The GLASS-OY is a bag of Onyx Glass for your converted Contemporary Ruby35 fireplace insert. A bag of Onyx Glass is included with your CKRUBY35 (in addition to a bag of Diamond Glass). If you would like a solid onys glass bed, then an additional bag of Onyx is required. The Ruby35 uses approximately 1-1/2 bags of glass for the fire bed.
In addition to the onyx (GLASS-OY) and diamond (GLASS-DM) glass included with the CKRUBY35 glass conversion kit, sapphire glass (GLASS-SP), bronze glass (GLASS-BZ) are also available to help customize the look of your fireplace. Other additional media includes stones (STONES-NATURAL) and a driftwood log set (DWLG-MI-MAJ). Once you have converted your direct vent Ruby35 to a contemporary fireplace, a glass media bed is required for any additional media such as a stone kit or the the driftwood logs. Two bags of stones are recommended for the bed of your Ruby35. Adding glass media to your fireplace takes the traditional feel out of your recently converted old fireplace and gives it a modern, contemporary look.
Approximately 1-1/2 bags of crushed glass are recommended. When using the Glass Conversion kit (CKRUBY35), the LINER-MOD35-BK, reflective black glass liner is required. A refractory liner is not compatible with the CKRUBY35 kit.
