Combustion head adjustment

The air damper servomotor 4)(Fig. 4 on page 11) varies the air
output according to the output demand, while manually a lever-
age varies the combustion head adjustment.
The selection of the hole to be used is determined based on the
maximum output requested, as illustrated in Tab. I.
In the factory, the adjustment is adjusted for the minimum stroke
(hole 0, Fig. 14).
