Installation Instructions

1.0 Introduction

This installation/training guide is designed to assist a Pro-Flex® qualified installer

in the methods and procedures for the installation of flexible gas piping (CSST).

The installer

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

administrative authority administering the provisions of the code where the gas

piping is installed.

It would be impossible for this guide to anticipate and cover every possible variation in housing

configurations and construction styles, appliance loads and local code requirements. Therefore,

there will be applications that are not covered in this document. The user should exercise good

judgement on system design and installation, or seek technical input from other qualified

sources.

Where a conflict exists between this guide and local requirements the local codes shall

take precedence. In the absence of local codes, in accordance with National Fuel Gas

Code,

ANSI Z223.1 in the USA, /NFPA 54, Natural Gas and Propane Installation Code,

CSA B149.1 & B149.2 in Canada, and the International Fuel Gas Code. In cases where the

requirements of the guide are in conflict with the local code, the local code must take

precedence, unless the local code authority having jurisdiction approves a variance, or

change.

Special attention must be given to the proper design, installation, testing and use of the

gas piping. Sound engineering, principles and practices must be exercised, as well as dili-

gent adherence to the proper installation procedures. All installed systems must pass cus-

tomary installation inspections by the administrative authority prior to being placed in

service.

Improper installation or operation of the system may result in fire, explosion, or asphyxia-

tion. 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 ar

e to be used in the installation. Use of

components from other flexible gas piping systems other than those specified as part of

the Pro-Flex® piping system is prohibited and may result in poor system performance and

serious bodily injury or property damage.

The installation instructions and practices outlined in this training guide only apply to the

use of Pro-Flex® CSST flexible gas piping systems. Tru-Flex Metal Hose Corp., assumes

no responsibility for installations made with other manufacturers flexible gas piping sys-

tems.

This installation/training guide has been written in accordance with the most current edi-
