4E-1. Periodic Inspection of Heat
Exchanger Water Passages
Scale can build up inside the heat exchanger
tubes. The easiest way to determine the degree of
scale buildup is to periodically inspect the tubes.
Perform this inspection after 60 days of operation, and
after 120 days of operation. This will establish a
regular inspection routine.
An inspection and cleaning of the complete heat
exchanger can only be done by removing it from the
heater (see Section 2C for removal instructions).
