4.3 Set mixing head
4.3.1 Setting diagram
Set mixing head relative to the combustion heat rating required. Therefore the flame
tube setting and air damper setting are matched.
Do not operate the burner outside of the capacity graph.
Determine the required flame tube setting (dimension S1) and air damper setting
from diagram and note down.
