Series 433 Triple Set Installation Instructions
SECTION VI: Subsill Fabrication and Installation
(Includes Offset and Center-Set Glazing)
Step 5) Chalk Line for Subsill
Before installing the subsill, measure the distance from the exterior of the condition to
the desired location at the EXTERIOR of the subsill. (The exterior of the subsill will be
flush with the rest of the system.) Do this at both ends of the condition. Snap a chalk
line between the two marks to align the subsill. If the condition is too wide for just two
marks, measure every 15 feet and snap a chalk line.
Step 6) Sealant Bed
Apply sealant to the subsill as shown in Figures 9 and 10. Place the subsill into the
rough opening, and rotate the exterior face down into position. Apply enough sealant
to ensure a complete seal as shown in
Figure 11.
