Model Number Key

1. Each  boiler  model  requires  two  (2)  power  supplies: Primary heating power and secondary control voltage. Nominal control voltage is 120V, 50/60Hz. Boiler models rated for 380V and 415V are equipped with control voltage transformers that require 220/240V applied to their primary side in order to provide the 120V AC control voltage to the boiler. As an option, all boiler models can be equipped with control voltage transformers so that only the heating power supply needs to be connected to the boiler.
2. Also available in 240V 1PH
3. On  boiler  equipped  with  condensate  tank,  add  90lbs (41.0kg) to shipping weight
4. The  STEAM  CAPACITY  listed  above  is  based  on  the evaporation rate from and at 212°F, at 0 psig. If the boiler feed water temperature is 50°F, then the STEAM CAPACITY for each model listed above is approximately 15% lower.
5. RX100 model, rated 208V, 3ph is limited to 307lbs/hr, 90kW, 9BHP

Location

Place the boiler in a level position, close to the equipment which it is to supply. This will insure minimum heat losses and allow more economical piping arrangements. All steam lines should be insulated. Review the overall dimensions of your boiler model on page 6 to select proper boiler location.
Regardless of the NFPA­70 working space requirements shown below, provide a minimum of 3ft clearance on both sides of the boiler for element servicing, 3ft of clearance to the front of the boiler and 1.5ft to the rear of the boiler.

• Working space:
  Electric boiler spacing is dictated by NFPA­70, Table 110.26 as follows:

Note: Where the conditions are as follows:

Condition 1 — Exposed live parts on one side of the working space and no live or grounded parts on the other side of the working space, or exposed live parts on both sides of the working space that are effectively guarded by insulating materials.
Condition 2 — Exposed live parts on one side of the working space and grounded parts on the other side of the working space. Concrete, brick, or tile walls shall be considered as grounded.
Condition 3 — Exposed live parts on both sides of the working space.

• Dead­ Front Assemblies. Working space shall not be required in the back or sides of assemblies, such as dead­ front switchboards or motor control centers, where all connections and all renewable or adjustable parts, such as fuses or switches, are accessible from
  locations other than the back or sides. Where rear access is required to work on non­electrical parts on the back of enclosed equipment, a minimum horizontal working space of 762 mm (30 in.) shall be provided.

• Alcove or closet installation per UL834: Proper location of this boiler model with regard to combustible and noncombustible surfaces and materials is coded on the boiler name plate. The following decoding sketch and description is provided for the user information:

Description of dimensions and symbols

• A – Clearance above top of boiler

• B – Clearance from front of boiler
  Prefix C to numeral indicates suitability for closet or alcove installation
  Prefix A indicates suitability for alcove but not for closet installation

• D – Clearance from back of boiler

• EL – Clearance from left side of boiler

• ER – Clearance from right side of boiler

• F – Indicates type of flooring: “NC” for noncombustible floor / “C” for combustible floor. Numeral indicates minimum clearance below suspended units to combustible floor

Water Supply

On  models  with  pump  and/or  solenoid  valve,  connect  incoming water supply to strainer on intake side of solenoid valve.

On models furnished with condensate return tank, connect water  line  to makeup  valve  located  at  tank  end.  (See  Instruction Supplement 1 in this manual) R, RH and RHC steam boiler models require four (4) gallons of feed water per hour for each 10 kW of electric heating capacity of the boiler. Lines  should  be  of  adequate  size  and  meet  local  plumbing codes.
In  order  to  ensure  long  term  trouble­ free  boiler  operation,  we recommend that the water used as boiler feed water to be tested for hardness. If the water in your area is harder than  1grain  (17mg/L),  use  a  water softener.  The  main  cause for premature heating element failure in electric steam boilers is water hardness. If severe corrosion during inspection  of the  pressure  vessel  as  indicated  in  chapter  3.4 of this manual becomes evident, additional tests of your boiler feed water must be performed. A water analysis should  be  performed  by  a  qualified  and  recognized  water treatment company located in your area.
Recommended levels for boiler feed water:

Recommended  levels  for  boiler  water  (water  inside  pressure vessel when boiler is operating)

NOTICE
Do not add any chemicals to the  boiler feed water unless specifically recommended  by  a  qualified  and  recognized water treatment company.

