Start-up/shutdown
Shutting down the heating system

Without frost protection (shutdown)

Shut down your heating system com-
pletely if it will not be needed for long
periods of time (several months).
We recommend you contact your local
heating contractor if you are planning to
take your heating system out of use for
long periods. Your heating contractor
can then take any necessary action, sub-
ject to requirements, e.g. frost protection
or preserving the heating surfaces.
1. Close the gas shut-off valve and safe-
guard against unauthorised reopen-
ing.
2. Turn off the ON/OFF switch.
The power to the system is now
switched off.
Note that the system is no longer
frost-protected.
