MOUNTING
On vertical vents, the vent damper may be mounted with the actuator in any position. On horizontal vents,
do not mount the actuator either directly above or directly below the vent pipe; mount the vent damper actuator
to the side of the vent.
The vent damper is set up for a continuous pilot system. If the vent damper is installed on an Intermittent Pilot
or Hot Surface Ignition equipped system, the energy savings of the vent damper can be improved by plugging the
hole in the vent damper blade using the knockout plug, Part No. 105612R, provided in the parts envelope.

DO NOT plug the hole if installing the vent damper on a continuous pilot system as this will create a
hazardous condition.
