GLASS QUANTITY DETERMINATION
CAUTION: Sand is for use with natural-gas systems only. Always use R.H. Peterson
Lava-Fyre Granules™ for systems using propane gas.
The glass and either sand or lava that come with the burner system are pre-measured and must
be used per these instructions (see GLASS PLACEMENT section).
Additional decorative glass may be placed on or around the burner (but not on the valve or pilot).
Use Table 5-1 to determine how many bags of glass to order based on fi replace size.

*One bag of glass is included with a bag of either sand or Lava-Fyre Granules™ to cover the
burner. One 10-lb. bag of glass fi lls about 155 cubic inches. The burner is 2 inches tall.
Note: 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 of glass needed. See-
through or rectangular fi replaces will have greater area than a fi replace with the same
size front opening in which the side walls taper inward as shown in Fig 5-1.
CAUTION: Covering the burner with glass more than 1" above the top of the burner may
result in unsafe ignition. Use only the glass provided with the burner to cover
the burner itself. Do not use extra decorative glass directly on top of the burner.
