Abstract (en)

[origin: EP0100758A2] A safety device for gas heating apparatus, is provided which is responsive to a reduction in the oxygen content in the environment in which the apparatus is located, to close a main solenoid valve (3) controlling the gas supply. The device includes a temperature transducer the temperature sensitive element (13) of which is fixed to the outside of the wall (16) of a pilot burner tube (2) to detect its temperature. In dependence on the detected temperature, the transducer generates a signal which, when the pilot flame burns in a first position (A) in the pilot burner tube (2), corresponding to normal environmental conditions, maintains the gas-supply solenoid valve (5) open and which on the other hand causes the latter to close when the pilot flame burns in a second position (B) as a result of its displacement due to a lowering of the oxygen content in the environment.
