GENERAL
INFORMATION
GAS SAFETY (INSTALLATION AND USE)
REGULATIONS
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
registration number. Both should be recorded in the BENCHMARK
checklist. 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 to BS 1362.
ELECTRICITY SUPPLY: 230V ~ 50Hz
IMPORTANT: To get the best from your Worcester Si II appliance
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 central
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 completed.
Without completion of the checklist and/or declaration,
manufacturers may refuse to respond to a call-out request. It is
important that the checklist and/or declaration are fully completed by
your installer.
