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 2 and 3 and Code requirements.
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.
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.
6.
SSB Boilers have Stainless Steel all wetted metal parts. SSB boilers shall be operated using only deionized water, having a maximum conductance of 1 microSiemen per cm (1 µS/cm) [minimum specific resistivity of 1 megohm per cm (1ΜΩ/cm)].

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.
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.

CAUTIO N
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. 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.
Substitution of components or modifi­cation of wiring system voids the warranty and may lead to dangerous operating conditions.

Pressure Controls, Operation and Testing
Note:
All boilers are provided with one high limit pressure control and at least one operating pressure control.
1.
The high limit pressure control is equipped with a manual reset feature. There is no subtractive differential scale with this type of control
2.
All pressure controls are equipped with an adjusting
screw, allowing for setting of desired operational and high limit pressures. To reduce pressure setting, turn adjusting screw in direction that allows indicator to point to a lower pressure setting on the scale. To increase pres­sure setting turn adjusting screw in direction that allows indicator to point to a higher pressure on the scale
Note:
It is recommended that the high limit control be set
10psig above the desired normal operating pressure.
3.
Operating pressure controls, have a separate differential
scale. Differential indicates pressure below the main operating maximum pressure, the pressure control will re-set. The differential set point is adjusted in the same manner by turning the adjusting screw in the desired direction to increase or decrease the differential pressure value.

Pre-Operation Check (All Boilers)
LWCO/PUMP CONTROL OPERATION AND TESTING
1.
All valves for incoming water supply are to be fully opened. 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 operating water level and the pump/solenoid will be de-ener­gized. Contactors will then energize, applying voltage to the heating elements.
2.
Pump switch operation – at this point water should be visible approximately half way up the sight glass. Slowly open the drain valve located at the bottom of the boiler. Water level in the sight glass will begin to drop, allowing the low water cut off/pump control to energize the feed water system. Close valve for proper operation.
3.
Low water cutout switch performance – open the drain valve completely. Maintain this condition until water level falls within the gauge glass enough to cause the low water cutout switch to de-energize the heating elements. All of the contactors will be in a de-energized or open state at this time. Close the drain valve, water feed system will automatically refill the boiler and the contactors will re-energize.
Boilers equipped with an auxiliary low water cut-off control with a manual re-set button (required as mandatory equipment is some states): once the correct operating water level has been reached, it will be nec­essary to depress the reset button in order for the con­tactors to re-energize.
Note:
For boilers equipped with an automatic
blowdown system:
• For test 1 - the blowdown time clock must be in the
“run” mode before the boiler will automatically fill.
• For test 2 and 3 - in order for the drain valve to open
the blowdown clock must be in the “off” mode. (See blowdown time clock insert) The automatic blowdown indicator light will be on when the valve is open. This light will remain on for the duration of the blowdown cycle (a few seconds). It may be necessary to cycle the time clock from the “run” to “off” mode several times.
4.
Operating pressure control check: Close steam outlet
valve [supplied by customer] and adjust operating pres­sure control to 20psig and the differential to 10psig. Set the high limit pressure control to 30psig. Switch boiler on to allow steam pressure to build-up. Pressure gauge reading will increase and the operating pressure control will de-energize the contactor(s) when the pres­sure gauge indicates 20psig. Open steam outlet valve to bleed off pressure. When the pressure gauge read­ing decreases below 10psig (differential) the operating pressure control will re-energize the contactor(s).
5.
High limit pressure control check: FOR TEST PURPOSES
ONLY! Set the high limit pressure control 10psig lower
than the operating pressure control. Close the steam outlet valve and switch the boiler on to allow boiler to build pressure. When the pressure gauge indicates the pressure at which the high limit pressure control is set, the high limit pressure control re-set button will pop­up and the control will de-energize the contactor(s). Open the steam outlet valve to bleed off pressure. The contactor(s) should not re-energize on pressure drop. The contactor(s) should only re-energize when the pres­sure has dropped and the high limit pressure control reset button is depressed.

Operation
With main disconnect “OFF” tighten all electrical connections before ener­gizing boiler to prevent arcing, carbonizing of contact and/or overheating
1.
Set the desired operating pressure and differential pressure
on the operating pressure control.
2.
Set the high limit pressure control. (Recommended to be 10
psig above the operating pressure setting.)
3.
Turn on water supply.
4.
Turn main disconnect switch on.
5.
Turn boiler control switch on. The water feed will begin and
continue until the water level reaches half way up the gauge glass. The water feed will automatically shut off and the con­tactor(s) will energize.
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.
MANUAL BLOWDOWN INSTRUCTIONS
1. At the end of the working day, while boiler is still
operating, turn boiler main switch to the “OFF” posi­tion, close water supply valve and open disconnect switch.
2. If blow down valve is plumbed into a blowdown tank, the boiler can be discharged at operating pressure.
3. If the blowdown valve is not plumbed into a blow­down tank, consult with local plumbing codes regard­ing boiler discharge.
4. When discharge is complete and boiler is drained, close the blowdown valve, open the water supply valve, turn boiler main switch to “ON” position and close disconnect switch.
5. When refilling is complete, turn off the boiler unless further operation is needed.
6. If boiler is equipped with a “Manual Re-set Auxiliary Low Water Cut-off” (as required in some states) the re-set button must be pushed before the boiler will begin developing steam. Do not push re-set button until the boiler has refilled with water.
AUTOMATIC BLOWDOWN INSTRUCTIONS (PN ES81600) 1” NPT, Starts, stops and blows down the boiler auto-
matically, utilizing a programmable time clock a time-delay relay and motorized ball valve.
If the blowdown valve is plumbed into a blow­down tank, the boiler can be discharged at operating pressure. If the blowdown valve is not plumbed into a blowdown tank, consult with local plumbing codes regarding boiler discharge.
NOTE:
The manual valves from the boiler drain and the lower float control equalization tube must be fully open for the automat­ic blowdown to be effective.
1. Program time clock by setting the time boiler is to turn on and off daily. (Refer to instructions in time clock insert.)
2. When the time clock turns the boiler “off” the blowdown is acti­vated. A red pilot light over the time clock will come on and remain on while the motorized ball valve is open. The time dura­tion the valve is open is set by an adjustable potentiometer built into the time delay board. The water level in the boiler after blowdown is complete, will be approximately at the lower gauge glass valve. (Elements are not exposed to air between operations.)
3. Boiler will automatically refill at next programmed on cycle.
Blowdown program can be overridden to allow for unscheduled blowdown or operational cycles. Refer to the time clock instruction insert.
6.B
oiler steam pressure will gradually increase to the operating pressure control set point, at which time the contactor(s) will de-energize.
7.
With steam demand, the boiler steam pressure will
decrease. When the boiler pressure has dropped below the operating pressure control differential set amount, the contactor(s) will re-energize.
8.
The boiler is equipped with float type liquid level con-
trols employing micro switches. They are extremely sensitive and reliable and will maintain the proper water level within the boiler pressure vessel automat­ically during boiler operation.
9.
The boiler should be blown down daily. (See blow-
down instructions.)

