Plenum Protection Nozzle: N-1HP (1 Flow Point) Coverage: Length: 12 feet (3.7 m) max. Width: 4 feet (1.2 m) max. Placement: Sea Figure 3.7. Aim point: See Figure 3.7. The Model N-1HP nozzle is a one (1) flow point nozzle that can protect a plenum (either single bank or V-bank) of 12 feet (3.7 m) in length and 4 feet (1.2 m) in width per nozzle. Larger plenums must be divided into 12 foot 13.7 m) sections, with each section protected vhth a separate nozzle. See Figure 3-7. Plenum: V-bank Nozzle Placement The nozzle must be located at the center of the V-bank width and down 1/3 of the vertical height, within B inches (15 cm) of the end of the plenum or plenum module and aimed down the length of the plenum. See Figure 3-7. Plenum: Single Filter Bank Nozzle Placement The nozzle must be located at a point that is 2" (5.1 cm) from the back edge of the filter and 113 of the vertical height of the filter, within 6 inches (15 cm) off the end of the plenum or plenum module and aimed down the length of the plenum.

Model N-1HP Plenum Nozzle Placement and Aiming Note: These examples are typical and do not represent every acceptable nozzle configuration, only a representative sample of them. Designer Note For plenums that exceed 12 feet (3.7 m) in length and therefore require multiple nozzles, it is recommended that the total length be divided into equally sized protection zones and protected accordingly. So a 16 foot (4.9 m) long plenum should be divided into two 8 foot (2.4 m) zones, with a nozzle protecting each, as opposed 10 a 12fcot (3.7 m) zone and a 4 foot (1.2 m) zone_ SPN: BFR-TM cq Chapter 3 — System Design Page 3 - 3 Revision 4 APPLIANCE PROTECTION Each different appliance must be protected in a specific manner with regard to nozzle selection, placement, and aiming. No deviations from these parameters are allowed and failure to comply completely with these requirements will void the UL Listing of the system and may render the system ineffective. In order to properly understand this section, several key terms need to be defined in advance. DESIGN TERMINOLOGY Nozzle Height: The distance from the tip of the discharge nozzle to the top surface of the appliance (except for woks, in which case the bottom of the wok is used). Hazard Area: All nozzle coverages include the maximum size of the hazard area they can protect. Hazard area is NOT the overall size of the appliance being protected, but rather the actual size of the portion of the appliance used for cooking. Aoatiances Requiring Multiple Nozzles Some appliances may need to be protected by multiple nozzles because of their size. If the size of an appliance is larger than the approved coverage for that appliance, multiple nozzles must be used. This is accomplished by dividing the hazard area into individual zones that comply with the parameters of the listing for that appliance. In this case, each zone will be protected as an individual appliance with respect to nozzle placement and aiming. RANGE PROTECTION Two (2) Bumer Range — LOW Proximl Nozzle: N-1LP (i Flow Point) Coverage: 12" (30.5 cm) x 24" (61 cm) Maximum (measured bumer edge to burner edge) Nozzle Ht: # 6" (41 cm) — 30' (76 cm) Placement: 3" (7.6 cm) from either edge of appliance, on appliance's tong centerline. Aimpoint 6" (15 cm) from opposite edge of appliance, on appliance's long centerline. The Model N-1LP nozzle is a one (1) flow point nozzle that can protect a range cooking area of 12" (30.5 cm) wide by 24" (61 cm) deep. The nozzle must be located 16' (41 cm) to U' (75 cm) above the cocking surface and positioned on the appliance's long centerline within ULEX 6085 ULC-EX 6885 January 1, 2011
