Combustion head adjustment

Installation operations are now at the stage where the blast tube
and sleeve are secured to the boiler as shown in Fig. 15.
It is now a very simple matter to set up the combustion head, as this
depends solely on the maximum output developed by the burner.
It is therefore essential to establish this value before proceeding to
set up the combustion head.
There are two adjustments to make on the head:
– outside air R1
– central air R2
