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.

of non-use

Set the room thermostat or other controls to a low tempera-

ture, e.g. 10°C,

central heating system from freezing.

periods of non-use

late mains power supply at the fused spur unit
