PLACING THE DECORATIVE ROCK
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 fl oor of the fi replace.
During initial operation of the new heater, burning logs will give off a paper burning
smell and orange fl ames will be present. Simply open the windows for a few hours to
vent the odor.
CAUTION
FLAME APPEARANCE
Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed.
In addition, periodically check the flames visually during operation.
CHECKING THE PILOT FLAME
The pilot fl ame must always be present when the heater is in operation.
It should just touch the top of the ther-
mocouple tip for natural. See Figures 27 and 29 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. See Figures 28 and 30
for incorrect shape of pilot flame.
