  • Page 3: About Us

    HeatLink has developed and manufactured many industry firsts, such as the “TwistSeal“ tool-less manifold in 1996. The company began manufacturing PEX-a tubing in 1998, and now supplies the highest quality PEX-a systems to customers throughout North America, and parts of Europe and Asia.

  • Page 4: Introduction

    Installations must follow all applicable local building and plumbing codes and regulations. The HeatLink® Potable Water Press System features PureLink® Plus PEX-a tubing, high performance polymer (HPP) fittings and multiport tees, no lead fittings, and stainless steel press sleeve connection technology.

  • Page 5: Pex Tubing Ratings

    PureLink® Plus PEX-a tubing is listed with a standard grade rating in PPI TR-4 as tested in accordance with PPI TR-3. PureLink Plus tubing carries the temperature and pressure ratings shown in the table below.

  • Page 6: Plenum Rating

    Plenum Rating PureLink Plus PEX-a tubing has been tested in accordance with CAN/ULC S102.2-2007/2010, Standard for Surface Burning Characteristics of Flooring, Floor Covering and Miscellaneous Materials and Assemblies and ASTM E84, Standard Test Method for Surface Burning Characteristics of Building Materials.

  • Page 7: Product Listings

    It is the sole responsibility of the installer to verify that the product and installation meets local standards. PureLink® Plus PEX-a tubing is approved for use with fittings that are compliant with ASTM F1807/F1960/F2080/F2098/F2159 standards. When using HeatLink tubing with fittings from other manufacturers, ensure to follow all applicable installation requirements and instructions, as well as local building codes to ensure proper connections are made.

  • Page 8: Limitations

    Limitations Limitations on PureLink® PEX Tubing Do Not expose to open flame. Do Not permanently expose to UV light. Do Not use glue, or any material that affects the basic properties of crosslinked polyethylene. Do Not use above ratings. Do Not install within 6" (15 cm) of any gas appliance vent piping, or within 12" (30 cm) of any recessed light fixtures.

  • Page 9: General Repair And Testing

    General Repair and Testing Kinked Tubing Repair One of the most important features of PureLink® PEX-a crosslinked tubing is its shape memory. As such, a kinked area can be repaired using the following procedure: Release system pressure. Straighten portion of tubing being repaired (do not squeeze with pliers).

  • Page 10: Purelink® Installation Guidelines

    PureLink® Installation Guidelines General Practices Install PureLink® PEX at least 12" vertically, or 6" 12" Minimum horizontally away from heat sources such as recessed light Vertical fixtures, or gas appliance vent piping. Distance For UL1598 approved Type IC thermally protected luminaires, clearance can be reduced to 1".

  • Page 11: Expansion And Contraction

    If PureLink® PEX is notched or cut, the damaged section must be cut out. HeatLink approves the burial of PureLink® Plus PEX-a tubing in concrete. HeatLink recommends continuous length tubing (no fittings) when installing PureLink® PEX tubing in or under a slab.

  • Page 12: Pex Tubing Supports

    PEX Tubing Supports HeatLink PEX-a tubing can be supported using the same methods as metallic pipe. HeatLink recommends using copper tube size (CTS) hangers and supports designed for use with plastic pipe, e.g., plastic, coated, rubber, or foam lined, etc. Supports shall not compress, cut or abrade the tubing.

  • Page 14: Expansion & Contraction

    Expansion & Contraction PEX has a high rate of thermal expansion. The design and installation of every piping system shall include means to accommodate its expansion and contraction caused by temperature changes, movement of the soil, building shrinkage or structural settlement. For systems using PEX 1"...

  • Page 15: Corner Offset

    Corner Offset Example 1: A 50ft straight run of 1¼" PEX is anchored at one end, and an elbow is installed at the other end. It is a DHW supply pipe with an operating temperature of 150°F, but was originally installed at 70°F, giving us a difference of 80°F, which equals 4.4" of expansion. In this case a corner offset is the best solution.

  • Page 16: Expansion U Offset

    Expansion U Offset Example 2: There is a 100ft straight run of 2" PEX tubing on a tray in a ceiling space for DHW. Again we need to allow for 100°F of temperature difference. In this case a U offset will work best.

  • Page 17: Pressing Instructions

    Pressing Instructions 1. Inspect all components for debris, obstructions, and/or damage prior to installation. 2. Cut the PEX tubing to length, ensuring a square cut - an irregular cut may ® Pure Link Link Plus result in a failed connection. For larger diameter PEX an ABS cutter is recommended.
