NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appli- ance protection. A. Duct Protection It is not required that the fan be shut down or the exhaust duct be dampered for the system to operate properly. Each nozzle.is..approved to proteci_exhatisLc&c1s_of unlimited--- length. Duct protection requires that a nozzle by positioned to dis- charge up, into the duct. The nozzle is a Model 2D, Part No 551038. The Model 20 duct nozzle is a two (2) flow nozzle. A single 2D nozzle is capable of protecting square or rectangular duct with a maximum of 100 in. perimeter, with the longest side being a maximum of 34 in. It can also protect a round duct with a maximum diameter of 31 7/8 in. Two (2) Model 2D duct nozzles can protect a square or rec- tangular duct with a maximum of 150 in. perimeter, with the longest side being a maximum of 51 in. They can also pro- tect a round duct with a maximum diameter of 47 1/2 in. 2D NOZZLE 1,2it 4- 1/2L_Sl L -Figure 3-1. Transition Ducts - The protection of non-standard ducts should be reviewed by the authority having jurisdiction. Pyro-Chem Kitchen Knight II recommends that transition ducts be protected as follows: a. Transition ducts - larger to smaller In cases where the duct/plenum interface opening is larger than the final exhaust duct, measure the perime- ter/diameter of the duct halfway between the largest and smallest section (or the average perimeter/diame- ter). The nozzle is to be located within 0-6 in. of the duct/plenum interface (not at the point where the mea- surement was, taken), centered under the .final exhaust duct opening. See Figure 3-1a. When two (2) 2D duct nozzles are used to protect a single duct, the cross sectional area of the duct must be divided -----into-two-equal-symmetrical-areas.—The-nozzle-must-then-be_ - installed on the centerline of the area it protects and aimed directly into the duct opening. The nozzle(s) must be installed on the centerline of the duct, with, the tip located 0 to 6 in. into the opening, and aimed directly into the duct opening. See Figure 3-1. 008173PC Figure 3-la.

Standard duct nozzles are used in this application. See Figure 3-1d. B. Plenum Protection The Model 1H nozzle, Part No. 551029, is a one (1) flow nozzle used for plenum protection. A single 1 H nozzle can protect a plenum (with single or V-bank filters) 10 ft. long by 4-ft-wide.DividingiheJeiigth into sections equal to or less than 10 ft. in length and positioning a nozzle at the start of - each section can be done to protect longer plenums. On V-bank plenums, the nozzle(s) must be located at the cen- tec of V-bank width, 1/3 of the vertical height of the filters. On single filter bank plenums, the nozzle must e oca e in. from the back edge of the filter, 1/3 down from the vertical height. For either application, the nozzle must be located with- in 6 in. of the end of the plenum (or module) and aimed direct- ly down the length of the plenum. See Figure 3-2.

Each module must not exceed the maximum area allowed for a single nozzle. However, when utilizing multiple nozzle protection, the longest side allowed for a fryer with drip board can be used, regardless of whether the fryer has a drip board or not. The maximum size fryer that can be modularized is 864 sq. in. Design requirements for multiple nozzle fryers are broken down as follows: Once the nozzle placement and quantity of tanks has been determined, it is necessary to determine the piping configu- rations between the tank and the nozzles. This section con- tains the guidelines and limitations for designing the distribu- tion piping so that the wet chemical agent will discharge from the nozzles at a proper flow rate. These limitations must also be referred to when selecting the mounting loca- tion for the tanks. The maximum pipe lengths are based on internal pipe vol- ume. Each size tank is allowed a minimum and maximum total volume of piping, calculated in milliliters. 1. If the fryer includes any dripboard areas, measure both There is no need to distinguish between what portion of the - the_internalJength.ront to back) and width of the frypot piping is supply line and what portion is branch line.

Determine the area of both the frypot and the area of the overall vat by multiplying corresponding length and width dimensions. 2. Divide the frypot or overall vat into modules, each of which can be protected by a single nozzle, based on the maximum dimension and area coverage of the nozzle as specified in 'Design Chart." Volume Chart 1/4 in. pipe = 20.5 mls./ft. 3/8 in. pipe = 37.5 mls./ft. 1/2 in. pipe = 59.8 mls./ft. 3/4 in. pipe = 105.0 mls./ft. If the module considered does not include any portion of the dripboard, use only the maximum frypot area and maximum dimension listed in the "Design Chart.' Tank Chart If the module considered includes any dripboard areas, use both the maximum frypot area and dimen- sion listed in the "Design Chart", and the maximum overall area and dimensiffi1itéd I thDéiii -- Chart." 3. None of the maximum dimensions may be exceeded. If either the maximum frypot or the overall sizes are exceeded, the area divided into modules will need to be redefined with the possibility of an additional nozzle.