Steam Outlet

All  piping  from  and  to  the  boiler  must  comply  with  the  A.S.M.E. B31.1 Power Piping Code. All State and local codes must be met. All piping must be done by a qualified steam fitter.
Connect steam line of sufficient size from steam line valve to  the equipment.  Steam  piping  must  be  black  steel  pipe,  not galvanized. Work must be done by an experienced steamfitter. All state and local codes must be met.

Condensate Return

If the condensate is to be returned by gravity (no tank) in a closed system, the load discharge should be at least 2 feet above the boiler level so that the weight of the condensate will actuate the check valve. When applicable, install steam return lines at sufficient height to allow a pitch of 2 inches for every 10 feet of pipe length.

Note:   For  condensate  return  systems  (with  tank),  see  special sheet.

Safety Relief Valve

The safety valve is designed to discharge hot steam when the  set  pressure is  exceeded.  Ensure  that  the  discharge  port is pointing toward the back of the unit away from the operator  and  any  aisles.  If  it  is  required that  discharge  piping be installed from the safety valve, the pipe should not  be  smaller  than  the  valve  outlet  and  should  be  rigidly supported so as not to place weight on the valve itself.
Important: No valve in this line!

Electrical

Install a fused disconnect switch near the boiler. It should be fused as marked on the boiler name plate. Connect the power supply from the disconnect switch to the terminals in the boiler control panel. A copy of the wiring diagram is in the control panel.
Important: Electrical connections to the boiler control panel (FIG. 7)should be made by a qualified  Electrician.  All wiring must comply with local electrical codes.

Three Phase Boiler Models Without Power Supply Extension Box

Three ­Phase Boiler Models With Power Supply Extension Box

All  boiler  models  that  are  equipped  with  a  transformer  option (OPT1010 or OPT1011) don’t require a separate external control voltage power supply.

Blowdown Valve

CAUTION When the blowdown valve is utilized, a large volume of hot water and  steam  is  discharged.    Ensure  that  this  valve  is  properly piped for this discharge. State and local codes must be met as applicable.

Operation

Boiler Startup

• Open steam line valve slightly. This will allow the boiler to be filled without producing back pressure.

• Open upper and lower gauge glass fixture valve

• Ensure that the feed water shutoff valve is in the OPEN­ position

• Close the boiler blow down valve

• Throw  the  fused  disconnect  switch  (not  provided  by factory) to the ON­ position and turn on the boiler control voltage

• After approximately 2 seconds, the WATER FEED light turns on and water enters the boiler. As soon as the water level reaches approximately half height in the gauge glass, the automatic water feed turns off.

NOTICE Do  not  let  the  pump  to  run  dry  for  an  extended time as this will cause damage to the pump.

As  soon  as  no  boiler  alarms  are  indicated,  the  HEATING light turns on and the boiler starts to build up pressure. Observe the pressure gauge while pressure builds up, until working pressure is reached. The working pressure should have been factory set to your specification. However, if you wish  to  change  the  working  pressure  setting,  proceed as  follows.

WARNING Stand clear of scalding water or steam. Disconnect  the  boiler from  all  power  supplies.

All pressure controls are factory preset and require no adjustment. However, if a change of the operating steam pressure is required, then proceed as follows:

• Disconnect all power supplies from the boiler.

• Close the steam outlet valve

• Remove the cover from the pressure control enclosure.

• Turn  the  black  knob  of  the  operating  pressure  switch clockwise  to  increase  the pressure and counterclockwise to decrease the pressure.

• To  shut  off  the  boiler,  turn  the  POWER  switch  on  the  boiler controller OFF.

See Boiler Control Manual for detailed instructions.
The control provides four basic functions and two optional functions. The following overview describes the functions.

