WALL GUIDE QPICWG) <br />The wall guide is designed to compiiment the wali support assembly. It is <br />used as a lateral support to prevent the Grease Duct from flexing due to <br />lateral loading. <br />The wall guide consists of a full angle ring with wall brackets and struts <br />(see Fig. 25). <br />FIG. 25 - WALL GUIDE <br />SPECIAL CONSIDERATIONS <br />When a wall support assembly is used to support a Grease Duct on an <br />e~erior wall, wind loading must also be considered. Below the highest wall <br />suppo~t assembly, the Grease Duct must be resupported at intervals not <br />greate~ than 40' (12.19m). The Grease Duct must be equipped with wail <br />guides between each wall support assembly. Guide spacing is in <br />accordance with dimension "A" in Table 5 on Page 13. Additionally, a wall <br />guide must be located beiween 6' and 10' {1.83m and 3.05m) below the <br />highest wall support to stabilize the freestanding portion of the Grease <br />Duct above the wall support assembly (see Fig. 27). <br />FIG. 27 - SPECIAL CONSIDERATIONS FOR GREASE DUCT <br />OUTSIDE WALL <br />HORROP <br />S1 <br />.OCATE BELOW <br />)UTER BAND <br />J~1GLE TO BE <br />~DJU5TED AS <br />IECESSARY <br />OR PHOPER <br />'~LEARANCE <br />WALL SUPPORT <br />DO NOT INSTALL AN <br />EXPANSION JOINT IN <br />THIS AREA DUE TO <br />BENDING FORCES <br />WALL GUIDE <br />The proper location for a wall guide is immediately below the outer closure <br />band near a pipe joint The outer band must be abie to move away from <br />the wall guide when thermaf expansion occurs (see Fig. 26). <br />FIG. 26 - WALL GUIDE LOCATIONS <br />PIPE FLANGES <br />/ <br />162-306) <br />LOCATE EXPANSION JOINT <br />BELOW WALL GUIDE <br />FLOOR GUIDE (IPICFG) <br />The floor guide is similar in function to a wall guide or full angle ring, but is <br />modified specially for use at floor penetrations. The angle brackets and <br />straps hold the guide centered in the floor penetration (see Fig. 28). <br />FIG. 28 - FLOOR GUIDE <br />ANGLES <br />STRAPS <br />WALL GUIDE OR <br />FULL ANGLE RING <br />(STRUCTUFE BV OTHEHS) <br />PIPE <br />PENING <br />0' (2641 <br />11 <br />ATTACHMENTS <br />~--- MAXIMUM OPENING -~ <br />PIPE ~.D. + 10' (264) <br />
