Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained through your EFCO
representative.
Condensation will form on any surface when unfavorable conditions (interior temperature and relative humidity and
exterior temperature) are present. When the formation of excessive condensation is a concern, it is highly recommend ed 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 condensation. Though not all
inclusive, the list of examples below illustrates conditions under which condensation is lik ely to occur:
1. Bridging system thermal break with non-thermally broken metal flashing or lintels th at 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 breaks
of one or all products involved
Note: Assembly Instructions are provided as a supplement, and should be used in conjunction with the approved shop drawings.
1. Below illustrates the recommended hardware locations for various unit config urations.
2. The exact lock locations and quantities will be determined on a job by job basis and will vary with the design
pressure and vent configuration for a given project. Refer to the final approved shop drawings for quantities and
locations. Snubbers at the vent head may not be required depending on structural loads and the size of the vent.
3. Opening limiting hardware is required for all vent installations. The maximum opening size for vents will be
determined by local code, but may not exceed more than opening at a 20 degree angle normal to the plane of the
wall for safety reasons.

7. If sealant primer is required, apply it per the primer/sealant manufacturer’s instructions. See the note in Figure 167 below.
8. Frames must be true and square before being structurally glazed. Improperly squared units will cause significant problems during vent operation. Check the frame for
squareness by comparing the difference between the two diagonal measurements of the frame by measuring from corner to opposing corner for the two diagonal
dimensions. The vent frame must be absolutely square for glazing.
9. Apply WS10 offset spacer gaskets to the vertical sash members. Ensure the gaskets are applied as shown in Figures 168 and 169 and are flush with the side of the sash
at the D.L.O. WS10 runs through vertically at the corners, with the WS10 at the head and sill running in between. Cut the gasket long, so it can be trimmed flush with the
horizontal gaskets, as shown in Figures 170 and 171. Notch the gasket dart on each end of WS10 to clear the miter at the corners of the frame.
10. Apply the WC18 offset spacer gasket to the head and sill sash member. The horizontal gaskets run between the WS10 gaskets at the vertical sash members.

Note: After cleaning and priming the glazing substrates (priming when required), the
glazing must be set and the structural silicone applied immediately. The time between
cleaning, priming, and applying the structural silicone should be less than two hours.
Otherwise, the substrates may become contaminated, and the primer will oxidize. If
units have been prepared for glazing at the end of the day, and sealant has not yet been
applied, cleaning and priming must be redone prior to glazing the next day.
Section 29 - Assembly and Glazing - Captured Vent at Stack Sill
11. Inspect the I.G. unit for the vent frame. Any excessive sealant or irregularities at the perimeter should be cleaned and trimmed. Check the glass for damage,
particularly along the glass edges and discard any unacceptable units. The secondary sealant joints of the insulated glass units should be checked for
proper size. The approved shop drawings will indicate the required secondary sealant joint size for the gl azing on the general information page. Check the
alignment of each pane making up the I.G. unit to ensure they are within acceptable limits. The I.G. unit overall dimensions should be verified for proper size.
12. Using an approved solvent or cleaner, thoroughly clean the edges of the glazing that will contact the structural silicone and spacer of all oils and other contaminants. Once the glass has been cleaned, it should be han dled with gloves or glass manipulator to avoid contaminating the edges that come
into contact with the structural silicone glazing joint.
13. Set the glazing on the silicone spacer gaskets positioned as shown below. The edge of the glazing is flush with the edge of the vertical sash as shown.
Refer to Figures 173 and 175 below. Ensure the glazing is positioned with the exterior side out, and the bottom of the glazing to the setting blocks. Care
should be exercised to avoid shifting or rolling the spacer gaskets when adjusting the position of the glass.
14. Temporarily insert the HS32 setting blocks between the sill sash fin and glazing to position the glazing to the sill. Remove the blocks after final alignment of
the glazing to apply the structural silicone. See Figure 174.
Section 29 - Assembly and Glazing - Captured Vent at Stack Sill
15. Apply structural silicone sealant into the void between the glass and mullion per the sealant manufacturer’s application instructions. See additional notes, and
figures below for sealant application and tooling instructions. A 90 degree nozzle may be required at the sill sash due to the fin bar at this location.
16. Immediately tool the sealant joint after application to insure the joint is completely filled with sealant on all four sides of each piece of glazing. Make sure no
air bubbles or voids are present in the sealant joint. See Figure 180.
17. Insert the HS32 setting blocks between the sill sash fin and glazing at quarter points or as directed per the final approved shop drawings. See Figure 174 on
page 70.

1. Measure and mark all centerline locations for the keeps and the snubbers. Refer to the final approved shop drawings and the factory order for locations.
2. Apply the snubbers at the head of the vent opening by inserting the tab of each snubber into the groove in the hardware reglet of the horizontal and rotate
into position. Align the snubbers, centered on the marked centerline locations and tighten the pinning scre w with an Allen wrench. The number and location
of snubbers will vary depending on vent size and design pressure. Snubbers will not be required for all vent configuration s. Refer to the final approved shop
drawings and the factory order for quantities and locations. See Figures 182 below, and 185-187 on p age 74.
3. Apply the keepers at the jambs and sill of the vent opening by inserting the tab of each keeper into the groove in the hardware reglet of the jamb adapters
and the sill and rotate into position. Align the keepers, centered on the marked centerline locations and tighten the pinning screw with an Allen wrench. The
number and location of keepers will vary depending on vent size and design pressure. Keepers will not be required at the jambs for all vent configurations.
Refer to the final approved shop drawings and the factory order for quantities and locations. See Figures 183 and 184 below, and 188-189 on page 74.

1. The figures below show a vent configuration for a SSG vent with a fixed horizontal at the vent sill. All other vent configurations will receive the WA07 preset
gasket in the same fashion. See Figures 197 - 200, page 77, 201 - 204, page 78, and 205 - 208, page 79.
2. Apply the interior WA07 preset gasket starting at the center of the head sash. The interior WA07 gasket wraps around on all four sides of the vent with one
continuous piece. Form as tight a radius as possible at the corners with the gasket. Ensure the gasket is not stretched during application. Butt the ends
together at the head, crowding in extra gasket to ovoid gaps later due to gasket shrinkage. See the Figures below and 194 - 196 on page 76.
3. Apply the exterior WA07 preset gasket to the jamb starting and ending 3” above the sill sash wrapping aro und the corners at the head. The exterior WA07
wraps around both jambs and the head on only three sides of the vent as one continuous piece. (See Figure 192).
4. Apply a piece of the WA07 preset gasket to the exterior leg of the sill sash of the vent that starts and stops 6” short of the jamb sash. See Figure 192 below.
