OPERATING INSTRUCTIONS
CAUTIONS: READ ALL INSTRUCTIONS BEFORE INSTALLATION/OPERATION.
VALVES/PIPES ARE HOT WHEN UNDER PRESSURE OR HEATING UP - DO NOT TOUCH.
ADJUSTMENTS:
All controls have been set at the factory and should require no adjustments.
MODIFICATION/MISUSE:
Any modification or misuse of this unit could result in a dangerous situation.
Reimers is not liable for any product that has been modified or improperly used.
REGISTRATION:
Most states/cities require boiler registration/inspection. Check local regulations.
REPAIR:
Repair of this unit must be attempted only by experienced personnel. (See Enclosed)
WATER:
All boilers must be blown down periodically to remove minerals, scale and other foreign matter
which accumulate inside the pressure chamber. The concentration of this deposit depends in part
upon the condition of the water in the area. When water if naturally soft, or has been softened
chemically, blowdowns 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 make-up water is
used, the boiler need not be blown down as often as when little or no condensate is returned to
the boiler.
Chemical water treatment is not recommended for this design of electric boiler.
*For details, contact a water softening company in your area.
BLOWDOWN IS AN ESSENTIAL PART OF BOILER OPERATION.
IT IS THE BEST PREVENTIVE MAINTENANCE YOU CAN GIVE YOUR BOILER.
ENSURE A BLOWDOWN SCHEDULE IS ESTABLISHED & FOLLOWED REGULARLY.
WATER LEVEL CONTROLS MUST BE KEPT CLEAN TO INSURE PROPER OPERATION. SINCE WATER QUALITY
CAN VARY, WATER LEVEL PROBES MUST BE INSPECTED AND CLEANED PERIODICALLY. WE SUGGEST EVERY
THREE MONTHS AT A MINIMUM. (.5” PLUGED HOLE HAS BEEN PROVIDED IN HEAD OF BOILER TO ASSIST IN
PROBE MAINTANCE).
INSTALLATION

1. LOCATION: Place boiler in a level position as close as possible to the equipment to be
supplied with steam. This will allow short steam connections and minimum heat losses. Cover
all steam lines with insulation. Ensure that all electrical components are in a dry location not
subject to steam or water. IMPORTANT:
If installing the boiler in a confined area, leave the following clearances for servicing elements.
Other installation dimensions are referenced on enclosed "RECOMMENDED BOILER
INSTALLATION PARAMETERS" sheet.
(A) Allow 24" clearance at element end for servicing of Models 10 thru 30.
2. 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.
3. STEAM OUTLET: Connect steam line of sufficient size from steam line valve to the
equipment. Steam piping must be of black pipe, not galvanized. Work must be done by an
experienced steamfitter. All state/local codes must be met.
4. CONDENSATE RETURN: If the condensate is to be returned by gravity (no tank & no
steam trap) in a closed system, the load discharge should be at least 2 feet above the boiler
water level. When applicable install steam return lines at sufficient height to allow a pitch of 2
inches to 10 feet of pipe length. To make the return connection to boiler, remove the boiler blow
down valve install a tee and a close nipple and replace the blow-down valve, connect the return
line with a swing check valve to the side opening of the tee with flow towards the boiler.
Where a significant amount of intermittent live steam is being taken from a line over 25 to 30 ft. in
length, this system is not recommended.
5. CONDENSATE RETURN SYSTEM (WITH TANK): See Instruction Supplement #1.
6. SAFETY VALVE: 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 & any aisles. If it is required that discharge piping be installed from
the safety valve, the pipe must never be smaller than the valve outlet & must be rigidly supported,
placing no weight on the valve itself.
7. ELECTRICAL: All wiring must be installed in accordance with the National Electric Code &
any local codes that may apply. Wiring must be done by a competent, certified electrician. For
this service, the N.E.C. requires supply wires rated at 125% of full load. Use only copper wire.
Install a fused disconnect switch within sight of the boiler. Connect power supply to the terminals
in control panel .
