12. PROPRESSG™
12.1 Welcome
By choosing to install a CSA LC-4
approved ProPressG System for natural
gas, liquid proprane gas, or fuel oil,
you have joined the ranks of installing
contractors across the country who
believe there is no substitute for quality.
Viega has a history of bringing high
quality and innovative technology to the
contruction marketplace in the United
States. As with the companion ProPress
System, Viega fittings and
RIDGID
®
tools make it a ProPressG System.
Our engineers research and develop
complete systems that provide you, our
customers, the most effective and easy-
to-use products available.
The ProPressG System is a fast, safe
and reliable way to install natural gas,
liquid propane and fuel oil systems with
type K and L copper tubing. It provides
the added benefit without flames or
brazing while making connections in
seconds, keeping projects on time and
within budget.
Using an HNBR sealing element
designed to last the life of the
tubing, the ProPressG System also
incorporates the Smart Connect feature.
If a connection is left unpressed,
leakage of liquids and/or gases from
inside the system past the sealing
element is assured during pressure
testing. The Smart Connect feature is
removed during the pressing process
creating a leak-free permanent
connection. Built to last – fittings are
thicker than type K copper and meet
the most rigorous testing standards and
codes in the United States and Europe.
In the following pages you will be
guided through the installation
process of the ProPressG System.
You will then understand why this is
the fastest and most reliable form of
fuel gas installation.
12.2 Intent
This publication is intended to provide
information and guidance to design and
installation professionals with regards to
copper tubing systems using ProPressG
fittings for fuel oil, natural gas, liquid
propane gas and fuel oil piping systems.
States and local jurisdictions throughout
the United States have adopted either
the National Fuel Gas Code (NFPA
54 for Natural Gas, NFPA 58 for LP
Gas), the International Fuel Gas Code,
or the Uniform Plumbing Code. Local
gas utilities may have additional
requirements for use within their
jurisdictions. Designers and installers of
fuel gas piping systems should check
with the building department and local
gas utilities to identify the code and/
or standard regulating fuel gas piping
installations within the jurisdiction.
12.3 History
ProPressG has been used in Europe
since 1999 and in the U.S. since
2004. (ProPress has been used in
Europe since the late 1980s and in
the U.S. since the late 1990s for a
variety of applications.) Both
systems are backed by two plumbing
leaders, Viega and the Ridge Tool
Company, with a combined
excellence of over 175 years.
