1. NO ADDITIONAL SLEEVES ARE REQUIRED

field installed sleeve. Damper frame shall extend a maximum
of 6" beyond the wall or floor opening on each side.
2. CLEARANCES REQUIRED BETWEEN FIRE DAMPER
SLEEVES AND WALL/FLOOR OPENINGS
Fire damper assemblies expand during periods of intense
heat. Therefore, it is essential that openings in walls or floors
be larger than the fire damper assembly to allow for this
expansion. Minimum clearances required between the
outside of fire damper sleeve assemblies and wall/floor
openings are:
- Galvanized steel fire dampers and sleeves:
damper width and height with a minimum clearance of
Recommended clearances, for width and/or height
dimensions of:
1) 48" or less: 1 ⁄
2
2) More than 48" and 96" or less: 1" clearance
3) More than 96": 1
These are total clearances (ignoring fastener heads) and do
not need to be equally spaced around the damper. Refer to
