Abstract
The device comprises a safety valve with an actuator which can be armed manually, a regulation valve disposed in a duct downstream of the safety valve for supplying a main burner, a tapping duct for supplying a pilot burner, and a flame detector for the pilot burner for supplying the actuator of the safety valve with sufficient energy to hold the safety valve open after manual arming has taken place and the pilot light has been lit. In order also to supply another burner without compromising the safety of the device, an on/off valve provided in a duct branching off the main duct between the safety valve and the regulation valve has an operating member coupled to the manual arming member of the actuator of the safety valve for keeping the on/off valve in a condition in which it shuts off the branch duct during the manual arming of the safety-valve actuator.
