Cleaning The Heating Surfaces; Checking The Condensate Drain And Cleaning The Trap - Viessmann Vitodens 200-W B2HE Installation And Service Instructions Manual

Cleaning the heating surfaces

!
Please note
Scratches to the surfaces of the heat exchanger
that come into contact with hot gas can result in
corrosion damage. Brushing can cause deposits
to become lodged in the gaps between the coils.
Never use brushes to clean the heating sur-
faces.
!
Please note
Prevent damage due to cleaning water.
Cover electronic components with suitable
watertight material.
Note
Discolouration on the heat exchanger surface is a nor-
mal sign of use. It has no bearing on the function and
service life of the heat exchanger.
The use of chemical cleaning agents is not required.
