Replacement is necessary if the anode
has dissolved for more than 60%. If the
anode is not replaced in time, this may
negatively affect the life of the tank.
To replace, follow these steps:
1. Shut off the water tap in the cold-
water supply line.
2. Open up the nearest hot-water tap
so that the water pressure in the
boiler and pipeline drops.
3. Loosen the anode using a correct
spanner.
4. Check the anode and replace if
necessary.
5. Replace the anode in a water-tight
way. Attention: the anode should
be in contact with the tank (metal to
metal). If there is no contact
between anode and tank, for
example as a result of an applied
sealant, the anode will not be able
to fulfil its function.
2.8.2 Cleaning
1. Shut off the gas supply.
2. Slide the air-supply pipe into each
other so that it can be removed
(see Fig. 11).
3. Unscrew the 4 bolts (A) from the
aeration chamber lid and remove
these (see Fig. 12).
4. Remove the pilot-flame pipe and
thermocouple from the gas-control
block (see Fig. 13).
5. Remove the main burner from the
flexible burner-pipe connection.
This must be done from the
aeration chamber (see Fig. 13).
6. Now unscrew the 4 bolts (B) from
the aeration chamber and pull
these out a little (see Fig. 12). Make
sure not to damage or displace the
packing.
7. The burner-chamber guard can
now be removed (see Fig. 14).
Remove the whole aeration
chamber, together with the guard.
8. After removing the nut from the
back, the burner can be tilted out of
the guard (see Fig. 15). If
necessary, the burner can be
freed completely by removing the