8. BLOWDOWN VALVE: When the blowdown valve is utilized a large volume of hot water
& steam is discharged. Ensure that this valve is properly piped for this discharge. State and
local codes must be met as applicable.
OPERATION
1. Close the boiler drain valve, open gauge glass valves, top and bottom, & open steam line
valve slightly to allow air to escape.
2. Turn on main water supply. CAUTION:
Be sure water supply line to boiler is OPEN before turning on main power.
On models furnished with pump, never let pump run dry.
3. Throw main disconnect switch (main power supply) and toggle switch to ON position. This
allows water to enter the boiler. On all models the water will automatically shut off when the water
reaches the proper operating level.

4. Push low water manual reset switch. This turns on power to the heating elements. Now close
the steam valve to allow pressure to build up.
5. When boiler has reached working pressure, open steam valve slowly by making 2 or 3 half
turns during a period of about 2 minutes, then open the valve fully. Keep this valve open while
boiler is in operation.
PRESSURE ADJUSTMENT: Turn knob on pressure control (located to the left rear of the
electrical box) clockwise to increase & counterclockwise to decrease. Be careful that safety valve
does not lift.
6. TO SHUT OFF BOILER: Turn the toggle switch to the OFF position. Throw main power
supply disconnect switch to OFF. Leave steam line open allowing pressure to drop normally and
boiler to cool off slowly.
MAINTENANCE
CAUTION:
REPAIR MUST BE BY EXPERIENCED PERSONNEL.
ENSURE BOILER IS COLD/DRAINED AND HAS NO PRESSURE/ELECTRIC.
ALL ELECTRICAL/STEAM SAFETY PRECAUTIONS MUST BE TAKEN.
1. BLOWDOWN:Turn power off, allow pressure to drop to 5 psig, & open each blowdown
valve for approximately ten (10) seconds.
CAUTION: STAND CLEAR OF SCALDING WATER/STEAM. ENSURE BLOWDOWN SAFELY PIPED.
FREQUENCY:
IN AREAS WHERE WATER IS SOFT OR HAS BEEN SOFTENED CHEMICALLY:
a. When little condensate is returned BLOW DOWN ONCE EVERY WEEK.
b. When a large part of the condensate returned and little make-up water is used
BLOWDOWN ONCE EVERY TWO WEEKS.
IN AREAS WHERE HARD WATER EXISTS:
a. When little or no condensate is returned BLOW DOWN ONCE A DAY.
b. When a large part of the condensate is returned and little make-up water is used
BLOWDOWN ONCE EVERY WEEK.
2. PRESSURE ADJUSTMENT: (FACTORY PRESET/SELDOM REQ'D)
CAUTION: STAND CLEAR OF SAFETY VALVE & SCALDING STEAM.
3. SAFETY VALVE TEST: (FREQUENCY-MINIMUM ONCE PER MONTH)
CAUTION: STAND CLEAR OF SAFETY VALVE & SCALDING STEAM.
NOTE: Safety valve should be tested at max.operating pressure.
1. Hold trip lever open for five seconds in order to flush off valve seat.
2. Permit valve to "slap" shut.(If leak occurs, repeat test or replace valve.)
4. ELEMENT TEST: (CONDITION) Unit will not heatup/maintain pressure, when
power is on, unit is filled with water & pressure control is calling for steam.
1. VOLTAGE TEST = read rated voltage across each element. If no voltage reading,
CHECK VOLTAGE BEFORE & AFTER EACH FUSE AND CHECK CONTROL VOLTAGE
READING AT CONTACTOR. If voltage reads properly, GO TO STEP 2.
2. AMPERAGE TEST = read rated amps on each element wire. If no amp reading or
unbalanced amp reading, replace element.
