WV410 WINDOW - INSTALLATION INSTRUCTIONS Section I – Product Description and Limitations The WV410 storefront window system is designed and engineered to be field glazed and installed with a limited amount of labor and tools. Although the WV410 window is designed to complement the S401, S402, S403, and S433 center set systems, it may be glazed into any system with a smooth surface opening that has a minimum depth of 3 7/16”.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section III – Standard Parts Identification Detail Part No.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section IV – Size Formulas A. Window and Glass Size Formulas There are three (3) different configurations of the WV410 window system. Each of the configurations will determine the horizontal dimensions of the glass and individual units. Note: The storefront D.L.O. horizontal and vertical dimensions must be known to calculate the sizes. Glass and window size formulas for the WV410 units are provided below for each configuration.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section IV- Size Formulas B. Egress Formulas Egress openings must be figured based on the clear opening after the vent is opened to the 90 degree position. See the figures and equations below for window sizes at the egress opening. Use standard window sizing requirements as shown on Page 5 once the egress has been used to determine the storefront D.L.O. size. Egress Windows must use LA01 Arms Only! STOREFRONT D.L.O. EGRESS OPENING = STOREFRONT D.L.O.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section V – Captured WV410 Vent Glazing Step 1 Unlock the cam locks and open the vent to expose the hardware. Remove the vent from the WV410 frame by removing the screws from the hinges. Be sure to mark the vent to correspond with the appropriate frame. This will insure that the vent is reinstalled correctly. Step 2 Lay the vent face up on a flat, smooth working surface. Remove the glass stops from the vent.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section V – Captured WV410 Vent Glazing Step 8 Reinstall the glass stops. The glass stops are designed to be inserted into the vent material and rotated up and out toward the edges to lock into place. Insert a 3” long temporary piece of the glazing wedge WEB5 at the midpoint of each stop until all four (4) are in place. See Figure 3.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VI – SSG WV410 Vent Glazing Step 1 Unlock the cam locks and open the vent to expose the hardware. Remove the vent from the WV410 frame by removing the screws from the hinges. Be sure to mark the vent to correspond with the appropriate frame. This is to insure that the vent is reinstalled correctly. Step 2 Lay the vent face up on a flat, smooth working surface. Step 3 Make sure that the glazing surfaces of the vent are free from oil and metal shavings.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VI – SSG WV410 Vent Glazing Step 7 Insert two (2) HN91 - 3/16” x 1” x 4” setting blocks on each side of the glass 6” from the corners, as required, based on the configurations shown in Figure 7. Adjust the blocks as required to keep the vent square. Step 8 Insert backer rod material between the glass and the vent material around the entire perimeter except at setting block locations.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VII – Vent Gasket Preparation The exterior weatherstrip flap is to be trimmed at the sill to jamb corners. Trim the weatherstrip 3” from the sash corner both horizontally and vertically. This gasket preparation applies to both Captured & SSG versions of the WV410 vents. See Figure 9. Figure 9 EFCO CORPORATION 2/2014 PART NO.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation A. Single Window Installation Step 1 Locate the 1/32” inset for the WV410 frame at the horizontal mullions of the storefront D.L.O. Step 2 The WV410 frame is mounted into the storefront opening by first drilling and countersinking attachment holes. Drill .201” diameter (No. 7 drill) mounting holes at the WV410 frame and countersinking for No. 10 FH-SMS SFP1 screws, 4” from the ends and 16” on center maximum.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation B. Dual Window Installation The procedure for installing the vertical mullion in a dual window application differs from the ribbon run application. In a dual window application, the WV410 frame side clearances are ample enough to install the windows after the vertical mullion. In a dual window application the mullion is always installed first. Step 1 Establish the mullion center lines in the opening per the approved shop drawings.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation B. Dual Window Installation Step 3 At the predetermined mullion locations, drill and tap the storefront horizontals for two (2) MRF7 10-24 PH-SMS fasteners. See Figure 15 below. # Shear block and all screws are included in the K320 package. (2) required per mullion. Figure #15 K320 #MRF7 #1F10 #SPC6 #9837 Interior of Storefront Detail G C/L of Mullion DETA IL G 7/8 in [.874] * Drawings on this page are not to scale.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation B. Dual Window Installation Step 7 Install the male portion 9837 of the mullion over the shear blocks and snap into the female portion of the mullion. Attach the male mullion half to the shear blocks with (1) SPC6 fastener at each end. See Figure 15 on page 13. Step 8 NOTE: Do not complete this step unless you are prepared to install the window into the prepared openings. Seal around the top and bottom edge of the mullion.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation C. Ribbon Window Installation The legs of the window engage the tracks of the vertical mullions, allowing a positive location situation for the windows. The ribbon run installation is the same as the dual window installation where the first mullion is installed prior to the WV410 frames. After the first mullion is installed, the remaining window and mullions will be sequentially stacked. See Figure 18.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation C. Ribbon Window Installation Step 1 Follow the procedures detailed in Steps 1 through 10 of pages 12 through 14 for the first mullion and WV410 frame. Step 2 After the first and second WV410 frames have been installed, the method of installation will differ from the previous steps. Beginning at the exposed jamb of the second WV410 frame, seal around the top and bottom of the WV410 frame where it meets the storefront horizontals.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation C. Ribbon Window Installation Step 3 Apply sealant to both ends of the female half of the mullion and apply to the interlock of the WV410 frame. See Figure 20 on page 15. Step 4 Install one (1) K320 shear block and two (2) MRF7 screws at the top and bottom horizontal. NOTE: The screw holes must be predrilled and tapped for screw insertion. Due to the available space within the mullion, a long handled screwdriver is recommended.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section VIII – Window Installation C. Ribbon Window Installation Step 8 Install the next WV410 frame by aligning the interlock of the window with the mullion interlock. Step 9 Shim the WV410 frame into the correct location and anchor to the opening at the top, bottom, and mullion side at the recommended locations covered in Steps 2 through 3 on Pages 16 and 17.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section IX – Casement Lift Block Installation Due to the weight of the vent, lift blocks are used to elevate the vent upon closing. Elevating the vent aligns the gaskets and cam locks to the proper location. All WV410 casement vents receive one (1) or two (2) pairs of lift blocks, depending on the vent size. Casement vents over 30” wide will receive two (2) pairs and vents under 30” will receive one (1) pair.
WV410 WINDOW - INSTALLATION INSTRUCTIONS Section X– Vent Removal and Adjustment Unlock the vent and open the operable vent far enough to expose the hinge attachment screws STT5 at the WV410 frame. See Figure 25. Support the vent and remove the six (6) hinge attachment screws from the WV410 frame. Note: If the vent is equipped with an optional limit stop, this will need to be removed before the vent will open far enough to expose the mounting screws. The vent can now be removed from the exterior.
