Water heater maintenance includes periodic tank flushing and cleaning, and removal of lime scale. The unit should be
inspected and adjusted to maintain proper combustion. Refer to Table 5, Suggested Maintenance Schedule (next page).
A periodic inspection of the venting system should be made.
Burner Flame Check
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 31). The burner flames should be a blue flame near the burner surface in a uniform flame
pattern. Occasional yellow or white streaks are normal.
