ATTENTION

The installation of PRO-FLEX

Corrugated Stainless Steel

Tubing (CSST) must be performed by a qualified installer who

has been trained in the use of the Pro-Flex

system. The installer

must also meet all qualifications required by the state and/or

local administrative authority administering the provision of the

code where gas piping is installed.

This Installation/Training Guide provides the user with a general

guidance when designing and installing fuel gas piping systems

using PRO-FLEX

CSST gas piping. This guideline must be

used in conjunction with all local building codes. Local

requirements will take precedence in the event there is a conflict

between the guideline and the local codes. The installation shall

be made in accordance with local codes, or, in the absence of

local codes, in accordance with National Fuel Gas Code, ANSI

Z223.1/NFPA 54, Natural Gas and Propane Installation Code,

CSA B149.1& B149.2 in Canada, the International Fuel Gas

Code, the Federal Manufactured Home Construction and Safety

Standard, 24 CFR Part 3280, the Manufactured Housing

Construction and Safety Standards, ICC/ANSI 2.0, or the

Standard on Manufactured Housing, NFPA 501, as applicable.

Special attention must be given to the proper design, installation,

testing and use of the gas piping system. Sound engineering

principles and practices must be exercised, as well as diligent

adherence to the proper installation procedures. All installed

systems must pass customary installation inspections by the

administrative authority prior to being placed in service.

WARNING!

Improper installation or operation of the system may result

in fire, explosion, or asphyxiation. Only the components

provided or specified by Tru-Flex Metal Hose Corp., for the

use of Pro-Flex

as part of the fuel gas system are to be used

in the installation. Use of components from other flexible gas

piping systems other than those specified as part of Pro-Flex
