In normal operation at full rate after 15 minutes, the following flame appearances should be observed:
The rear flames above and behind log #2, and in front of log #3, may be yellow. The flames should extend approximately 2" -
4" above log #2. Refer to Figure 27.
Figure 27 - Correct Appearance of Rear Flames
The front flames are blue , becoming yellowish as they hit the bumps on the face of log #2. The face of log #2 will glow a
bright reddish orange when the heater is in operation.
NOTE: When the log set is turned on for the very first time, the burner flames in front of log #2 will appear
an opaque orange on the surface of log #2. After two or three hours of continuous operation on the
highest setting, the normal bright orange/red glow should be visible.
OPERATING INSTRUCTIONS
Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the fireplace. Do not place
a blower inside the burn area of the firebox. Ceiling fans may create drafts that alter flame patterns. Sooting and improper
burning will result.
During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or
bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as they are burned off during
the initial operation of the appliance, possibly causing headaches or eye or lung irritation. This is a normal and temporary
occurrence.
The initial break-in operation should last two to three hours with the burner at the highest setting. Provide maximum ventila-
tion by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in will be slight
and will disappear with continued use.
This appliance must not be used with glass doors in the closed position. This can lead to pilot outages and severe sooting
outside the fireplace.
