Gas Safety Regulations; Option Kits - IDEAL EVOMOD 250 Installation And Servicing

INTRODUCTION
boilers are fully automatically controlled, floor
The
standing, fanned, super efficient condensing appliances.
The EVOMOD 250 comprises of a single module capable of
delivering 250kW.
The EVOMOD 500 comprises two modules (master and slave)
stacked vertically and capable of delivering 500kW.
The EVOMOD 750 comprises three modules stacked vertically
(central master module, upper & lower slave modules).
The EVOMOD 1000 comprises two 500 modules side by side (the
slave module must be positioned to the left of the master module).
The comprehensive boiler controls built into the appliance include:
- 0-10V Boiler control input
- Volt free 'alarm' contacts (lockout)
- Volt free 'boiler run' contacts
- Burner hours run meters
- System temperature indication
The boilers can draw their combustion air from the room or via
ducting from outside.
Each module provides a maximum of 250kW heat output and will
modulate down to 50kW under the influence of controls.
(See Table 1, Page 2 for outputs at different temperatures).
Boilers comprising more than one module will share the heating
load equally among the boiler modules, switching the modules off
individually once the heating load drops below 20% of the total
boiler capacity. In this way a decreasing load is continuously
matched for optimum efficiency. The minimum output from all
models is 50kW, providing a turndown ration of 5:1 for the 250,
10:1 for the 500, 15:1 for the 750 and 20:1 for the 1000. Modules
will fire on the basis of least hours run.
Each module includes a flap which is only opened under air
pressure from the module fan. It thus prevents energy wastage
through non-firing modules.
Through a sophisticated control system combined with premix
burner technology and a stainless steel heat exchanger, the boilers
are capable of high operating efficiencies and low emissions (see
Table 1).
These boilers are certified to meet the requirements of the EC
Gas Appliance Directive, Boiler Efficiency Directive, EMC and Low
Voltage Directive.

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 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
4
GENERAL
Regulations, The Building Regulations (Scotland), Building
Regulations (Northern Ireland).
• The Water Fittings Regulations or Water byelaws in Scotland.
• The Current I.E.E. Wiring Regulations.
Where no specific 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.820:2000 "Non Domestic Gas Installations", the current
Building Regulations and reference should be made to the current
ETCI rules for electrical installation.
The boilers have been tested by BSI and conform to EN656,
EN13856 and EN15417 for use with Natural Gas.
Detailed recommendations are contained in the following
Standards and Codes of Practice:

SAFE HANDLING
This boiler may require 2 or more operatives to move it to its installation
site, remove it from its packaging base (see Frame 13) and during
movement into its installation location. Manoeuvring the boiler may
include the use of a pallet truck and involve lifting, pushing and pulling.
Caution should be exercised during these operations.
Operatives should be knowledgeable in handling techniques when
performing these tasks and the following precautions should be
considered:
• Grip the boiler at the base.
• Be physically capable.
• Use personal protective equipment as appropriate, e.g. gloves,
safety footwear.
During all manoeuvres and handling actions, every attempt should
be made to ensure the following unless unavoidable and/or the
weight is light.
• Keep back straight.
• Avoid twisting at the waist.
• Avoid upper body/top heavy bending.
• Always grip with the palm of the hand.
• Use designated hand holds.
• Keep load as close to the body as possible.
• Always use assistance if required.
SAFE HANDLING OF SUBSTANCES
No asbestos, mercury or CFCs are included in any part of the
boiler or its manufacture.
