Frost hazard
Destruction of the device through freezing water
Store the device that has not been completely drained
of water in a frost-free place.
In the case of devices that are connected to a chimney,
the ingress of cold air must be taken into account.
ATTENTION
Cold air entering through the chimney
Risk of damage
When the exterior temperatures are below 0 °C, discon-
nect the device from the chimney.
1. Shut down the device if frost-free storage is not pos-
sible.
Shutting down
For longer breaks in operation or when frost-free stor-
age is not possible:
1. Drain the water.
2. Flush the device with antifreeze.
Draining the water
1. Unscrew the water supply hose and the high-pres-
sure hose.
2. Unscrew the supply line at the boiler base and allow

manufacturer.
1. Flush the device (burner off) completely with a com-
mercially available antifreeze.
This also provides a certain degree of corrosion protec-
tion.
