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.

2.8.2Cleaning

1.Close the gas supply and demount the burner after it has cooled down;

2.Disconnect the burner, pilot pipe and thermo couple from the gas control block (see drawing 11);

3.Remove the complete burner assembly;

4.Clean the burner with a soft brush;

5.Check the pilot burner and clean it if so required;

6.Check the combustion chamber, flue tube and flue baffle and clean these if required;

7.Re-mount in reverse order. Tighten the thermo couple connection on the gas control block hand tight and tighten it further with a wrench to a maximum of 1/4 turn as it only needs to make contact.

After cleaning of the pilot- and main

burner the operation of these should be checked. If necessary the burner pressure of the main burner should be reset.
