death or substantial property damage.
This system is used on gas-fired boilers without vent dampers as shipped from
the factory. This system is not offered for retrofit. Any attempt to apply the system
components to boilers shipped for use with a different control system will not
be covered under boiler warranty and can cause severe personal injury, death or
substantial property damage.
When calling or writing about the boiler, please have the boiler model number
from the boiler rating label and the CP number from the boiler jacket.

Damper installation
If not installing a vent damper, proceed to page 21.
Figure 9 Vent damper assemblies
Once damper is installed, boiler will not operate without a
damper installed.
Only dampers listed in the Replacement parts table on page 32 are approved for use on EG-30 through EG-75 Series 4 and
PEG-30 through PEG-65 Series 4 using Universal Control
Systems. Any other vent damper installed could cause severe
personal injury or death.
The following boiler models must have
damper installed:
• EG-30 through EG-65, natural or propane gas.
•
PEG-30 through PEG-65, steam, natural gas.
Figure 10 Vent damper harness plug warning label
The following boiler models may have damper
installed:
•
EG-75 and EGH-85 through EGH-125, natural or propane
gas.
Minimum clearances to combustibles
Provide a minimum of 6” between the vent damper and any combustible
material. (Provide a minimum of 46” between jacket top and combustible
ceiling for EG/PEG, or 24” for EGH.) See EG • PEG • EGH Boiler manual
for complete clearance requirements.
Installation
1.
2.
3.
4.
Damper must be installed directly on top of draft hood so
that it serves only that boiler. Do not modify draft hood or
damper, or make another connection between draft hood and
damper or boiler except as noted below. This will void CSA
certification and will not be covered by Weil-McLain warranty. Any changes will cause severe personal injury, death,
or substantial property damage.
Install plug (packed in damper carton of 4” through 8” dampers) in
hole in damper blade.
Install vent damper horizontally or vertically as shown in vent damper
manufacturer’s instructions. Vent damper must be installed so that it
serves only one boiler and so damper blade indicator is visible to the
user. See Figure 9.
Screws or rivets used to secure the vent damper to the draft hood must
not interfere with rotation of the damper blade.
Install damper harness between damper actuator and knockout in jacket
top panel. Use strain relief connectors and locknuts to secure both ends
of the damper harness.
Keep wiring harness clear of all hot surfaces.
20
5. Read and apply the harness plug warning label
(Figure 10) so that it is visible after installation.
6. Plug damper harness receptacle into damper harness
plug.
Bypassing (jumpering) vent damper will
cause flue products such as carbon monoxide to escape into the house. This will
cause severe personal injury or death.
After boiler has operated once, if either
end of the harness is disconnected, the
system safety shutdown will occur. The
boiler will not operate until harness is
reconnected.
Effikal or Field Controls damper — Damper hold open switch must be in “Automatic
Operation” position for system to operate
properly.

Checkout procedure
1. See pages 22–26 for “Operating instructions.”
2. Raise room thermostat to call for heat. Damper actuator will slowly open damper.
3. When damper is fully open, main gas valve will open and main burners will ignite.
Damper must be fully open before main burners light. If damper does not fully
open, flue products will escape into house, causing severe personal injury or
death.
4. Lower thermostat setting. Main burner flames will go out, then damper will close.
5. Repeat steps 1 through 3 several times to verify operation.
6. Return thermostat to normal setting.

Troubleshooting
Burner access panel must be in position during boiler operation to prevent
momentary flame rollout on ignition of
main flame. Severe personal injury or
substantial property damage will result.
Never jumper (bypass) any device except for momentary testing as outlined
in Troubleshooting Charts. Substantial
property damage and/or severe personal
injury could occur.
Label all wires prior to disconnection
when servicing controls. Wiring errors
can cause improper and dangerous operation.
Verify proper operation after servicing. See
vent damper manufacturer’s instructions
packed with vent damper for additional
information. Failure to comply could
result in severe personal injury, death or
substantial property damage.
Before troubleshooting
1. Have a voltmeter that can check 120 VAC, 24 VAC,
and a continuity tester.
2. Check for 120 VAC (minimum 102 to maximum
132) to boiler.
3. Make sure thermostat is calling for heat and contacts
(including appropriate zone controls) are closed.
Check for 24VAC between thermostat wire nuts and
ground.
In event of vent damper failure:
Effikal or Field Controls vent damper
If troubleshooting chart recommends replacing actuator and actuator is
not immediately available, damper blade can be fixed in an open position
to allow boiler operation. Manually turning blade can cause actuator
damage. Follow these instructions only in case of no heat or damper
actuator malfunction.
1. Move damper service switch to Hold Damper Open position. Apply call
for heat to boiler. Damper blade should then rotate to open position
and boiler will fire.
2. If step 1 does not open damper, manually rotate damper blade to open
position using wrench or pliers on flat shaft between damper and actuator. Boiler will fire. Verify that damper service switch is in Hold Damper
Open position (Figure 11).
3. Do not leave vent damper permanently in this position. Replace actuator immediately. If vent damper is left in open position, boiler will not
operate at published efficiencies.
Johnson Controls vent damper
If troubleshooting chart recommends replacing actuator and actuator is
not immediately available, damper blade can be fixed in an open position
to allow boiler operation. Follow these instructions only in case of no heat
or damper actuator malfunction. See Figure 11.
1. Turn off power to boiler.
2.
3.
4.
5.
Failure to turn off power to boiler can result in severe personal
injury, death or substantial property damage.
Refer to vent damper manufacturer’s instructions for procedure to fix
vent damper in open position.
Turn on power to boiler.
Using wrench or pliers on flat shaft section, manually rotate damper
blade until green light turns on. Boiler will fire (Figure 11).
Do not leave vent damper permanently in this position. Replace
actuator immediately. If vent damper is left in open position, boiler will
not operate at published efficiencies.

CHART 3 (continued): Procedure to check system grounding
Pilot assembly and ignition control must share common ground
with main burner. Nuisance shutdowns are often caused by
poor or erratic ground.
• Check for good metal-to-metal contact between pilot burner
bracket and main burner, and between main burner and
burner rest.
• Check ground lead from “GND (Burner)” terminal on ignition
control to ignition control mounting screw, and from “C”
on transformer to transformer case ground. Make sure
connections are clean and tight. If wire is damaged or
deteriorated, replace with No. 18 gauge moisture-resistant,
thermoplastic-insulated wire with 105°C minimum rating.

Open manual hand valve.
Contact gas supplier to correct gas pressure.
Is gas present at pilot burner assembly?
To check for gas at pilot —
Remove the wire to “MV”

taped to a long screwdriver or pilot
lighter rod to manually light the pilot.
Does the pilot light?
No
Yes
Make sure gas cock is in “ON” position and
pilot line is not kinked or obstructed. Check
for clean pilot orifice. If OK, replace the gas
