General Installation
The four intersections of the cross-tees and main runners at the corners
of the grid module containing the diffuser, or the midpoint of the cross-

tees adjacent to the diffuser, shall be directly supported from the structural members of the floor or roof by 12 SWG minimum vertical hanger
wires. When the duct extends over the intersections of the grid
members, minimum No. 16 gauge, cold-rolled steel channels shall be
used to ensure that the grid is supported from structural members by 12
SWG minimum hanger wires. All UL Classified ceiling assemblies
require lay-in ceiling panels be cut to fill the remainder of the 24” x 48”
module and shall provide a minimum of 3/8” bearing on the ceiling grid
members.
A steel clamp of No. 16 SWG minimum steel wire shall fasten the flex
air duct to the damper when flex air duct is used to connect the main
duct to the damper. The flex air duct shall be Class 0 or Class 1 and
bear the UL Listing Mark. Refer to the UL Fire Resistance Directory
“Design Information Section — General” for installation requirements.
IMPORTANT: Screws, bolts, rivets, etc. used in connection of the
damper MUST NOT INTERFERE WITH DAMPER BLADE
OPERATION. Hanger wires
must be vertical and not splayed.
The damper must be fastened to the diffuser neck or grille frame in
installations 1, 2, 3, 4, and 5. The damper must also be fastened to the
duct drop in installation 2.

APPLICATION
Fire Resistance Classified Ceiling Air Diffusers are for use in lieu of
hinged-blade sheet metal dampers in steel ducts as specified in the
“Design Information Section — General” and in individual floor/ceiling or
roof/ceiling designs used as illustrated and described in the UL Fire
3/4"
Resistance Directory (FRD). When installed as shown and as described
herein, these ceiling air diffusers provide appropriate protection to
ceiling penetrations in any fire rated floor/ceiling or roof/ceiling assemblies with ratings of three hours or less as described in the FRD.
A maximum size ceiling penetration of 576 square inches can be
protected using the thermal insulating blanket furnished with the ceiling
air diffuser. The thermal insulating blanket protects the exposed

portions of the ceiling diffuser and the ceiling damper protects the neck
or inlet of the ceiling diffuser.
All system components (ducts, duct drops, sleeves, diffuser pan, or
grille frames) must be constructed of steel. The installations and
diffusers shown in these instructions illustrate general arrangement
only. Installations must also incorporate any specific
requirements
included in the FRD. Note that both “Design Information Section —

An adjustable damper must be installed in closed position with clearance between the diffuser and adjustment mechanism. Cycle the damper open
after the diffuser and damper have been completely assembled and clearance verified.
