Installation
REFER TO NATIONAL AND ALL APPLICABLE LOCAL CODES FOR SPECIFIC INSTALLATION REQUIREMENTS.
1. The boiler should be mounted on a solid, level foundation.
2. The boiler should be located with suitable clearances, refer to page 3 and Code requirements.
NOTE: Allow minimum of 21 inches clearance in front of door for servicing of heating elements.
Piping
ALL PIPING SHOULD BE INSTALLED BY A QUALIFIED LICENSED PLUMBER IN ACCORDANCE WITH
NATIONAL AND LOCAL CODES.
1. When water feed is other than pump type the water
supply pressure must be 10 psig greater than boiler operating pressure to assure water supply maintains proper
water level in the boiler. Insufficient water levels can result
in improper boiler operation. (Keep feed water valves
open at all times during normal operation.)
2. If pump and boiler are plumbed within 30 feet (pipe
length) a minimum of 2 check valves are required to
avoid damage to pump.
8
3. Connect steam line with customer supplied outlet valve
to boiler steam outlet.
4. Provide for boiler drain connection, a daily blowdown is
required. A "Blowdown Separator Tank" may be necessary, check with local code.
5. Safety valve shall be plumbed according to local code.
NOTE: The safety valve shall not be plumbed with a line
sized less than the outlet size of the safety valve.

Wiring
ALL ELECTRICAL WIRING MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN IN
ACCORDANCE WITH NATIONAL AND LOCAL ELECTRICAL CODES.
!
Assure that the power voltage and phase being supplied to the boiler matches the power
voltage and phase of the boiler. Connecting incorrect power supply can damage boiler components or
cause improper boiler operation. If the boiler power requirements do not match the power to be supplied to the boiler the
boiler must be returned to the factory for conversion. Boilers cannot be field converted.
CAUT
ION
ALL BOILERS ARE PRE-WIRED AND TESTED PRIOR TO SHIPMENT.
1. Ground boiler according to National Electric Code requirements to avoid shock.
2. Power wiring to boiler should be in accordance with National and Local Electrical Code requirements following wiring
diagram supplied. Use proper size wire. Wire size is specified adjacent to field wiring terminals. This label states the wire
size [AWG or MCM], minimum temperature rating (90 C) and conductor material (copper only). Deviation from these
requirements may result in improper or unsafe boiler operation.
3. A disconnect switch employing circuit breakers or fuses should be installed between the main power source and the boiler. This disconnect switch should be located near the boiler and clearly marked for easy access and identification should
the boiler need to be turned off due to an emergency.
4. Boiler control circuit is 120 Volt*. Unless boiler has an optional step down transformer, a separate 120 Volt power feed
wiring is required to be connected to the control circuit terminal block. A 15 Amp circuit is required for all boilers. If a
3/4 HP feed water motor and pump assembly is connected to the boiler, then a 20 Amp circuit is required.
5. If a separate control circuit is used, it should be connected to the control circuit terminal block.
6. Remote mounted water feed systems (i.e. condensate return, motor and pump) should be connected to the junction box
provided on the outside of the boiler jacket.
7. With main power off, make sure all wiring terminations are tight to avoid arcing, carbonizing or overheating of contacts.
!
Boilers are susceptible to lightning damage due to water line connections. An industrial type
lightning/surge protector should be installed according to the manufacturer's recommendation at the
service entrance. Consult your contractor or electrical dealer.

Main disconnect switch is to be in the "on" position. Boiler main
switch is to be in the "on" position. Since boiler will be empty
the pump or solenoid will be energized allowing the boiler to
fill with water. Control will automatically fill boiler to proper

Blowdown
A daily blowdown is an essential part of boiler operation. It is the best and most important part of preventative maintenance you
can give your boiler and will add years of life to the unit. Make sure a blowdown schedule is established and followed regularly.
In extremely hard water areas, blowdown may be necessary more than once a day. If there is a particular problem that
applies to your local water condition (i.e. high concentrations of minerals etc.) we recommend a consultation with a reputable local water treatment-engineering firm. Pre-treating the boiler feed water may reduce mineral accumulation enough
to allow a daily blowdown to be sufficient.

Maintenance
!
HAZARD OF ELECTRIC SHOCK.
DISCONNECT ALL ELECTRICAL
POWER BEFORE WORKING ON BOILER.
CAUT
ION
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
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 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 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 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.

