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.
2.10.1 Boiler with frost protection, during longer periods
of non-use
• Set the room thermostat to a low temperature, e.g. 10°C;
• S witch setting p4 to 1 (hot water pre-heat) will switch off
this 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.
2.10.2 Boiler without frost protection, during longer
periods of non-use
• T urn time clock off and allow system to cool down then iso-
late mains power supply at the fused spur unit.
• Isolate the gas supply at the boiler valve.

Drain the boiler and central heating system if you will not be
using the home for a long period and there is a chance of
night frost.
