Transcription

1 (2-Way Horizontal and Vertical Joining) for Andersen 400 Series Tilt-Wash Double-Hung, Picture, and Transom Windows with Stormwatch Protection Congratulations! You have just purchased one of the many fine Andersen products. Proper assembly, installation and maintenance are essential if the benefits of your Andersen product are to be fully attained. Therefore, please read and follow this Instruction Guide completely. If your abilities do not match this procedure s requirements, contact an experienced contractor. You may direct any questions about this or other products to your local Andersen dealer, found in the Yellow Pages under Windows or call Andersen WindowCare service center at Monday through Friday, 7 a.m. to 7 p.m. Central Time and Saturday, 8 a.m. to 4 p.m. Central Time. Thank you for choosing Andersen. Impact Resistant Glass used by Andersen is not hurricane proof or shatter proof, and may not offer a high level of security. Proper installation of window and door units with impact resistant glass is as important to product performance as the glass. Every assembly and installation is different (windloads, structural support, etc.), and Andersen strongly recommends consultation with an Andersen supplier or an experienced contractor, architect, or structural engineer prior to the assembly and installation of any Andersen product. Andersen has no responsibility in regard to the post-manufactured assembly and installation of Andersen products. Use caution when working at elevated heights and around unit openings. Follow manufacturer s instructions for safe use of ladder and/or scaffolding. Failure to do so may result in injury or death. Follow manufacturer s instructions for safe operation of hand/power tools. Always wear safety glasses. Failure to do so may result in injury and/ or product damage. Windows and doors can be heavy. Use safe lifting techniques and a reasonable number of people with enough strength to lift, carry and install window and door products to avoid injury and/or product damage. Unless specifically ordered, Andersen windows and doors are not equipped with safety glass, and if broken, could fragment causing injury. Many laws and building codes require safety glass in locations adjacent to or near doors. Andersen windows are available with safety glass that may reduce the likelihood of injury when broken. Information on safety glass is available from your local Andersen dealer. Andersen Installation Flanges DO NOT take the place of standard window and door flashing. Unit must be properly flashed and sealed with sealant, and full width drip cap for protection against water and air infiltration. Use non-reflective flashings. Highly reflective flashing tapes can raise the surface temperature of the vinyl to the point where vinyl deformation and product damage may occur. Do not apply any type of film to glass. Thermal stress conditions resulting in glass damage could occur. Use of movable insulating materials such as window coverings, shutters, and other shading devices may damage glass and/or vinyl. In addition, excessive condensation may result causing deterioration of windows and doors. Andersen and all other marks where denoted are trademarks of Andersen Corporation Andersen Corporation.

2 Metal fasteners and other hardware components may corrode when exposed to preservative treated and fireretardant treated lumber. Obtain and use the appropriate metal fasteners and hardware as called out by the installation guide to fasten unit to any rough opening made from pressure treated and fire-retardant treated lumber. Failure to use the appropriate materials for the installation may cause a failure resulting in injury, property or product damage. Units must be installed according to the following installation instructions using Jamb Clips or product will not meet designated performance levels. Venting units are packaged with temporary operator/lock handles. Permanent operator/lock hardware is available in various styles and finishes from your local Andersen dealer. DO NOT apply Extension Jambs prior to unit installation. Use this guide for joining units horizontally and vertically. 2-Way combinations using 3/4" LVL Joining must be assembled unit-by-unit in rough opening. Combinations cannot exceed 10' x 6'. 10' 6' Exterior View 2-Way Horizontal and Vertical Joining Example Parts Included (1) Instruction Guide (2) 3/4" Joining Bracket (1) Exterior Trim Strip Additional Parts Required Drip Cap (full width) (1) 3/4" LVL Joining Strip (1) Screw Pack (2) 7-9/16" L-Bracket Exterior Trim Strip Component Identification 7-9/16" L-Bracket Tools and Supplies Safety Glasses Tape Measure Pencil Level Hammer Clamps Utility Knife Electric Drill Caulk Gun Sealant Vise Grip/Pliers Small Pry Bar Wood Shims Power Saw Hack Saw 3/32" Drill Bit Screw Driver Wood Chisel Hack Saw Shims Wood Blocks Isopropyl Alcohol 3/4" Joining Bracket 3/4" LVL Joining Strip 2

