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.

“It’s hard to define the Topaz, says Doug Singer, president of RSF. The Topaz is definitely a high efficiency wood stove, but it can be a beautiful open fireplace when you want it to be. It’s ideal for spring and fall, when you don’t always want a lot of heat, but it can put a serious dent in your winter heating bills too.”

This fireplace is certified for use with 7" ICC Model EXCEL chimney only. The chimney system height from the top of the fireplace must be a minimum of 12 ft.
