HAZARD OF ELECTRIC SHOCK.
DISCONNECT ALL ELECTRICAL
POWER BEFORE WORKING ON BOILER.
S
ussman Electric Steam Boilers are designed for years of
trouble-free performance. To establish a good preventative
maintenance program, we suggest that the facility mainte-
nance 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 con-
ditioning 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.)
!
CAUTION
5.
A monthly inspection should be made of the internal
wiring. Open the access door and check all electrical
connections 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
indications 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
column can be examined visually and manually to see
if is clear and clean. If there are signs of scale or min-
eral deposit buildup the float control must be disas-
sembled and cleaned.
One of the lower heating elements should be
removed. If scale or mineral deposits have begun to
form all elements 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 nec-
essary.
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.
