Viega fittings are pressed before, after and on top of the sealing element in a single step, which creates a permanent connection that is secure and guaranteed to last.

1.4 Fitting description

Viega ProPress ttings are offered in more than 600 congurations in copper, bronze, 304 and 316 stainless steel, including: elbows, couplings, ball valves, reducers, tees, reducing tees, threaded adapters, unions, caps and anges. Viega ProPress ttings for Stainless are designed to be used with only Viega’s stainless steel pipe.

1. Viega’s unique, patented Smart Connect feature helps installers ensure that they have pressed all connections.

2. Viega offers three different sealing elements to suit virtually any application: EPDM, HNBR and FKM.

3. Viega’s distinctive hexagonal pressing pattern bonds fitting and pipe and provides the mechanical strength for the connection.

4. All Viega ProPress fittings are designed with cylindrical pipe guides to keep the pipe straight and protect the sealing element during assembly.

1.4.1 Viega large-diameter ﬁttings

Viega 2½" to 4" ttings feature an EPDM or FKM sealing element, stainless steel grip ring and PBT separator ring as shown in Figure 1.1.

The grip ring comes standard in all 2½" to 4" fittings. The grip ring is a stainless steel ring with teeth, which grips the tube and ensures that the fitting is locked securely in place.

The PBT (Polybutylene Terephthalate) separator ring ensures that the sealing element and grip ring perform at a maximum capacity by providing a positive physical separation.

Whether working with stainless steel or copper, ProPress XL fittings are designed to be pressed

with RIDGID’s XL-C press rings and V2 actuator. This will produce a non-detachable, permanent connection.

Fittings that do not have cylindrical pipe guides risk making an unsecure connection. Without the pipe guides, installers can possibly damage the sealing element.

1.4.2 Pipe

Viega stainless steel pipe is offered in either 304 stainless or 316 stainless to complement the Viega ProPress for stainless fittings and offer a complete system solution. Viega stainless steel pipe meets the requirement of ASTM A312 or ASTM A554 for schedule 5 304 and 316 stainless steel pipe.

IM-PP 724607 0815

1.4.3 Special features

Viega ProPress copper, 316 stainless steel and Zero Lead bronze fittings meet the federal lead-free requirements of NSF 61-G through testing under NSF/ANSI 372 (0.25% or less maximum weighted average lead content). Fast and easy; one squeeze of the trigger makes the connection on any size tube in four to seven seconds.

1.4.4 Viega Smart Connect feature

In Viega ProPress ½" to 4" fittings, the Smart Connect feature (Figure 1.2) assures the escape of liquids 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 identification of connections that have not been pressed prior to putting the system into operation (Figure 1.4).

Figure 1.2: The Smart Connect feature of Viega press fittings is color marked on the bead

When the fitting is pressed (Figure 1.3), a permanent, sealed, non-detachable, mechanical connection is created.

Figure 1.3: Section of a press fitting in unpressed (A) and pressed (B) condition

Unpressed fittings from other manufacturers, without the patented Smart Connect feature, may not leak during the initial system pressure test. However, they can unseat in future system operation. The Smart Connect feature is designed to protect from this potential risk.

Figure 1.4

when water flows past the sealing element.

Upon identification, use the press tool to press the fitting,

making a permanent leakproof connection.

Viega ProPress connections are fast, flameless and guaranteed.

1.4.5 Sealing elements

Viega ProPress EPDM sealing element

Operating temperature: 0°F to 250°F (-18°C to 120°C)

Viega ProPress and ProPress for stainless 316 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 ethylenepropylene dienemonomer, is shiny black in color. The EPDM sealing element is a synthetically manufactured and peroxide cross-linked, general-purpose elastomer with a wide range of applications.

It possesses excellent resistance to aging, ozone, sunlight, weathering, environmental influences, most alkaline solutions and chemicals used in a broad range of applications.

The EPDM sealing element has particularly good resistance to hot water, making it ideal for seals and gaskets in heating systems, fittings and household appliances (e.g. washing machines, pumps, dishwashers).

