b.         Verify block-out dimensions and structural support for flush recessed surrounding frame.

c.         Verify the structural integrity of the header for deflection with live and dead loads limited to the lesser of L/720 of the span or 1/4 inch (6 mm). Provide structural support for lateral loads, and both wind load and eccentric load when the panels are stacked open.

NOTE:  Structural support for lateral loads such as forced entry, etc. to be provided.                            

            It's recommended that all building dead loads be applied to the header prior to installing the unit. 

            If so, and if a reasonable amount of time has been allowed for the effect of this dead load on the header, only then can the building live load be used to meet the above requirements of L/720 of the span or 1/4 inch (6 mm), whichever is less.

            If not, both dead and live loads need to be considered.
