Putting out of operation
For a short period:
1. Turn back the control knob to ‘PILOT
FLAME’ (
X
); the pilot flame will
continue to burn. The main burner
cannot ignite.
For a longer period:
1. Turn the control knob to ‘OFF’ (
●
);
the pilot flame will go out.
2. Shut the gas valve in the supply
pipe. In case of very long intervals,
in combination with a risk of frost, it
is recommended to also shut off the
cold-water supply and to drain the
cooled-down device by opening the
drain valve – a drain hose may be
connected to it – and opening the
nearest hot-water tap for aeration.

Temperature regulation
The appliance is under water supply
pressure (maximum 8 bar). The amount
of cold water that is added is equal to
the amount of hot water used. The gas
control block automatically regulates the
gas supply. The main burner will ignite
as soon as a reduction in water
temperature is sensed by the thermo-
stat. The main burner will shut down as
soon as the preset temperature is
achieved.
Position 1 = approximately 30°C
Position 2 = approximately 40°C
Position 3 = approximately 50°C
Position 4 = approximately 60°C
Position 5 = approximately 70°C
At high water temperatures there is
more scale buildup in the appliance. It is
for this reason that it is recommended to
place the temperature control knob in
position 4 as the accumulation of scale
will be reduced. In addition a safety
thermostat has been fitted. This
thermostat completely shuts off the gas
supply if the water temperature
reaches 82°C, also extinguishing the
pilot burner.
