At the time of installation and at monthly intervals, a visual check of the burner flames should be made to
determine if they are burning properly. The main burner may be seen through the sight glass window on the
front of the combustion insert mounting bracket (see Figure 32). The burner flames should be a blue flame
near the burner surface in a uniform flame pattern. Occasional yellow or white streaks are normal.
