3. Close the gas tap in the supply pipe.
In case of longer interruptions or in
the event of risk of frost it is recom
-
mended to also close the cold water
tap and to drain the appliance after
cooling (open the drain tap; it is pos
-
sible to connect a drain hose to the
drain tap; open the nearest hot water
drain point to prevent air locks).
To be able to drain the appliance
completely it should be disconnected
and tilted slightly in the direction of
the drain tap.
2.5 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
thermostat. 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 ther
-
mostat has been fitted. This thermostat
completely shuts off the gas supply if the
water temperature reaches 82°C, also
extinguishing the pilot burner.
