When decommissioning the boiler,
precautions should be taken to avoid frost

the boiler and the central heating system
are completely drained down.
33.1 General
The appliance combines a maximum of
comfort with extremely simple operation.
As a user you need to adjust nothing other
than the desired times and temperatures on
the room thermostat or programmer,
irrespective of the time of year.
Depending on the value that you choose as
being the most comfortable, together with
the lowest possible use of energy, the
following tips can help to make the optimum
use of your appliance:
In order to limit the energy used, it is
recommended that all radiator valves should
be of the thermostatic type and in the rooms
to be heated be adjusted to provide a
comfortable temperature.
Close the radiator valves in rooms where
you require no heating.
Set the room thermostat to a lower
temperature some time before you retire to
bed.
For more information, please consult your
installer.
33.2 Holiday
Also during long-term absence, for example
in the holiday period, it is recommended that
you leave the appliance switched on.
Every 24 hours the appliance performs a
number of checks.
If the occurrence of frost can be excluded,
you should adjust the room thermostat to a
low temperature.
If the occurrence of frost cannot be
excluded, you should adjust the room
thermostat to a temperature of 12 °C or
higher.
Although the appliance is provided with
internal frost protection this does not
protect the rest of the installation against
freezing.
NEVER isolate the mains and NEVER close
the gas tap.
33.3 Cleaning
Wipe the outside of the appliance regularly
with a soft, damp cloth. For this it is not
necessary to close the gas tap or to switch
off the electricity supply.
Never use aggressive or flammable
cleaning materials.
Remember that the pipes can reach high
temperatures.
