EFCO 875X Wall Vent - Manual (Page 3)

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 information
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 become 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 centerlines 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 procedures, 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 materials, 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.
