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
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.
Flame failure
Should this occur a fault code
will be displayed.
Press the rest button (D) and the boiler will relight.
If the fault recurs, turns off the boiler and consult a CORGI
registered installer.
Loss of system water pressure
The gauge (see illustration below) 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 is indicated. In this event a CORGI registered
installer should be consulted.
DO NOT FIRE THE BOILER IF THE PRESSURE HAS
REDUCED TO ZERO FROM THE ORIGINAL SETTING.
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 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
CORGI registered installer.
