Abstract

A furnace assembly is disclosed that includes an intake manifold connectable to a fuel supply, a partition panel, and a burner assembly mountable to the partition panel and operable to combust a pre-mixed fuel and air mixture to produce a heated flue gas. The burner assembly includes burners configured to combust of the mixture into a flue gas. The burner assembly also includes a heat shielding plate located and shaped to reduce heat communicated to the partition panel due to the combustion. The heat shielding plate is manufactured using a high-temperature alloy and includes holes, each hole aligned with one of the burners. A groove in the plate accommodates thermal expansion of and reduces thermal deformation of the plate. A heat exchanger is mounted to the partition panel in thermal communication with the burners that includes tubes positioned to receive the heated flue gas.
