is easily assembled on site.
Burners
The 3 burners are of stainless steel construction.
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 CXSD 40/H-120/H range of boilers has been tested
and certified by British Gas to prEN656 for use with Natural gas
only.
Multiple boiler installations
The Concord CXSD/H range is certificated for use in multiple
boiler installations, providing that the following conditions are
satisfied.
1. A downdraught thermostat kit MUST be fitted to ALL boilers
in the installation.
2. A maximum of 6 boilers may be used with a single flue
header.
3. For clearances see Frame 2.
A comprehensive guide to multiple installations of Concord
CXSD/H boilers is available.
WARNING. Failure to use a downdraught kit on every boiler in
a multiple boiler installation will negate the certification of the
installation and therefore contravene the essential requirements
of the Gas Appliance Directive.
Note. The CXSD 40/H, CXSD 50/H and CXSD 60/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.
