PER Series 3 Electric-Hydronic Boilers Installation Instructions
Pre -in s t a lla t io n
General instructions
Expansion tank sizing
Undersized expansion tanks cause system water to be
lost from relief valve and makeup water added through
fill valve. Eventual section failure can result.
The Weil-McLain Model PER electric-hydronic boilers
are assembled units designed for use in forced hot water
heating systems. The suggested design temperature rise
through the boiler is 20°F. The PER boiler is a complete
package including the circulator and expansion tank.
Low flow rates through the boiler at elevated
temperatures should be avoided. The structure to be
heated should be insulated in the conventional manner
used in your area for electrically heated buildings. Boiler
must be installed in accordance with these instructions
so as not to void our warranty.
If a Fill-Trol system is used, refer to Table 1 for proper sizing. If Fill-Trol
action is not desired,size the expansion tank according to the water volume
of the system. If a standard closed expansion tank (without a diaphragm)
is used, the air vent tapping on the boiler casting makes a convenient point
of connection. The No. 109 Fill-Trol is furnished as standard equipment.
Open the boiler crate and check the contents. In the
event of shortage or damage, notify the transportation
company immediately.

Allow sufficient clearance above and below the boiler
cabinet to permit installation of supply and return
piping.A minimum of 6 inches is required at the top of
the boiler for installation and accessories. A clearance
of 10 inches is required on the right hand side for
removal of the elements.
Note: Gravity systems converted to a forced hot water system usually require
additional compression tank capacity.
Mounting the boiler
Hydrostatic pressure test
Normally, the boiler will be installed against a frame or
masonry wall. If the wall surface is rough or uneven, it
may be necessary to mount plywood on the wall, then
mount the boiler on the plywood. Refer to
“Dimensions”on page 12 and“Ratings”on page 13,and
note the boiler weight. Be sure that the wall structure
will support the boiler and its piping.
The 9/16" top mounting holes and 5/16" lower mounting
holes are on 16-inch centers to permit installation on
studs in standard wall construction. The use of ¼" x
2½" lag screws is recommended for mounting the boiler.
The head diameters of the top two screws must not
exceed 9/16".
1. Locate the top mounting holes so that the boiler
will be level. Install the screws so that the heads
protrude ¾" from the wall.
2. Raise the boiler to mounting position by placing a
board across the bottom of the boiler or by grasping
the lower left and right inside corners. Do not
attempt to lift the boiler by grasping the bottom
jacket cross tie.
Pressure test boiler before attaching piping or electrical supply.
1. Install air vent in tapping on top of boiler.
2. Plug remaining tappings, including relief valve opening.
3. Connect water supply. Fill boiler and purge all air. For more than 10
minutes, pressure-test at 1½ times maximum working pressure.
Do not leave boiler unattended. Cold water fill could
expand and cause excess pressure, resulting in severe
personal injury, death or substantial property damage.
4. Check for maintained gauge pressure. Visually check for leaks if gauge
pressure drops.
5. Drain boiler and repair leaks if found.
Leaks must be repaired at once. Failure to do so can
damage boiler, resulting in substantial property damage.
6. Retest boiler after repairing leaks.
7. Remove testing plugs and air vent.
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to boiler
will result, causing substantial property damage.
3. Place the top brackets over the lag screws and then
install screws through the lower mounting holes.
The top screws can now be tightened.

Piping the boiler
After the boiler is secured to the wall, attach the supply
and return piping. Refer to Table 2 for minimum pipe
sizes.
Install manual shut-off valves in the supply and return
lines to facilitate servicing the boiler. Model PER boilers
are provided with a built-in air elimination system using
a float-type automatic air vent. Refer to the boiler line
drawings and proceed as follows:
1. Install the pressure-temperature gauge and ¾"-¼"
bushing in the 1¼" x 1¼" x ¾" tee installed on the
boiler supply connection. See “Dimensions” on
page 12.
Wiring the boiler
Electric shock hazard. Can cause
severe personal injury or death if
power source, including service
switch on boiler, is not disconnected
before installing or servicing.
The Model PER electric-hydronic boilers are pre-wired
for use with 240-volt, single phase, 50/60-hertz power.
Refer to Figure 1 on page 13 for the reduction in boiler
capacity when the line voltage is less than 240 volts.
An opening is provided in the left side of the jacket top
panel for the field wiring. Refer to Dimensions, page
12, and Ratings, page 13, for recommended wire sizes.
2. The ¾" tapping, located to the left of the supply
tapping, must be used for either an automatic
venting device or piped directly to a standard closed
expansion tank.
3. Install the pressure relief valve in the ¾" tapping
located on the top left hand side of the boiler (see
“Dimensions” on page 12). Pipe the relief valve
outlet to a floor drain or near the floor. Do not pipe
the relief valve to any area where freezing
temperatures might be encountered.
All wiring must conform to the requirements of the
National Electrical Code and any additional National,
State or Local Code Requirements having jurisdiction.
All safety circuit wiring should be N.E.C. Class 1. Do
not use aluminum wire.
When a PER boiler is used in a zoned system, the zone
valves must be powered from an independent source,
and have electrically isolated end switches or isolating
relays wired in parallel to the boiler thermostat
terminals.
Pipe relief valve discharge line near
floor close to floor drain to eliminate
potential of severe burns. Do not
pipe to any area where freezing
could occur. Do not plug valve or
place any obstruction in discharge
line.
Do not attempt to power zone valves
from the transformer in the boiler
control system.

