Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained through your EFCO representative.
Condensation will form on any surface when unfavorabl e cond itions (interior temperature and relative humidity and exterior
temperature) are present. When the formation of excessive condensation is a concern, it is highly recomm ended that a design
professional is utilized to perform an analysis of the shop drawings to recommend the best possible installation methods. Please
contact your EFCO representative for information on EFCO's Thermal Analysis Services.
Many current installation practices lead to an increase in the possibility of the formation of condensati on. Though not all
inclusive, the list of examples below illustrates conditions under which condensation is likely to occur:
Vent Removal and Adjustment..……………..……..…….…………..…..….21
Minimizing Condensation
1. Bridging system thermal break with non-thermally broken metal flashing or lintels that are exposed to the exterior
2. System exposure to cold air cavities
3. Interior relative humidity levels not maintained at recommended levels, see EFCO’s “Understanding
Condensation” brochure
4. Inadequate separation between system and surrounding condition at perimeter
5. Product combinations during the shop drawing stage that result in bridging thermal brea ks
of one or all products involved

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”.
The WV410 allows the plane of glass to be equal to that of the S401, S402, S403, and S433
center set systems. The correct location or inset of the WV410 is easily found by measuring out
from the interior surface to the storefront 1/32”. This will allow a 1/32” offset from the storefront
face to the window frame. If the WV410 intermediate mullion is used, the interior face of the
mullion will align flush with the storefront horizontal.
Section II – General Statements and Definitions
The user is encouraged to read and understand all of the instructions prior to proceeding with
installation. These instructions define several configurations and methods of installation that may
or may not apply to your project.
The instructions covered in this manual are pertinent to the S401, S402, S403, and S433 systems.
Consult approved shop drawings for special applications not covered herein.
The following terminology will be utilized throughout these instructions and has been included to
better orient the reader to the areas discussed.
Storefront Opening: Storefront or other mounting surface for the window are typically called
D.L.O. (Day Light Opening).
WV410 Frame: The interior mounting and fixed portion of the operable window.
Vent: The operable and glazed portion of the window.
Intermediate mullion: The adaptor system designed to allow the windows to be stacked side by
side in a dual or ribbon application.
The steps and details on the following pages have been developed to aid in the assembly and
installation of the WV410 storefront window system.

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. Refer to the information given that corresponds with the appropriate configuration.

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!

EGRESS OPENING =
STOREFRONT D.L.O. - 8 3/8"
EGRESS OPENING =

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.
Step 3
Make sure that the glazing surfaces of the vent are free from oil and metal shavings. Clean the
glazing surfaces as needed with alcohol. (Do not use glass cleaners).
Step 4
Insert a continuous row of pre-shimmed gasket W174 around the vent perimeter glazing leg.
Insert the gasket beginning at each end of the frame and work toward the middle then work out
any waves toward the ends forming tight joints. Do not stretch the gasket.
Step 5
Run a continuous bead of structural silicone sealant behind the tape as shown in Figure 1.
Step 6
Keeping the glass level and centered within the vent material, lower the glass down into place.

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 2 above. Adjust the blocks as required
to keep the vent square.
