Installation
5.8 Combustion head pre-calibration
Proceed as follows:

remove the 8 screws 2)(Fig. 16);

remove the 4 round blocks 1) fastened behind the stability
disc.
5.9 Combustion head adjustment
At this point of the installation, the combustion head is fixed to the
boiler as shown in Fig. 13. 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. 17, find the notch at which both air and
central gas/air should be adjusted.
ATTENTION
Combustion head must be pre-calibrated
exclusively for the model concerned, if its
maximum output is included in area B of the firing
rate (Fig. 2 on page 10).
