1. The figures below show a vent configuration for a SSG vent with a fixed horizontal at the vent sill. All other vent configurations will receive the WA07 preset
gasket in the same fashion. See Figures 197 - 200, page 77, 201 - 204, page 78, and 205 - 208, page 79.
2. Apply the interior WA07 preset gasket starting at the center of the head sash. The interior WA07 gasket wraps around on all four sides of the vent with one
continuous piece. Form as tight a radius as possible at the corners with the gasket. Ensure the gasket is not stretched during application. Butt the ends
together at the head, crowding in extra gasket to ovoid gaps later due to gasket shrinkage. See the Figures below and 194 - 196 on page 76.
3. Apply the exterior WA07 preset gasket to the jamb starting and ending 3” above the sill sash wrapping around the corners at the head. The exterior WA07
wraps around both jambs and the head on only three sides of the vent as one continuous piece. (See Figure 192).
4. Apply a piece of the WA07 preset gasket to the exterior leg of the sill sash of the vent that starts and stops 6” short of the jamb sash. See Figure 192 below.
