Issued in response to reports that contractors were receiving conflicting information on fire damper and combination smoke-fire damper installations, the update specifically addresses requirements to seal the retaining angles to the wall or floor fire-rated assembly and fill the expansion space with materials such as ceramic fiber or firestopping caulks.
