recommended to also close the cold
water tap and to drain the appliance
after cooling (open the drain tap; it is
possible 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 40°C
Position 2 = approximately 50°C
Position 3 = approximately 60°C
Position 4 = approximately 70°C
Position 5 = approximately 80°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 90°C, also extinguishing the
pilot burner.
