Apply sealant on top

gasket and raceway.
Create a bed of
sealant to lay the
gutter splice into.

1. Once the two units are installed, a splice is required at the gutter at the top of the units. Clean the gutter sill sealant contact surfaces using an approved
solvent or cleaner of all oils and other contaminants where the gutter splice will be applied. The sealant manufacturer’s preparation and
application instructions should be followed exactly. If sealant primer is required, apply it per the primer/sealant manufacturer’s instructions.
2. Apply a bed of sealant on the gutter that will cover the area where the gutter splice (HC08 or HC09) will be applied. When creating the bed of sealant, apply
a generous amount of sealant directly on top of the primary seal location as shown in Figure 121.
3. The sealant must go from the front of the gutter up the engagement leg to the WC19 gasket track. See Figure 123 of the following page. The sealant bed
must be wide enough to cover the entire area of the gutter splice (HC08 or HC09). See Figure 122.
