Sliding Patio Doors Operation/Screens/Grilles SLIDING PATIO DOORS Operation Thumbturn locking system You can find the thumbturn lock on the interior side of the flat panel behind the door handle. To lock the door, fully close the sliding panel and turn the thumbturn to a vertical locked position. To unlock the door, turn the thumbturn in the opposite direction. Unlocked Locked Screens Pella Impervia sliding screen doors are top-hung, which should provide years of easy operation because dirt and debris will not build up in the head track like it can on bottom tracks. To remove the screen door for storage, remove the two screen hanger screws in the top rail of the screen with a Phillips screwdriver (1). Tilt the top toward the interior, then lift up until the bottom guide is out of the sillframe track (2). To install the screen door, insert the bottom screen guide in the sill of the frame track. Keep the guide in the frame track, and tilt the top of the 1 2 screen up against the door panel. Align the two screen hanger screws with the holes in the screen carrier. Turn each screw approximately twice to adjust them (1). Turn the screw clockwise to raise the screen until the pile insect strip on the exterior of the screen s top rail touches the screen track. Slide the screen to within 1" of the lock side of the door. The space between the screen and the lock side of the door should be equal from the top to the bottom of the screen. If the space is not equal, adjust the screen hanger screws. Note: Do not adjust too high or too low, or the screen will not slide properly. Check the screen operation. Ensure the screen operates and latches smoothly. The lock on Pella Impervia sliding patio screen doors is operated manually. Slide the lever down to lock and up to unlock. WARNING: Use caution when children or pets are around open windows and patio doors. Screens are not designed to retain children or pets. Grilles Permanent grilles Aluminum grilles-between-the-glass The aluminum grilles-between-the-glass are permanently installed between panes of glass, so they stay clean and never need to be removed. 5.1
Cleaning Sliding Patio Doors Cleaning Cleaning the glass To wash the glass: 1. Use a premixed vinegar-based cleaning solution (or make your own with one part white vinegar to 10 parts water), and apply to a soft, clean, lint-free microfiber cloth or paper towel. Or you may use an ammonia-free glass cleaner such as Windex (clear liquid) or Sparkle (purple liquid). Feel free to be generous with the amount of cleaner you apply, but avoid getting any cleaning solution on the fiberglass frames as it may discolor the finish. 2. Rub from several different directions. 3. Rinse with clear water if streaks remain after cleaning. CAUTION: Do not use glass cleaners that are ammonia- or alcohol-based. They may leave streaks or produce a film that attracts moisture or dust. Spot-cleaning stubborn materials on all glass To remove any markings from grease, oil, tape adhesive, crayons or paint, or marks from plastics that may have come in contact with the glass: 1. Apply a small amount of a nonabrasive cleaner such as Bar Keepers Friend (SerVaas Laboratories) to a clean, wet cloth or apply a solvent such as acetone or mineral spirits to a clean, dry, lint-free microfiber cloth or paper towel. 2. Rub on the areas of glass that need spot-cleaning. Avoid getting any cleansers or solvents on the fiberglass frames as they may discolor the finish. 3. Wipe clean using a clean, dry, lint-free microfiber cloth or paper towel. 4. Then clean the glass as instructed above. CAUTION: Do not use a razor blade to scrape off stubborn materials doing so may leave permanent marks on the glass or scratches that could cause glass breakage. Contact the Pella Window and Door Showroom nearest you for special cleaning instructions. Spot-cleaning marks on a SunDefense Dual Low-E room-facing glass surface Occasionally, a mark may appear on the interior of Dual Low-E glass due to metal coming in contact with the surface.

