Removal of old windows may disturb this paint. Proper precautions must be taken to minimize exposure to dust and debris. Consult state or local authorities and/or go to www.epa.gov/lead for more information. !!WARNING: To ensure safety and security and help prevent property damage, including possible damage to your window or door, close and lock windows and doors any time they are not being used for venting on a nice day, and particularly during high winds or rain. Important Notice Because all construction must anticipate some water infiltration, it is important that the wall system be designed and constructed to properly manage moisture. Pella Corporation is not responsible for claims or damages caused by anticipated and unanticipated water infiltration; deficiencies in building design, construction and maintenance; failure to install Pella products in accordance with Pella’s installation instructions; or the use of Pella products in wall systems which do not allow for proper management of moisture within the wall systems. The determination of the suitability of all building components, including the use of Pella products, as well as the design and installation of flashing and sealing systems are the responsibility of the Buyer or User, the architect, contractor, installer, or other construction professional and are not the responsibility of Pella. Pella products should not be used in barrier wall systems which do not allow for proper management of moisture within the wall systems, such as barrier Exterior Insulation and Finish Systems (EIFS) (also known as synthetic stucco) or other non-water managed systems. Except in the states of California, New Mexico, Arizona, Nevada, Utah and Colorado, Pella makes no warranty of any kind on and assumes no responsibility for Pella windows and doors installed in barrier wall systems. In the states listed above, the installation of Pella Products in barrier wall or similar systems must be in accordance with Pella’s installation instructions. Product modifications that are not approved by Pella Corporation will void the warranty. Care and Maintenance Care and maintenance information is available by contacting your local Pella retailer. This information is also available at www.pella.com. Cleaning Instructions GLASS: Remove any protective film and labels and clean the glass, using a soft, clean, grit-free cloth and mild soap or detergent. Be sure to remove all liquid by wiping dry or use a clean squeegee. FACTORY FINISHED PRODUCT: Pella product that has been prefinished with stain or paint from the factory requires no additional finishing. Clean the surface with mild soap and water. PELLA® ALUMINUM CLAD OR IMPERVIA FRAMES: The interior and exterior frame and sash are protected with a tough factory finish. Clean this surface with mild soap and water. Stubborn stains and deposits may be removed with mineral spirits. DO NOT use abrasives. DO NOT scrape or use tools that might damage the surface. ENCOMPASS BY PELLA®/THERMASTAR BY PELLA®, PELLA® 350 SERIES AND PELLA® 250 SERIES WINDOWS FRAMES: The vinyl frame may be cleaned using the same method as the glass. For stubborn dirt, a “non-abrasive" cleaner such as Bon-Ami® or Soft Scrub® may be used. Do not use solvents such as mineral spirits, toluene, xylene, naphtha or muriatic acid as they can dull the finish, soften the vinyl and/or cause failure of the insulated unit seal. Keep door tracks clear of dirt and debris. Keep weep holes open and clear of obstructions. DO NOT use abrasives. DO NOT scrape or use tools that might damage the surface. Notice: DO NOT use inappropriate solvents or brickwash or cleaning chemicals. If you do, permanent damage can result and the product failure, loss or damage would not be covered by the Limited Warranty.

Remove any construction residue before finishing. Sand all wood surfaces lightly with 180 grit or finer sandpaper. DO NOT use steel wool. BE CAREFUL NOT TO SCRATCH THE GLASS. Remove sanding dust. Pella products must be finished per the below instructions; failure to follow these instructions voids the Limited Warranty. Note: To maintain proper product performance do not paint, finish or remove the weatherstripping, mohair dust pads, gaskets or vinyl parts. Air and water leakage will result if these parts are removed. After finishing, allow venting windows and doors to dry completely before closing them. If paint, stain or finish gets on the weatherstripping, wipe it off immediately with a damp cloth. Window Cleaning and Prep Instructions for Unfinished or Primed windows: Dry wipe dust from windows gently. Examine window for possible smudges or fingerprints made from normal handling or construction. To remove smudges, lightly wipe surface with warm water. Scuff sand with light grade sand paper or abrasive pad (220 grit or higher). Rinse surface with warm water. Let window surfaces dry completely before applying finish. Finish the windows as soon as possible after installation. • On casement and awnings, it is optional to paint, stain or finish the vertical and horizontal sash edges. • On single-hungs and double-hungs, do not paint, stain or finish the vertical sash edges, any finish on the vertical sash edges may cause the sash to stick; it is optional to paint, stain or finish the horizontal sash edges. Pella Corporation is not responsible for interior paint and stain finish imperfections for any product that is not factory-applied by Pella Corporation. For additional information on finishing see the Pella Owner’s Manual or go to www.pella.com.

