Gas Safety (Installation and Use) Regulations,
1994, amendments 1996 or rules in force.
It is the law that all gas appliances are installed and serviced by a
CORGI registered installer (identified by ) 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 CXi 110-180 range of boilers has been tested and
certified by British Gas to prEN656 for use with natural gas only.
Note.
Concord CXi 110 - 180 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 Plumbing
Limited in writing. If in doubt please enquire.
Any direct connection of a control device not approved by Caradon
Plumbing 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
. The ON/STANDBY [1/0] button does NOT electrically
isolate the boiler.
The Concord CXi 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.
