Regular maintenance Cleaning and maintenance
2.3 Regular maintenance
Check fill level of ash bins
The boiler does not have to be switched off to
empty the ash bins or container.
Before starting thede-ashing emptying, press the
[De-ash] button. This prevents the ash screw
from switching on during the emptying process. If the
ash screw already has a malfunction, first empty the
ash bins or the container and then acknowledge the
fault.
De-ashing with transfer flap
1. Lift the protective mat from the underside. Move
the container to the side and empty.
Fig. 2-2: Protective mat
2. Before placing the protective mat, make sure the
adhesive seal is in a good condition to prevent ash
from escaping.
Fig. 2-3: Seal on the sealing plate
De-ashing with ash bins
1. Turn the locks on the ash bin lid upwards by 90°.
Fig. 2-4: Open the locks
2. Push the lid up and fix in "Park position".
Fig. 2-5: Park position
3. Empty the ash bins. Unhook the lid from "Park
position" and fix to the ash bin with the locks.
DANGER!
Risk of injury from the ash screw
If only one ash bin or none at all is
connected, the ash screw is accessible
from below.
For this reason, operation with only one ash
bin or none at all is prohibited. In addition,
the boiler would take in leak air and hot ash
would fall to the ground, increasing the fire
risk.
The boiler may not be operated for more than
2 minutes without ash bins or an ash container.
