pipes threaten to freeze. This is how to do it (see 5.7):

of the appliance by turning it clockwise as far as it
will go (a quarter turn).

Open all hot water taps connected to the gas instan-
taneous water heater so that the appliance and pipes
are fully drained.

Leave the hot water taps and the drain plug open
until refilling the heater after the danger of frost is
over.

When subsequently filling the gas instantane-
ous water heater, only start it up when water
comes out of the open hot water taps after
you open the shut-off valve on the cold water

connection of the appliance. This ensures
that the gas instantaneous water heater is
completely filled with water.

shown by the ignition voltage LED lighting up.
The battery compartment (1) is at the bottom of the
appliance on the left, and can be accessed without
