CHAPTER 4
INSTALLATION
4-1
INTRODUCTION
This section contains installation instructions for Kidde Fire Systems fixed carbon dioxide 
systems as well as hose reel and rack systems.
Equipment installation shall be such that the components are located and arranged to permit 
inspection, testing, recharging, and any other required maintenance that may be necessary. 
Components must not be located where they may be subject to severe weather conditions, 
direct sunlight, mechanical, chemical, or other damage which could render them inoperative.
4-2
GENERAL INSTALLATION REQUIREMENTS
Installation of Kidde Fire Systems fixed carbon dioxide systems shall comply with local and 
regional standards, be conducted according to accepted practices, and be performed in 
accordance with the approved installation drawings as well as with the instructions and 
information contained in this manual.

INSTALLATION OF SUPPRESSION SYSTEMS
4-3.1
Discharge Pipe and Fittings
Pipe, tubing, and fittings must be installed in strict accordance with the approved installation 
drawings and acceptable engineering practices. The piping between the cylinders and nozzles 
must be the shortest route possible, with a minimum of fittings. Any deviations in the routing 
or number of fittings must be approved by the design engineer prior to installation.
Piping and tubing must be reamed free of burrs and ridges after cutting, welding or threading. 
Joint compound tape or thread sealant must be applied only to the male threads of the joint, 
excluding the first two threads. Each pipe section must be swabbed clean, using a 
nonflammable organic solvent.
All piping must be blown out with nitrogen, carbon dioxide, or dry compressed air prior to 
installing the discharge nozzles. Dirt traps at least 2-inches (51 mm) in length must be installed 
1at the end of each pipe run. The piping system must be securely supported and braced to 
account for discharge reaction forces in addition to the load from piping deadweight and forces 
resulting from thermal expansion/contraction. Consideration must be given to thermal 
expansion/contraction by avoiding rigid restraints (anchors) at both ends of a long pipe run. 
One end of the pipe run must be supported with an intermediate type pipe hanger (refer to 
Pipe Design Handbook, Second Edition published by Fire Suppression Systems Association, 
Baltimore, Maryland), in order to avoid structural buckling or pipe joint or support separation 
due to thermal expansion/contraction. Care must be taken to insure the piping is not subjected 
to vibration, mechanical, or chemical damage. Refer to Table 4-1 and Table 4-2 for pipe 
support guidance.
Piping shall be of non-combustible material having physical and chemical characteristics such 
that its deformation under stress can be predicted with reliability. Special corrosion resistant 
materials or coatings may be required in severely corrosive atmospheres. Examples of 
materials for piping and the standard covering these materials are:
(a) Ferrous Piping: Black or galvanized steel pipe shall be either ASTM A-53 seamless or 
electric welded, Grade A or B, or ASTM A-106, Grade A, B, or C.
ASTM A-120, furnace butt-weld ASTM A-53 and ordinary cast-iron pipe shall not be used.
