Cleaning The Combustion Chamber And Heating Surfaces; Checking Gaskets And Thermal Insulation Parts - Viessmann Vitocrossal 200 Service Instructions For Contractors

Further details regarding the individual steps

Cleaning the combustion chamber and heating surfaces

Thoroughly clean the combustion cham-
ber and heating surfaces with a water
jet.
!
Please note
Scratches on parts that are in
contact with flue gas can lead to
corrosion.
Only use plastic brushes, not wire
brushes or sharp objects.
For normal cleaning, flush the heating
surfaces thoroughly with a water jet. You
may use cleaning agents if you notice
stubborn residues, surface discoloura-
tion or soot deposits.
For this, observe the following:
■ Only use solvent-free cleaning agents.
Ensure that no cleaning agent gets
between the boiler shell and the ther-
mal insulation.
■ Remove soot deposits with alkaline
cleaning agents with surfactant addi-
tives (e.g. Fauch 600).

Checking gaskets and thermal insulation parts

1. Check gaskets and packing cords in
the boiler door for damage.
2. Check thermal insulation compo-
nents on the boiler door for damage.
Commissioning, inspection, maintenance
■ Remove coatings and surface disco-
louration (yellow-brown) with slightly
acidic, chloride-free cleaning agents
based on phosphoric acid (e.g. Antox
75 E).
■ Remove loose deposits from the
boiler; flush the heating surfaces and
the flue gas collector thoroughly with a
water jet.
