lites and glazing stops to maintain glass face clearances and to prevent sealant from extruding 
into glass channel and blocking weep systems until sealants cure. Secure spacers or spacers and 
backings in place and in position to control depth of installed sealant relative to edge clearance 
for optimum sealant performance.
B. Force sealants into glazing channels to eliminate voids and to ensure complete wetting or bond 
of sealant to glass and channel surfaces.

frequent intervals during construction, but not less than once a month, for buildup of dirt, scum, 
alkaline deposits, or stains; remove as recommended in writing by glass manufacturer.

3.2 PREPARATION
A. Coordinate setting drawings, diagrams, templates, instructions, and directions for installation of 
anchorages that are to be embedded in concrete or masonry construction. Coordinate delivery 
of such items to Project site.
3.3 INSTALLATION
A. Locate and place louvers and vents level, plumb, and at indicated alignment with adjacent work.
B. Use concealed anchorages where possible. Provide brass or lead washers fitted to screws where 
required to protect metal surfaces and to make a weathertight connection.
C. Form closely fitted joints with exposed connections accurately located and secured.
D. Provide perimeter reveals and openings of uniform width for sealants and joint fillers, as 
indicated.
E. Repair finishes damaged by cutting, welding, soldering, and grinding. Restore finishes so no 
evidence remains of corrective work. Return items that cannot be refinished in the field to the 
factory, make required alterations, and refinish entire unit or provide new units.
F. Protect unpainted galvanized and nonferrous-metal surfaces that will be in contact with 
concrete, masonry, or dissimilar metals from corrosion and galvanic action by applying a heavy 
coating of bituminous paint or by separating surfaces with waterproof gaskets or nonmetallic 
flashing.
G. Install concealed gaskets, flashings, joint fillers, and insulation as louver installation progresses, 
where weathertight louver joints are required. Comply with Division 07 Section "Joint 
Sealants" for sealants applied during louver installation.
