Series 875 Vent General Notes
1. MATERIAL HANDLING
The material must be protected against damage. The following precautions are recommended.
a. PROTECTION AND STORAGE: Handle the material carefully. Do not drop from the truck. Stack with adequate
separation so the material will not rub together. Store the material off of the ground. Protect against the elements
and other construction hazards by using a well ventilated covering as required. Remove material from packaging
if it is wet or is located in a damp area.
b. CHECK MATERIAL: Upon arrival, check all material, to ensure that the proper quantities have been received and
that material was not damaged during shipment. Any visibly damaged material must be noted on the freight bill
at the time of receipt. If a claim is required, the receiving party must process a claim with the freight supervisor.
c. CLEANING MATERIAL: Cement, plaster, terrazzo, alkaline and acid-based material used to clean masonry are
very harmful to finishes and should be removed with water and mild soap immediately or permanent staining will
occur. A spot test is recommended before any cleaning agent is used. For more specific cleaning informat ion
reference EFCO's General service and maintenance manual.
NOTE: If a protective coating is specified, remove it in areas that require sealant.
2. GENERAL NOTES: The following practices are recommended for all vent installations:
a. REFERENCE SHOP DRAWINGS: Check shop drawings and installation instructions to becom e thoroughly
familiar with the project. These installations instructions are of a general nature and cover the most common
conditions. The shop drawings take precedence and include specific details for the project.
b. CHECK OPENINGS: Make certain that construction which will receive your material is in accordance with the
contract documents. If not, notify the general contractor in writing and resolve differences before proceeding
with work.
c. BENCHMARK LAYOUT: All work should start from benchmarks and/or column cente rlin es as established by the
architectural drawings and the general contractor.
d. PLUMB / LEVEL / TRUE: All materials are to be installed plumb, level and true.
e. ISOLATION OF ALUMINUM:
Use a heavy coat of zinc chromate or bituminous paint to isolate aluminum
from direct contact with uncured masonry and other incompatible materials.
f. FASTENING: Refers to any method of securing one part to another or to adjacent materials.
g. SEALANTS: Must be compatible with all materials they contact, including other sealant surfaces. Consult the
sealant supplier for recommendations relative to solvent cleaning materials and procedu res, compatibility,
adhesion, priming, tooling and shelf life.
h. BUILDING CODES: Glass and glazing codes governing the design and use of products vary widely. EFCO does
not control the selection of product configurations, operating hardware, or glazing material s, and therefore
assumes no responsibility. It is the responsibility of the owner, specifier, architect, general contractor and the
installer to make these selections in accordance with local building codes.
i. SHIM SPACE INFORMATION: The nominal shim space is 1/8". The maximum shim space is 1/4".
j. SURROUNDING METAL: The surrounding framing shall be a minimum thickness of 0.080".
NOTE: Performance values are based on AAMA standard test size for each specific test configuration. Lock points
can be moved at the head by changing the rod length. If required a lock point can be added under the
handle by adding one Giesse cap head screw 02251K and one H15U keeper . When DLO is greater than
48" in height, one additional lock point is required per jamb at center of vent. If the vent is larger than test
size or the vent has hardware options other than what was used on the test window, some degradation in
performance may occur. Job specific sizes and hardware options can be tested with the appropriate
charges and lead times added to the schedule.

Series 875 Vent Installation
VENT FRAME PREPARATION
1. Do not fasten drapery tracks, ceiling supports or
Stool trims to windows.
2. Fasten window frame into minimum of 0.080"
thickness of framing.
3. Minimum anchor spacing:
a. No more than 6" from each side of frame joints.
b. No more than 18" on center between anchors.
4. Pre-drill using a 0.201 DIA. - #7 drill bit to make anchor
clearance holes in the vent frame. Make
sure screw heads can be reached when vent is installed.
5. Countersunk anchor holes may be required with some hardware combinations. All screw heads must
be sealed at sill.
6. When installing curtain wall pocket adapters, use silicone to seal in place as directed by instructions
and shop drawings.
VENT INSTALLATION
1. Consult curtain wall assembly instructions and shop drawings before vent installation begins.
2. Install optional vent frame retention clips (FM85) if required.
3. Make sure all curtain wall seals covered by the vent are done and tooled before vent installation.
4. Vent frame sizes: curtain wall clear opening -1/4” in both
directions. This will allow 1/8” shimming on all sides.
5. Apply a continuous bead of sealant around face of
curtain wall clear opening.
6. Perimeter sealant must be applied to SSG front legs
before frame installation.
7. Perimeter sealant on custom SSG units may be applied
and tooled down after vent frame installation.

Series 875 Vent Installation
8. Place vent on 1/8” shims in clear opening and push in to bed to sealant.
9. If optional clips (FM85) are used you may need to apply shims after placing the vent. A clear snap
should be heard at the head from the clips. Look inside to make sure the clips are seated before opening the vent.
10. Shim vent 1/8” on all sides as needed, making it plumb and
square in the clear opening.
11. Remove the sash if vents are installed horizontally in the
shop.
12. Install anchor screws as needed on all side while still maintaining a plumb and square frame.
13. Reinstall vent and adjust for plumb and square in frame.
14. Check vent operation and locking making necessary
adjustment to the hinges and friction shoes.
15. Seal over screw heads at sill and install backer rod
and sealant in interior gap as needed.
