GLASS / GEMS QUANTITY DETERMINATION
CAUTION: Sand is used with natural gas systems only. Always use vermiculite for propane gas
systems.
The sand/vermiculite that come with the burner system are pre-measured and must be used per these
instructions (see GLASS / GEMS PLACEMENT section).
Decorative glass / gems (purchased separately) must be placed to cover the burner (but not on the valve or
pilot, if equipped). See Table 13-1 for the minimum bag requirement depending on your burner size. Additional
glass / gems may be purchased and placed around the burner if desired.
Should you wish to fi ll the entire fi replace fl oor with glass / gems; instead use Table 13-2 to determine how many
bags of glass / gems to order based on fi replace size.
One 10-lb. bag of glass / gems fi lls approximately 144 cubic inches.

These bag quantities listed allow for an approximate 2" depth of glass / gems in the entire fi replace fl oor,
without a burner. (The volume of the burner will take up some space, allowing for some excess glass to be
used as desired, or stored as extra for later use.)
Your fi replace area can be determined by measuring the
center width of your fi replace in inches and multiplying by
the depth from front to back in inches. You can then use
the area column in the table above to approximate the
number of bags needed.

CAUTION: When covering the burner with glass / gems; do not exceed 1" above the top of the burner.
Additional glass / gems directly on top of the burner may result in unsafe ignition.
