2.8.1 Sacrificial 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.
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.
2.8 Maintenance
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.
