2.8.3Decalcification
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.
2.8.4Spare parts

2.10 Fault finding
In case of failure the following 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.
