Abstract: A flue shield is described for use within HVAC systems and inside of a combustion chamber. The flue shield can be installed around the burner and within the combustion chamber to help dissipate heat that builds up as a result of the combustion of gas and air. Extensions from the flue shield extend through holes in the combustion chamber and into tubes of a heat exchanger. An air gap is created between the flue shield and the inner surfaces of the combustion chamber and heat exchanger tubes. Installation of a flue shield provides better efficiency than insulation solutions, reduces stresses on the heat exchanger, and provides safety benefits.
