icos HE

The new icos HE range complements the best selling

range

and extends the Ideal wall hung condensing boiler range to lower

outputs. The icos meets the needs of smaller properties and those

areas with lower heat loads. The range consists of two models with

outputs from 30 to 36kW, which may be installed in multiples if

required.

As with the

range, icos boilers provide high efficiencies of

98.7% nett (88.9% gross) non-condensing and over 108% nett

(97.3% gross) at 30% load. Even higher efficiencies are achieved at

lower system temperatures. The fully modulating gas/air design

ensures maximum efficiency is maintained down to 10.4kW output.

Naturally such performance exceeds the Seasonal Efficiency

requirements of the latest Building Regulations.

A robust monobloc cast aluminium heat exchanger provides a very

compact and system tolerant design with down firing fan assisted

burner, with condensate sump beneath. The pre mix burner design

ensures the lowest level of emissions achieving Class 5 NOx levels.

A wide range of flue options provides excellent siting flexibility with a

choice of concentric or twin pipe flues for longer runs. Both provide

a choice of horizontal and vertical terminal options. For the awkward

installations where flue pluming can be an issue from horizontal

flues, High Level Flue Outlet kits provide the answer.

The icos range is controlled by an advanced microprocessor system

ensuring correct operation of ignition, flame detection, temperature

and burner modulation. An easily read display provides full

commissioning and diagnostic display information.

The small size coupled with ease of installation and siting makes it

one of the simplest boiler ranges to install and service.

The Ideal

W wall mounted boiler comes in a range of outputs

45, 60, 80 or 100kW and all are capable of being installed as a

single unit or in simple modular formations for even bigger outputs.

The

W is a highly efficient fully condensing boiler - up to 98%

efficient nett (88.5% gross) non condensing and an impressive

108% nett (97.3% gross cv) at 30% load, fully condensing. Even

higher efficiencies are achieved at lower system temperatures. The

fully modulating gas/air design ensures that maximum efficiency is

maintained down to very low loads reflecting the needs of modern

systems. At its heart is a robust cast aluminium heat exchanger

providing a compact, space saving design making this the ideal

boiler for plant rooms where space is at a premium.

Ideal

boilers are fan assisted and have been designed with

siting flexibility in mind. Flues can be concentric, twin duct, room

sealed or open flued in single or multiple installations. It is one of

the easiest commercial boiler ranges to install and service.

The premix burner design ensures the lowest level of emissions. The

range has been approved to the most stringent European Standards

governing safety and performance of commercial boilers and is

classified as low NOx (Class 5).

The Ideal

W incorporates an advanced microprocessor based

control system which operates all electrical functions of the boiler

including ignition, flame detection, temperature control and burner

modulation. In addition the system has full commissioning and fault

diagnostic displays, and two remote indication contacts as standard.

The boilers are offered with an extensive range of option kits

including flues, system controls including BMS (0-10v) interface and

modular header kits for maximum flexibility and ease of

specification.

Conforms with all relevant
European standards and
requirements

modulation to low outputs for

high operating efficiencies

Customers increasingly demand higher efficiencies and lower emissions from the heating plant. All this must be achieved in ever smaller

dimensions. Ideal now provide a range of solutions with the high efficiency condensing icos HE and

wall hung boilers.

icos HE Boiler Construction

Ideal icos wall mounted boilers feature `monobloc' aluminium heat

exchangers.

The heat exchanger is mounted in a sealed white enamelled

steel casing.

A premix downfiring burner is mounted above the heat exchanger.

A cast aluminium sump is fitted below with condensate drain

connection.

The concentric flue outlet and air inlet is positioned on the boiler

top, with system connections at the top and gas connection at base.

Controls are immediately accessible at lower front. Maintenance

and servicing is all achieved from the boiler front.

icos HE Condensate Drain

Ideal icos boilers will produce condensate whenever the

temperature of the return water from the system is below

approximately 55°C (the dew point of the combustion products).

Natural Gas condensate is mildly acidic with a pH value of about

4 and therefore corrosion resistant materials must be used in the

construction of the condensate drain. Standard PVC pipe is suitable

for this purpose and should be connected to the plastic drain fitted

on the boiler.

A condensate trap is fitted to the boiler and the drain may be led

directly into the normal drainage system. The pipe should be

installed with an adequate slope (eg 1 in 50) and consideration

should be given to frost protection.

