3.1.2

Putting into operation:

1. Check whether the device has been
filled with water and whether the gas
supply to the water heater is open;
2. Turn the temperature control knob
clockwise and place the control knob
in the 'PILOT'-position ( );
3. Remove the outer and inner door of
the combustion chamber.
4. Keep the control button pushed-in and
press the piezo-ignitor several times
until the pilot burns (see drawing 6);
5. Keep the control button ( ) pushed-
in for approximately 20 seconds.
After releasing the button the pilot
should remain burning. If the pilot
extinguishes you should wait 5
minutes before repeating the ignition
procedure;
6. Subsequently remount the inner and
outer door; see "Mounting the inside
door";
7. Turn the control button to the 'ON' ( )
position;
8. Place the temperature control button in
the correct position, preferably position
4 (approximately 60°C). The appliance
will now operate fully automatically;
3.1.3

use

The appliance is under water supply
pressure (with a maximum of 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 control
thermostat. The main burner will shut
down as soon as the water temperature
returns to the preset temperature.
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
Higher water temperatures will cause more
scale build up 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
22
at lower temperatures. 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.
3.1.4

Putting out of operation

1. For short periods of time the control
knob should be turned to ( ); the
pilot keeps burning;
2. For longer periods of time the knob
should be turned to the ( ) position;
the pilot is extinguished;
3. Close the gas tap in the supply
pipe. In case of longer interruptions
or in the event of risk of frost it is
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 airlocks).
To be able to drain the appliance
completely it should be disconnected
and tilted slightly in the direction of
the drain tap.

3.1.5 maintenance

The inlet combination has to be tested
regularly by relieving it (via the relief
button). The water has to flow out in a
forceful jet. Check whether the discharge
pipe is open.
We recommend a service agreement on
an annual basis.
To be able to order spare parts it is
important to note the type of appliance
as well as the serial number of the
appliance. Based on this information the
data concerning the spare parts can be
determined.
