ABSTRACT:
The present invention discloses an open gas fire having a gas burner, the combustion products of which are fed to a flue system via a heat exchanger for use in providing heated convection air. In the invention an adjustable baffle is arranged to vary the flow-through cross-section of the path of the combustion products to the flue system, thus matching the flue cross-section to the combustion products quantity, thereby reducing the quantity of cold air drawn into the front of the fire and improving thermal efficiency of the gas fire apparatus.
