2 Cleaning and maintenance
2.1 Maintenance notes
Performing regular cleaning and maintenance
To ensure satisfactory functionality, cleaning and
maintenance must be performed at regular intervals.
You will receive a timely reminder about this from the
ETAtouch control system.
Cleaning of the boiler must be carried out at least
once a year, or when requested by the control
system. Maintenance is necessary at least every
3 years, or when requested by the control system. We
recommend that you perform maintenance annually.
You can also enter into a service agreement for your
heating system. Find out more from your heating
contractor or customer service.
All tasks where the maintenance table reads
"Customer" or "Customer or expert" in the column
"To be carried out by" can be carried out by any trained
adult. Instruction may be provided by the heating
technician or our customer service.
Steps that are marked with "Expert" only can only be
carried out by the heating technician or our customer
service.
Operation only by trained personnel
The product may be operated by trained adults only.
Training may be provided by the heating technician or
our customer service. Please read the associated doc-
umentation carefully in order to avoid errors during
operation and maintenance.
Persons who lack experience and knowledge as well
as children may not operate, clean, or maintain the
product.
Clean and maintain the precipitator together with
the boiler
The intervals for cleaning and maintaining the precipi-
tator correspond to those for the boiler. Therefore,
clean and upkeep the precipitator in the course of
cleaning and upkeeping the boiler.
Clean the precipitator before the emission
measurement
We recommend cleaning the precipitator before an
emission measurement is made. Therefore, empty the
precipitator ash box and clean the piping between
boiler and precipitator. Also clean the flue gas recircu-
lator if one is installed.
Explanation of pictograms
Switch the boiler on/off with the mains
switch.
Perform a visual check of the components.
Clean the components with a soft cloth, for
example.
Remove deposits with a vacuum cleaner or
an ash vacuum.
Remove deposits with the poker.
Remove deposits with the cleaning brush.
Replacethewearparts(e.g.,seals)withnew
items.
Lubricate the components. The lubricant to
use is listed in the respective step.
Mountthecomponents(e.g.,screwsor nuts)
by hand only, without tools.
Installthecomponentswithsomeforce(e.g.,
the retaining tube or the Lambda probe).
Handle the components carefully, since they
break very easily.
Measure or check dimensions or clearances
on the components.
Mark the components so that the correct
position can be found, for example, when
mounting.
Wear a protective mask to avoid injuries to
the airways.
Seal the components. The sealant to use is
listed in the respective step.
Use glue to adhere the seals, for example.
Do not use compressed air to clean the
components.

2.4 Regular maintenance
2.4.1 Empty the ash box
End heating mode
End the boiler's heating mode with the On/Off switch in
the boiler overview window. The boiler performs an
ember burnout and then changes to the [Switched off]
operating mode. Then start de-ashing, so that the
boiler can perform a final de-ashing.
Empty the ash box, inspect the seals
If the boiler ash box is already empty, also empty
the precipitator ash box. This prevents an
additional boiler switch-off.
Open both side fasteners by pressing their locks in the
direction of the arrow.
Fig. 2-1: Ash box
Remove the ash box from the precipitator. Remove the
cover by opening the fasteners and empty the ash box.
Fig. 2-2: Cover
Inspect the seal on the ash box cover to ensure it is in
good order, and replace it if necessary.
Fig. 2-3: Seal
Inspect the ash box seals on the precipitator to ensure
they are in good order and replace if necessary.
Fig. 2-4: Seal
After emptying the ash box, replace the cover on the
ash box and attach the ash box to the precipitator with
the two fasteners.
Fig. 2-5: Ash box
Once the ash box is attached, precipitator de-
ashing starts automatically in order to transport
the remaining ash to the ash box.

Regular maintenance Cleaning and maintenance
Switch the boiler on via the mains switch and start
de-ashing
Restore the boiler's power supply from the mains

de-ashing. Switch the boiler back on with the On/Off
switch.