Optional Equipment
AUXILIARY LOW WATER CUT OFF
• For model ES & HU boilers P/N ES81017 & ES81017MR (w/ manual reset).
• For model SSB boilers p/n SSB81017 & SSB81017MR (w/ manual reset).
Senses water level electronically using a resistance probe. When a low water condition is detected, the contactor
control voltage circuit is interrupted and the heating elements are de-energized. When water level returns to
proper levels voltage is restored to the contactor coils and the elements are re-energized. For controls with a
manual reset button voltage to the contactor coils is not restored until the water level has returned to proper
operating levels and the reset button is pushed. Do not depress the reset button before the correct water level is
achieved.
LINE PRESSURE WATER FEED SYSTEM
• For model ES & HU boilers P/N ES99117
• For model SSB boilers P/N SSB99117
Water feed system used to supply makeup water to the boiler when incoming water line pressure is 10 psig
greater than the operating pressure of the boiler. Completely factory plumbed and wired; 0-100psig range; 1/2”
NPT size. Consists of strainer, solenoid valve (120/1/50-60Hz), and check valve for automatic feed. For SSB boilers
P/N SSB99117 components are of stainless steel construction.
HIGH PRESSURE WATER FEED SYSTEM
• For model ES12-72 P/N ES38002A
• For model ES100-180 P/N ES38020A
• For model SSB12-72 P/N SSB38002A
• For model SSB100-180 P/N SSB38020A
Used to supply makeup water and to maintain constant water level when the boiler operating pressure is equal
to or greater than incoming water line pressure and condensate is not returned to the boiler.
• ES38002A & SSB38002A – Range is 0 – 100 psig, 1/2” NPT size consisting of strainer, solenoid valve and 1/3 HP
120/1/60 motor and pump.
• ES38020A & SSB38020A – Range is 0 – 125 psig, 3/4” NPT size consisting of strainer solenoid valve and 1/2 HP
120/1/60 motor and pump.
These assemblies are mounted on rubber shocks and secured to a steel base mounting plate. These units require
field plumbing and wiring to the boiler. SSB38002A and SSB38020A pump components are of stainless steel construction.
CONDENSATE RETURN SYSTEM (see page 17)
• For model ES12-72 p/n ES38083V; for model ES85-180 p/n ES38084V.
These systems are used whenever condensed steam can be collected for reuse in the boiler. Returning the condensate to the boiler can save a significant amount of energy. The water returned is relatively free of corrosive
minerals and carries a substantial amount of heat that does not have to be replenished. A vacuum breaker is
required whenever a condensate return system is used.
Each system consists of a vertical condensate return tank, a motor and pump and support plumbing. A 1/2”
inlet is located on the tank to accept make-up water. A vent fitting is located on the condensate tank top for
atmospheric air venting. The return fitting is to be plumbed to the trapped condensate return line coming
from the process.
A gauge glass and valve set are mounted on the side of the condensate tank. The tank has a ball check valve
internally mounted, and a float arm and float ball assembly that serve mechanically allowing make-up water to
enter the tank as the original supply is used. The pump discharge outlet is to be plumbed to the boiler check
valve. The tank drain valve should be plumbed to a proper drain line. The motor is required to be wired to the
boiler.

