Shutdown
Shutting down the heating system for an extended period
You can switch your heating system off if you do not
intend to use it. We recommend you contact your heat-
ing contractor before and after shutting down for longer
periods.
Your heating contractor can then take suitable steps,
such as frost protection for the system or heating sur-
face preservation, as required.
Shutdown
1. Note
Only isolate the boiler from the power supply briefly
for maintenance.
The Lambda probe will otherwise not be heated
■
and could be damaged if the system is shut
down for a longer period.
■
The boiler circuit pump is switched on briefly at
regular intervals.
2. Remove encrustation from the hopper and boiler
cladding with a spatula or a flat scraper.
3. Perform all work described in the overview of chap-
ter "Maintenance and repairs" on page 45.
4. When there is a risk of frost, drain the boiler,
observing the instructions issued by your heating
system installer or ask them to charge the system
with antifreeze.

Note
No special measures are required when shutting down
the system on a temporary basis.