W Boiler Construction

Ideal

W wall mounted boilers are constructed from cast

aluminium heat exchangers with tubular steel flow and return manifolds.

The heat exchanger is mounted in a sealed white enamelled

steel casing.

A premix downfiring burner is mounted above the heat exchanger.

A cast aluminium sump is fitted below with condensate drain

connection.

The concentric flue outlet and air inlet is positioned on the

boiler top, with gas and system connections at the base.

Controls are accessible behind a drop down door. Maintenance

and servicing is all achieved from the boiler front.

W Condensate Drain

Ideal

W boilers will produce condensate whenever the

temperature of the return water from the system is below

approximately 55°C (the dew point of the combustion products).

Natural Gas condensate is mildly acidic with a pH value of about

4 and therefore corrosion resistant materials must be used in the

construction of the condensate drain. Standard PVC pipe is suitable

for this purpose and should be connected to the plastic drain fitted

on the boiler.

A condensate trap is supplied for fitting to the boiler and the

drain may be led directly into the normal drainage system. The pipe

should be installed with an adequate slope (eg 1 in 50) and

consideration should be given to frost protection.

W Flue Kits

W Only

The flue kits are suitable for use with the Ideal

boiler only.

These kits and the associated options are suitable for both roof

and wall mounting applications.

Several flue options are available:

· Horizontal flue kits (80/125mm or 100/150mm dia.)

· Vertical roof flue kits (80/125mm or 100/150mm dia.)

· Twin pipe flue kits (80mm dia.)

· Open flue kits

The twin pipe flue kit is suitable where particularly long flue

runs are required and compact flue and air ducts are required.

The roof kit is suitable for both flat and pitched roof termination,

using a concentric flue (tube within tube) to run vertically from the

top of the boiler and terminating above the roof level.

If obstructions prevent direct flue routing then both 90° and 45°

elbows can be provided to offset any of the flue systems.

Accessories

Flue duct extension kits are available for flue lengths extending

beyond 1 metre. These packs contain additional 1 metre ducts and

may be cut to the desired length.

Elbows, 90° and 45°, are also available.

Weatherproofing

Where the flue passes through the roof line an adequate seal

must be made. This can be achieved by using either:

· Flat weather collar 125mm or 150mm

· Pitched weather collar 125mm or 150mm

Additional information covering selection and installation can be

found within this guide.

Flue Systems

To ensure safe and satisfactory operation, the boiler must be

connected to a chimney system capable at all times of adequately

evacuating the combustion products (see performance data table on

pages 5 and 9 for approximate volumes).

The Ideal icos and

W boilers are suitable for use in both

room sealed and open flue fan assisted operation. Ideal icos boilers

are suitable for use in room sealed fan assisted installations,

including use of air supply from boiler house. Connections for

combustion air inlet and flue products discharge are located on the

top of the appliance.

The jacket of the Ideal icos and

condensing boilers are

constructed such that it forms an airtight seal. It is therefore

important that the jacket of the unit is fitted properly whilst the

boiler is in operation.

The boiler is suitable for use in either single or multiple flue

configurations and can be fitted with a wide variety of flue systems.

Horizontal flue runs MUST be inclined at 1.5° (icos) or 2.5°

(

) to the horizontal in order that any condensate formed can

be discharged through the boiler.

icos and

All joints or connections in the flue system must be impervious

to condensate leakage and also any low points in the flue system

should be drained using pipe of material resistant to condensate

corrosion.

The flue duct termination point must be positioned so that it will

not be affected by adverse wind conditions and be free from any

obstructions. Note: A vapour plume will be visible at the terminal.

Therefore where possible terminal positions which could cause

problems due to plumeing should be avoided.

The use of a fan on the boiler permits long flue runs however,

the resistance of bends etc will reduce the overall length. Full details

of the icos and

W flue sizes and resistances can be found on

page 16 of this booklet.

NO additional diverter, stabiliser, or draught break should be

installed in the chimney system without prior consultation with Ideal

Stelrad Group.

Flues and terminal positions should be designed with strict

regard to the requirements of BS 5440: Part 1, BS 6644, IGE

UP/10 and the Building Regulations Part J as appropriate. Particular

attention should be paid to these for multiple boiler installations and

if required, the Clean Air Act.

Several flue options are available:

· Horizontal flue kits (60/100mm dia.)

