2 Hazard information
Please read these operating instructions carefully!
Failure to follow the instructions and advice could cause damage to the appliance and personal injury.
Main switch RISK
Never stop the boiler using the main switch!
⇒Do not stop burn-off.
⇒The main switch may only be activated in “Shut down” or “Off”
mode.
Hot surfaces WARNING
Risk of burns from hot parts and poisonous smoke inhalation from
smouldering wood!
Before carrying out work in the boiler:
Wait until the “SHUT DOWN” or “OFF” status has been reached and
the boiler has cooled down.
Then switch off the main switch.
Electrical Hazards RISK
Electric shock may cause injury or death!
Only licensed technicians may perform work on electrical
components!
Observe all applicable standards and regulations!
Keep liquids away from the controller
Unauthorized personnel are forbidden from working on electrical components!
Liquids Note
Damage possible!
Keep liquids away from the insulation and control:
Only use a damp cloth to clean the system

Heating up boiler status during the heating process up to a certain minimum smoke gas
temperature.
Heating The boiler regulates combustion according to the target boiler values.
Maintain constant burn the boiler goes into “maintain glow” mode with very low power consumption.
ID fan at standstill, air dampers closed to minimum opening. If the output requirement
increases again, the boiler automatically switches to “Heating” mode.
Door open The insulating door is open, the fan runs at maximum speed.
Shut down The boiler has burnt out to minimum glow!
Error ATTENTION error! Troubleshooting: see chapter 7 Troubleshooting!
