Check the pressure gauge; it must read between . Turn on the electrical power switch feeding the boiler.

When the boiler detects an operational anomaly, it cuts off the gas supply and flashes an error code on the LCD display. Error Code Cause Description Corrective Action Ignition failure or no flame detected Check gas supply valve; press Reset button. E02 Safety thermostat overheat limit reached Wait for boiler to cool down; check radiator valves. E03 Flue pressostat / Exhaust fan fault Check for flue blockages or fan electrical failure. E05 Heating circuit temperature sensor (NTC) fault Contact service technician to replace the sensor. E06 Domestic Hot Water (DHW) sensor fault Tap water sensor needs testing or replacement. E10 Low water pressure in the system Open the filling loop; raise pressure to 1.2 bar. 6. Routine Maintenance Requirements

The boiler water temperature has exceeded safe limits. Allow the boiler to cool down, then reset it. Ensure radiator valves are open. Flue Pressure Switch / Fan Fault

: Turn it to the snowflake icon to activate both radiators and hot water. Temperature Settings : Heating : Select a temperature between Hot Water : Select a temperature between

: Normal operating pressure typically sits between 1.5 and 1.8 bar when the system is hot; if it exceeds 2.5 bar, the pressure may be too high. Common Issues :

Use the radiator-symbol plus/minus keys to dial your ideal loop temperature (typically set between 35°C and 80°C depending on insulation type).

Inspect the copper fins annually and remove soot build-ups to maximize conductive thermal transfers into system water loops.

Avoid unverified third-party websites charging for manual downloads. The manual should be free.

The mounting brackets must be firmly anchored to a solid, load-bearing structure capable of supporting the boiler's 38 kg wet weight.
