control apparatus operation of a combustion device

THE INVENTION CONCERNS A DEVICE OPERATION CONTROL DEVICE COMBUSTION TYPE INCLUDING A CONTROLLER MOBILE PASSING OF STARTING POSITION RELATED TO STOP AN INTERMEDIATE POSITION OPENING POSITION THEN ELL FINAL IGNITION, ORGAN ELECTRIC ENERGIZED TO OPERATE AND MAINTAIN POWER DURING OPERATION EVEN AFTER THE CONTROLLER IS INCOME POSITION THROUGH OPENING AND CIRCUIT DELAY COMMANDER BODY ELECTRIC. ACCORDING TO THE INVENTION, WHEN THE CONTROLLER IS IN 4 POSITION IGNITION B BODY ELECTRIC 10-15 MAY BE ENERGIZED FOR OPERATION DIRECTLY BY SOURCE OF ELECTRICITY 20 AND, AT THE SAME MOMENT, THE CIRCUIT DELAY 22 IS KEPT OUT OF ACTION, BUT WHEN THE CONTROLLER 4 LEAVES HIS POSITION IGNITION B DELAY CIRCUIT CAN START WORK 22. L INVENTION pREVENTS THE FAILURE IGNITION WHEN GAS LINE IS NOT SERVED TO CONTAIN AIR.
