PROPER PATIO DOOR INSTALLATION
LEVEL INDICATOR
Accurate measurements are essential in determining level and plumb.
Most carpenters' levels have several bubble level indicators, making it
possible to measure all parts of the window.
Examine the horizontal indicator. If the bubble is centered between the
lines of the indicator, it is level.
If the bubble is not exactly centered, measure how far “out of level” or
“out of plumb” by maneuvering the end of the level until the bubble is
exactly centered. Measure the farthest gap between the level and the
surface.Thegapmustnotexceed1/4",orthesurfaceisoutoflevel/

•Proper installation is essential for keeping patio doors operating smoothly. If a patio door fails to operate properly, an inspection is necessary to
determine if it was installed correctly.
•A contractor or installer can assist in determining the cause of a patio door being “out of specication” and possibly correct it. Patio door problems due
to improper installation are usually not covered by the manufacturer’s warranty. For installation instructions, contact us or your supplier.

Note: These instructions do not address inspection for proper “water tightness” or ashing. A “water tight” inspection requires removal of the exterior
siding around the patio door. Seek professional assistance regarding this issue.
