Turn the two position-fixing screws 1/2 turn counterclockwise on each hinge. Doing so will allow you to make the necessary adjustments. The screws have hex heads, and so it's necessary to use the hex wrench that came with the door.
Twist the horizontal adjustment screw to adjust the horizontal gap between the door panel and the frame. Turning the screw counterclockwise increases the gap while turning it clockwise decreases the gap. Make adjustments until the door closes with ease. When you are satisfied with the horizontal adjustment, tighten the two position-fixing screws on the hinge.
Twist the screw at the bottom of each hinge to alter the door's vertical adjustment. Twisting the screw clockwise moves the door up, and twisting counterclockwise moves it down. Start at the bottom hinge, and then work your way upward, adjusting the bottom screw of the other hinges until the door closes with ease.
Check the hinges for the horizontal adjustment screw. The horizontal adjustment screw is marked with "IN" and "OUT" and an arrow pointing in each direction. Note that modern Andersen door hinges have no position-fixing screws.
Twist the screw toward the "IN" marking to move the door closer to the frame. Twist the screw toward the "OUT" marking to move it away from the frame. Make the necessary adjustments on all of the hinges.
Examine the vertical adjustment screw at the bottom of each hinge. Note the plus (+) and minus (-) signs on the screw. Twisting toward the plus sign moves the door up, and twisting toward the minus sign moves it down.
Twist the vertical adjustment screw on each hinge in the appropriate direction until the door closes easily. Start with the bottom hinge, and work your way upward to the other hinges.
