BURNER FLAME
The flames from the burner should be visually checked
as soon as the heater is installed and periodically during
normal operation. In normal operation, at full rate, and
after operating for about 15 to 30 minutes, the flame
should be yellow and slightly taller than the rear log.
See Figure 49.
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
confi guration, and wind effects may cause the
fl ame patterns to vary.
