How do you level and plumb a sliding glass door?

The question is a little confusing. If the floor is level you just put the bottom of the sliding glass door track on the floor. With the stationary section of glass in place the one side of the door should now be quite plumb and all you have to do is attach that part of the frame to the house. On the other hand, if you are asking about a door that is already installed and are wanting to plumb the slider, there should be two screws near the bottom of the door sides and two screws near the top. In order to turn the bottom screws it may be necessary to relieve pressure from the top screws and slightly lift the bottom of the door. Adjust the door so that it is parallel to either the stationary glass or the side frame, whichever side has the locking mechanism. LEVEL equalls left to right.....so place door in a bed of silicone greater than the amount the existing floor is out and shim the appropriate side up until the top of door from left to right is level PLUMB is vertical....... top to bottom and left to right with in one side of the jamb;;;jamb must be plumb in both direction and on both sides of jamb within a straight lin of itself for it to be SQUARE....
