Start-up
How long it takes the fire to start depends on the type
of wood used; rough spruce may need only 2 minutes,
smooth beech may require 5 minutes until the required
exhaust temperature of 100 °C is reached.

Closing the ignition door and insulation door at
100 °C exhaust temperature
Once a few logs are burning well and the exhaust
temperature is over 100 °C, close the ignition door and
the insulation door.
Fig. 6-16: Closing the doors
The exhaust temperature is displayed in the boiler
overview. At over 100°C, an arrow appears to indicate
that the ignition door should be closed.
When the insulating door is closed, the boiler automat-
ically switches to [Ignition] mode and, once the
residual oxygen content is below 15%, to [Heating]
mode. The boiler is now in heating mode and regulates
the combustion of the wood independently.
Avoiding opening boiler doors unnecessarily
Avoid opening the insulating door and the fuel
chamber door unnecessarily in [Heating] mode. That
disrupts the boiler control and increases fuel consump-
tion. Also keep the ignition door and the combustion
chamber door closed.
CAUTION!
Leaving the doors closed in heating mode
Never open the insulating door and the fuel
chamber door when the boiler is in [Calibrating
lambda probe] or [Overtemperature] mode.
Completion of heating mode with ember burnout
Once the wood in the boiler has been burned (residual
oxygen content above 15% for more than 5 minutes) or
the exhaust temperature falls below 80 °C, the boiler
automatically starts the ember burnout ([Ember
burnout] status).
If the [Ember burnout] button was not
pressed, the boiler will flush the secondary air
ducts with air in order to free them of dust. Charcoal
and embers remain in the boiler by design so that
newly added wood can be ignited more easily.
Complete ember burnout for cleaning
To clean after the final heating mode, press the [Ember
burnout] button in the log boiler overview (the button
will then turn yellow ).
