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-Fwill 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.

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.

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.

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.

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 CORGI registered installer or in IE a competent person.
