A plate support assembly is to be attached only to non-combustible <br />construction such as biock, concrete or steel with clearance that is <br />adequate for installation and access. <br />DO NOT ATTACH THE PLATE SUPPORT TO COMBUSTIBLE <br />CONSTRUCTION. <br />For maximum support, the en6re perimeter of the plate support assembly <br />must be attached to structural framing (see Fig. 21). Structural members <br />are supplied by the installer. <br />FIG. 21 - SECTIONAL DETAIL FOR PLATE SUPPORT <br />FIG. 23 - WALL SUPPORT ASSEMBLY ASSEMBLED <br />VIEV1/ <br />HALF CLOSURE <br />BAND <br />:LAMP FLANGE <br />CASING <br />STRUCTU <br />BRACING <br />(BY OTHERSI <br />FULL ANGLE RING IIPICFAR) AND HALF ANGLE <br />RING (IPICHAR) <br />The full angie ring is used as a guide to prevent the Grease Duct iran <br />flexing due to latera! loadng. The angle ring is split for ease of ins411ation. <br />The I.D. of angle ring is slightly larger than the outside diameter of the pipe <br />casing to allow movement of the pipe inside the ring (see Fig. 22). <br />FIG. 22 - FULL ANGLE RING & HALF ANGLE RING <br />0 <br /> 0 0 <br />HAIF ANGLE RING <br />0 <br />a o <br />FULL ANGLE RING <br />The half angle ring is used as a saddle in haizontal or sloped runs. It <br />may be suspended either on rigid framework or soft irames, such as <br />threaded rod. The half angle ring will not replace a plate support or other <br />fixed support in horizontal runs. It should not be used as the sole support <br />for the Grease Duct. <br />WALL SUPPORT ASSEMBLY (IPICWSA) <br />A wall suppott assembly consist of a full angle ring, two clamp rings, wall <br />brackets and struts. The clamp rings sandwich a flange band at a pipe <br />joint and are supported by the full angle ring (see Fig. 23 & Fig. 24). <br />CLAMP RING <br />PLATE SUPPORT <br />BRACKETS <br />NOTE: Wrap pipe joint with insulation before attaching half ciosure bands <br />The clamp rings are installed with the splits 90° apart so that they support <br />each other. The notches in the ciamp rings are aligned with the draw <br />saews of the flange band. The ciamp rings and full angle ring are then <br />bolted together with the hardware provided to fam a rigid assembly (see <br />Fig. 24). <br />FIG. 24 - WALL SUPPORT ASSEMBLY EXPLODED VIEW <br />When attached to a non-canbustible wal1, with the brackets and struts, the <br />wall support makes up a fixed-point in the Grease Duct An expansion joint <br />is required beiween the wall support assembly and any adjacent fixed <br />point. <br />Multiple wall support assemblies may be used, in conjunction with <br />expansion joints, to support Grease Duct heights in excess of the allow <br />able height for a single wall support assembly. <br />DO NOT ATTACH THE WALL SUPPORT ASSEMBLY TO <br />COMBUSTIBLE CONSTRUCTION. <br />10 <br />
