The Cottage Red Brick Liner is a traditional looking option for your Ruby35 fireplace insert. It offers a natural looking red-brick with dark mortar to the interior of your direct vent gas insert.
The Ruby35 does not include a liner and the Cottage Red Brick liner is one of 3 options available for the Ruby35 gas insert when using the traditional (included) ceramic log set. Other available liner options include the Traditional Tavern Brown Brick Liner (BRICKMI35TB) and the more contemporary Reflective Black Glass Liner (LINER-BK-35).
When using the Glass Conversion kit (CKRUBY35), making your fireplace a contemporary-look fireplace, the LINER-MOD35-BK, reflective black glass liner must be ordered.
