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 62.
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.
