2icos system - User's
Introduction
The icos system is a wall mounted, room sealed, condensing
boiler, featuring full sequence automatic spark ignition and fan
assisted combustion.
Due to the high efficiency of the boiler, condensate is produced
from the flue gases and this is drained to a suitable disposal
point through the plastic waste pipe at the lower rear of the
boiler. A condensate 'plume' will also 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.

IS OFF.
2. Set the mains ON/OFF switch (A) to OFF and the thermostat
knob (F) 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 central heating, if required.
Note. In normal operation the control unit display (C) will show
the codes:
Standby - no demand for heat.
CH being supplied.
Boiler Frost Protection.
During ignition, the LED (E) will flash.
During normal running the LED (E) will remain illuminated.
Note.
If the boiler fails to light after 3 attempts the fault code L F will be
displayed.
Press the reset button (D) for 2 seconds then release. The
boiler will repeat the ignition sequence. If the boiler still fails to
light consult a Gas Safe Registered Engineer or in IE a
Registered Gas Installer (RGII).
Note.
The pump will operate briefly as a self-check, once every 24
hours regardless of system demand.
Note.
Boiler Frost Protection occurs when the temperature is less than
3 degrees. Then the boiler will fire.
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

BOILER CONTROLS
Control of water temperature
The boiler controls the central heating radiator temperature to a
maximum of 82oC, adjustable via the thermostat knob (F).
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, and switch the
electricity supply to OFF.
For longer periods the entire system should be drained.
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 re-light.
If the fault re-occurs, 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).
Loss of system water pressure
The gauge (H) indicates the central heating system pressure. If
the pressure is seen to fall below the original installation
pressure of 1-2 bar over a period of time then a water leak may
be indicated. In this event conduct the re-pressurising procedure
(see Trouble shooting problem 4). If unable to do so or if the
pressure continues to drop a Gas Safe Registered Engineer or
in IE a Registered Gas Installer (RGII) should be consulted.
DO NOT FIRE THE BOILER IF THE PRESSURE HAS
REDUCED TO ZERO FROM THE ORIGINAL SETTING.
Condensate Drain
The condensate drain (G) 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) should be sought.
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, wipe with a damp cloth
and finish off with a dry cloth.
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).

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.