Low water cutoff
Boiler high pressure cutoff
High water level feed shutoff Automatic boiler refill Automatic boiler blow off (Optional)
Remote  controlled  boiler  ON/OFF  and  boiler  status  (Optional)

Control Functions

Low Water Cut­ Off Function
The  low  water  cutoff  function  of  the  boiler  control  de­energizes the heating elements when the water level in the boiler pressure vessel falls below the minimum acceptable operating  level.  The  control  senses  the water  level  in  the  boiler pressure vessel through a probe, E3. When the tip of the  probe  is  in  contact  with  water  in  the  boiler,  the  boiler operates normally. When the water level in the boiler falls below  the  tip of  the  probe  the  control  senses  that  water  level is low. The control will not de­energize the heating elements  when  the  probe  loses  contact with  the  boiler  water for short periods of time. But, when the probe loses contact with the probe for a set time, the control de­ener­gizes  the  heating elements  and  turns  on  the  “LOW  WATER” boiler alarm light. Boiler operation can only be resumed after determining why water level is low, restoring normal  water  level  in  the  boiler  and  pressing  the  “LOW WATER” reset button [R]. After presiding the “LOW WATER” reset button the alarm light “LOW WATER” turns off,  the  lockout  is  reset  and  the  heating elements  are  energized.
The Low Water Cut­ Off function short cycling timer can be adjusted. See the Boiler Control Manual (Doc. #9101)

High Pressure Cutoff Function
If  the  operating  pressure  control  fails,  the  steam  pressure  in the boiler can reach the value set on the high limit pressure  control.  In  that case,  the  high  limit  pressure  control de­energizes the heating elements and locks them out. The boiler alarm light “HIGH PRESSURE” comes on. After the  pressure  control  is  replaced  the  HIGH  PRESSURE alarm light turns off.

High Water Level Feed Shutoff
When the high water level cut­off probe (E2) comes in con­ tact with boiler water, the boiler control turns off the auto­ mastic refilling device, feed pump and/or solenoid valve. At the same time the boiler controller de­energizes the heat­ing elements, closes the steam outlet line through the sole­ node valve (SOL2) and displays a flashing “2” on the LED display. As soon  as  the  probe  E2  looses  contact  with  the  boiler water the boiler controller resumes normal boiler operation automatically. (The boiler controller can be set to require that the “E­ Key be pressed to resume boiler oper­ation. See the Boiler Control Manual for instructions.)

Automatic Boiler Refill
When the POWER switch is turned on and the water level probe  (E1)  is  in contact  with  the  boiler  water,  the  boiler  control keeps the boiler water feed pump and/or solenoid valve de­energized. When the water level probe (E1) loses contact  with  the  boiler  water,  the  boiler  control  energizes the boiler feed pump and/or the solenoid valve after a set ON delay time. When the water level probe makes contact with the boiler water, the boiler controller de­energizes the boiler water feed pump and/or solenoid valve after a set re­fill OFF delay time.
The  ON  and  OFF  delay  time  can  be  adjusted. See the boiler control manual for instructions.
If the feedwater pump and/or solenoid valve remains on for longer than the ON delay time the boiler control de­energizes the feed water pump and/or solenoid valve and dis­  plays a flashing  “0” on the control LED display.  The “E” ;key must be pressed to start a new re­filling attempt

Automatic Boiler Blowoff (Optional)
See Boiler Control Manual for instructions.

Remote  controlled  boiler  ON/OFF  and  boiler  status. (Optional)
See Boiler Control Manual for instructions.

Boiler Monitor Definitions

The  following  are  definitions  for  all  boiler  monitor  indications. See the control manual for details including adjusting all pa­rameters.
Flashing  “0”:  Boiler  feed  pump  and/or  solenoid  remained  energized longer than the set time. Boiler feed pump and/or solenoid are de­energized. Press “E” key to re­set alarm and start a new re­filling cycle.
Flashing “1”: Following a blowdown cycle, the automatic re­ fill device did not stay on for the set time. Press” E” key to re­set the alarm.
Flashing “2”: The high water level probe (E2) has come in to contact with boiler water. The feed pump and or solenoid is  de­energized  and  the heating  elements  are  de­energized. As soon as the probe (E2) loses contact with the  boiler  water  normal  control  operation  resumes.  (This  function may be set to require re­set using the E key.)

