Other Shutdown Situations
Should a shutdown situation indicated on the display by the following letters and
figures occur, E04, E05, E06, E07, E08, E09, E20, E21, E33, E34 contact one
of our Authorised Service Centres.
If instead the display shows one of the shutdown situations indicated by the
following letters and figures, A77, A78, A97, A98, A99, try resetting the boiler by
pressing the reset button "D". If the boiler shuts off again, contact one of our
Authorised Service Centres.
The boiler is fitted with a device which, in the event that the water temperature falls below
8˚C the pump activates and runs until a temperature of 18˚C is attained. In the event that
the water temperature falls below 3˚C, the diverter valve switches to Domestic Hot Water
and the burner fires and runs on minimum power until a temperature of 33˚C is attained.
This device is only activated when the boiler is operating perfectly and
- the system pressure is sufficient;
- the boiler is powered electrically;
- gas is being distributed.
Schedule an annual maintenance check-up for the boiler with a CORGI registered
Service Engineer.
Correct maintenance always results in savings in the cost of running the system.
Our boilers are designed to function either with Natural Gas (methane) or L.P.G. gas. If
you need to changeover from one gas to the other, one of our Authorised Service Centres
should be contacted.
