INTRODUCTION

CONSTRUCTION

Concord ESi boilers are sectional cast iron boilers, with an
atmospheric two-stage gas burner and electronic ignition via an
ignition burner.    The heat output is adjustable to 85% of full
output. The combustion chamber and draught diverter are sheet
steel.  They are designed for use with a hot water central heating
system, and have a heat output range of:  119 - 380 kW

They must be connected to a chimney.  The heat exchanger can
be supplied, assembled, or unassembled for site assembly.
They are suitable for natural gas only.

CERTIFICATION  EC:

The Concord ESi boilers meet the requirements of the following
European directives and are tested according to EN 656:

-

90.396 EEC Gas Appliances Directive

-

92.42 EEC Boiler Efficiency Directive

-

73.23 EEC Low Voltage Directive

Relevant standard: EN 60.335.1

-

89.336 EC Electromagnetic Compatibility Directive Relevant
standards: EN 50.081.1 / EN 50.082.1 / EN 55.014.

The boilers are of the B11 type.

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.

Note.

 

Concord ESi 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  
Ideal Stelrad Group
in writing. If in doubt, please enquire.

Any direct connection of a control device not approved by Ideal
Stelrad Group 
could invalidate the Certification, the normal
appliance warranty and could also infringe the Gas Safety
Regulations. Table 1 and 2 and the descriptive notes which follow
contain all the essential data likely to be required by the installer.

CAUTION.

To avoid the possibility of injury during the installation, servicing or cleaning of

this appliance care should be taken when handling edges of sheet steel components.
