Installation Instructions for an Andersen Patio Door

Lay the Andersen patio door frame on a flat work surface. The ends of each piece are contoured to fit tightly against each other to form a rectangle. Apply a generous bead of the supplied silicone caulk to the side pieces' top and bottom edges.

Press the pieces' ends together tightly. Insert a supplied screw through each of the screw holes and tighten them with a Phillips screwdriver to hold the frame together.

Measure the rough opening's width and add 12 inches. Transfer this measurement onto a piece of foil tape with rubber adhesive backing and cut the tape with a scissors. Center the tape over the opening's sill, with the ends extending 6 inches up either side. Press it into place. Cut the corners with a scissors and fold it down. Repeat this step around the entire opening.

Place a tube of silicone caulk in a caulk gun and cut off the tip. Run two beads of caulk along the rough opening's sill. Center the frame's sill in the rough opening, and tilt the frame up and into place.

Hammer a roofing nail through the frame's upper left fin to hold the frame in place. Lay a level on the frame's sill and against both sides. Insert wood shims between the frame and the rough opening, 6 to 8 inches from the top and bottom corners, to hold the frame plumb.

Drive 2-inch screws through the frame and wood shims and into the rough opening on the frame's latch side. Finish hammering roofing nails through the fin, placing one nail every 4 to 6 inches.

Fill the sill's screw holes with a bit of silicone caulk before you drive 2-inch screws through them. Drive screws around the rest of the door frame, placing them approximately 8 inches apart.

Cover the frame's nailing fin with foil tape. Lift the Andersen patio door's fixed panel into the frame's inner track, top edge first. Slide it all the way over. Place a supplied L-shaped metal clip against the panel in both the top and bottom track. Drive the three supplied screws through each clip to hold the panel in place.

Lift the Andersen patio door's sliding panel into the outer track. Go inside and slide the panel closed. Insert a small flathead screwdriver into the hole along the panel's bottom edge. Turn the screwdriver either clockwise or counterclockwise to adjust the panel's rollers either up or down. The panel should slide easily back and forth along the track.

Slide the sliding panel open. Insert the latch into the hole in the panel's edge. Secure it in place with the provided screws. Place one handle against the panel's outer side and the other handle against the panel's inner side, and press them together over the latch. Use the supplied screws to hold the handle together.