Optional Equipment (cont)
VACUUM BREAKER SYSTEMS
• For model ES boilers P/N ES89369
• For model SSB boilers P/N SSB89369
A vacuum breaker will prevent a boiler from flooding as a result of the steam condensing internally and creating a
vacuum after boiler shutdown. The breaker allows air to enter the boiler shell breaking the vacuum. This system is
a must for boilers connected to a condensate return tank. The vacuum breaker consists of a spring-loaded disc and
associated piping and is factory plumbed to the boiler. The SSB89369 is of stainless steel construction.
AUTOMATIC BLOWDOWN SYSTEM
• Extends life of boiler
• Saves labor costs
• Starts the boiler automatically every day
• Shuts down the boiler every day
• Automatically blows down the boiler every day
• Completely programmable, can skip days, different start and shutdown times, different operational durations.
• ES81600 for all model boilers.
A stainless steel, motor driven straight-through, self-cleaning ball valve with Teflon seats handles particles and dirty
fluid without the use of an up-stream strainer or other cleaning device. A timer (Standard analog time clock is set
for two hour time intervals, optional digital time clock can be programmed to one minute intervals.) and electronic
time delay relay control the boiler and the blowdown valve. A pilot light indicates when the blowdown valve is
open. The valve shall be plumbed to a proper drain or receptacle. An automatic blowdown system can be installed
on any boiler, regardless of size operating pressure or operating duty cycle.
BLOWDOWN SEPARATORS (see page 18)
• For models ES12-48 and SSB12-48 p/n BDT-ASME36
• For models ES60-180 and SSB60-180 p/n BDT-ASME42
A separator accepts the flash steam and effluent from the boiler blowdown and reduces the temperature and pressure to insure a safe discharge of water and sludge. Steam flash and pressure are absorbed and pass harmlessly to
the outside via a vent. The separator design utilizes a water seal at the outlet, which permits the operator to introduce cold water from the bottom to mix with the hot water and boiler steam in the blowdown separator. This
reduces outlet temperature to a safe discharge level.
These separators require specific plumbing from the boiler blowdown valve and require connection to a cold water
supply. (If the separator is less than half full of water after the boiler is blown down cold water must be added to
bring the water level to the halfway mark before the next blowdown).
• 0-30 psig pressure gauge; 0-200F temperature gauge; water sight gauge glass and valve set assembly are included.
CONTROL VOLTAGE STEPDOWN TRANSFORMER
• Provides 120 Volt (220 Volt export) from main power supply. Factory wired and fused.
MULTISTAGE LOAD PROGRESSIVE SEQUENCERS
Accurate control is provided by automatic progressive sequencing in the use of energy and minimizing wear on
electrical components. The sequencers are designed to apply power progressively to larger KW boilers. A factory
installed pressure sensitive sequential control reacting to steam boiler pressure progressive energizes or de-energizes heating elements through power contactors. A delay between sequencer steps before start-up and between
each subsequent step eliminates power surges. Each sequencer is matched and factory pre- set to boiler system
requirements. Electronic progressive sequencers give accurate control of multi-stage loads of the type used in steam
boilers. Features include progressive sequencing (first on- first off) that equalizes the operating time of each load.
Integral solid-state light emitting diodes show active stages. Should a power interruption occur, all elements are
instantly de-energized for safety. Upon resumption of power the control will re-stage the loads one at a time.

6. Carefully slide upper glass packing up as far as possible.
7. Hand tighten both glass packing nuts, then tighten 1/2 turn more by wrench. Tighten only enough to prevent leakage. DO NOT OVER TIGHTEN!
If any leakage should occur, tighten lightly, a quarter turn at a time, checking for leakage after each turn.
IMPORTANT NOTE: Read all warnings and instructions before performing installation or maintenance.
!
Safety glasses and gloves should be worn at all times when working with
or examining water gauge glass and connections.

Gauge Glass Installation - Use and Care
DO NOTs
DO NOT use glass if it contains any scratches, chips, or any other visible signs of damage.
DO NOT reuse any tubular glass or glass packings.
DO NOT subject gauge glass to bending or torsional stresses.
DO NOT over tighten glass packing nuts.
DO NOT allow glass to touch any metal parts.
DO NOT exceed the recommended pressure of the gauge or gauge glass.
DO NOT clean the gauge or gauge glass while pressurized or in operation.
DO's
DO verify proper gauge has been supplied.
DO examine gauge glass and packings carefully for damage before installation.
DO install protective guards and utilize automatic ball checks where necessary to help prevent injury
in case of glass breakage.
DO inspect the gauge glass daily, keep maintenance records, and conduct routine replacements.
DO protect glass from sudden changes in temperatures such as drafts, water spray, etc.
MAINTENANCE
Examine the gauge glass regularly for any signs of clouding, scratching, erosion, or corrosion. The glass should be
inspected daily until the need for replacement becomes apparent. This will help establish the routine inspection
and routine replacement schedules.
CLEANING
Use commercial non-abrasive glass cleaners to keep glass clean. Use diluted acids such as Hydrochloric (muriatic)
acid when regular cleaners do not seem to work. Do not use wire brushes or any other abrasive materials which
could
scratch the glass.
INSPECTION
Examine the surface of the glass for scratches, corrosion, chips, cracks, surface flaws, or nicks. To do this, shine a
very bright concentrated light at an angle of about 45 degrees.A defective glass will glisten as the light strikes
imperfections. Glass which appears cloudy or roughened, and will not respond to cleaning, should be replaced.
STORING
Keep gauge glass in original packaging until ready to install.

