2. SLEEVE LENGTH AND WALL THICKNESS
Insert the sleeved damper assembly into the prepared
opening, to appropriate depth (refer to label on outside
of sleeve for location of damper in wall; see Page 3,
Dimension A and Detail 1, Fig. 1).
Recommended maximum and minimum insertion depth
can be exceeded if:
1) The operation of the damper is not impeded
and
2) The
C
L
of the damper frame remains within the
plane of the wall and
3) Attachments made through the retaining
angle do not penetrate the ‘No Screw’ area
designated on the damper sleeve.
IMPORTANT SAFETY DANGER! : To avoid
causing death or serious bodily harm to
building occupants, do not penetrate the ‘No
Screw’ area designated on the damper sleeve
or the damper may not close properly.
The sleeve may extend a maximum of 16 in. beyond the
wall or floor on the actuator side of the damper and a
maximum of 6 in. on the opposite side. Recommended
standard sleeve lengths for various wall thicknesses are:
Wall Thickness Sleeve Length
Dimension
(T
W
) Dimension (L)
4-6 in. 16 in.
7-10 in. 21 in.
11-13 in. 24 in.
3. DUCT TO SLEEVE CONNECTIONS
Dampers are supplied with sleeves and actuators from
the factory and can be installed without the need for
additional field installed sleeves.
Gauge of factory furnished sleeve determines the
type of duct to sleeve connections required (see table
below). Any duct connection other than the breakaway
connections described on page 7 are considered rigid.
Factory furnished duct collars, type R and O, are also
considered breakaway (see Fig. 2).
Type of Duct to
Sleeve Gauge Duct Dimension Sleeve Connection
Permitted
14 ga. (0.075 in.)-
All duct sizes Rigid or Breakaway
10 ga. (0.138 in.)
36 in. max. width
16 ga. (0.060 in.) 24 in. max. height Rigid only
24 in. max. dia.
16 ga. (0.060 in.) All duct sizes Breakaway only
84 in. max. width
20 ga. (0.036 in.) Breakaway only
55 in. max. dia.
See page 7 for additional information on breakaway sleeve
connections.
Sleeve thickness must not be less than the gauge of the connecting
duct.
UL Standard 555 requires all ducts to terminate at fire damper
sleeves.

4. SECURING THE DAMPER/SLEEVE ASSEMBLY
TO WALL AND FLOOR OPENINGS (for
single side retaining angle instructions, see
supplements)
Damper/sleeve assemblies must be installed in wall and
floor openings using retaining angles on at least one side
of the wall or floor as described below:
• Retaining angles must be a minimum of 16 gauge
steel and have a minimum of 1
1
/2 in. x 1
1
/2 in. legs.
• Retaining angles must be attached to the damper
using one or more of the following methods of
attachment (refer to label on outside of sleeve for ‘No
Screw’ area):
•Tack or spot welds
• #10 (
3
/4 in. max.) sheet metal screws
•
1
/4 in. bolts and nuts
•
3
/16 in. steel pop rivets
