The Topaz is the first built-in fireplace to seamlessly combine a beautiful open fireplace with the performance of an EPA approved controlled combustion stove. The Topaz's unique hideaway ceramic glass door is an industry first which enables you to choose between a controllable high performance wood burning stove and the crackle of a real open fireplace. Whatever the choice, it takes just seconds to convert the Topaz from an open fireplace to an EPA certified high performance stove. The Topaz incorporates a unique façade which eliminates the need for any non-combustible facing whatsoever making it the easiest and most flexible unit on the market to finish.
