1. A glass lite retention system comprising:
a fenestration panel comprising an opening formed through the fenestration panel, the opening extending through the fenestration panel from a first major side of the fenestration panel to a second major side of the fenestration panel, the opening comprising an opening perimeter defining a shape of the opening;
a glass lite positioned in the opening;
a first frame positioned on the first major side of the fenestration panel, the first frame comprising one or more first frame members defining a shape of the first frame, wherein the first frame is positioned over a junction between a lite perimeter of the glass lite and the opening perimeter on the first major side of the fenestration panel; and
a second frame positioned on the second major side of the fenestration panel, the second frame comprising one or more second frame members defining a shape of the second frame, wherein the second frame is positioned over the junction between the lite perimeter and the opening perimeter on the second major side of the fenestration panel;
wherein a first frame-panel junction between the first frame and the first major side of the fenestration panel comprises an airtight panel seal between the first frame and the first major side of the fenestration panel;
wherein a first frame-lite junction between the first frame and a first major surface of the glass lite comprises an airtight lite seal between the first frame and the first major surface of the glass lite; and
wherein a second frame-panel junction between the second frame and the second major side of the fenestration panel comprises a vent between the second frame and the second major side of the fenestration panel at a selected location along the second frame-panel junction, and wherein the vent is configured to pass liquid water through the second frame-panel junction.
