1. A gas burner device, comprising:
- a gas supply means;
a gas burner receiving gas from said gas supply means;
a primary air supply duct means for supplying primary air to said burner;
a secondary air supply duct means for supplying secondary air to said burner, said primary air supply and secondary air supply maintaining combustion of said gas to produce a flame;
a flue gas vent means leading from said burner and flame for venting flue gases to a place of disposal;
a power driven fan means communicating with said flue gas vent means for providing simultaneously a forced flow of flue gases away from said flame and of said primary and secondary air to said flame;
a temperature responsive variable speed control for controlling the power supplied to said motor and thereby the speed of said fan; and
a flue gas temperature sensor means in said flue gas vent operatively connected to said motor speed control for controlling the speed of the fan and thereby simultaneously the rate of flow of the flue gases and the primary and secondary air by said fan in direct relation to the temperature of said flue gases.

Abstract
A gas burner device having a gas supply and a primary air supply and secondary air supply to the burner and a flue gas vent means leading from the burner for venting flue gases to a place of disposal. The device has a power driven fan in the flue gas vent for providing simultaneously a forced flow of flue gases away from the burner flame and of primary and secondary air to the flame, a temperature responsive variable speed control for controlling the power supply to the fan motor and thereby the speed of the fan and the rate of movement of the exhaust gas from the burner and flame and primary and secondary air to the flame in direct proportion to the temperature of the flue gases.
