APPLICATION

(D)0120GOW are “out of the wall” or floor integral sleeve curtain type fire dampers, specifically designed for supply or return ducts that terminate at a grille or register where the maximum free area is required.
The (D)0120GOW design provides sufficient damper offset to accommodate most commercial grille/register designs while ensuring an approved installation in any fire partition or wall no matter how narrow. This model is particularly suited for use in common steel stud drywall partition designs, as narrow as 3 1/2″ (89) where a traditional “within the plane of the wall” fire damper installation is not possible.

NOTES:
IMPORTANT: DAMPER IS FURNISHED FULL-SIZE (See Note 3)

Installation shall be under the appropriate requirements of the National Fire Protection Association Standard NFPA 90A latest edition.
Damper Sleeve: These dampers are supplied with a factory-furnished sleeve which shall not be less than 16 gauge (1.16) coated steel.
Sleeve thickness must be equal to or thicker than the duct connected to it. Sleeves may be attached to the duct with cleats, screws or other types of mechanical fasteners. The maximum sleeve thickness for such rigid joints is 10 gauge (3.51) for coated steel.
Expansion Clearance and Opening Preparation. To accommodate the damper sleeve thickness and insulation, frame and finish the opening so that it is 1/2″ (13) larger in width and height than the duct size. Dampers are furnished with an inside sleeve dimension full ordered size to facilitate grille installation.
Flange / Retaining Angle and Fasteners. For installation in a masonry wall or floor/ceiling and metal stud drywall partitions, no rear retaining angles are required. Insert the damper/sleeve combination into the opening so that the damper sleeve is flush with the wall/grille opening. Attach a full-length 3/4″ x 3/4″ x 16 ga. (19 x 19 x 1.61) flange on the grille side of the sleeve on all four sides (field supplied). Secure the flanges to the sleeve with 1/2″ (12.7) long welds, 1/4″ (6.35) dia. bolts and nuts, 3/16″ (4.76) dia. steel rivets or #8 sheet metal screws 8″ (203) on centre and 2″ (51) maximum from the corner of the sleeve on all four sides. Secure the damper in the wall opening from inside the sleeve as shown above by use of the following:
- a. In metal stud/drywall walls, partitions and cavity shaft wall partitions, use minimum #10 sheet metal screws.
- b. In masonry walls or floor/ceilings use minimum #10 self-tapping concrete wall anchors. Anchors must penetrate the wall or floor a minimum of 1 1/2″ (38).
- c. In wood stud, use minimum #10 steel screws, 2 1/2″ (64) long with minimum 1 1/2″ (38) penetration into the framing.
  Maximum distance of damper outside of the barrier shall be 1″ (25).
  Fasteners shall be spaced a maximum of 6″ (152) on centre and 2″ (51) maximum from corners, a minimum of two per side is required.
  Alternatively, 1 1/2″ x 1 1/2″ x 16 gauge (38 x 38 x 1.61) rear retaining angles may be used instead of the above-prescribed method and secured to the sleeve with 1/2″ (12.7) long welds, 1/4″ (6.35) dia. bolts and nuts, 3/16″ (4.76) dia. steel rivets or #8 sheet metal screws, 8″ (203) on centre and 2″ (51) maximum from the corner of the sleeve on all four sides.
