Cleaning the combustion chamber and heating surfaces
Thoroughly clean the combustion chamber and heat-
ing surfaces with a water jet.
!
Please note
Scratches on parts that come into contact with
flue gas can lead to corrosion.
Only use plastic brushes, no wire brushes or
sharp objects.
For normal cleaning, flush the heating surfaces thor-
oughly with a jet of water. For stubborn residues, sur-
face discolouration or soot deposits cleaning agents
may be used.
For this, observe the following:
■
Only use solvent-free cleaning agents. Ensure that
no cleaning agent gets between the boiler body and
the thermal insulation.
■
Remove soot deposits with an alkaline cleaning
agent with surfactant additive (e.g. Fauch 600).
■
Remove coatings and surface discolouration (yellow-
brown) with slightly acidic, chloride-free cleaning
agents based on phosphoric acid (e.g. Antox 75 E).
■
Remove loose deposits from the boiler; thoroughly
flush the heating surfaces and the flue gas collector
with a water jet.

Checking the gaskets and thermal insulation sections
1.
Check the gaskets and packing cord in the boiler
door for damage.
2.
Check the thermal insulation components on the
boiler door for damage.
3.
Replace any damaged parts.
Checking all connections on the heating water side for tightness
Danger
There is a risk of injury when working on pres-
surised components.
The connections on the heating water side must
only be opened after the boiler has been dep-
ressurised.
Only drain the boiler with a suction pump when
the boiler air vent valve is open.
Note
Also check the connections for the control equipment
and the minimum pressure switch (low water indicator)
for tightness.
Cleaning and reconnecting the condensate drain system
Note
Clean the inside of the condensate drain system at
least annually.