· Vertical roof flue kits (60/100mm dia.)

· Twin pipe flue kits (80mm dia.)

· High level flue outlet kits

The twin pipe flue kit is suitable where particularly long flue

runs are required and compact flue and air ducts are required.

A connector is used at the boiler outlet.

The roof kit is suitable for both flat and pitched roof termination,

using a concentric flue (tube within tube) to run vertically from the

top of the boiler and terminating above the roof level.

High level flue outlet kits allow the horizontal flue outlet to be

extended, external to the building upwards to provide a flue exit at

high level, overcoming plumeing problems.

If obstructions prevent direct flue routing then both 90° and 45°

elbows can be provided to offset any of the flue systems.

The maximum potential length for each flue type by boiler model

is shown in the table opposite, although allowances must be made

when elbows are used. The length to be subtracted for each elbow

used is also provided in the table below.

(1) An opening here means an openable element, such as an openable window, or a fixed opening such as an air vent. However, in addition, the outlet should not be nearer

than 150 mm (fanned draught) to an opening into the building fabric formed for the purpose of accommodating a built in element, such as a window frame.

The pressure available at the boiler outlet is sufficient to

overcome the resistance of considerable flue lengths. The maximum

straight length of concentric flue may be as long as 31.6 metres,

dependent on model. A twin duct arrangement can be up to 29

metres combined flue and air pipes, with small wall terminals.

The maximum potential length for each flue type by boiler model

is shown in the table, although allowances must be made when

elbows are used. The length to be subtracted for each elbow used is

also provided in the table below.

Water Treatment

Corrosion will always occur within a heating/hot water system to

a greater or lesser degree irrespective of water characteristics, unless

the initial fill water from the mains is treated. For these reasons Ideal

Boilers Solutions strongly recommends that when necessary the

system be thoroughly cleaned prior to the use of a stable inhibitor

which does not require continual topping up to combat the effects of

hardness, salts and corrosion on the heat exchanger and its

associated systems.

The Ideal icos HE

W boilers have an aluminium alloy heat

exchanger. Therefore it is important that if water treatment is used it

is suitable for the material of the heat exchanger. The ONLY water

treatments approved are `Fernox Copal' and `Sentinel X 100'.

Current suitability should be confirmed with the manufacturer direct:

Sentinel Performance Solutions, The Heath Business and Technical

Park, Runcorn, Cheshire Telephone: 0800 389 4670 or Fernox

Manufacturing Co. Ltd., Cookson Electronics, Forsyth Road,

Sheerwater, Woking, Surrey GU21 5RZ Telephone: 01799 521133

for technical information.

Any other treatment used will render the guarantee of Ideal

Stelrad Group for this product INVALID. The use of artificially

softened water is NOT permitted.

Gas

icos HE

Natural Gas models: If there is any doubt concerning the

capacity of the gas meter, available gas pressure, adequacy of

existing pipes or the size required for new service pipes, contact the

Gas Region for advice. Installation pipework should be fitted and

tested for gas soundness in accordance with BS 6891. The local Gas

Region must be consulted if a gas pressure booster is needed.

W 45, 60 & 80

Propane Gas models: Contact the local Propane Gas supplier at

the installation planning stage to ensure availability of an adequate

supply of gas. Installation pipes, cylinders and pressure regulators

should be fitted in accordance with BS 5482: 1. Bulk tank

installations must comply with the Home Office Codes of Practice for

the storage of LPG at fixed installations.

Ventilation

Open flued application

Safe, efficient, and trouble-free operation of conventionally flued

gas boilers is vitally dependent on the provision of an adequate

supply of fresh air to the room in which the appliance is installed.

Ventilation by grilles communicating directly with the outside air

is required at both high and low levels. The minimum free areas of

these grilles must be according to the scale below. The use of an

extractor fan in the same room as the boiler (or in an adjacent room

in communication) can, in certain conditions, adversely affect the

safe operation of the boiler. Where such a fan is already fitted, or if

an extractor fan is likely to be installed at a later date, then the

advice of the gas supplier should be obtained.

Open Systems

The system should be vented directly off the boiler flow pipe, as

close to the boiler as possible. The cold feed entry should be

inverted and MUST be positioned between the pump and the vent,

and not more than 150mm (6") away from the vent connection.

There should be a minimum height, 500mm (20") of open vent

above the cistern water level. The vertical distance between the

highest point of the system and the feed/expansion cistern water

level MUST not be less than 3 metres.

