Leak Testing with Smart Connect
Unpressed connections are located by
pressurizing the system with air or water.
Leak testing with air can be dangerous
at high pressures. When testing with
compressed air the proper pressure range
is ½ psi to 45 psi maximum. Following a successful
leak test, the system may be pressure tested up to 200
psi if required by local code requirements or project
specifications.

WARNING
Read and understand all instructions
!
for installing Viega ProPressG fittings for fuel gas.
Failure to follow all instructions may result in
significant property damage, serious injury or death.
1.
Cut copper tubing at right angles using
displacement-type cutter or fine-toothed steel saw.
2.
Remove burr from inside and outside of tubing to
prevent cutting sealing element.
3.
Check seal for correct fit. Do not use oils or
lubricants. Use only Viega ProPress Yellow HNBR
sealing elements.
4.
Mark proper insertion depth as indicated by the Viega
ProPress Insertion Depth Chart. Improper insertion
depth may result in improper seal.
5.
While turning slightly, slide press fitting onto tubing to
the marked depth.
Note: End of tubing must contact stop.
6.
Insert appropriate Viega jaw into the pressing tool
and push in, holding pin until it locks in place.
7.
Open the jaw and place at right angles on the fitting.
Visually check insertion depth using mark on tubing.
8.
Start pressing process and hold the trigger until the
jaw has engaged the fitting.
9.
After pressing, the jaw can be opened again.
WARNING
The following standards, codes and
!
instructions should be followed when installing Viega
ProPressG fittings for Fuel Gas.
• 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 NFPA 54 or the LP-Gas Code
NFPA 58, as applicable.
• For use with type K or L copper tubing, drawn copper from
½" to 2", and annealed copper from ½" to 1¼". All copper
must be in compliance with ASTM B-88.
• The fittings are for use with fuel gases only and are intended for
operating pressure specified (maximum 125 psi).
• Undue stress or strain on the fittings and the tubing is to be
avoided.
• Concealed tubing and fittings shall be protected from puncture
threats.
• If the installation requires components in addition to those
supplied by the fitting manufacturer, those components
shall be specified. The instructions shall state that only the
components provided or specified by the manufacturer are
to be used in the installation.
• The fitting/tubing system shall not be used as a grounding
electrode for an electrical system.
• The inspection, testing and purging of the installation
shall be performed using procedures specified in Part 4 of
the National Fuel Gas Code NFPA 54, ANSI Z223 or the
LP-Gas Code NFPA 58 section 3.2-10 as applicable, or in
accordance with the requirements of the applicable local
codes.
• For use with natural, propane, mixed and manufactured
gases in the vapor state, not in the liquid state.
• The fitting/tubing system shall not be used as a means of
support.