Fixed Windows/Recommended Maintenance FIXED WINDOWS Operation/Cleaning Fixed windows are nonventing or nonoperable. Since the sash cannot be removed, the exterior must be cleaned from the outside. For additional cleaning instructions, please reference previous sections. RECOMMENDED MAINTENANCE Overview Pella Impervia Windows and Patio Doors Pella recommends you inspect your windows and doors at least annually as part of a home checkup. Recommended maintenance can prolong the life of your Pella Impervia windows and patio doors and will help ensure maximum warranty coverage. As needed, clean your windows and patio doors, and recaulk around the perimeter to help maintain optimal performance. Also be sure to check for leaks regularly, improper drainage above or around vents, and sprinkler systems that may subject your windows and doors to prolonged water exposure. With recommended care, Pella Impervia windows and patio doors and Special Shape windows can reward you with many years of beauty and performance. Exterior An annual checkup can help preserve and maintain the beauty of your Pella Impervia products for years to come. Inspect the sealant/caulking on the exterior perimeter of your windows and patio doors at least once a year. The sealant/caulking helps create a watertight seal between the window and door frames and the exterior siding (whether it is vinyl, cedar, aluminum, brick, etc.) or stucco. It is extremely important that the sealant/caulking remains intact and in good condition at all times. Pay particular attention to the caulking at the lower corners of windows and under joints between windows in combinations (a grouping of individual windows). The sealant material should not be cracked, broken or missing or it may cause premature failure of your Pella Impervia products or other parts of your home. Deterioration that occurs as a result of improper or insufficient maintenance is not covered by the Pella Impervia Limited Lifetime Warranty.* Pella Impervia windows and patio doors arrive prefinished. Check the paint, and if the surface is damaged, the exposed areas must be repaired immediately to prevent further damage. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest you. If you need further assistance, contact your local Pella representative. Please note that if you do paint over the factory finish, Pella s paint warranty is voided. Interior finish At least once per year, inspect the interior finish of your windows and/or doors to make certain that the finish is in good condition. UV rays from the sun can break down the finish and compromise its protective features. Pella Impervia windows and patio doors arrive prefinished.

Cleaning the weatherstrip To remove any deposits such as grease, oil or stains that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner such as Spray-n-Wash, OxiClean Fabric Cleaner or Resolve Carpet Cleaner to the weatherstrip. Scrub the cleaner into the weatherstrip with a toothbrush or similar applicator. Continue applying cleaner until the deposits are no longer visible. Rinse the weatherstrip with clean water, and dry with a paper towel. * See written warranty for complete details on Pella Impervia products, or visit http://warranty.pella.com. 6.1
Recommended Maintenance Double- and single-hung windows To remove any deposits such as grease, oil or stains that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner such as Spray-n-Wash, OxiClean Fabric Cleaner or Resolve Carpet Cleaner to the weatherstrip. Scrub the cleaner into the weatherstrip with a toothbrush or similar applicator. Continue applying cleaner until the deposits are no longer visible. Rinse the weatherstrip with clean water, and dry with a paper towel. Do not use oily lubricants to clean the weatherstrip; they attract dust and grime, which will eventually restrict the window s movement. Sliding windows Use the drapery brush attachment on your vacuum cleaner to clean the track. Do not use oily lubricants to clean the track; they attract dust and grime, which will eventually restrict the window s movement. Sliding patio doors For proper operation, keep the door track free of debris. The thumbturn lock and strike and rollers on the venting panel are adjustable to improve operation. Keep the weatherstrip clean and lubricated to enable the panel to operate smoothly. You may want to apply a thin coat of paraffin or other dry lubricant (Teflon Dry Lubricant or Gulf Wax, available at most home improvement stores, works well) to prevent sticking. Do not use oily lubricants to clean the track; they attract dust and grime, which will eventually restrict the door s movement. Sliding screen doors Pella screen doors are top-hung it is important to keep the upper and lower door track free of dirt and debris. The rollers on the top of the screen can be adjusted if necessary. (See page 5.1 for detailed instructions.) If the screen becomes dirty, you can clean it using a vacuum cleaner with the drapery brush attachment. Do not use oily lubricants to clean the track; they attract dust and grime, which will eventually restrict the door s movement. Salt spray environments The seacoast environment is extremely hard on all sorts of products (automobiles, recreational vehicles, building products, etc.). Any product used in a seacoast location will require more frequent inspection and maintenance to help it last as long as possible in this harsh environment. Windows and doors are no different from other products in this respect. If your home is in a coastal environment and is subjected to wind-driven salt spray or salt fog, use a mild detergent soap and water to clean the exteriors, including operating hardware, at least quarterly and more often if necessary to prevent salt or other abrasive materials from building up on the exterior surfaces. CAUTION: Do not power-wash. 6.2
