pilot flame from the bracket.
9. Clean the main burner with a soft
brush.
10. Check the pilot-flame burner and
clean if necessary.
11. Check the burner chamber, flue-
gas duct, and vortex strip and
clean if necessary.
12. Replace in reverse order.
Hand-tighten the thermocouple
connection on the gas-control
block and tighten with a spanner
for a further 1/4 turn at the most –
it only has to make contact. After
cleaning, check the operation of
the pilot-flame burner and the main
burner. If necessary, adjust the
burner pressure of the main
burner.
2.8.3 Descalcification
Formation of lime scale depends on the
quality and quantity of the water used.
In addition higher water temperatures
lead to more deposit in the appliance. A
temperature setting of 60°C is
recommended in order to keep the
calcification at a low level.
Decalcification should be attempted with
the proper means. For extensive
information a decalcification instruction
is available.
2.8.4 Spare parts
To be able to order spare parts it is
important to note the type of appliance
as well as the serial number of the
appliance. Based on this information the
data concerning the spare parts can be
determined.
2.9 Inlet combination
Not applicable in U.K. and Ireland.
2.10 Troubleshooting
In case of a failure, check the following
points before calling in a fault-clearing
service:
2.10.1 Safety thermostat
All devices are equipped with a safety
thermostat, which shuts off the gas
supply in case of too high a water
temperature. The safety thermostat will
remain switched on until the water
temperature has dropped to below the
safe temperature level. After that, the
device should be put back into
operation, because the main burner
and pilot-flame burner will have
extinguished as a safety precaution.
Next, adjust the control thermostat to a
lower water temperature. If the pilot
flame is repeatedly extinguished, at
higher water temperatures than
normal, this demonstrates that the
safety thermostat is switched on.
2.10.2 Hot-water temperature is
not correct
1. Check the settings of the
temperature-control knob.
2. Make sure the pilot flame is lit. If
necessary, light it (see ‘Putting into
operation’).
3. Check for leaks or taps that are left
running.
4. Have your installer or power
company check to make sure there
is sufficient gas supply and
pressure. A load that is insufficient
will cause water temperatures that
are too low.
5. Perhaps the hot-water
consumption is greater than was
calculated earlier.
6. Check to make sure the cold-water
inlet pipe is correctly positioned.
2.10.3 Hot water temperature too
high
Check whether the control thermostat is
set too high.
2.10.4 Possible water leakage
1. Check whether the drain tap is fully
closed.
2. Check whether all water
connections are water tight.
3. Check whether the possible water
leakage could be caused by
condensation.
