摘要： A forced suction and exhaust type gas burner apparatus comprising a gas burner unit and a fan motor for forcibly sucking air into said burner unit from the outdoor and exhausting the combustion gases from said burner unit to the outdoor so as to prevent air pollution in the room in which the burner unit is disposed and thereby to provide a sanitary environment inside the room. The gas burner apparatus is so designed that a stable combustion can be obtained and the suction and exhaust can be achieved in a rational manner, irrespective of variations in the flow resistances of suction and exhaust passages, the type of a gas used and line voltage and of differences in local frequency.
