1 >> The damper should be installed centrally within surrounding masonry floor or wall

2>> The damper should be installed in a rectangular galvanized steel sleeve with a min. thickness of 1.2 mm This sleeve

should be attached to the damper not to the builder’s work using the mounting channels by 6mm dia bolts spaced at not

more than 255mm centres. Bolts for mounting channels located maximum 45 and 145 mm from corners of sleeve and frame,

perspectively.

3>> The damper is suitable only for rectangular space and can not be used for annular space.

4>> Allowance for expansion between sleeve and builder’s work in both horizontal and vertical planes to be 3mm per 305mm

of length.

5>> The sleeve should be of suitable length to extend through the wall to enable the fitting of the cover angles and

ductwork. Minimum of 90mm and maximum of 152mm beyond the floor or wall.

6>> The cover angles should be attached to the sleeve by 6mm dia bolts at a minimum of 225mm centres, and should

form a complete frame around the sleeve and cover over the expansion gap required between sleeve and wall opening. The

four corner of the cover angles are not to be welded.

The bolts connecting the cover angles to the sleeve to be 102mm maximum from the corners.

7>> The expansion gap should be filled with compressible, non-combustible material (mineral wool).

8>> The cover angle should be of such a size as always to from a cover over the wall opening by 25mm minimum and should

be manufactured from a minimum size of 38*38*3mm steel angle

9>> A fusible link UL tested Elsie brand which is rated at 165 degree F is used.

10>> The duct-sleeve connection to be of double “S” slip type.

Breakaway joints shown shall have no more than two No. 10 (4.8 mm dia.) sheet metal screws on each side and on the

bottom located in the center of the slip pocket and shall penetrate both sides of the slip pocket.

Breakaway joints for horizontal ducts (vertical fire damper) shall be provided on the top, bottom and on the sides with double

“S” slip type as illustrated.

Breakaway joints for vertical ducts (horizontal fire damper) shall be provided on both other opposite sides with double “S”

slip type.

Connecting ducts shall not be continued and shall terminate at the sleeve. Installation shall comply with NFPA 9OA.

11>> All fixing of frames must be positioned clear of damper blade path so as not to impede proper closure.

EXPLODED ASSEMBLY FOR FDC TYPE WITH SLEEVE

ASSEMBLY PROCEDURES:

1. Fix the damper into the sleeve matching their center axis and hole provision using steel rivet

2. If the riser angle (optional) is use then, fix the riser angle (optional) into the fire damper sleeve

matching their hole provision using steel rivet. If not go to step no. 3.

3. Fix the fire damper with sleeve into the concrete / gypsum wall opening by a front mounting angle

35x35 matching their hole provision using M8 Hex bolt and nut. Opening size should have clearance of 3 mm

per 305 mm of length and width.

4. Finally when the Fire Damper with sleeve is already fitted to the wall, fix the back mounting angle 35 x 35 matching

their hole provision using M8 Hex bolt and nut.
