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.
Display maintenance steps on the screen
With this boiler, the maintenance steps can also be
displayed on the ETAtouch control system screen. The
required activities will be explained to you step-by-step
and supplemented with detailed graphics. Each
maintenance is saved and the details can be viewed at
any time. So you can maintain a long-term overview of
the maintenance carried out. Of course, the
maintenance can also be carried out using the service
guide, without the support of the ETAtouch control
system.
To access maintenance, switch to settings in the boiler
function block ( [Settings] button) and then select
the function [Maintenance].
Fig. 2-1: Overview (example)
You can also access this overview by pressing
the maintenance switch. Also when the message
appears that maintenance of the boiler is required.
In the overview the different maintenance intervals are
listed in the upper area. This includes the maintenance
already carried out. With the button, information
about the selected maintenance is displayed.
Maintenance that you can carry out as an end
customer is labelled with the symbol. All others are
reserved for specialists and require authorisation.
Press the button to start the maintenance. The
individual steps are displayed on the screen. You can
switch to the next or the previous screen respectively
with the arrow keys on the left and right side of the
screen.

Follow the on-screen instructions and carry out all
steps carefully. Enter your name at the end of
maintenance ( button) and save the maintenance
with the button.
Fig. 2-3: End of maintenance
To end maintenance prematurely, press the right
arrow key several times until you get to the end.
There you can end the maintenance with the
button. Cancellation during a maintenance step is not
possible.
Explanation of the maintenance switch
The maintenance switch on the boiler is needed for
performing maintenance with the aid of the [Main-
tenance] function in the ETAtouch control system. This
displays the individual maintenance steps on the boiler
screen.
With this variant the heating mode is stopped, but
the boiler remains on at the mains switch. So that
all drives are disconnected, the safety chain of the
boiler is disrupted with the maintenance switch. The
screen will display a message when it is time to actuate
the maintenance switch.
Fig. 2-4: Maintenance switch
The maintenance switch is marked with the
symbol and has two settings.
•"1" = regular operation
This is the standard position of the maintenance
switch. The boiler can execute heating mode in this
position.
•"0" = maintenance mode
In this position, all drives are disconnected to
perform maintenance. The circuit boards,
however, are still live.
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.
Replace the wear parts (e.g., seals) with new
items.
Lubricate the components. The lubricant to
use is listed in the respective step.
Mount the components (e.g., screws or nuts)
by hand only, without tools.
Tighten the components (e.g., screws or
nuts) with a tool.
Install the components with some force (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.

Maintenance notes Cleaning and maintenance
Clean panels
If necessary, clean the panels of the boiler and the
ETAtouch screen with a moist cloth.
Under no circumstances use aggressive
solvents, chemicals or scouring agents. They can
lead to stress cracks and damage.
Wear a protective mask to avoid injuries to
the airways.
Seal the components. The sealant to use is
listed in the respective step.
Use adhesive to affix the seals, for example.
Only blow out the components with your
mouth.
Affix a seal. The required cross-section and
sealing material are given at each step.
Tighten the screws or nuts alternately and
evenly.
Do not use compressed air to clean the
components.
Do not use cleaning brushes to clean the
components.
Do not use an ash vacuum or vacuum
cleaner.
Do not lubricate the components.
No water or moisture in this area.
No leaks in the components, e.g. screw
