Detailed Parts: PIPE LENGTH (IPIC9, IPIC18, IPIC30, IPIC42) Model IPIC Series 4G Grease Duct pipe is available in 4 standard lengths: 9" (229),18" (45~, 30" (762) and 42" (1067). Pipe sec6ons are joined, using appropriate sealant, to make up desired length of run. These sections may be modified by use of nipples or couplings to accept auxiliary equipment such as fire suppression or automatic cleaning systems. Consult factory or your local representa6ve to obtain infamation regarding such modifications. DUCT DRAIN (IPtCDR) Duct drains are equipped with a 1" (2~ NPT coupling, which is attached to the inner wall and extends through the outer wall to provide a path to drain grease, condensate or wash water trom the duct. A dam is attached to the inside of the inne~ uvall adacent to the coupling to channel the effluent to the drain. The duct drain is intended for use at the end of a hor¢ontal ~un where access and ~ainage is needed (see Fig. 3). The drain coupling must be connected to a grease trap or approved container (supplied by others).

It is intended for use as a drain point and access at the base of a duct riser (see Fig. 4). The drain nipple must be attached to a grease trap or approved container (supplied by others). NOZZLE SECTION (IPICNS? The noale section is used when the duct is required to be equipped with a fire suppression system or washdown is desired. The noale section allows a spray head or nipple to be attached to the duct through a 1" (2~ NPT coupling attached to the inner wall and passing through the casing. In hor¢ontal sections, the nozzle section must be installed so that the coupling is at or above the horizontal centerline of the pipe. When the pipe section is in a vertical orientation, the noale may be located at the most convenient place. Local authorities should always be consulted regarding the need for fire protec6on or washdown systems.

The outside dimensions of the square end are slightly smaller than the hood collar. It will fit inside the collar and be co~nected by means of a lap weld. Altematively, the square end may be equipped with a flange to be used for a bolted or welded connection in accordance with NFPA 96. FIG. 5- SQUARE TO ROUND ADAPTER OPTIONAL ANGLE FLANGE When ordering a square to round adapter, the s¢e of the square end, flange requirements and diameter of the round end must be specified. Note: Many hood manufacturers have the capability to build the hood with a round flanged collar, which matches the flange on Model IPIC pipe. Others can install a round flanged collar supplied to them or can provide a hood without a collar fw the hole to be field cut. These alterna6ves may avoid the necessity of providng a square to round adapter. (BV OTHERSI
