(57) 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).
