USE AND INSTALLATION OF INDIVIDUAL PARTS FIG. These instruc6ons comprise both general and specific requirements for all parts in the Grease Duct product line. Before specifying a design or beginning an installation, these instructions should be carefully reviewed. PIPE WEIGHT The average weight of the chimney per lineal foot can be calculated using the following formula: IPIC-4G 1.65 X Diameter = Ibs. per foot Example: 81PIC-4G 1.65 X S= 13.2 Ibs. per foot Duct design should make sure that the Grease Duct is adequately supported to ensure parts are not overloaded. PART NUMBERS These instructions identify Model IPIC parts by name of part number in the te~ and il~ustrations. Actual parts also carry a flue dameter prefix and a three digit 'CTO" suffix which defines the materials of construc6on, such as 241PIC30-4AG for a 24inch diameter double wall pipe section 30 inches long with Type 304 stainless steel inner wall, Type Aluminized steel outetwall and a 4", S Ib. densiiy insula6on. (See Table 1 for further explanations of CTO codes).

All Grease Ductjoints must be liquid tight according to NFPA96. To insure that all joints meet that requirement, follow these six steps. 1. Apply a continuous bead of POSO~ealant to one of the flanges to be joined. NOTE: Sealant is supplied by Metal-Fab and in~vidual tubes are marked POSO. CAUTION: The use of any other sealant on the flange surface will negate all listings of the product and impair the sealing effectiveness. 2. Join the two flanged ends of the pipe section together. 3. Fill the channel of the flange band with P080 sealant. 4. Install the flange band around the flanges. NOTE: Light tapping with a hammer all around the band while tightening the end clamp bolt helps to aiign and pull the flanges together. 5. Install insulation strips (furnishec~ on sections to ensure that all air gaps are filled. Be sure that insulation completely fills the void between flue and closure band when assembled. 6. Secure the outer casing with the closure band. The pieces are then secure and air 6ght. 1 - JOINT ASSEMBLY ~ 2 3 ~ 4 5 6 FIG. 2- ASSEMBLED MODEL PIC JOINT OUTER PIPE INNER PIPE SEALANT ~ON INSIDEI SPACER CUP - OUTER CLOSURE BAND FLANGE BAND APPLY SEALANT TO INNER PIPE pL/WGES AND FLANGE BANO INSULATION NOTE: Do not attach outer band with sheet metal screws through outer casing.
