A gas burning furnace system is disclosed, including a blower which draws air from outside the home for combustion. The blower forces combustion air to the gas burner via a pressure box situated between the blower and the burner. The pressure box encloses a barrier having an adjustable aperture therein, through which the combustion air must pass before reaching the burner. By adjusting the size of the aperture, the rate of supply of combustion air to the burner can be regulated so as to produce complete fuel combustion without cooling the firebox.
