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.
