2.11 Putting the boiler out of operation
The boiler must be switched off and allowed to cool down
before any maintenance or repairs are carried out. If the cen-
tral heating system is not going to be used for a long time
(during the holidays, for instance, or frost-free periods) it is
advisable to put the boiler out of operation.
2.11.1 Boiler with frost protection, during longer periods
of non-use
•
Set the room thermostat or other controls to a low tempera-
ture, e.g. 10°C,
•
Switch setting

to

(Eco mode), this will switch off
the heat retention function.
Now the boiler will only start working to protect itself against
freezing.
With external frost protection, the boiler can also prevent the
central heating system from freezing.
2.11.2 Boiler without frost protection, during longer
periods of non-use
•
Turn time clock off and allow system to cool down then iso-
late mains power supply at the fused spur unit
•

using the home for a long period and there is a chance of
night frost.
