Notes

1. Gypsum panels must be screwed 12 in. (305mm) on center

maximum to all stud and runner flanges surrounding opening. (See Figure 1 and Figure 2 for Opening Preparation Details).

2. Fire damper and sleeve assemblies 80 in. W x 50 in. H (2032mm x 1270mm), 50 in. W x 80 in. H (1270mm x 2032mm), or 40 in. W x 100 in. H (1016mm x 2540mm) and smaller only require retaining angles on one side of the partition (See Figure 3 and Figure 4). Retaining angles must be attached to the sleeve and the partition. Larger damper assemblies require retaining angles on both sides of the partition. Retaining angles must be attached to the sleeve.

• Retaining angles for 1½ hour rated dampers with a width

and height 48 in. (1219mm) or less must be a minimum of 20 ga. (1mm). Retaining angles for all 3 hour rated dampers and all dampers with a width or height greater than 48 in. (1219mm) must be a minimum of 16 gauge (1.5mm). The leg of the retaining angle on the damper sleeve shall be a minimum of 1¼ in. (32mm). The leg of the retaining angle on the wall/floor shall be long enough to cover the annular space and overlap the wall/floor by at least 1 in. (25mm).

• Retaining angles must be attached to the partition and

sleeve using one of the methods shown below.

• tack or spot welds

• #10 sheet metal screws and bolts

• Drywall screws of a length such that the screw

engages the stud/track by a minimum of 1/2 in. (13mm)

• A minimum of two connections per side, top, and

bottom, 12 in. on center maximum for openings of 48 in. W x 36 in. H (1219mm x 914mm) and less, and 6 in. (152mm) on center for openings 80 in. W x 50 in. H (2032mm x 1270mm), 50 in. W x 80 in. H (1270mm x 2032mm), and 40 in. W x 100 in. H (1016mm x 2540mm) or less.

• Angle legs may be reversed and one leg inserted into the wall opening. Retaining angles used in conjunction with grille installations must be a minimum of 20 gauge (1mm) steel and have a minimum of 5/8 x 1 in. (16mm x 25mm) legs (See Figure 5 and Figure 6).

• Using #10 sheet metal screws, screw from inside of

sleeve into the studs. Space screws a maximum of 6 in. (152mm) on center and a maximum of 2 in. (51mm) from the corners (minimum of 2 screws per side). (See Figure

7 and Figure 8).
