<p>The present invention relates to a method of controlling a burner provided with combustion chamber, combustive air supply means driven by a motor, at least one combustible fluid supply duct interceptable by a respective electric valve means, and at least one exhaust duct for the combustion gases, characterized in that it comprises the following steps: - predetermining a minimum value and a maximum value for the current absorbed by the motor of said supply means; - establishing, for a plurality of flow rate values of combustible fluid supplied to the burner, the minimum supply voltage of the motor of the supply means for ensuring a combustive air flow rate suitable for ensuring correct combustion; - supplying combustible fluid to said burner at a predetermined flow rate; - detecting the supply voltage of said supply means and the current absorbed by the motor of said supply means; - checking that, for the supplied combustible fluid flow rate, the supply voltage is greater than a predetermined threshold value and that the value of the current absorbed does not diverge from a predetermined threshold value, and - generating an output control signal when at least one of the values of voltage and current does not comply with the respective thresholds.</p> |
