Proceed with installation only after unsatisfactory conditions have been corrected. <br />3.2 PREPARATION <br />A. Clean glazing channels and other framing members receiving glass immediately <br />before glazing. Remove coatings not firmly bonded to substrates. <br />3.3 GLAZING, GENERAL <br />A. Comply with combined written instructions of manufacturers of glass, sealants, <br />gaskets, and other glazing materials, unless more stringent requirements are <br />indicated, including those in referenced glazing publications. <br />B. Glazing channel dimensions, as indicated on Drawings, provide necessary bite on <br />glass, minimum edge and face clearances, and adequate sealant thicknesses, with <br />reasonable tolerances. Adjust as required by Project conditions during installation. <br />C. Protect glass edges from damage during handling and installation. Remove <br />damaged glass from Project site and legally dispose of off Project site. Damaged <br />glass is glass with edge damage or other imperfections that, when installed, could <br />weaken glass and impair performance and appearance. <br />D. Apply primers to joint surfaces where required for adhesion of sealants, as <br />determined by preconstruction sealant-substrate testing. <br />E. Install setting blocks in sill rabbets, sized and located to comply with referenced <br />glazing publications, unless otherwise required by glass manufacturer. Set bl ocks <br />in thin course of compatible sealant suitable for heel bead. <br />F. Do not exceed edge pressures stipulated by glass manufacturers for installing glass <br />lites. <br />G. Provide spacers for glass lites where length plus width is larger than 50 inches as <br />follows: <br />1. Locate spacers directly opposite each other on both inside and outside faces <br />of glass. Install correct size and spacing to preserve required face clearances, <br />unless gaskets and glazing tapes are used that have demonstrated ability to <br />maintain required face clearances and to comply with system performance <br />requirements. <br />2. Provide 1/8-inch minimum bite of spacers on glass and use thickness equal to <br />sealant width. With glazing tape, use thickness slightly less than final <br />compressed thickness of tape. <br />H. Provide edge blocking where indicated or needed to prevent glass lites from moving <br />sideways in glazing channel, as recommended in writing by glass manufacturer and <br />according to requirements in referenced glazing publications. <br />I. Set glass lites in each series with uniform pattern, draw, bow, and similar <br />characteristics.
