A safety apparatus for interrupting the supply of a gaseous fuel to an air-fuel combustion burner when the air which is supplied to the burner is oxygen-deficient comprising: a main burner including an air-fuel mixing chamber and a combustion surface having a plurality of orifices in fluid communication with said chamber through which an air-fuel mixture can flow out of said chamber; a second burner including an air-fuel mixing chamber and at least one orifice in fluid communication with said chamber through which an air-fuel mixture can flow out of said mixing chamber; a means placing said main burner and second burner air-fuel mixing chambers in fluid communication to allow distribution of air from one of said chambers to the other of said chambers; a means for supplying a gaseous fuel to said mixing chambers of said main burner and said second burner, said gaseous fuel supply means being in fluid communication with both of said chambers; a means for igniting and combusting said air-fuel mixture flowing out through said orifices of said main burner and said second burner; and a means for sensing the combustion of said air-fuel mixture at said orifice of said second burner for detecting said oxygen deficiency of said air and for closing said gaseous fuel supply means in response to a detection of an oxygen deficiency in said air-fuel mixture.
