& INSTALLATION

(CONT.)
After the subsill has been installed and anchored, it must be sealed
to the condition at each end with 795 or equivalent silicone type
sealant. If the subsill has an end dam, there should be a continuous
bead of 795 placed up both the interior and exterior and across the
top edges of the end dam where it meets the condition. The sealant
should be tooled to make a watertight seal between the end dam
and the condition.
If the subsill does not have an end dam, a continuous bead of
silicone type sealant must be applied to the end of the subsill where
it meets the condition. The sealant should be tooled to make a
watertight seal between the subsill and the condition.
See figures 28 and 29 below for sealant application.
