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.
