If you have converted your Ruby35 to be used with glass media (CKRUBY35), the LINER-MOD35-BK, is a modern Black Reflective Black Glass Liner. It is the only liner option for use in your converted Ruby35.
If your Ruby35 is not converted for glass media usage, there are 3 additional liner options available for use with the traditional log set included. Other liner options for traditional looking Ruby35 are the Tavern Brown Brick Liner (BRICKMI35CR), Traditional Cottage Red Brick Liner (BRICKMI35CR) and the more contemporary looking Reflective Black Glass Liner (LINER-BK-35). A liner is required with the Ruby35.
When using the Glass Conversion kit, making your fireplace a contemporary-look fireplace, the LINER-MOD35-BK, reflective black glass liner must be ordered.
