Abstract

The invention discloses a control and monitoring equipment for gas burners which, when the figure of the reference temperature of the medium to be monitored has been reached, if the flame continues to burn in the burner after the safety gas solenoid valve has been de-energized, the feeding of the motor (M) of the electric fan supplying air for the combustion continues, said feeding being insured by the closing of the contacts (B1, B2) placed before the motor (M) of the electric fan, before a first relay (B) belonging to the power circuit and which is excited by the closing of a normally closed contact (1E), wherein said normally closed contact belongs to a second de-energized relay (E) inserted in the logic part of the equipment, said second relay (E) being placed in series to a first resistance (BLG) wound around a bi-metallic element and in parallel with a closed contact (2RF) belonging to the flame monitoring logic circuit (A RF), the feeding of the motor (M) ceasing when the flame goes out because of the commutation of the contact (2RF) belonging to the flame monitoring logic circuit (A RF). <IMAGE>