Troubleshooting TROUBLESHOOTING Overview If you have a concern with your Pella Impervia product or need additional assistance from an experienced professional, consult your Yellow Pages (under Windows ) for the Pella Window and Door Showroom nearest you or use the store finder at pella.com. Glass breakage/damage In the event of glass breakage, consult the Pella Window and Door Showroom nearest you for assistance. Be sure to have your Pella Unit ID Number handy (see page 7.4). For safety reasons and to ensure optimum performance, we strongly advise you to consult a professional for glass replacement. U.S. federal law and most local codes require the use of tempered glass in doors and other specific applications. Tempered glass can withstand greater impact than ordinary glass, but it is sensitive to scratches. Scratches can cause immediate or delayed breakage. If the glass is tempered, it will break into small, rounded pieces. If tempered glass is broken, likely by law it must be reglazed or replaced with tempered glass. Sliding windows The sash is hard to open and close. The sash rolls on a track inside the frame. Over time, dirt and debris can get in or on the track, making it harder to open and close the sash. Removing the sash and using a vacuum cleaner with the brush attachment to clean out the debris in the track will make the sash easier to operate. The sash is hard to remove. Remove the venting sash. (See page 2.2 for detailed instructions.) On the bottom of the sash are two sets of dual nylon rollers. With needle-nose pliers, gently shift the wheels to the other notch location. This will raise the sash rollers by 1/16", allowing for the operating sash to move freely. Note: The roller housing does not have to be removed from the sash to adjust the roller location. This was done for illustration purposes only. Single-hung windows The sash is hard to open and close. The sash will slide inside the frame. Over time, dirt and debris can get in the frame, making it harder to open and close the sash. To remove any deposits such as grease, oil or stains that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner such as Spray-n-Wash, OxiClean Fabric Cleaner or Resolve Carpet Cleaner to the weatherstrip. Scrub the cleaner into the weatherstrip with a toothbrush or similar applicator. Continue applying cleaner until the deposits are no longer visible. Rinse the weatherstrip with clean water, and dry with a paper towel. Do not use oily lubricants; they attract dust and grime, which will eventually restrict the window s movement. Pella Impervia single-hung windows have a removable lower sash for easy cleaning. If these windows are not properly repositioned after washing, they may be difficult to open and close. (See page 3.2 for detailed instructions on how to remove the lower sash for cleaning.) 7.1
Troubleshooting Double-hung windows The sash is hard to open and close. The sash will slide inside the frame. Over time, dirt and debris can get in the frame, making it harder to open and close the sash. To remove any deposits such as grease, oil or stains that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner such as Spray-n-Wash, OxiClean Fabric Cleaner or Resolve Carpet Cleaner to the weatherstrip.

Rinse the weatherstrip with clean water, and dry with a paper towel. Do not use oily lubricants; they attract dust and grime, which will eventually restrict the window s movement. Pella Impervia double-hung windows tilt toward the interior of the home/building for cleaning. If these windows are not properly repositioned after washing, they may be difficult to open and close. Sliding patio doors The door latch does not always latch. The lock and strike are adjustable. Turn each of the four screws counterclockwise two turns. Adjust the strike up or down as necessary, and tighten the screws. The lock latch is adjustable to the left and right. The door does not slide smoothly. There are several possible causes. The track the door slides on may have debris on it, causing it to drag. If so, clean the track below the sliding panel. If this does not work, you may need to adjust the rollers to raise the door clear of the track. Adjust the rollers up or down to make sure the edge of the movable door is parallel to the side of the door frame. The adjustment holes are located on either side of the movable door, near the bottom. Remove the cap, and use a long-shaft Phillips screwdriver to adjust the rollers. Turn the adjustment screw clockwise to raise the end of the door, and turn counterclockwise to lower it. Replace the plastic caps. Once you adjust the door, you may need to adjust the lock strike up or down. See instructions above (under The door latch does not always latch ). Sliding screen doors The screen door does not slide smoothly. The screen should move smoothly