3 1. Verify that LVL is Adequate for Your Installation Calculate the average adjacent unit dimension ((A + B) 2). Determine the continuous mullion length (C). Use the windload table below to cross reference the average adjacent unit dimension with the mullion length to determine the windload performance of your combination. Be sure that this performance is adequate for your installation requirements. Refer to the Combination Design section in the Andersen Product Guide for Professionals for further information. C A B Design Windload PSF Table for 3/4" LVL Reinforced Joining Type of Combination: 2-Way For Combining: Andersen 400 Series Tilt-Wash Double-Hung, Transom, and Picture Windows Exterior View Average Adjacent Unit Dimension (A + B) 2 = 10' 1" (A + B) 2 = 9' 6" (A + B) 2 = 9' 1" (A + B) 2 = 8' 6" (A + B) 2 = 8' 1" (A + B) 2 = 7' 6" (A + B) 2 = 7' 1" (A + B) 2 = 6' 6" (A + B) 2 = 6' 1" PSF (A + B) 2 = 5' 6" (A + B) 2 = 5' 1" (A + B) 2 = 4' 6" (A + B) 2 = 4' 1" (A + B) 2 = 3' 6" (A + B) 2 = 3' 1" (A + B) 2 = 2' 6" (A + B) 2 = 2' 1" (A + B) 2 = 1' 6" C = (mullion length) 6'1" 6'6" 7'1" 7'6" 8'1" 8'6" 9'1" 9'6" 10'1" or less 3

4 2. Prepare Rough Opening 3/8" + Unit + 3/4" + Unit + 3/4" + Unit + 3/8" The use of building wrap and/or flashing materials will reduce the rough opening size. Adjust as necessary. Determine rough opening width for multiple units using the formula: rough opening width = 3/8" (shim) + total unit width(s) + 3/4" for each join (LVL Joining Strip) + 3/8" (shim). Determine rough opening height for multiple units using the formula: rough opening height = 3/8" (shim) + total unit heights + 3/4" for each join (LVL Joining Strip) + 3/8" (head clearance). Check rough opening for plumb and level. If rough opening is not plumb or level, correct as necessary. Check opening for square by measuring diagonally, upper left to lower right and upper right to lower left corner. If measurements are within 1/8, opening is square. If rough opening is not square, correct as necessary. For Horizontal 3/4" LVL Reinforced Joining, proceed to Step 6. For Vertical 3/4" LVL Reinforced Joining, proceed to Step 11. 3/8" + Unit + 3/4" + Unit + 3/8" Exterior View Level Tape Measure Exterior View 4

Apply Flashing Tape This instruction step depicts one of many options for proper flashing. Moisture infiltration problems in any type of building can be reduced by properly flashing and/or sealing around all building openings, including windows and doors. Proper flashing under and around window and door openings can reduce moisture problems, but the performance of any building system depends upon the design and construction of the building system in its entirety, which should address local environment, climate, building codes and product and material limitations. The design and installation of flashing and sealing systems are the responsibility of the architect, contractor, installer, and/or the manufacturer of the building exterior specified for the project. Apply flashing tape over Installation Flange at sill. Apply flashing tape over Installation Flange at sides, overlapping flashing tape at sill. Apply flashing tape over Installation Flange at head, overlapping flashing tape at sides. Flashing Tape Head (apply third) Sides (apply second) Exterior View Sill (apply first) 25

26 22. Seal Sides Apply sealant to sides where installation flange meets sides of units. 23. Insulate and Seal Unit When insulating between the unit frame and rough opening, DO NOT over pack batt insulation or overfill with expandable foam. Bowed jambs may result causing product performance problems and/or incorrect operation of unit. A minimum space of 1/4" is required around exterior perimeter of unit between the frame and exterior finish material to allow for material expansion. Masonry/Brick Veneer installations require a minimum 1/2" space along the sill and 1/4" space around remaining perimeter to allow for settling and expansion. Caulk Gun Backer Rod Sealant Insulate between frame and rough opening on all sides. DO NOT over pack or overfill with insulation; bowed jambs may result. Clean and prime around outside of unit where backer rod and sealant will be applied. Apply backer rod and sealant around exterior perimeter of window after siding (or other finish) is applied.
