Fireplace Glass, Fire Glass, & Fireplace Rocks

Unfortunately, you may not substitute or add any additional media (logs, glass) etc. to a ventless system. You could likely place glass or stones around the burner base without issue, but nothing may be placed atop the burner aside from what originally arrived with your ventless system and may only be placed exactly as described in the literature included with the fireplace. If you were to use the improper media or even incorrectly place the correct media, there's a chance of the burner flame being restricted and carbon monoxide exhausting into the living space.

Per the manufacturer, 10 pounds would cover 4 square feet of area.

No media that is used in gas units are not usable in electric and vise-versa.

Unfortunately, we are currently unaware of any products specifically designed to polish these stones.

The units we sell are tested and listed by various certification agencies, including UL, OMNI, and PFS. All of these agencies are generally recognized by local code offices.

It is likely that the glass pebbles cannot be returned to their original color, as the soda likely cooled them rapidly, causing contraction and the residue to be drawn into the glass. You may try soaking the pebbles in a tub of glass cleaner, as this might help to draw out the residue. If the color does return, rinse the pebbles in clean cool water before returning them to the fireplace.
