Face & Bypass
When the height of a face & bypass vertical style (FBV) is greater than 84 in. (2134mm), the damper sections are
shipped separate, requiring field assembly. Before fastening damper sections together, the non-actuated damper
section will need to be flipped upside down so that the linkage is on the same side as the actuated damper.
After damper sections are fastened together, attach
interconnecting angle as shown in Figure 4.
