INSTRUCTIONS
Frost protection
This is provided automatically by the boiler control unit. If frost is
likely during an absence from home, turn the boiler off at the time
switches ONLY, leaving the mains supply switched ON.
If the boiler flow temperature falls below 7
without the boiler firing, until the temperature exceeds 10
If the flow temperature falls below 3
o
temperature exceeds 10
C.
Fault condition
If the boiler will not light initially or if a fault develops during normal
operation, the first digit and the last 2 digits of the display will flash
alternately. In this event press the RESET button and the boiler
will recommence the ignition cycle.
If the fault condition persists, turn the boiler OFF and consult your
CORGI registered installer.
Loss of system water pressure
The gauge (E) on the control panel 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 consult your local registered installer.
DO NOT OPERATE THE BOILER IF THE PRESSURE HAS
REDUCED TO ZERO FROM THE ORIGINAL SETTING.
Escape of gas
Should a gas leak be suspected contact your local gas supplier
IMMEDIATELY.
Do NOT search for gas leaks with a naked flame.
Condensate drain
The condensate drain must NOT be modified or blocked.
Blockage 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 seek advice from your local
registered installer.
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
registered installer, local gas authority or registered service
organisation.
