When using clean-0uts, always prevent leaks and assure that the Grease Duct functions as intended. The Tee Caps can be ordered with or without a drain and are assembled in the same manner as the sections (See FIG. 1). EXPANSION JOINT (IPICAL) The expansion joint may be used to compensate for thermal expansion and to make up odd lengths. It is essen6al that su~cient installed length be allowed to compensate for abnormal, as well as namal, operating con- ditions. The expa~sion joint cannot be used to carect misalignment or to compensafe for lateral movement or vibration. An e~ansion joint is comprised of: (1) a collar that is 5'/." (133) long with a flange and vee band at one end and a graphite impregnated ring gasket at the other; (2) a 30" {762) long tube, flanged at one end, which fits into the 5Y." (133) collar; (3) an outer jacket consisting of two half jacket as- semblies; and (4) loose insulation blank~t to 611 space between the tube and casing.

Loosen draw screw at gasket band and slide coilar toward flanged end of tube. Do not remove coliar from tube. 2. Slide unflanged end of tube into the upstream piece of pipe and make up joint between pipe and collar following the procedures outlined under headng PIPE AND FITTING ASSEMBI.Y on Page 3. 3. Pull flanged end of tube to the downstream piece of pipe and make up joint as shown (see FIG.12). 4. Cut insulation to desired length and wrap inner pipe ensuring that it is covered completely before attaching half jackets. 5. Wrap two half jackets around joint with bead at the downstream end and punched edge overlapping plain edge by approx'unate 3/4° (19). Note: For horrzontal installations the seams must be located at the top and bottom of tfie pipe, coat unpunched edge of casing with P077 sealant to waterproof the casing. 6. Install seff-drilling screws (supplied with jacket) at punched holed through both layers at overlap. Exercise care that half jacket edges do not align with c~aw screws on flange bands and that no screws por are installed in por6on of jacket which is over casing of adacent pieces of pipe (see FIG. 13). The screws shipped with the expansion joint are of the correct length to avoid penetra6ng the inner wall (flue) of the pipe. Do not use any other screws to attach the casing. FIG. 13 - EXPANSION JOINT CASING ASSEMBLY SCRE pNCLU HA(f JACKET ~ T 3/4' (191 Note: Do not screw through casing of adjacent pipe. NOTES: 1. It is recommended that the pipe on both sides of the expansion joint is supported a guided to assure that the e~ansion joint will not bind during operation. 2. Installation of an expansion joint adjacent to fittings, such as elbows, tees or wyes, is not recommended. However, it is not always possible to avoid these fittings. If an expansion joint must be joined to one of these fittings, the unflanged end of the tube should be away from the fitting and fitted into a pipe length in the manner described in the 7nstallation proce- dure above. 3. Expansion joint must be installed with a flange to flange length of not more than 22" (558). The minimum length for installation must take into account the amount of expansion that may occur during operation. Mini- mum length is calculated as follows: Expansion = Length (feet)/100 x Temperature Rise (°F)/100 Minimum Length = Expansion + 6" (152mm) It is recommended that the temperature used in the above formula be at least 300°F higher than the expected namal operating temperature. If inner tube is too long, it may be cut to length. Tube must be a minimum of 8" (203) longer than flange-to-flange length. Prior to installtion of cut pipe, remove all burrs to ensure t~at interterence does not occur. Check gasket to ensure that it fits snugly without binding on inner pipe.
