wall mounted 03-07

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 boilers are also designed for multiple boiler installations.

Such installations can be an advantage in many situations:

· Compact size means easier location, transportation and

handling.

· Close load matching means higher annual operating

efficiencies.

· Inherent reliability and service continuity. One boiler may be

shut down for servicing whilst the remainder continue

operating.

· A sequencer kit and multiple boiler pipework kits are available

for the

The header kit comes complete with all the components

necessary to complete a multiple installation:

· Gas and water headers (2 or 3 boilers)

· Mixing header

· Individual flow, return and gas connection pipework

incorporating isolating valves

· All necessary mounting brackets for pipework

Ideal

W boilers are also designed for use with a boiler

frame mounting kit which allows boilers to be mounted onto a free

standing boiler frame rather than onto the wall.

This frame mounting kit is especially useful when wall space is

at a premium or wall condition is suspect. The frame mounting kit is

suitable for use with installations of 1 or more boilers.

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.

flueing

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