5. ELEMENT CLEANING: Use stiff wire brush & remove all scale/foreign matter.
6. ELEMENT REPLACEMENT:

CAUTION:ENSURE BOILER IS COLD/DRAINED & HAS NO PRESSURE/ELECTRIC
1. Open front cabinet door.
2. Disconnect and label terminal wires.
3. Remove 4 nuts from element flange and pull out heating element.
4. Clean flange surface before installing new element & gasket.
7. CONTROL CIRUCIT TEST: (CONDITION)Unit will not heatup when power is on,
unit is filled with water & pressure control is calling for steam.
VOLTAGE TEST = read control voltage at incoming control ciruit fuse & at each control
point throughout system, i.e. low water control, hi-limit pressure control, operating pressure
control (or step control if equipped), aux. low water cutoff (optional), and toggle switch. If voltage
is not found at any one item in system, check out that item.
8. GAUGE GLASS REPLACEMENT: (FREQUENCY = MINIMUM ONCE PER YEAR)
CAUTION: ENSURE BOILER IS COLD/DRAINED & HAS NO PRESSURE/ELECTRIC.
BE CAREFUL NOT TO BREAK GLASS
1. Close gauge glass valves (top and bottom).
2. Open petcock on bottom fixture of drain glass.
3. Loosen nuts at top and bottom of glass.
4. Slide glass up, pull out on bottom of glass and remove.
5. Install glass by reversing above procedure.
NOTE: Always install new rubber washers.
9. WATER FEED & LOW WATER CUTOFF:
1. Boiler does not take water: Check valve from city water & strainer clogging.
2. Boiler floods(cold water feed): Check solenoid for sticking.
3. Evaluate circuit board.
CAUTION: USE ONLY INSULATED ELECTRICAL WIRE FOR JUMPER.
DISCONNECT ELECTRICAL POWER WHEN ATTACHING JUMPER OR CLEANING PROBE.
LEFT LED: Indicates pump/solenoid is on when lit. If water does not feed when LEFT LED is lit,
investigate pump/solenoid. If LEFT LED does not light when water in boiler is low, remove probe
wire from terminal H. If light comes on, clean probe connected to H wire. If this does not resolve
problem, replace circuit board.
RIGHT LED: Indicates ample water in boiler for element operation when lit. If element does not
energize when RIGHT LED is lit, investigate electrical control circuit (pressure controls, fuses,
contactor, etc.). If RIGHT LED does not light when water in boiler is over half full & manual reset
has been pushed, jump terminals LLCO & G with insulated ground wire. If light comes on, clean
probe connected to LLCO wire. If this does not resolve problem, replace circuit board.
10. PUMP MOTOR: Maintenance is not normally required on the pump or motor.
11. FUSE FAILURE: When a fuse blows, evaluate the following:
SHORT CIRCUIT HAS OCCURRED: Ensure line has been cleared, the cause of short
circuit removed, then install the new fuse.
POOR CONTACT EXISTS: Poor contact on fuse can cause blowing. If surface that
makes contact with the fuse clips is discolored, fuse has been making poor contact with the clips.
Installing a larger fuse will not help. Replace the fuse holder.
12. FUSE REPLACEMENT:
1. DO NOT insert the fuse in live circuits, that will cause an arc that would cause a burr on the
fuse cap which will prevent good contact with the clips.
2. If the insides of the clips and/or fuse caps are not bright and clean, brighten them with
emery cloth.
3. If the fuse can be easily inserted into the spring clips or can be easily rotated after it is
inserted, there is not sufficient contact pressure. Take the fuse out and draw the clips together.

4. If the clips have lost their spring, they should be replaced or clip clamps should be
used. #1 for 0-30 amp/250 volt; #2 for 35-60 amp/250 volt Even if clamps are used be sure that
the insides of clips are bright & clean.
13. CONTACTORS:
1. Ensure contactor coil is receiving proper voltage. The req’d voltage is stamped on the coil.
2. If voltage to coil is present, but contacts won't pull in, replace coil.
3. If contacts pull in, but contactor chatters: CLEAN/REPLACE CONTACT POINTS.
4. Further problems would indicate mechanical difficulties within the contactor (ie: springs,
component parts).
5. Complete contactor replacement is normally the least expensive solution.