Element Replacement
READ INSTRUCTIONS COMPLETELY BEFORE STARTING WORK
!
O N Before Installing your new elements be sure the
CAUTI
McDonnell Miller low water cut-off and aux. low
water cutoff (if supplied) is operating properly. The float chamber and
lower equalizer column of the MM control must be completely clear of
sludge or other foreign matter. Failure to do this may cause the immediate burn-out of the new elements. If the unit is probe equipped, check
condition of the probes and isolator.
Boiler with
McDonnell Miller
All elements are thoroughly checked before shipment The manufacturer
cannot be responsible for burn-outs caused by a faulty low water cut-off.
1” Steam Equalizing Pipe
Pump and Low Water Control
Normal Boiler Water Line
Cut-Off Level is Arrow Mark
11⁄2”
The lower equalizer column can best be examined by breaking the unions
on either side and then visually and manually examining the piping with
your finger or probes to see if it is clear and clean.

Torque Values:
1. Disconnect boiler from electric power supply at main safety switch or fuse panel.
Then turn boiler switch to “OFF" position.
2. Close water supply valve on incoming water supply line. Drain boiler completely of water.
3. Open boiler door to access heating element.
4. Disconnect wire (electric) leads connecting element to main power system of boiler.
Again, note wire connections to facilitate re-assembly. Proceed to remove and discard
(6) bolts from flange.
IMPORTANT: Note the wire connections to facilitate re-assembly (see wiring schematic).
Remove and discard six (5/16"-18) bolts from flange. Do not reuse these bolts.
5. Thoroughly clean boiler flange of all foreign material. Be certain no part of old gasket
remains on flange.
6. Apply "Slic-Tite" Gasket Compound (or equal) to both surfaces of new gasket supplied
with replacement element. Proceed to install element flange assembly with gasket
between boiler flange and element flange. In doing this, be careful to align flange holes
so element wire connection terminals on element assembly are in line with previously
disconnected wire leads to facilitate easy connections.
NOTE: Observe markings on element flange. Install element marking “TOP” on top.
7. Use only new element flange bolts. Tighten all (6) element flange bolts to a torque value
of 22 lb-ft each (see illustration).
8. Connect all wires to the terminals. Tighten all element terminals to a torque value of
20 lb-in each (see illustration). Make sure all wires are clean and bright to assure good
electrical contact.
9. Check that the wires are correctly connected to the contactor terminals and are tightened
to a torque value of 45 lb-in. (see illustration). Make sure all wires are clean and bright to
assure good electrical contact.
10. Open water valve to allow water supply to reach boiler feed mechanism.
11. As boiler automatically refills, observe the new flange assembly for possible leaks. If water
is noticed, the bolts must be re-tightened. Before doing this, turn the boiler off at the
main fuse safety switch.
12. When boiler reaches working pressure, check flange assembly again for leaks.

Water Quality Information for Carbon Steel Boilers
FOR OPTIMUM RESULTS, THE FEEDWATER SUPPLY SHOULD BE TESTED PRIOR TO INITIAL STARTUP, IF THE MINERAL
CONTENT EXCEEDS THE FOLLOWING RECOMMENDED LIMITS, VARIOUS EXTERNAL TREATMENT PROCESSES
(WATER SOFTENER, REVERSE OSMOSIS, ETC,) MAY BE USED TO CORRECT THE PROBLEM.
NOTE: AN ANALYSIS OF THE ON-SITE BOILER FEEDWATER MUST BE MADE BY A RECOGNIZED AND RELIABLE
WATER TREATMENT COMPANY TO ASCERTAIN THE EXISTING CONDITION AND TREATMENT REQUIRED.

WATER QUALITY CAN AFFECT EFFICIENCY OR RESULT IN BOILER DAMAGE IF NEGLECTED. BOILER FEEDWATER
CONTAINS IMPURITIES IN SOLUTION AND SUSPENSION. THESE IMPURITIES CONCENTRATE IN THE BOILER SINCE THE
STEAM GENERATED IS ESSENTIALLY PURE. THE CONCENTRATION OF THESE IMPURITIES INCREASES AS MORE FEEDWATER IS INTRODUCED INTO THE BOILER AND STEAM IS PRODUCED. IF THE SUSPENDED SOLIDS ARE ALLOWED TO
CONCENTRATE BEYOND CERTAIN LIMITS, A DEPOSIT OR "SCALE" WILL FORM ON THE BOILER INTERNAL SURFACES. THIS DEPOSIT CAN INTERFERE WITH PROPER BOILER OPERATION AND CAUSE BOILER FAILURE.
THE CONCENTRATION OF THESE IMPURITIES IS GENERALLY CONTROLLED BY THE FEEDWATER QUALITY AND BY
BLOWDOWN. BLOWDOWN REFERS TO REMOVING A PORTION OF THE BOILER WATER WITH HIGH SOLIDS CONCENTRATION AND REPLACING IT WITH MAKEUP WATER OF A LOWER CONCENTRATION.
