TABLE OF CONTENTS
NOTE:
This installation instruction covers two different ignition systems: Thermocouple Manual Safety (TMSI)
and Thermocouple Flame Sense (TFS). Look for your specific section in the table of contents.
All media (i.e. lava rock, lava stones, lava boulders and fire glass) has the potential of thermal
spalling. This is a process that may occur when media is wet and moisture gets trapped inside of
the material due to rapid temperature differences. When this happens the media has the potential
to crack or “pop” outside the fireplace.
WE HIGHLY RECOMMEND COVERING ALL FIRE FEATURES WHEN NOT IN USE
The use of a cover can lessen the impact of thermal spalling; however, heavy rains, high
humidity and the presence of moisture may still cause the media to pop.
ALWAYS USE CAUTION WHEN USING THE FIRE FEATURE
Extra caution should be taken when lighting a fireplace when heavy rains, high humidity and
moisture are present. Light the fireplace; leave the area allowing any moisture in the media to
dissipate. We strongly recommend that during this drying out time that you monitor the fire feature
from a distance. This drying out period should be no less than 30 minutes. Continue monitoring
the flame from distance to ensure that all popping has ceased before fully enjoying the fire.
