Current Gas Safety (Installation and Use)
Regulations or rules in force
It is the law that all gas appliances are installed and serviced by a
CORGI registered installer in accordance with the above regulations.
Failure to install appliances correctly could lead to prosecution. It
is in your own interest, and that of safety, to ensure that the law is
complied with.
The Concord CXDi 110/H-180/H range of boilers has been tested
and certified by British Gas to prEN656 for use with natural gas only.
Note.
Concord CXDi 110/H - 180/H boilers are intended for use as
COMMERCIAL BOILERS and are NOT certified for use in domestic
applications. A domestic installation is defined as an installation
where the boiler takes its combustion air from a living space or from
a room directly or indirectly connected with the living space. It is
important, therefore, that no external control devices - e.g. flue
dampers, economisers etc., are directly connected to this appliance
unless covered by these Installation and Servicing Instructions or
otherwise recommended by Caradon Ideal Limited in writing. If in
doubt please enquire.
Any direct connection of a control device not approved by Caradon
Ideal Limited could invalidate the British Gas Certification, the
normal appliance warranty and could also infringe the Gas Safety
Regulations. Table 1, Table 2 and the descriptive notes which follow
contain all the essential data likely to be required by the installer.
GAS CONTROLS
The gas controls consist of a high / low arrangement with direct
burner ignition.
ELECTRICAL CONTROLS
WARNING
isolate the boiler.
The Concord CXDi/H incorporates an advanced microprocessor-
based control system which operates all electrical functions of the
boiler, including ignition, flame detection, thermostatic control and
high/low operation. In addition, the microprocessor has onboard
servicing and commissioning instructions and a fault diagnosis
programme.
The illuminated LED display gives a continual read-out of the
boiler status and functions but, in the (unlikely) event of a fault
condition, will display the fault areas.
