1. SYSTEM DESCRIPTION 1.1 Viega Metal Systems General Viega Metal Systems is the state-ofthe-art press fitting system that provides an economical and reliable installation of metal tubing for the commercial, industrial and marine markets. The Systems Our products are the result of decades of experience in manufacturing fittings. Viega Metal Systems are offered in the following configurations: ProPress: Copper and Zero Lead Bronze Alloy fittings in inch copper tube size (CTS) with Smart Connect® feature.
World’s Largest Selection of Fittings There are more than 3,000 different engineered fittings available in a variety of materials, configurations and sizes. Professional Appearance Because there is no buildup of joining material, exposed threads, or tarnish, Viega Metal System connections have a clean, professional look. Less Equipment With Viega Metal Systems there is no need to buy or carry expensive cumbersome equipment. Welding tanks and threading machines are a thing of the past.
2. SEALS AND GASKETS 2.1 EPDM Sealing Element Operating temperature: 0°F to 250°F (-18°C to 120°C) Viega Metal Systems press fittings are manufactured with a high-quality EPDM sealing element installed at the factory. This sealing element is used mainly in the applications of potable water, hydronic heating, fire sprinkler and compressed air installations. EPDM, or ethylene-propylene dienemonomer, is shiny black in color.
3. SMART CONNECT FEATURE 3.1 Viega Smart Connect Feature In ProPress 1/2" to 4" dimensions, the Smart Connect® feature (Fig. 3.1) assures leakage of liquids and/or gases from inside the system past the sealing element of an UNPRESSED connection. The function of this feature is to provide the installer quick and easy identificaiton of connections that have not been pressed prior to putting the system into operation (Fig. 3.3). 3.
4. PRESS TOOLS 4.1 Tools Viega recommends RIDGID press tools, ProPress jaws and ring sets manufactured and sold by RIDGID Tool Company for Viega Systems. ® ® 4.
5. GENERAL INSTALLATION INSTRUCTIONS 5.1 Minimum Distance Between Fittings Minimum distance between two Viega ProPress XL® press connections 2-1/2" to 4" To prevent distortion of the pipe, fittings require a minimum distance between fittings (refer to chart below). Failure to provide this distance may result in an improper seal. Note: ProPress systems include XL (Bronze) and XL-C (Copper) fittings. All other systems denote XL fittings as the same material as the piping (i.e.

5.4 Transition Connections Threaded Connections amin The Viega Metal Systems 1/2" – 4" can be joined with off-the-shelf threaded fittings (thread in accordance with DIN 2999) or armatures made of non-ferrous metals. In this regard: j The threaded connection is made first. k The press fitting is made. This process avoids unnecessary torsion. Flange Connections When using Viega flanges, bolt the flange end in place prior to pressing the fitting to the tubing. 5.

12. PROPRESSG™ 12.1 Welcome 12.2 Intent 12.3 History By choosing to install a CSA LC-4 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.
13. SYSTEM DESCRIPTION 13.1 System Description ProPressG is a copper press connection system designed to meet the demands of natural gas and liquid propane gas in the vapor state, as well as fuel oil systems. Press fittings are manufactured in copper and bronze and fittings with NPT connections are manufactured in bronze. ProPressG fittings use an HNBR sealing element to provide permanent leak-proof connections in dimensions from 1/2" to 2". All fittings have a built-in Smart Connect Feature.
14. PROPRESSG APPLICATIONS 14.1 Fuel Gas Systems All ProPressG fittings have a factory installed HNBR sealing element that can be installed in ambient temperature ranges from -40°F (-40°C) to 180°F (82°C) and a maximum operating pressure of 125 psi (8.6 bar), making them suitable for many applications. ProPressG fittings are approved for installations in above and below ground applications.
15. PRODUCT DESCRIPTION 15.1 Fittings Viega ProPressG Fittings are currently offered in more than 120 fitting configurations. ProPressG fittings are manufactured in copper and bronze and are available in sizes ranging from 1/2"to 2". Every fitting is provided with a factory installed HNBR sealing element. In addition, all fittings include our patented Smart Connect feature.
Designers and installers should be specific with size designations in their references and when ordering. Copper and copper alloy tube should not be used if the gas contains more than an average of 0.3 grains of hydrogen sulfide per 100 standard cubic feet (scf) of gas (0.7 mg/100 L). Today, federal regulations limit the amount of hydrogen sulfide allowed in natural gas transmission.
1/2 - 85 psi. The Smart Connect feature test is not a substitute for local code required pressure testing. The final pressure test is to be carried out in Figure 15.3: Cross-section through a ProPressG connection after pressing Figure 15.1: Smart Connect feature in ProPressG 1/2" to 2" fittings. accordance with local codes. 15.5 Press Connections The pressing process provides a simple, safe and reliable means of connecting copper tubing for fuel gas systems with ProPressG fittings as shown in figure 15.

16. INSTALLATION REQUIREMENTS 16.1 Clearance Requirements Minimum clearance requirements for the pressing process Table 16.2: Space requirements for press jaws between pipe and wall/ floor structure c The minimum clearance required between two tubes and between the tubing and any permanent structure must be taken into consideration. The minimum allowable values are specified in Tables 16.1 and 16.2.
diagonal to the joists may be installed through holes drilled through the center of the joists. These holes must be a minimum of 1-1/2 times the O.D. of the tubing. See Table 16.5 for more information. This is to permit the movement of the appliance. When connecting a copper tubing fuel gas piping system to a steel pipe, cast bronze ProPressG fittings must be used. These bronze fittings provide protection from galvanic action. 16.
movement of the tubing. However, all systems must be installed per local code requirements. ≥ 4" of the tubing. All parts of the support equipment need to be designed and installed, not to disengage by movement of the supported tubing. Sliding hangers must be positioned so that they cannot unintentionally become rigid hangers when the system is in use. Fig. 16.3 shows a sliding tubing hanger that becomes a rigid hanger with spacing in excess of 10". Table 16.6: Hanger Spacing Tube Nominal Tube Copper Max.
Specific identification must meet the requirements of the applicable local codes. Each system, however, must be clearly marked with appropriate labels to identify that it is a gas system, the type of the system (low pressure, elevated pressure) and for elevated pressure systems, the system delivery pressure. The low pressure system can use the label shown in Figure 16.7 while the high pressure system can use markings similar to that shown in Figure 16.8.

17. SYSTEM DESIGN AND SIZING 17.1 System Design ProPressG fittings and copper tubing may be used in any fuel gas piping systems where the quality of the fuel gas has less than or equal to 0.3 grains of hydrogen sulfide per 100 standard cubic feet of gas (0.7 milligrams per 100 liters). Information regarding fuel gas quality may be obtained from the local gas supplier. For natural gas, contact the local gas utility. For liquid propane gas, contact the liquid propane gas supplier.
brace or bracket and run copper tube through to the outside allowing service personnel to be aware that it is a semi-rigid system and damage can be avoided. The connection between the steel system and copper system does not create a corrosion concern if the connection is made in a dry location or a location that does not allow moisture to collect at the connection. The absence of continuous moisture prevents the occurrence of galvanic action and subsequent corrosion of the steel pipe.
The main runs of piping are still sized based on the longest length and total load method. Each branch can then be individually sized. The length of piping to apply when using the table is the length of piping from the point of delivery to the most remote appliance in the branch including both horizontal and vertical piping.
