Adjustment
The burner’s factory settings allow it to start in
most boilers. These are not operating settings.
They must be adapted in each case. Optimum
adjustment is possible only using flue gas
analysis instruments.
The correct adjustment is important for
good firing economy, high efficiency and low
environmental impact.
On account of irregular supply from the feed auger in the
first few days, the burner should be adjusted after roughly
one week of operation.
For access to the burner’s adjustment knob/switch,
the burner cover must be detached.
1. Check the settings
23, 25, 26 and 27 must be as shown in the figure.
