Release cam 4)(Fig. 38) from the servomotor, by pressing and
shifting button 3)(Fig. 38) to the right. Manually rotate it
backwards and forwards to make sure it moves smoothly. Now
engage the cam again by shifting the button 2)(Fig. 38) to the left.
Combustion head
Open the burner and make sure that all components of the
combustion head are in good condition, not deformed by the
high temperatures, free of impurities from the surroundings
and correctly positioned.
Fan
Check to make sure that no dust has accumulated inside the fan
or on its impellers, as this condition will cause a reduction in the
air flow rate and provoke polluting combustion.
