure compliance with the law. The
manufacturer’s notes must not be taken, in any way, as over-riding
statutory obligations.
In GB, a competent person is someone registered with CORGI.
All CORGI registered installers carry a CORGI ID card and have a regis-
tration number. Both should be recorded in the BENCHMARK check-
list. You can check that your installer is CORGI registered by calling
CORGI on 01256 372300.
WARNING: This appliance must be earthed and protected by a 3
amp fuse.
ELECTRICITY SUPPLY: 230V ~ 50Hz
IMPORTANT: To get the best from your Worcester CDi please read
these instructions carefully.
NOTE: In the event of a fault the appliance should not be used
until the fault has been corrected by a competent person.
BENCHMARK
The Benchmark initiative is a code of practice to encourage
the correct installation, commissioning and servicing of domestic cen-
tral heating boilers and system equipment.
A checklist can be found in the back of every installation
manual. This is a vital document that needs to be completed by the
installer at the time of installation. It confirms that the boiler has
been installed and commissioned according to the manufacturers
instructions.
In Eire the declaration found in IS 813 must be complet-
ed. Without completion of the checklist and/or declaration, manufac-
turers may refuse to respond to a call-out request. It is important that
the checklist and/or declaration are fully completed by your installer.
