Romania - Tunisia - Algeria - Cyprus - Czech Republic
Maximum operating pressure: 6 bar
Maximum operating temperature: 100 °C
Boiler thermostat setting: 30 to 90°C
Safety thermostat setting: 110 °C
*Maintenance consumption: total heat emission when the burner is
off as a percentage of the nominal input power when the difference
between the mean boiler temperature and the room temperature is
30 K - in accordance with DIN 4702 - EN 303.
