4. Read and apply the harness plug warning label (shown above)
so that it is visible after installation
5. 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 harness
is disconnected, the system safety shutdown will
occur. The boiler will not operate until harness is
reconnected.
Effikal damper — Damper hold open switch must be
in Automatic Operation position for system to operate
properly.

Vent damper assemblies
Vent damper
These systems are used on gas-fired boilers with
vent dampers as shipped from factory. Boiler will not
operate without vent damper installed.
Damper blade
See vent manufacturer’s instructions to install plug (shipped with
damper) in damper hole. Install plug with
3
/

" diameter hole in vent
damper hole.
Minimum clearances
Provide a minimum of 6" between the vent damper and any
combustible material. (See “Minimum clearance to combustible
materials,” page 3, for minimum clearance from jacket top to ceiling
to maintain this dimension.)
Damper installation
Do not modify draft diverter or vent damper, or make
another connection between draft diverter and vent
damper or boiler except as noted below. This will void
CSA certification and will not be covered by warranty.
Any changes will cause severe personal injury, death
or substantial property damage.
1. Install vent damper 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 4.
2. Screws or rivets used to secure the vent damper to the draft
diverter must not interfere with rotation of the damper blade.
3. Install damper harness between damper actuator and knockout
in jacket top panel. Use strain relief connectors and locknuts to
secure both ends of damper harness.
Keep wiring harness clear of all hot surfaces. Wire
insulation could be damaged, causing risk of electrical
short-circuit.
