Combustion head adjustment
At this point of the installation, the combustion head is fixed to the
boiler as shown in Fig. 12. It is therefore especially easy to adjust,
and this adjustment depends only on the maximum output of the
burner.
Two combustion head adjustments are available:
–
external air R1
–
central gas/air R2
In the diagram of (Fig. 15), find the notch at which both air and
central gas/air should be adjusted.
Provide an adequate lifting system of the burner.
ATTENTION
The burner-boiler seal must be hermetic; after
burner start-up check there is no leakage of flue
gases into the external environment.
