Cleaning and maintenance
Tar deposits can have several causes, for
example:
•
leak air through the heat exchanger cover, the
combustion chamber door or the lambda probe.
•
an incorrectly calibrated lambda probe
•
overly moist wood chips
•
insufficient boiler runtime (start-stop operation)
Check heat exchanger cleaner
Remove the cover for the heat exchanger cleaner
drive.

Manually operate the lever and check its ease of

with a heat-resistant lubricant.