All sealing elements are inserted into the fitting using an H1 Grade lubricant registered with NSF, the USDA and approved for use under FDA 21 CFR.

Viega ProPress FKM sealing element

Operating temperature: 0°F to 284°F (-18°C to 140°C)

FKM is well known for its excellent resistance to petroleum products and solvents as well as exceptional high-temperature performance. The FKM sealing element is a special-purpose elastomer typically installed where higher temperatures are required.

FKM, a fluoroelastomer, is dull black in color. It possesses excellent resistance to aging, ozone, sunlight, weathering, environmental influences, oils and petroleum-based additives. Its superb resistance to high temperatures and petroleum-

IM-PP 724607 0815

Page 8

based additives makes it ideal for seals and gaskets in solar, district heating, low-pressure steam and compressed air system fittings. It can withstand heat spikes up to 356°F.

Viega ProPress HNBR sealing element

This sealing element is used mainly for applications of natural gas, propane, mixed and manufactured fuel gases in the vapor state (not in the liquid state). It is commonly used in fuel oil heating systems. HNBR, or Hydrogenated Nitrile Butadiene Rubber, is yellow in color for easy identification.

Ambient operating temperature:

-40°F to 180°F (-40°C to 82°C)

HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat, oil and chemicals.

The unique properties attributed to HNBR have resulted in wide adoption of HNBR in automotive, industrial and assorted high-performance applications (e.g. engine seals, grommets, gaskets, fuel system seals and hoses, transmission system bonded piston seals, oil field packers and rotary shaft seals).

With its excellent performance for the most demanding of applications, HNBR is the ideal choice for applications needing excellent physical properties as well as oil, heat and/or chemical resistance.

3 General Installation Instructions

3.1 Tube selection

3.1.1 Viega ProPress

Viega ProPress copper and copper alloy ttings are compatible with ½" to 1¼" soft copper tube and ½" to 4" hard copper tubing types K, L and M. All copper tubing that is to be used with Viega ProPress copper and bronze ttings must comply with ASTM B88 standards.

Note: Tubing shall be free of surface imperfections including metal stamped print lines.

3.1.2 Viega ProPressG

Viega ProPressG fuel gas installations can be made with seamless, drawn copper tubing. These tubes must comply with the requirements of ASTM B88.

Types K and L copper tube (ASTM B88) have been used in fuel gas systems for many years. Type L is typically used for interior distribution systems and type K for any underground lines.

Designers and installers should be specific with size designations in their references and when ordering. Copper tubing 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. The allowable limits are below those specified in the model codes and below the amounts that would adversely affect copper tubing. Copper tubing can be installed in all areas of construction, including concealed spaces.

Viega ProPressG and copper tubing is approved for underground installations. However, any installations must meet all state and local codes, including those for underground. Proper authorization must be obtained prior to underground installation from the local Authority Having Jurisdiction. Viega ProPressG and copper tubing may be installed outside without any additional corrosion protection.

In residential applications, copper tubing with Viega ProPressG fittings can be used to run fuel gas from the meter or source to furnaces, boilers, gas ranges, water heaters, gas fireplaces, clothes dryers, outdoor barbecues and decorative lighting.

Copper tubing can be easily installed in wall and floor cavities. When retrofitting an installation in a home with copper tubing using Viega ProPressG fittings is easier, faster and less expensive than installing threaded steel pipe or CSST.

For commercial construction, copper tubing using Viega ProPressG fittings may be installed for gas lines to air handling units, boilers, water heaters and many other gas appliances. For rooftop installations, copper tubing with Viega ProPressG fittings can be installed either on or below the roof. When installed on the roof, the copper tubing does not have to be coated or covered since the material is naturally corrosion resistant.

3.1.3 Viega ProPress for Stainless

Only Viega stainless tubing is approved for installation with Viega ProPress for Stainless fittings. This is to ensure reliability and conformity with the stainless steel system. Viega ProPress for Stainless pipe comes in sizes ½" to 4".

General

Viega ProPress for Stainless tubing is thicker than schedule 5, inert gas welded pipes, meeting ASTM A312, A554 and DIN 1988 wall thickness requirements.

