FULL FRAME REMOVAL WHEN PREPARING TO INSTALL A NEW NAIL FIN WINDOW
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.

TOOLS REQUIRED:
•Utility knife
•Phillips and Standard
screwdrivers
• Pry bar
•Circular saw
•Hammer
•Putty knife
REMEMBER TO USE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT.
EXISTING WOOD BRICKMOULD FRAME WINDOW
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
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.

INTERIOR AND EXTERIOR SEALANT
Interior Sealant Instructions
CAUTION: Use low pressure polyurethane window and door insulating foams. Follow the
directions on the can. Do not use high pressure or latex foams.
A
Interior
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
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.
B
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.

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.
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® and Pella® 350 Series Windows FRAMES—The vinyl frame may be cleaned using the same method as the glass. For stubborn dirt, a “nonabrasive" 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.
Use of inappropriate solvents, brickwash or cleaning chemicals will cause adverse reactions with window and door materials and voids the Limited Warranty.
Interior Finish (Wood Windows)
If products cannot be finished immediately, cover with clear plastic to protect from dirt, damage and moisture. 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.
• 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.
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.
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.
Care and Maintenance
Care and maintenance information is available by contacting your local Pella retailer. This information is also available at www.pella.com.
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.