24-Hour and 7-Day Time Switches
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 maintenance per­son or engineer familiarize themselves with these simple rules.
1.
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.
2.
The sight glass should be checked frequently to assure the
boiler has adequate water.
3.
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.)
4.
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.
7.
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.
8.
A monthly check for leaks should be made; any loose or
damaged fittings should be tightened or replaced.
9.
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.
10.
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.
PROGRAMMING
F
or electric steam boilers equipped with Automatic Blowdown Systems ES 81600, refer to the fol­lowing instructions for time clock operation and settings. Timer settings for blow
-
down operation are at
the discretion of the owner/operator.
The weekly program dial shows the seven days of the week and AM/PM imprints for each day.
The time switch is set by pushing the captive trippers to the outer ring position for the entire period that the load is to be turned ON, i.e., 2 hours to each trip­per on the 7-day dial. When the tripper is pushed to the inside, the switch is in the OFF position.
SETTING TIME
To set the current time and day of week, turn the minute hand clockwise. Do not set the time by rotating “Outer” Dial.
Turn the minute hand clockwise until the day of the week and the time of day on the outer dial is aligned with the triangle marker on the inner dial (two o'clock).
Example for 7-day program dial Monday 10:30 AM.Turn the minute hand clockwise until Monday 10:30 AM is aligned with the triangle on the inner dial.The hour and minute hand will show exactly 10:30.
FOR MANUAL OVERRIDE
Manual override can be accomplished at the discretion of the owner/operator as follows.
3-WAY MANUAL OVERRIDE SWITCH
I = permanent ON
I
= automatic
O = permanent OFF
O
IMPORTANT: It is recommended that for periodic and effective blowdown,the override switch be set in the automatic setting.

AUXILIARY LOW WATER CUT OFF
• For model SSB boilers SSB81017MR (with 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 SSB boilersPNPN 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 PN SSB99117 components are of stainless steel con­struction.
HIGH PRESSURE WATER FEED SYSTEM
• For model SSB12-72 PN SSB38002
• For model SSB100-180 PN SSB38020 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.
• 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.
• 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. SSB38002 and SSB38020 pump components are 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.
• SSB81600 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 14)
• For models SSB12-48 PN BDT-ASME36
• For models SSB60-180 PN 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.

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. Pressure in gener­ator to be at zero before proceeding. Improper instal­lation or maintenance of gauge glass and connections can cause immediate or delayed breakage resulting in bodily injury and/or property damage.
1.
Apply Teflon tape or pipe dope to pipe threads. Install top gauge fitting (fitting without a drain valve) into the uppermost tapping. Wrench tighten the fitting until it is snug and the glass outlet is pointing at five o'clock (about 1/8 turn from its final downward vertical position).
2.
Install the bottom gauge fitting (the fitting with a drain valve) until it is snug and the glass outlet is pointing directly upward. Verify top and bottom fittings are threaded into the tappings the same number of turns (distance A= distance B).
3.
Remove glass packing nut, friction washer (or pack­ing gland, depending upon the model), and glass packing from the fittings, and place them, in the same order, on to both ends of the gauge glass. Push both packings about an inch up the gauge glass.
4.
Gently insert one end of the glass into the top gauge fitting. Keeping the glass inside the top fit­ting, gently rotate the top gauge fitting clockwise until vertically aligned with the bottom gauge, then insert glass into bottom fitting until glass bot­toms out on the shoulder inside the bottom fitting.
5.
Carefully raise glass about 1/16" and slide lower glass packing down until the glass packing contacts the lower gauge fitting. DO NOT allow the glass to remain in contact with any metal!
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.

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. 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.

READ INSTRUCTIONS COMPLETELY BEFORE STARTING WORK
Before Installing your new elements be sure the low water cut-off and aux. low water cutoff (if supplied) is operating properly. The float chamber and lower equalizer column of the liquid level 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.
All elements are thoroughly checked before shipment The manufacturer cannot be responsible for burn-outs caused by a faulty low water cut-off.
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.
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.
Follow maintenance instructions provided with the boiler.