Delivery condition

All dimensions are delivered in sticks that are nominal 20 ft. in length, with a metallic bare exterior and interior surface. The sticks are free from annealing color and corrosion-promoting substances.

All tubing has been tested for leaks and is subject to continuous quality monitoring, as well as external monitoring by the material testing office.

3.4.3 Soldering or brazing near an existing Viega ProPress ﬁtting

To ensure proper sealing of the soldered/brazed joint and the press connection, a minimum distance between connections must be maintained.

When soldering near a Viega ProPress connection, the installer must remain at least three tube diameters away from the connection to prevent damage to the sealing element. When brazing, the installer must remain at least nine tube diameters away from the connection. Refer to Table 3.4.

The installer should take precautions to keep the Viega ProPress connection cool. These include:

• Wrapping the connection with a cold wet rag

• Fabricating solder connections prior to

installing the press tting, making sure the tube has cooled before installing the tting

• Applying “spray type” spot freezing

It is particularly important to ensure the tubing inserted into the Viega ProPress fitting and the Viega ProPress fitting are not exposed to excessive heat.

3.4.4 Welding adjacent to a Viega ProPress ﬁtting

When welding pipe adjacent to pipe joined with a Viega ProPress tting, installers must weld 4" away from the Viega ProPress connection to protect the sealing element. Precautions installers can take to keep the Viega ProPress connection cool include:

• Wrapping the connection with a cold wet rag

• Protecting the connection with a weld blanket

• Prefabricating welded connections prior to

installing the pressed tting

• Making sure the pipe has cooled before installing the tting

• Consistently applying “spray type” spot freezing

3.4.5

Welding in line with a Viega ProPress ﬁtting

When welding on the same pipe as a Viega ProPress tting, installers must weld at least three feet away from the Viega ProPress connection to protect the sealing element. If three feet is not possible, installers should follow the precautions listed above to keep the Viega ProPress connection cool.

Distance

IM-PP 724607 0815

Page 18

3.5 General installation requirements

The Viega ProPress fitting system must be installed while considering the following general industry requirements.

3.5.1 Expansion

Thermal expansion in installed systems generates stresses in pipes and appliance connectors. Compensation must allow for expansion and contraction that may occur within the piping system. Expansion joints or mechanical expansion compensators may be used to alleviate these stresses.

3.5.2 Electrical bonding

When properly installed, Viega ProPress fittings comply with section 1211.15, Electrical Bonding and Grounding, of the Uniform Plumbing Code and section 310 of the International Fuel Gas Code. The mechanical press provides continuous metalto-metal contact between fitting and pipe. The press ensures continuity of bonding through this contact.

3.5.3 Piping exposed to freezing temperatures

In the Viega ProPress system, the EPDM sealing element can be installed in ambient temperatures down to 0°F. The HNBR sealing element available with Viega ProPressG fittings can be installed in ambient temperatures down to -40°F. Piping systems exposed to freezing temperatures must be protected per acceptable engineering practices, codes and as required by the local Authority Having Jurisdiction.

3.5.4 Corrosion protection

Viega ProPress fittings exposed to corrosive action, such as soil conditions or moisture, must be protected in an approved manner in accordance with NFPA 54 section 404.8, NACE Standard RP0169-2002 section 5, 2009 UPC Chapter 6 section 609.3.1, 2009 UMC Chapter 13 section

1312.1.3 and in a manner satisfactory to the local Authority Having Jurisdiction. Care should be taken to select hangers of suitable material that is galvanically compatible with the piping system. In addition, piping systems should be properly sized to minimize the risk of erosion corrosion resulting from excessive velocities.

3.5.5 Concealed spaces

Viega ProPressG was examined according to the construction and performance criteria in the CSA requirement LC-4 and was found acceptable. Specific performance tests were conducted to evaluate the fittings for use in concealed locations.

3.5.6 Underground installations

Viega ProPress fitting systems with copper tubing are approved for underground installations. However, any installations must meet all state and local codes, including those for underground.

Proper authorization must be obtained prior to installation from the local Authority Having

Jurisdiction.