on its track. Apply a thin layer of paraffin or other dry lubricant (Teflon Dry Lubricant or Gulf Wax, available at most home improvement stores, works well) to the track if necessary. Do not use oily lubricants; they attract dust and grime, which will eventually restrict the door s movement. The screen rollers can be adjusted by turning the screws located on the top of the door. If the screen door is too tight at the top, turn the adjustment screws counterclockwise to lower the door. Level the screen door so the edge aligns with the lock jamb of the frame. Preventing condensation Understanding condensation. Moisture is present in all homes, but when it becomes excessive, homeowners need to take an active role in protecting their investment. Humidity and condensation. Humidity is a measure of the amount of water vapor in the air. Condensation is water that forms when warm, moist air hits a cooler surface. In homes, it might occur on surfaces such as windows, bathroom walls and cold-water pipes. When interior humidity levels are too high, in relation to cooler outdoor temperatures, condensation can form on the coldest surface in a room often the glass in a window or door. While windows and doors do not cause condensation, they may be one of the first places it shows up. 7.2
Troubleshooting What causes condensation? Excess humidity is typically the cause of condensation. There are many sources for moisture in a home: showers, dishwashers, clothes washers and dryers, house plants, humans and pets, among others. In newly built homes, additional moisture may escape from building materials such as lumber, plaster and masonry for up to three heating seasons even with proper airflow and temperature management. Older vs. newer homes. Condensation may be less of an issue in older homes if conditions allow for more air exchange between indoors and out, often from around aging, loose or poorly installed windows and doors. However, the tradeoff is higher energy bills. When replacement windows are properly installed and the airflow around the window decreases, condensation may form on the glass of the new windows. Newer homes, on the other hand, are more airtight and energy-efficient. Many have vapor barriers plastic within the wall cavity blocking moisture passage in either direction. With tighter-fitting doors and windows, vapor barriers and increased insulation, energy costs are lower, but humidity levels must be monitored more closely. No matter when your home was built, the key is to strike the right balance when it comes to humidity levels. Air that s too dry can cause furniture to dry out and crack, joints and studs to shrink and twist, and paint and plaster to crack. Excessive moisture in the home can cause paint to peel and insulation to deteriorate, and condensation on windows and doors can damage sills and trim. Measuring and controlling humidity. To determine how much humidity is present in your home, you can purchase a humidity gauge from a hardware store or home center. Invest in a quality unit for greater potential accuracy in assessing humidity levels, or consult an expert. Another way to monitor the interior humidity level is to watch your windows. When interior condensation begins to form, wipe it off. To reduce the humidity, open windows, run exhaust fans or dehumidifiers, or minimize sources of moisture. The University of Minnesota Laboratories provides a chart showing recommended relative humidity levels for the home. Maximum Recommended Humidity Levels Outside Temperature Inside Humidity 20º F to 40º F Not over 40% 10º F to 20º F Not over 35% 0º F to 10º F Not over 30% -10º F to 0º F Not over 25% -20º F to -10º F Not over 20% -20º F or below Not over 15% Based on engineering studies at 70º F conducted at the University of Minnesota Laboratories. Exterior condensation. Exterior condensation on windows occurs primarily in the morning when days are warm and humid, but nights are cool. Typically, it clears as the day warms. Exterior condensation can occur at any time, especially in warm, humid climates where interior temperatures are cooler than outdoor conditions. Exterior condensation means that windows are doing their job properly. However, if you spot excessive condensation on the inside of your windows, check your inside humidity it may be a signal of potential problems if not addressed. Tips for wintertime moisture management. Open window coverings such as blinds, shades, drapes and curtains during daylight hours to increase airflow over the glass. Closely monitor the furnace humidifier and any other humidifying devices. Be sure louvers and vents for the attic, basement and/or crawl space are open, adequately sized and cross-ventilated. Run exhaust fans for the kitchen, bathroom and laundry rooms for longer periods. Make sure exhaust fans vent directly outside, not into attics or crawl spaces. Be sure chimneys are free and clear, so moisture in combustion gases can escape. Follow the manufacturer s instructions for venting gas appliances. In most cases, that will mean directing vents to the outside of the home. Make sure your furnace is in proper working order and is serviced regularly. Store firewood outside or in the garage as wood dries, it gives off moisture. Install energy-efficient windows, such as those that have earned the ENERGY STAR. 7.3
