1. Install the radiation damper onto the inlet side of the fan so that the holes in the sleeve align

with mounting holes on the fan using the four #10-32 x ½” long screws and 10-32 nuts

provided with the damper assembly (general installation). The mounting flange of the fan

should be aligned with the mounting flange of the damper assembly (refer to Figure 1).

2. Prior to the gypsum ceiling being placed, install the Damper Supports 13-3/16” on center at

the location of the damper and fan assembly. The supports consist of two pieces of 2x4’s;

one piece is to be cut to the truss/joist height (Damper support1), the second is to be cut per

the following equation (Damper Support 2). The supports are to be flush mounted to the

bottom of the joist/truss and secured using at minimum 2” wood screws. Sizes for the fan

supports are based on the presence of a resilient channel, please refer to the appropriate UL

floor/ceiling design. For reference:

3. Damper Support 2 is optional. An alternate Installation can be done using only Damper

Supports 1.

For a damper used with a fan equipped with a grille light, route the wire from the grille through the notch on the damper frame. Use the supplied bracket to secure the wire to the damper frame. Attach the bracket to the frame as seen in FIG. 3 using one of the supplied #8-18 screws. 5. If fan is not equipped with a lighted grille this bracket is to be installed as seen in FIG.2.