3.5.7 Pressure testing

The pressure testing of installed pipe is to be completed in accordance with local codes or Authority Having Jurisdiction. For Viega ProPressG, in the absence of local codes, test according to NFPA

54 or NFPA 58. Viega recommends air testing of gas systems to be a minimum of ½ psi.

The Viega Smart Connect feature is a quick and easy way for installers to identify connections that need to be pressed. Testing for leaks using the Viega Smart Connect feature is not a replacement for testing to the requirements of local codes or standards.

Water testing the Viega Smart Connect feature:

When testing the system with water, a pressure range of 15 psi - 85 psi maximum is to be used. If an unpressed fitting is found, check to make sure the tubing is fully inserted before completing the press. Following a successful leak test, the system may be pressure tested up to 600 psi for water if required by local code requirements or project specifications.

Air testing the Viega Smart Connect feature:

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 maximum for air if required by local code requirements or project specifications.

3.5.8 Pipe hangers and supports

Pipe supports perform two functions. The first function is to provide support for the piping system.

The second function is to guide the pipe or tube during thermal expansion and contraction. Industry standard practices and guidelines shall be used for piping layout and support. Viega press connections require no special consideration for support.

Hangers and supports must conform to the local code requirements. In the absence of local code requirements, hangers and supports must conform to ANSI/MSS SP 58 Pipe Hangers and Supports Materials, Design, Manufacture, Selection, Application and Installation. Supports, hangers and anchors are to be installed in a manner that does not interfere with the free expansion and contraction of the piping.

IM-PP 724607 0815

Page 19

All parts of the support equipment need to be designed and installed to not disengage due to movement of the supported piping. Sliding hangers must be positioned so that they cannot unintentionally become rigid hangers when the system is in use. See Figure 3.1. Figure 3.2 shows a sliding pipe hanger that becomes a rigid hanger with spacing in excess of 10".

Figure 3.1 Spacing for sliding pipe hanger

Figure 3.2 Spacing for sliding pipe hanger

At no point in the piping system should a fitting be the sole means of support. For example, when installing a tee, both the branch and the trunk must be properly supported. Piping systems should be isolated from shock and vibration through the proper use of hangers, supports and vibrationeliminating devices.

3.5.9 Pressure surges

The maximum operating pressure in a ProPress system is 200 psi; this is a working limit and applies to general operation as well as pressure transients. Good engineering practices should be utilized to design the system in a way that minimizes sharp pressure surges. Pressure surges or transients from fast acting valves, pump surges and other sources that result in water hammer effects can cause damage to many system components, including press ttings. When fast acting valves and/or pumps are incorporated into any system, the designer and installer should isolate press ttings from the effects of sharp pressure surges. ProPress ttings should be isolated or separated by sufcient distance from pumps, fast acting valves and other sources of pressure transients.

3.6 Viega ProPress installation requirements

The following are special requirements to consider when installing the Viega ProPress fitting system.

3.6.1 Rotating a pressed ﬁtting

Once a Viega ProPress fitting has been pressed, it can be rotated (not by hand), but once rotated more than five degrees, the fitting must be re-pressed to restore resistance to rotational movement. If the fitting is re-pressed, care should be taken to align the flats on the jaw and fitting.

3.6.2 Deﬂection

When pressing Viega ProPress fittings in a system, the deformation of the fitting is constant. This allows for a consistent leak-free joint every time and is a result of the pressing technique.

The pressing process can cause deflection (angular misalignment) to occur. Deflection while pressing can be corrected by alternating the position of the press tool on each fitting connection. An example would be placing the press tool on the right side of the first press connection and alternating to the left side of the press fitting on the second connection.

While deflection cannot be completely eliminated, it can be minimized using this method.

3.7 Identification

All Viega ProPress piping systems should be continuously marked in accordance with ANSI A13.1 or as required by the local Authority Having Jurisdiction.

Leak Testing with Smart Connect

Unpressed connections are located by pressurizing the system with air or water. When testing with water the proper pressure range is 15 psi to 85 psi maximum.

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 with air, or up to 600 psi with water, if required by local code requirements or project specications.

