3.FOR THE USER
3.1Commissioning
Warning
Installing and commissioning of this water heater should only be carried out by a qualified competent heating engineer.
Filling the water heater
1.Close the drain tap.
2.Open the cold water tap to the water heater and open all taps where hot water can be drained for de- aeration. The water heater is filled as soon as cold water flows from all taps.
3.Close all hot water drain taps.
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
3.Remove the outer door of the combustion chamber.
4.Keep the control button
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.Fit the outer 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.
3.2Use
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 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.
3.3Putting 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.
