In a cross flow type burner apparatus, a burner is provided to which a gaseous fuel and air are supplied by a blower. An air reduction member is provided to reduce an amount of air supplied to specified flame holes of the burner wherein the reduced amount of air is less than the amount of air supplied to the other flame holes. A temperature sensor is provided to detect the burning condition of flames built up on the specified flame holes. A safety member is activated depending on an output generated from the temperature sensor.
