Burner FLaMe
The flames from the burner should be visually
checked as soon as the heater is installed and peri-
odically during normal operation. In normal opera-
tion, at full rate, and after operating for about 15 to
30 minutes, the flame should be yellow and slightly
taller than the rear log. Figure 64
If the flame is blue and only in the center, turn off
unit and let cool. After unit is cool, remove logs and
check to make sure the back holes in the burner are
not covered with rock wool. If the back holes are
clear, add more rock wool to the center of the burner.
Replace logs.
nOte: The type of installation, vent system
configuration, and wind effects may cause the flame
patterns to vary.