4 Warranty

4.1 Limited warranty for Viega ProPress fittings and valves

Subject to the conditions and limitations in this Limited Warranty, Viega LLC (Viega) warrants to wholesalers and licensed plumbing and mechanical contractors in the United States and Canada that its Viega ProPress fittings, when properly installed in non industrial and non marine applications and under normal conditions of use, will be free of failure from manufacturing defect for a period of fifty (50) years from date of installation and that its Viega ProPress valves, when properly installed in non industrial and non marine applications and under normal conditions of use, will be free of failure from manufacturing defect for a period of two (2) years from date of installation.

Under this Limited Warranty, you only have a right to a remedy if the failure or leak resulted from a manufacturing defect in the products covered by this warranty and the failure or leak occurred during the warranty period. You do not have a remedy under this warranty and the warranty does not apply if the failure or any resulting damage is caused by (1) components other than those manufactured or sold by Viega; (2) not designing, installing, inspecting, or testing the Viega ProPress fittings or valves in accordance with Viega’s installation instructions in effect at the time of the installation; applicable code requirements; and accepted industry practice; (3) improper handling and protection of the product prior to and during installation, inadequate freeze protection, exposure to water pressures or temperatures or in applications outside acceptable operating conditions; (4) acts of nature such as, but not limited to, earthquakes, fire, flood, or lightning, or (5) external environmental causes, such as water quality variations, aggressive water, or other external chemical or physical conditions.

In the event of a leak or other failure of the parts covered by this warranty, it is the responsibility of the property owner to obtain and pay for repairs. Only if the warranty applies will Viega be responsible for the remedy under this warranty. The part or parts which you claim failed should be kept and Viega contacted by writing to the address below or telephoning 1-800-976-9819 within thirty (30) days after the leak or other failure and identifying yourself as having a warranty claim. You should be prepared to ship, at your expense, the product which you claim failed due to a manufacturing defect and document the date of installation. Within a reasonable time after receiving the product, Viega will investigate the reasons for the failure, which includes the right to inspect the product at Viega. Viega will notify you in writing of the results of its review.

In the event that Viega determines that the failure or leak was the result of a manufacturing defect in the part covered by this warranty and that this warranty applies, the EXCLUSIVE AND ONLY REMEDY under this warranty shall be the reimbursement for repair and/or replacement of the part. VIEGA SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL OR OTHER DAMAGE (FOR EXAMPLE, WATER OR PROPERTY OR MOLD REMEDIATION) UNDER ANY LEGAL THEORY AND WHETHER ASSERTED BY DIRECT ACTION, FOR CONTRIBUTION OR INDEMNITY OR OTHERWISE.

THE ABOVE WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. If a limited warranty shall be found to apply, such warranty is limited to four years. Other than this Limited Warranty, Viega does not authorize any person or firm to create for it any other obligation or liability in connection with its products.

This Limited Warranty gives you specific legal rights and you also may have other rights which may vary from state to state. This warranty shall be interpreted and applied under the law of the state in which the product is installed and is intended as a Commercial Warranty.

For purposes of this warranty, industrial applications are defined as non residential and non commercial applications not normally accessible to the general public.

Under this Limited Warranty, you only have a right to a remedy if the failure or leak resulted from a manufacturing defect in the Viega product and the failure or leak occurs during the warranty period.

Final approval as to use compatibility to a specific process or fluid application is the responsibility of the engineer of record or responsible design/facilities personnel and this Limited Warranty only applies to manufacturing defects in the Viega Product.

In the event of a leak or other failure in the Viega product covered by this warranty, it is the responsibility of the end user to take appropriate measures to diminish any damage, to include making timely repairs.

VIEGA SHALL NOT BE LIABLE FOR CONSEQUENTIAL OR OTHER DAMAGE (FOR EXAMPLE, ECONOMIC LOSS, WATER OR PROPERTY OR MOLD REMEDIATION) UNDER ANY LEGAL THEORY AND WHETHER ASSERTED BY DIRECT ACTION, FOR CONTRIBUTION OR INDEMNITY OR OTHERWISE.
