HAZARD OF ELECTRIC SHOCK.
DISCONNECT ALL ELECTRICAL POWER BEFORE WORKING ON BOILER.
Sussman Electric Steam Boilers are designed for years of trouble-free performance. To establish a good preventative
maintenance program, we suggest that the facility maintenance person or engineer familiarize themselves with
these simple rules.
1.
The use of chemical boiler cleaning compounds voids all warranties and should not be used. Some compounds
can/will damage the incoloy sheathing of the heating elements. A reputable water treatment-engineering firm
should be consulted regarding pre-treating or conditioning the boiler feed water.
2.
Daily blowdown at pressure is essential for ideal boiler performance. Extended periods of operation may require
more frequent blowdown. If the boiler is not equipped with an automatic blowdown, in order to safeguard the
heating elements, it is recommended to turn both the main disconnect switch and the boiler switch to the off
position before manually blowing down the boiler.
3.
The sight glass should be checked frequently to assure the boiler has adequate water.
4.
The sight glass should be checked daily for damage (i.e. scratches, erosion, leaks etc.) The sight glass should be
replaced if damaged. [See insert.]
5.
A monthly inspection should be made of the internal wiring. Open the access door and check all electrical con-
nections for tightness. Replace any wires that show signs of damage.
NOTE:
The electrical power MUST be shut off during this maintenance procedure.
6.
Heating element mounting bolts should be checked and tightened to a torque of 22 ft.-lbs. If there are indica-
tions of steam leaks from an element, replace the element gasket.
7.
A monthly check for leaks should be made; any loose or damaged fittings should be tightened or replaced.
8.
Every four months the boiler float control should be checked for proper operation. The lower equalization col-
umn can be examined visually and manually to see if is clear and clean. If there are signs of scale or mineral
deposit buildup the float control must be disassembled and cleaned.
One of the lower heating elements should be removed. If scale or mineral deposits have begun to form all ele-
ments should be removed cleaned and reinstalled using new element gaskets.
Operating and high limit pressure control operation should be checked. Pressure controls should be removed and
cleaned if necessary. Water feed supply check valves should be inspected and replaced if necessary.
9.
If the boiler is equipped with an electronic auxiliary low water cut-off every four months the probe should be
removed and checked for deposits. The probe should be cleaned and reinstalled.
