2.8.3 Decalcification
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.

should be checked.
Safety thermostat
All appliances have been fitted with
a safety thermostat that shuts off the
gas supply when the water
temperature is too high. The safety
thermostat remains activated until the
water temperature drops below the
safety temperature. The water heater
must be reignited manually. The
regulation thermostat should be set to a
lower water temperature. If the pilot is
extinguished repeatedly at higher
temperatures than normal, this indicates
that the safety thermostat is operating.
