Introduction
The icos is a wall mounted, room sealed, super efficient
condensing boiler featuring full sequence automatic spark
ignition and fan assisted combustion.
Due to the very high efficiency, condensate is produced from
the flue gases and this is drained to a suitable disposal point
through the plastic waste pipe at the right lower rear of the
boiler. A condensate 'plume' will also often be visible at the
flue terminal.
Safety
Current Gas Safety (Installation & Use)
Regulations or rules in force.
In your own interest, and that of safety, it is the law that this boiler
must be installed by a Gas Safe Registered Engineer.
In IE the installation must be carried out by a Registered Gas
Installer (RGII) and installed in accordance with the current
edition of I.S. 813 “domestic Gas Installations”, the current
Building Regulations and reference should be made to the
current ETCI rules for electrical installation.
It is essential that the instructions in this booklet are strictly
followed, for safe and economical operation of the boiler.
Electricity Supply
The appliance must be earthed.
Supply 230 V - 50 Hz. The fusing should be 3A.
This appliance is intended to be connected to the supply via a
double-pole switch, having a 3mm contact separation in both
poles, serving only the boiler and system controls. Alternatively, a
3-pin UNSWITCHED socket may be used.
Important Notes
zThis appliance must not be operated without
the casing correctly fitted and forming an adequate seal.
zIf the boiler is installed in a compartment then the compartment
MUST NOT be used for storage purposes.
zUnder NO circumstances should any of the sealed components
on this appliance be used incorrectly or tampered with.
zIf it is known or suspected that a fault exists on the boiler
then it MUST NOT BE USED until the fault has been
corrected by a Gas Safe Registered Enginner or in IE a
Registered Gas Installer (RGII).
zThis appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless
they have been given supervision or instructions concerning

zChildren should be supervised to ensure that they do not play
with the appliance.
In cases of repeated or continuous shutdown a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII)
should be called to investigate and rectify the condition causing
this and carry out an operational test after each intervention on
the device. Only the manufacturers original parts should be used
for replacement.
Minimum Clearances
Clearances of 165mm (6 1/2") above, 100mm (4") below, 5mm
(1/4") at the sides and 450mm (17 3/4") at the front of the boiler
casing must be allowed for servicing.
The minimum front and bottom clearance allowed when built into
a cupboard is 5mm.
To light the boiler (Refer to Frame 1)
1. CHECK THAT THE ELECTRICITY SUPPLY TO THE BOILER
IS OFF.
2. Set the mains on/off switch (A) to off and the CH thermostat
knob (C) to maximum.
3. Switch on the electricity supply to the boiler and check that all
external controls, e.g. programmer, room thermostat, etc are on.
4. Set the mains on/off switch to ON.
The boiler will commence the ignition sequence, supplying heat
to the system when required.
Operation
In normal operation the control unit display (F) will show the
codes:
- Standby (no demand for heat)
- CH or DHW being supplied
- Boiler Frost Protection (Boiler will fire if temperature is less
than 3 degrees C.
During ignition the LED (E) will flash.
During normal running the LED will remain illuminated.
Note. If the boiler fails to light after 3 attempts the fault code 'L' 'F'
will be displayed.
Press and hold the reset button for 2 seconds then release. The
boiler will repeat the ignition sequence. If the boiler fails to light
consult a Gas Safe Registered Engineer or in IE a Registerd Gas
Installer (RGII).
All Gas Safe Registered Engineers carry a Gas Safe Register ID card, and have a registration number. Both should be recorded
in the Benchmark Commissioning Checklist. You can check your installer by calling Gas Safe Register direct on 0800 4085500
THE BENCHMARK SERVICE INTERVAL RECORD MUST BE COMPLETED AFTER EACH SERVICE
Ideal Stelrad Group is a member of the Benchmark scheme and fully supports the aims of
the programme. Benchmark has been introduced to improve the standards of installation and
commissioning of central heating systems in the UK and to encourage the regular servicing of
all central heating systems to ensure safety and efficiency.

Control of water temperature
The boiler controls the central heating radiator temperature to a
maximum of 820C, adjustable via the CH thermostat knob (C).
Approx CH flow temperatures for the boiler thermostat settings
are:
Knob Setting Flow Temperature
o Co F
Minimum 30 86
Maximum 82 180
To shut down the boiler
1. For short periods
Set the mains on/off switch (A) to OFF.
2. For longer periods
Set the mains on/off switch (A) to OFF. Switch the electricity
supply to OFF. For longer periods the entire system should be
drained, inlcuding the domestic hot water supply.
To relight the boiler
Repeat the procedure detailed in 'To light the boiler'.
Frost Protection
If no frost protection is provided and frost is likely during a short
absence from home leave the heating controls (if fitted) at a
reduced temperature setting.
For longer periods the entire system should be drained.
If the system includes a frost thermostat then,during cold
weather, the boiler should be turned OFF at the time switch (if
fitted) ONLY. The mains supply should be left switched ON, with
the boiler thermostat left in the normal running position.
Boiler Overheat Thermostat
This thermostat will shut down the boiler in the event of
overheating. Should this occur a fault code 'L' 'A' will be
displayed. Press the reset button (D) and the boiler will relight.
If the fault recurs turn off the boiler and consult a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII).
Flame failure
Should this occur a fault code L-F will be displayed. Press the
reset button and the boiler will relight. If the fault recurs, turn off
the boiler and consult a Gas Safe Registered Engineer or in IE a
Registered Gas Installer (RGII).
Condensate Drain
The condensate drain must not be modified or blocked.
Blockage of the condensate drain, caused by debris or freezing,
can cause automatic shutdown of the boiler.
If freezing is suspected and the pipe run is accessible an attempt
may be made to free the obstruction by pouring hot water over the
exposed pipe and clearing any blockage from the end of the pipe.
If this fails to remedy the problem the assistance of a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII).
Escape of gas
Should a gas leak or fault be suspected contact your local gas
supplier without delay.
Do NOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains use a damp cloth and mild
detergent.
DO NOT use abrasive cleaning materials.
Maintenance
The appliance should be serviced at least once a year by a Gas
Safe Registered Engineer or in IE a Registered Gas Installer (RGII).
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.

by the engineer.
TROUBLESHOOTING - TYPICAL NON PRODUCT FAULTS
Problem Solution
Boiler is not working for
central heating or hot water.
• Check there is power to the boiler – switch (A) in the ON position and ‘ 0 ’ displayed on the
controls.
• If ‘
0 ’ not displayed then not a boiler fault – contact your installer/service company.
• Check external programmer is set to an ‘ON’ period and the relevant function selected i.e.
central heating or domestic hot water. Test by overriding the programmer by setting to
‘continuous.
• Check room thermostat for central heating or the cylinder thermostat for domestic hot water,
are set at the required temperature. To test operation of either thermostat turn fully up. If no
response contact your installer.

• Press reset button (D) for 2 seconds, the boiler should then re-light. If fault recurs this
indicates an overheat condition. The boiler should be turned off and your installer contacted.
• Check if ALL radiators have thermostatic radiator valves fitted. If they have contact your
installer.
