Damper installation

If not installing a vent damper, proceed to page 21.
Once damper is installed, boiler will not operate without a
damper installed.
Only dampers listed in the Replacement parts table on
page 42 are approved for use on EG-30 through EG-75
Series 6 and PEG-30 through PEG-65 Series 6, using Uni-
versal 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 gas.
• PEG-30 through PEG-65, steam, natural gas.
The following boiler models may have
damper installed:
• EG-75, natural gas.
• EGH-85 through EGH-125, natural or liquefied
petroleum (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 and 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
warranty. Any changes will cause severe personal injury,
death, or substantial property damage.
1. Install plug (packed in damper carton of 4" through 8" dampers) in
hole in damper blade.
2. 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 8.
3. Screws or rivets used to secure the vent damper to the draft hood
must not interfere with rotation of the damper blade.
4. 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.

5. Read and apply the harness plug warning label
(Figure 9) 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 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.
Damper setting
switch must be in "Automatic Operation"
position for system to operate properly.
