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.

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.

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.

Important Notes

• This appliance must not be operated without the casing correctly fitted and forming an adequate seal.

• If the boiler is installed in a compartment then the compartment

MUST NOT be used for storage purposes.

• If the boiler is installed with a loft air grille and roof flue, the loft must not be used as a living space and care must be taken to ensure that the loft air grille is not blocked.

• If the appliance is fitted with a twin flue system using a loft air grille and both the boiler and grille are installed within a cupboard or compartment, then permanent air vents are required and care must be taken to ensure that the air vents are not blocked.

• Under NO circumstances should any of the sealed components on this appliance be used incorrectly or tampered with.

• If 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 CORGI registered installer or in IE a competent person.

Operation

In normal operation the control unit display (F) will show the codes:

O - Standby (no demand for heat)

C - CH or DHW being supplied

P - Boiler frost protection (boiler will fire when temperature is less than 3 o 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 CORGI registered installer or in IE a competent person.

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, including the domestic hot water supply.

To relight the boiler

Repeat the procedure detailed in 'To light the boiler'.

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 CORGI registered installer or in IE a competent person.

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 CORGI registered installer or in IE a competent person.

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 CORGI registered installer or in IE a competent person 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.

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.

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 CORGI registered installer or in IE a competent person.

POINTS FOR THE BOILER USER

Note. In line with our current warranty policy we would ask that you check through the following guide to identify any problems external to the boiler prior to requesting a service engineers visit. Should the problem be found to be other than with the appliance we reserve the right to levy a charge for the visit, or for any pre-arranged visit where access is not gained by the engineer.

TROUBLESHOOTING - TYPICAL NON PRODUCT FAULTS

Problem

Boiler is not working for central heating or hot water.

Boiler is not working for central heating or hot water but attempts to fire by going through 3 ignition attempts.

Boiler is not working for central heating or hot water and the display shows ‘L:A

(flashing).

Boiler is not working for central heating or hot water and the display shows ‘H:A

(flashing).

Solution

• 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 to repeat ignition sequence.

• Check gas supply (try another appliance – cooker/fire etc.) – If no gas supply then not a boiler fault – contact gas supplier.

• Check condensate pipe is not blocked or frozen. If blocked, clear blockage – if not possible to check 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.