Remove the vent sash and screen from the old window. B. Remove the fixed sash. In some cases, there are screws holding in the fixed sash. Remove the screws and take out the fixed sash. NOTE: There may be a need to break the caulking free from around the fixed sash before it can be removed. C. Remove the division bar by unscrewing the fasteners holding it to the frame. If the screws are not accessible, then use a hacksaw to cut the division bar off at the head and sill flush with the old window frame. This method of Full Frame Removal involves removing the sash and entire frame of the existing window from the wall. The resulting opening is the original rough opening. The existing window nailing fins are usually nailed to the studs in frame construction with siding, brick veneer or other exterior material applied over the fin on the outside. The interior may have a drywall return from the wall to the window frame. CAUTION: Many windows in older homes are painted with lead-based paint. Removal of old windows may disturb this paint. Proper precautions must be taken to minimize exposure to dust and debris. Consult state or local authorities and/or go to www.epa.gov/lead for more information. REMEMBER TO USE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT. A. Score paint or varnish between the interior trim and the wall with a sharp utility knife. NOTE: This will minimize the damage to the interior wall and trim. B. Remove the interior trim. Using a pry bar and block of wood, remove the interior trim from all four sides of the window including the stool at the bottom of the window. If the interior trim is being reused, pull the nails out through the back side of the board with nipper pliers. C. Cut the exterior sealant line between the exterior brickmould or trim and the exterior siding or wall cladding. D. Remove the exterior brickmould or flat trim using a pry bar and block of wood. Caution: Some windows may come out of the opening as the exterior trim is removed. E. Remove the window frame using a pry bar if necessary. D. Remove the existing exterior trim (if applicable).

Cut 1" wide tabs at each corner by tearing the foil 1/2" each way from corner. E. Apply sill flashing tape #2 overlapping tape #1 by 1" minimum. If existing building wrap is folded into the opening at the jambs, skip to step 1H. F. Cut 2 pieces of flashing tape. Make one equal to the height of each side of the opening. G. Apply one piece on each jamb starting 1" from the exterior of the framing, over the edge of the sheathing and onto the surface of the sheathing. NOTE: PRESS ALL FLASHING TAPE DOWN FIRMLY. H. Install and level sill shims. Place 1" wide x 1/4" to 3/8" thick shims 1/2" from each side. Keep shims back from interior face of window. Place additional shims under each mullion and sliding window interlocker. For vinyl windows, add shims so maximum spacing is 18". I. Attach shims to prevent movement after they are level. NOTE: Improper placement of shims may result in bowing the bottom of the window. A. Insert the window into the opening on the sill spacers. Center the window between jambs. B. Drive two fasteners, one near each end of the top nailing fin. See the nail fin anchor instructions at the end of this booklet for fastener requirements. C. Plumb and square the window using shims at the locations shown. Adjust shims to plumb and square the window. Keep shims 1/2" short of window frame depth. NOTE: DO NOT shim above the window. Additional shims are required at screw locations for large units and combinations. See the nail fin anchor instructions at the end of this booklet. D. Check the window placement by measuring from the interior surface of the window frame or jamb extension to the interior surface of the wall for consistency. If the dimensions are not equal, confirm the fins are folded fully to 90º (if applicable). E. Drive two fasteners one near each end of the sill nailing fin. F. Check window operation. Vent awning and casement: See lock lever and crank handle instructions at the end of this instruction. Lift the lock lever and turn the crank handle to open the window. Remove the shipping spacers. Open and close the window to test for proper operation. Double Hung: Cut the checkrail bands (if applicable) and remove shipping spacers. Open, close and tilt the sashes to test for proper operation. Check for equal sash to frame reveal from top to bottom. NOTE: Adjust shims to correct any issues with plumb, square, operation or reveal. G. Close and lock the window. H. Finish driving fasteners into the nailing fin. Refer to the nail fin anchor instructions at the end of this booklet.

Follow the directions on the can. Do not use high pressure or latex foams. A. Insert the nozzle or straw between the rough opening and window frame from the interior. Use a pliers (if necessary) to compress the end of a straw tube to allow it to fit in tight openings. B. Place a 1" deep bead of foam approximately 1" from the interior of the frame to allow for expansion. DO NOT fill the entire depth of the rough opening cavity. NOTE: Apply foam between the frame and rough opening, NOT between jamb extensions and the rough opening. C. To ensure a continuous interior seal, apply sealant over the interior surface of any shims or clips interrupting the foam seal. Backer rod (as necessary) and sealant can be used in place of the low expansion foam to create the interior seal. However, foam has greater insulating properties. Fiberglass batt or similar insulation is not recommended as it can absorb water and does not act as an air seal. NOTE: Use a low odor, paintable sealant such as Pella Window and Door Installation Sealant. Re-check window operation and remove shipping spacers after foam installation. Excess foam may be removed with a serrated knife after it cures. Exterior Sealant Instructions CAUTION: Use a high quality, multi-purpose exterior sealant such as Pella Window and Door Installation Sealant. Follow the directions on the cartridge. When applying siding, brick veneer , flashing, or other exterior finish materials, leave adequate space between the window frame and the material for sealant application. A. Insert backer rod 3/8" deep in the space around the window. Backer rod adds shape and controls the depth of the sealant line. B. Apply a continuous bead of sealant to the entire perimeter of the window. C. Shape, tool and clean excess sealant. When finished, the sealant should be the shape of an hourglass. NOTE: The siding details below apply to windows without a J-mould as part of the frame. The J-mould frame is only intended for vinyl or metal sidings where the siding is extended behind the J-mould portion of the frame. The J-mould should be removed and replaced with backer rod and sealant with all other siding or trim types.
