Model GS2511, 5.6 K-factor Open Sprinklers Response
General Description
The GS2511, 5.6 K-factor nozzles are open (non automatic) directional spray nozzles, designed for use in water spray fixed systems for fire protection applications. They are external-deflector-type nozzles that discharge a uniformly filled cone of medium velocity water droplets. The GS2511, 5.6 K-factor are effective in covering exposed vertical, horizontal, curved, and irregular shaped surfaces in a cooling spray to prevent excessive heat absorption from an external fire, and to reduce the risk of structural damage or fire spread to the protected equipment. In some applications, depending on water design density requirements, The GS2511, 5.6 K-factor may also be used for fire control or extinguishment. The GS2511, 5.6 K-factor nozzles are available in a wide variety of orifice sizes and spray angles (included angle of discharge) to provide versatility in system design.
Notice
The GS2511, 5 , 6 K- f a c t o r nozzles described herein must be installed and maintained in compliance with this document, and with the applicable standards of the NATIONAL FIRE PROTECTION ASSOCIATION, and with the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices. The design of individual water spray fixed systems can vary considerably, depending on the characteristics and nature of the hazard, the basic purpose of the spraying system, the configuration of the hazard, and wind/draft conditions. Because of these variations as well as the wide range of available nozzle spray characteristics, the design of water spray fixed systems for fire protection must only be performed by experienced designers who thoroughly understand the limitations as well as capabilities of such systems. The owner is responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or product manufacturer with any questions.

Installation
The GS2511, 5.6 K-factor Nozzles must be installed in accordance with this section. General Instructions A leak-tight 1/2 inch NPT nozzle joint should be obtained by applying torque between 7 to 14 ft.-lbs. (9,5 to 19,0 N·m). Higher levels of torque may cause impairment of the nozzle. Step 1. With pipe-thread sealant applied to the pipe threads, hand-tighten the nozzle into the fitting. Step 2. Tighten the nozzle into the nozzle fitting using only the W-Type 11 Sprinkler Wrench (Figure 2). With reference to Figure 1, apply the W-Type 11 Sprinkler Wrench to the wrenching area
