LOG PLACEMENT
FILLING THE BURNER PAN
Fill the burner pan with vermiculite to the bottom of the rear log and sloped to the front edge of the burner pan. Excess ver­miculite can spill forward or to the side of the burner pan. Do not overfill the propane model. Do not cover the pilot (if SPK or MVVK is installed) with vermiculite or rock wool (embers).
PLACEMENT OF GLOWING EMBERS (ROCK WOOL)
The Wildfire flame appearance can vary due to differences in draft and fireplace configurations and ember placement. After installing rear (#1) and front logs (#2 and #3), cover the entire top surface of the vermiculite in the burner pan with the rock wool supplied with unit. Tear the rock wool into pieces approximately 1/2" in size (roughly the size of a nickel) and cover the burner evenly. Do no use more rock wool than the amount supplied with the unit. To enhance the appearance of the Wildfire flame, it is recommended to form a mound of rock wool in the center of the burner, 2" to 3" high, visible through the two front logs.
PLACEMENT OF DECORATIVE VOLCANIC ROCK
Sprinkle volcanic rock in front of front glowing embers and to both sides.
DO NOT SPRINKLE ON BURNERS, EMBER BED, PILOT OR LOGS.
IMPORTANT: Do not handle logs with your bare hands! Always wear gloves to prevent skin irritation from ceramic fi bers. After handling logs, wash your hands gently with soap and water to remove any traces of fi bers.
