. Read and apply the harness plug warning label
(Figure 10) so that it is visible after installation.
. Plug damper harness receptacle into damper harness
plug.
Bypassing (jumpering) vent damper will
cause flue products such as carbon mon-
oxide 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 — Damp-
er hold open switch must be in “Automatic
Operation” position for system to operate
properly.
Damper installation
If not installing a vent damper, proceed to page 1.
Once damper is installed, boiler will not operate without a
damper installed.
Only dampers listed in the Replacement parts table on page
are approved for use on EG-0 through EG- Series and
PEG-0 through PEG- Series 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.
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 ” between the vent damper and any combustible
material. (Provide a minimum of ” between jacket top and combustible
ceiling for EG/PEG, or ” for EGH.) See EG • PEG • EGH Boiler manual
for complete clearance requirements.
Installation
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 war-
ranty. Any changes will cause severe personal injury, death,
or substantial property damage.
1. Install plug (packed in damper carton of ” 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 .
. 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.
