Probes
Level probes should be periodically checked. If there is any seepage between the
conductor and its insulator or between the insulator and the compression fitting,
replace the probe.

CLEANING THE BOILER
Boiler should be drained and cleaned periodically to remove any accumulated
scale or sludge. This can normally be done at the time of annual inspection unless
experience indicated that more frequent cleaning is required. Check for pitting of
vessel wall near water level and bottom head. Removal of the lowest element
flange usually facilitates this inspection.
