1 GENERAL
1.1 INTRODUCTION
The boilers are fully automatically controlled, wall mounted,
fanned, super efcient condensing appliances.
The condensing boilers can be installed either on the wall or into
a prefabricated oor mounted frame.
The boilers are suitable for use with a room sealed ue or open
ue application.
Through a sophisticated control system combined with premix
burner arrangement the boilers are capable of high seasonal
efciencies of >96% and low emissions.
These boilers are tted with an integral ue non-return valve
which negates the tting of same in shared ue (B23) systems.
These boilers are certied to meet the requirements of the EC
Gas Appliance Directive, Boiler Efciency Directive, EMC and
Low Voltage Directive.
Note. These boilers cannot be used on systems that include
gravity circulation.
The boiler are suitable for connection to fully pumped, open
vented or sealed water systems. Adequate arrangements for
completely draining the system by provision of drain cocks MUST
be provided in the installation pipework.

1.3 SAFETY
Current Gas Safety (Installation and Use) Regulations
or rules in force
The appliance is suitable only for installation in GB and IE and
should be installed in accordance with the rules in force.
In GB, the installation must be carried out by a suitably qualied
Gas Safe registered engineer or in IE by a competent person. It
must be carried out in accordance with the relevant requirements
of the:
• Gas Safety (Installation and Use) Regulations
• The appropriate Building Regulations either The Building
Regulations, The Building Regulations (Scotland), Building
Regulations (Northern Ireland).
• The Water Fittings Regulations or Water byelaws in Scotland.
• The Current I.E.T. Wiring Regulations.
Where no specic instructions are given, reference should be
made to the relevant British Standard Code of Practice.
In IE, the installation must be carried out by a Competent Person and
installed in accordance with the current edition of I.S.813 “Domestic
Gas Installations” or I.S. 820 “Non-Domestic Gas Installations” as
appropriate, the current Building Regulations and reference should
be made to the current ETCI rules for electrical installation
.
