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 dam
