EMBER, GRATE, AND ROCK INSTALLATION

PLACING FLICKERING EMBERS

Place flickering bright embers (FBE-.1G) after placing logs on burner. Pull apart into small strands and place on top of existing rock wool in front of and between front logs where they can be seen. Try to avoid stacking these embers on top of each other. Use smaller, stringier strands for maximum effect. Use as much as needed until desired effect is achieved.

PLACING THE DECORATIVE ROCK

CAUTION

DO NOT sprinkle volcanic rock on the logs, around the pilot, or on or near burners. This may cause sooting. Place volcanic rock only on the ﬂoor of the ﬁreplace.

During initial operation of the new heater, new burning logs and/or rock wool will give off a paper burning smell and orange ﬂames will be present. Simply open the windows for a few hours to vent the odor.
