Precedence® Sliding Window Installation Instructions
For Horizontal Sliding Windows
READ THE QUICK GUIDE BELOW OR DOWNLOAD THE FULL INSTRUCTIONS HERE
STEP 1: Prepare the Opening
Note: Prior to removing the old window, cross check the height and width of the new unit for correct fit.
From the inside of the house:
- Remove the old sliding window sash by removing the interior blind stop or interior trim. Use a utiltity knife to break the paint bond between the trim and the frame. This will allow for a more attractive finish with less potential for touch up. See Details 1 & 2.
Remove the inner sash:
- Depending on the age of the unit being replaced, there may be a sash cord connected to a pulley system. Cut the sash cord to permit sash removal. See Detail 3.
Remove the outer sash:
- If a parting stop exists, remove with a pry bar and chisel and repeat the same procedure for the outer sash. (If installing from the outside of the house, remove the blind stop and use the procedure above starting with the inner sash.)
STEP 2: Replacing the Window
Note: Prior to installing the new Precedence window, check the opening for squareness by performing corner-to-corner diagonal measurements. If the opening is out of square, adjust the opening by making additional cut backs to the rough opening in the appropriate areas.
- Place the sill anchor plate on the wood sill. Shim to level if necessary and secure the sill anchor plate to the wood sill with #8 x 1-1/2” fasteners. See Detail 4.
- Place the window in the opening for a trial fit. For installations on top of sloped sills, measure directly from the bottom of the window to the sill directly below during the trial fit.
- Remove the window and cut the sill extender to this height and apply the window.
- If you are using a head expander, caulk the length of the back side, place in the head of
- the opening against the blind stops and secure the opening.
- Caulk the blind stops where the window will make contact at the head and jambs as shown in Detail 5.
- Rotate the replacement window into place and push firmly against the blind stops.
Note: All fasteners must be a minimum of #8, corrosion resistant flat head screws that must penetrate the subframe a minimum of 3/4.”
- Fasten a screw through one of the top corners. Shims are required at each fastener location (top, middle, and bottom of each jamb).
- Take diagonal measurements to assure the unit is square. Opening the movable sash approximately 1/2” will provide visual confirmation of the proper setting that the reveal between the frame and sash (A & B) are equal the entire width. See Detail 6.
- Once squareness has been achieved, install the remaining fasteners at the head and jambs into the substrate.
- Insert E3-5042 rubber bumpers at the anchor fastener holes in the jambs. See Detail 7.
STEP 3: Finishing
- Check operation of the unit and make adjustments if necessary. Insulate as needed.
- Replace interior trim or exterior blind stop if installed from the outside.
- Caulk the bottom of the sill extender to the sill and the perimeter of the unit where it meets the blind stop on the outside. See Detail 8.
- Do not use expanding or spray-in foam products. If the installer used one of them, make sure jambs remain straight to ensure the operation of the window is not impeded.
- If using brick or stone exteriors, leave a 1/8” gap from the window to allow for brick and mortar expansion. Use a backer rod and silicone caulk to seal the gap.
- Do not use brick wash after windows are installed. Doing so will void the window warranty.
- Windows should never be stored in an area where temperatures will exceed 140° F. Doing so will void the window warranty.
- Windows should never be painted. Doing so will void the window warranty.
