NOTE: Entire damper frame is not required to be installed within the wall. The damper blades, when closed should be contained within the wall.

		Externally mounted actuators always require space
		outside of the damper sleeve. The “S” dimension il-
		lustrates the clearance required for various available
		actuators.

On dampers less than 18 in. (457mm) high, actuators may also require clearances above and/or below the sleeve. “B” and “T” dimensions are worst case clear- ance requirements for some dampers less than 18 in. (457 mm) high. All damper sizes under 18 in. (457mm) high do not require these worst case clearances. If space availability above or below the damper sleeve is limited, each damper size should be individually evalu- ated.
