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 r
equirements the local codes shall
take precedence. The installation shall be made in accordance with local codes, or, in the
absence of local codes, in accordance with the National Fuel Gas Code, ANSI Z223.1 /
NFPA 54, Natural Gas and Propane Installation Code, CSA B149.1, the International Fuel
Gas Code, the Federal Manufactured Home Construction and Safety Standards, 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. 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 are 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-
tion of the following standard:
“ANSI LC1a – 2009, CSA 6.26a – 2009 and ANSI LC – 1 – 2005, CSA 6.26 – 2005”.
