AUTO = automatic operation
ADJUSTING THE MAXIMUM CAPACITY OF THE BURNER
Position the selector, situated on the control panel, on position maximum power and proceed as follows:
Adjusting the maximum gas flow rate: - proceed as stated in the regulating the solenoid valves until you achieve the
correct gas flow, as established by analyzing the combustion process. Eventually adjust the gas flow rate using a suitable
allen wrench, alter the position of the cam(3) guide blade; if you screw it down, the flow rate is reduced; if you
unscrew it, the flow rate increases.
Adjusting the maximum air flow rate: Eventually adjust this position acting on the screw “1 “, after loosening nut “ 2
“.
Tighten the nut
“2”
in place once again
.
ADJUSTING THE MINIMUM CAPACITY OF THE BURNER
Position the selector, situated on the control panel, on position minimum power and proceed as follows:
Adjusting the minimum gas flow rate: using a suitable Allen wrench, alter the position of the cam(3) guide blade; if
you screw it down, the flow rate is reduced; if you unscrew it, the flow rate increases.
Adjusting the minimum air flow rate: adjust on limit switch for air damper “Low Flame” position adjustment.
ADJUSTING THE INTERMEDIATE BURNER CAPACITIES
Using the selector, start the servomotor (closing or opening) and position on 0 to stop the stroke; the adjustment is
made as outlined below. Repeat the operation for the other cam points.
Adjusting the intermediate gas flow rates: using a suitable Allen wrench, alter the position of the cam(3) guide blade;
if you screw it down, the flow rate is reduced; if you unscrew it, the flow rate increases.
