If a <br />door fails to operate properly, an inspection is necessary to determine if <br />it was installed correctly. <br />• A contractor or installer can assist in determining the cause of a door <br />being “out of specification” and possibly correct it. Door problems due <br />to improper installation are usually not covered by the manufacturer’s <br />warranty. For installation instructions, contact us or your supplier. <br />• The specifications and measurements referenced in this guide are <br />taken from ASTM E2112 Standard Practice for Installation of Exterior <br />Windows, Doors and Skylights. <br />NOTE: These instructions do not address inspection for proper <br />“water tightness” or flashing where the product integrates with <br />the structure. A “water tight” inspection requires removal of the <br />exterior siding and interior trim around the door. Seek professional <br />assistance regarding this issue. <br />Level Indicator <br />Accurate measurements are essential in determining level and plumb. <br />Most carpenters' levels have several bubble level indicators, making it <br />possible to measure all parts of the door. <br />Examine the horizontal indicator. If the bubble is centered between the <br />lines of the indicator, it is level. <br />If the bubble is not exactly centered, measure how far “out of level” or <br />“out of plumb” by maneuvering the end of the level until the bubble is <br />exactly centered. Measure the farthest gap between the level and the <br />surface. On a 4' level (or longer), the gap must not exceed 1/4", or the <br />surface is out of level/plumb. <br />Frame Twists <br />Attach two pieces of string to <br />frame, corner to corner. If there is <br />a gap between strings at center <br />point larger than 1/8", the frame is <br />not flat. Repeat by switching strings <br />and re-measuring. <br />Proper Shimming <br />Measure width of frame at top, <br />center, and bottom. If any two <br />measurements differ more than <br />1/16", the frame is over or under <br />shimmed. Repeat process and <br />measure height of frame. <br />Level and Plumb <br />For plumb, place level against each <br />side jamb or use a plumb bob. For <br />level, place level against head jamb <br />and sill. <br />Square <br />Measure frame from top left to <br />bottom right corner and from <br />top right to bottom left corner. If <br />measurements differ by 1/8", unit is <br />out-of-square.
