INTRODUCTION
CONSTRUCTION
BOILER BODY
The sectional boiler body is of cast iron and is supplied assembled
on a sheet steel combustion chamber with an integral draught
diverter. The boiler can be supplied in sectioned form to special
order for site assembly - refer to the section headed ‘Instructions
for Site Assembled Boilers’.
CASING
The casing is manufactured in stove enamelled sheet steel and
is easily assembled on site.
BURNERS
The 3 burners are of stainless steel construction.
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 CXS 40-120
range of boilers has been tested and
certified by British Gas to prEN656 for use with
Natural gas only.
Multiple boiler installations
The
Concord CXS 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 CXS
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
CXS 40,
CXS 50 and CXS 60
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.