The information provided is based on the following assumptions:

The boiler is at the highest point of the circulation system.

Systems designed to raise above the flow tappings will, of course,

automatically require a minimum static head higher than shown.

The position of the open vent/safety pipe above the expansion

cistern water level is given as a guide only. The final position will

depend upon particular characteristics of the system. Pumping over

of water into the expansion cistern should be avoided.

Particular reference should be made to BS 6644: Section 2;

Subsection 11, Guidance note PM5 "Automatically controlled steam

and hot water boilers" published by the Health and Safety Executive

and Water Regulations Guide.

The information and guidance given below is not intended to

override any requirements of either of the above publications or the

requirements of the Local Authority, gas or water undertakings.

In general, commercial closed pressurised systems are provided

with either manual or automatic water make up.

In both instances it will be necessary to fit automatic controls

intended to protect the boiler circulating system and ancillary

equipment by shutting down the boiler plant if a potentially

hazardous situation should arise.

Examples of such situations are low water level and operating

pressure or excessive pressure within the system. Depending on

circumstances, controls will need to be either manual or automatic

reset. In the event of shut down, both visual and audible alarms may

be necessary.

Pressure vessels used must comply with BS 4814 and must

be sized on the basis of the total system volume and initial

charge pressure.

Initial minimum charge pressure should not be less than 0.5 bar

(7.2psi) and must take account of static head and specification of

the pressurising equipment. The maximum water temperatures

permissible at the point of minimum pressure in the system is

specified in Guidance Note PM5.

When make up water is not provided automatically it will be

necessary to fit controls which shut down the plant in the event of

the maximum system pressure approaching to within 0.35 bar (5psi)

of the safety valve setting.

Other British Standards applicable to commercial sealed

systems are:

Performance

The Ideal

range offers high operating efficiencies,

together with the lowest possible emissions, and is certified to

comply with the Gas Appliance Directive (90/396) and the Boiler

Efficiency Directive (92/42), the European Directives governing

safety and performance of gas boilers ensuring high quality

performance.

The design of the boiler ensures high efficiencies at both full

and part loads to meet the new `Building Regulations 2000'

conservation of fuel and power. Approved efficiencies are up to 98%

at 80°C flow based on net calorific value of fuel (88.5% gross) at full

load. At 30% part load the efficiencies exceed 108% net (97.3%

gross).

Electrical Controls

The boilers incorporate an advanced microprocessor based

control system which operates all electrical functions of the boiler

including ignition, flame detection, flow/return temperature sensors

and output modulation. In addition the microprocessor displays

boiler status and a fault diagnosis program.

Two remote indication contacts are provided as standard.

Boiler Operation

icos and

On a call for heat, air is drawn into the boiler variable speed fan.

The fan inlet incorporates a special mixing arrangement for gas

supplied from the gas valve. The gas/air mixture is automatically

ignited at low rate beneath the burner via a spark electrode and

ignition proved by a flame rectification electrode. The flue gases pass

downwards through the heat exchanger and via the sump and flue

outlet to atmosphere. A plume of vapour will be visible at the

terminal due to the low exit temperature.

The boiler modulates its output according to demand via the

flow/return sensors and any external controls. The fan speed and gas

flow are adjusted under this electronic control to provide the correct

mixture and output. This maintains high efficiency part loads.

Condensation within the boiler will start to occur when the

return temperature is below the dew point (55°C). The flue gases will

condense and increase boiler efficiency by giving up their latent heat

to the system. Condensation formed within the boiler is removed via

the integral drain.

In order to give you assurance and peace of mind a Certification of

Compliance to the Building Regulations 2006 can be obtained from

the commercial heating department.

product specification

System Design

The efficiency of this range of boilers is higher than conventional

boilers because of the increased heat exchange area.

At return temperatures of 55°C and below, the differences

become more marked because the water in the flue gases starts to

condense releasing its latent heat.

In general, the lower return temperature, the better the efficiency.

In new systems it is best to design for the lowest flow and return

temperatures that are practical (subject to the lower limit mentioned

above). For optimum operation it is advised that the system be

designed on a temperature differential of 20°C.

Installation

For safety, a competent CORGI (Council for the Registration of

Gas Installers) registered installer must fit this appliance. CORGI

requires its members to work to satisfactory standards.
