Figure 10 - Conversion to another gas

4b. Conversion from LP-gas to natural gas:

-Put the pressure regulator into operation. To do this the temperature regulating knob should be pulled straight forward. Next the red plastic cover that is now visible, should be removed. Turn the ‘no pr’ (no pressure regulation) screw completely up (see Figure 10).

-Seal this setting with lacquer.

-Remount the burner in reverse order.

-Open the main gas tap.

-Set the correct burner pressure (see table above).

5.If necessary adjust the pilot correctly (see “Pilot adjustment”).

6.Fit the correct sticker from the conversion set on the appliance so that it is clear that the appliance has been converted and on which gas the appliance operates.

2.8Maintenance

To ensure safe and efficient operation of the water heater it is recommended that it is cleaned and serviced at least once a year by a qualified competent person.

2.8.1Sacrificial anode

The life cycle of the anode is determined by the quality and the quantity of the water flowing through the apparatus. It is therefore recommended that the anode be inspected and replaced if necessary at least once a year.

1.Close the stop cock in the cold water supply pipe,

2.Open the nearest hot water tap in order to allow the pressure to drop from the water heater and the pipes,

3.Slacken the anode with a fitting wrench,

4.Check the anode and replace it if it has been reduced in diameter by 60% or more at any point on its length,

5.Check for water leaks.

If it is necessary to replace the anode it should always be replaced by one of the same type.

The type of anode required can be determined on the basis of the type of the appliance and the serial number.
