Tube Cleaning Procedure
(Typical)
Establish a regular inspection schedule, the frequency
depending on the local water condition and severity of
service. Do not let the tubes clog up solidly. Clean out
deposits over 1/16" in thickness.
Although the illustration shows the mechanical clean-
ing procedure of a small heater, it is typical of all sizes.
The heater may be cleaned from the return header
side as shown, without breaking pipe connections. It is
preferable, however, to remove both headers for bet-
ter visibility through the tubes and to be sure the
ground up lime dust does not get into the system.
Note that you do not remove the top pan or the heat
exchanger, generally.
After reaming, mount the wire brush in lieu of the
auger and clean out the debris remaining in the tubes.
Another method is to remove the heat exchanger,
ream tubes and immerse heat exchanger in non-inhib-
ited de-scale solvent.
