You must first have the proper size of glass, typically 1'' larger both ways than your day light opening. You should already have your seting blocks in place on the sill. This is usually at least a 2 man operation, for after you place your glass in the opening, it must physically be held in place until temporary mechanical stops are put in place. (Short cut offs of the pressure bar screwed into the screw race of the mullion)

After you have all glass in for that "run", you start putting on the full length pieces of vertical pressure bar. Start at the top, as you work down remove the temporary stops. After the vertical pressure bar is on, go back and put on the horizontal pressure bars. (Don't forget the weep holes and "marrying" of the corners of the vinyl - IMPORTANT STEP!

Depending on the lay out of the elevation you are working on, you may want to complete all of the pressure bar before putting on the face cap (Be sure and use a flat block on the cap when pounding it on, if you don't you get many, many dents)