Call for heat
1. The thermostat contacts close, energizing the first contactor (2K), the circulator relay
(1K), and the heater in the first thermal time delay (H1).
2. Approximately 15 seconds later, the thermal delay contacts (1C) close energizing the
electronic circuit inside the first electronic time delay (ED1).
3. After approximately 2.5 minutes, the first electronic time delay energizes the second
contactor (3K) and the second thermal time delay heater (H2).
4. This sequence continues until all contactors are energized or until the call for heat ends.
Call for heat satisfied
5. The thermostat contacts open, de-energizing the first contactor (2K), the circulator relay
(1K), and the heater in the first thermal time delay (H1).
6. After a minimum of 10 seconds,the contacts in the first thermal delay (1C) open, instantly
de-energizing the electronic time delay (ED1), the second contactor (3K), and the second
thermal delay heater (H2).
7. This sequence continues until all elements are de-energized.
Limit control operation
8. If the high limit setting is exceeded, the transformer secondary circuit is opened and all
contactors are de-energized instantly. It is recommended that the“high”side of the control
be set at 220°F. The “low” side should be set according to the design requirements of the
structure to be heated but never less than 20°F below the “high” setting. The differential
control should be set at a minimum of 20°F.

PER Series 3 Electric-Hydronic Boilers Installation Instructions
Tro u b le s h o o t in g
This boiler contains fiberglass materials. Use care when handling these materials per instructions on page 11 of
this manual. Failure to comply could result in severe personal injury.
Symptom—No heat
1. Check fuses. Power for the control circuit is supplied through the fuses
for the heating element, and the circulator.
2. If fuses are good,jumper the thermostat terminal. If boiler starts, check
the thermostat and associated wiring.
3. If thermostat and wiring are good, check the limit control.
Symptom—Boiler does not shut
down
One or more contactors remain on after call for heat
ends.
1. Check contactors. Lower the temperature setting
on“high”side of the limit control to simulate a limit
operation.
a. Jumper the“R”and “B”terminals on the“low”side of the control.
If the boiler starts, replace the limit control.
b. If the boiler does not start in step“a”, momentarily jumper the“R”
and “B” terminals on the “high” side of the control. If the boiler
starts, replace the limit control.
a. If all contactors instantly de-energize, they are
good.
b. If one or more contactors fail to de-energize,
replace those contactors.
4. If the limit control is good, check the transformer.
a. Measure the A.C.voltage on the transformer. If theA.C. voltage is
24 volts ± 15%, the transformer is good.
2. If contactors are good, check the thermal delays.
Return the temperature setting on the “high” side
of the limit control to its original position. Allow
the boiler to sequence on with a normal call for
heat. When all contactors are energized, lower the
setting on the “low” side of the limit control to
satisfy the call for heat. Observe the shutdown
sequence and note the contactor at which it stops.
Remove the wire connecting terminal 1 of the
electronic delay to the thermal delay: The contactor
will now de-energize,and the remaining contactors
will follow in the normal off sequence. Replace the
defective thermal delay.
b. If the A.C. voltage is low, remove one secondary lead from its load
connection.
1) If the A.C. voltage returns to 24V, the transformer is good.
2) If the A.C. voltage remains low, check the primary voltage. It
should measure 240 or 480 volts A.C. accordingly ± 10%. If
the primary voltage is correct, replace the transformer.
5. If the transformer is good, follow the voltage path using the wiring
diagram. Check each control for voltage in and out. Replace where
voltage fails.
Symptom—Low heat
One or more contactors do not energize. Operation of any contactor, beyond
the first is dependent upon the operation of three components.
Symptom—Inoperative
circulator
1. Measure the voltage at the circulator terminals with
the boiler energized. If the voltage is 120V ± 10%,
the control is good. If no voltage is present, replace
the circulator relay (1K).
•

•
Thermal time delay.
Electronic time delay; 2½ minutes.
Contactor.
1. Observe the sequence of operation and note at which contactor it is
interrupted. If one contactor fails to energize because of an open coil,
subsequent contactors will be affected (unless one has a shorted coil).
To isolate the trouble, proceed as follows:
a. Check contactor. Connect a jumper from terminal 3 of the
electronic delay to the transformer wire going to terminal “B” on
the “low” side of the limit control.
b. If the contactor energizes check electronic and thermal delays.
Remove the jumper from the transformer terminal and touch it
to terminal 1 of the electronic delay. (The jumper now connects
terminals 1 and 3 of the electronic delay). If the contactor
energizes, replace the electronic time delay. If it fails to energize,
replace the thermal time delay.

Water treatment
Do not use petroleum-based cleaning or sealing compounds in boiler
system. Severe damage to boiler will result, causing substantial property
damage.
Eliminate all leaks. Continual fresh makeup water will reduce boiler life.
Minerals can build up in section, reducing heat transfer, overheating cast
iron, and causing section failure.
In hard water areas or low pH conditions (below 7.0), consult local water treatment company.
Boiler water pH of 7.0 to 8.5 is recommended.
Freeze protection (when used)
See WARNING on page 2 for important information regarding glycol hazard.
Do not use automotive, ethylene glycol or undiluted antifreeze. Severe
personal injury, death or substantial property damage can result.
Use antifreeze especially made for hydronic systems. Inhibited propylene glycol is
recommended.
50% solution provides protection to about -30°F.
Local codes may require a back-flow preventer or actual disconnect from city water supply.
Determine quantity according to system water content. Boiler water content is listed in the
Ratings table on page 13. Remember to add in expansion tank water content.
Filling the system with water
Never apply power to the boiler unless the boiler is filled with water.
1. Close manual air vents, drain cocks, and automatic air vent, if used.
2. Fill the boiler and system to an initial pressure of about 12 pounds per square inch.
3. Open automatic air vent one turn, if used.