Boiler Maintenance

WARNING   Boiler  repairs  must  be  performed  by  experi­enced personnel only. Ensure boiler water is cold and drained and that there is no pressure and all electricity to the boiler is shut­off.

Boiler Blow off

All  boilers  must  be  blown  off  periodically  to  remove  minerals, scale and other foreign matter, which accumulate inside  the  pressure  vessel.  The concentration  of  this  deposit depends in part upon the condition of the water in the  area.  When  water  is  naturally  soft,  or  has  been softened chemically, boiler blow offs are required less often than  in  areas where  hard  water  is  found.  Water  softeners  are suggested in hard water areas to minimize the formation of hard scale on heating elements. Another factor affecting  water  condition  is  the  amount  of  condensate,  if  any, that is being returned to the boiler. Since condensate is  essentially  clean distilled  water,  it  contains  very  few  impurities. If a large part of the condensate is being returned and little make­up water is used, the boiler need not be blown down as often as when little or no condensate is  returned  to the  boiler.  We  recommend  blow off  of  newly  installed steam boilers once per day until the first heating element and pressure vessel inspection is performed (refer to  chapter  3.4).  If  no  significant  amount  of  sediment is  found on the bottom of the pressure vessel and on the heating element sheaths, then the boiler blow off frequency can be reduced accordingly. The safest method to blow off R­ series  steam  boilers  is  to  install  a Reimers  Electra  Steam, Inc. properly sized and fully trimmed blowdown tank, model  BTANK­10  (Figures  10  and  11).  Reimers  blowdown tanks are designed and constructed to Section VIII  of  the  A.S.M.E.  Code  and  inspected  by a commissioned National Board Boiler inspector.

Boiler Blow off Frequency
In areas where water is soft or has been softened chemically:

• When little condensate is returned blowdown once every second day
• When a large part of the condensate is returned and little make­up water is used, blowdown once every week

In areas where hard water exists:

• When little or no condensate is returned, blowdown once a day
• When a large part of the condensate is returned and little make­up water is used, blowdown once every second day

Safety Valve Test

WARNING
Stand clear of scalding water or steam. Ensure  that  the  Boiler  Bottom Blowoff  Valve is properly piped.

This test should be performed once per month. Proceed as follows:

• Increase  the  steam  pressure  as shown in chapter 2.1. to maximum operating pressure.
• Keep  the  steam  outlet  valve closed
• Pull the trip lever and hold open for five (5) seconds in order to flush off the valve seat.
• Permit the valve to “slap” shut. If a leak occurs, repeat this test and if necessary, replace the valve.

Element Replacement and Element Cleaning

WARNING
Ensure  that  the  boiler  is  cold,  drained  and all power supplies are disconnected

Clean the element rods every six (6) months. To clean the element rods, or if an element must be replaced, proceed as follows:

• Remove the element terminal cover from the front of the boiler.
• Disconnect and label the terminal wires
• Remove all four (4) nuts from each element flange and pull out the heating element

• Use a stiff  wire brush to remove all scale and foreign matter from the element rods.
• Clean the element flange surfaces before installing new elements and gaskets

Gauge Glass Replacement

WARNING: Ensure that the boiler is cold, drained and all power supplies are disconnected

Steam  and  boiler  water  can  erode  the  glass.  Therefore  inspect the sight glass every 6 months. If the glass thickness becomes less that 5/16” or if the glass looses its transparency, replace it immediately.
To  replace  the  bull’s  eye  water  level  indicator,  use  a  2­13/16” hex socket or adjustable wrench with the same minimum opening.
Read carefully the bull’s eye water level indicator manual in Instruction Supplement #2.

Troubleshooting

Ensure that the boiler is cold and has no pressure.
Electrical trouble shooting must be performed by a qualified electrician.

If trouble shooting did not resolve problem, please contact our service technicians at:
