Caution! In case it is necessary to immediately shut the burner down while working at high flame and the maximum load point is
not already set observing the combustion parameters, decrease gas by means of the pressure governor as to drive the burner to
a sufficient excess of air, then shut the burner down by the main switch.
At next start-up, start again with point P2 to the minimum load (factory-setting - see previous paragraph) and go on setting the
curve points.
ATTENTION: When the maximum load is reached (100%), check again the curve-points. The pressure at the governor has
changed and therefore also the gas flow rate to the other points. So, it is necessary to check the adjustment of the points
already set.
ATTENTION: for proper operation, it is necessary that the curve of each actuator does not reverse its slope.
ATTENTION: When % load value is changed by user, LMV recalculates all the curve-points according the new load value. It may
happen that the point you are adjusting, once saved, is moved to another position.
