Commissioning, Filling the water heater

2.2Commissioning

2.2.1Filling 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 taps.

2.2.2Putting into operation

1.Check whether the water-heater 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 knob pushed-in and press the piezo-ignitor several times until the pilot burns (see Figure 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. The size of the pilot flame can be adjusted (see also “Pilot adjustment”).

6.Subsequently remount the outer and inner door; see “Mounting the inside door”.

7.Turn the control button to the ‘ON’ ( ) position.

8.Check the burner pressure setting (see Fig. 9) and adjust if required based on the technical information (see section 1.4).

9.Place the temperature control button in the correct position, preferably position 4 (approximately 60°C). The appliance will now operate fully automatically.
