Modular fireplace with interchangeable burner assembly and heat exchange insert

摘要

A gas fireplace assembly for connection to a venting system comprises an outer shell for installation in the interior space of a building with the venting system extending into the outer shell. A fireplace unit is insertable within the shell that includes a combustion chamber. The combustion chamber includes a removable platform supporting a burner unit to be secured within the combustion chamber. The existing venting system is connected to the combustion chamber. The foregoing arrangement permits easy conversion of the fireplace assembly to different styles of decorative burner units or from a decorative gas burner to an efficient heating fireplace system and vice versa in a simple and economical manner.
