Inspection
Scale can accumulate inside the heat exchanger
tubes. The easiest method of determining the degree of
scale buildup is to periodically inspect the tube having
the highest temperature. This can be done by removing
the drain plug on the right side of the heater (see Fig.
35). Perform this inspection after sixty days of opera-
tion, and after 120 days of operation. This will estab-
lish a regular inspection routine.
